Meet the staff of the Micronutrient Information Center. If you value this website, please help by donating to the MIC. Vitamin A is a generic term that encompasses a number of related compounds Figure 1.
Retinol and retinyl esters are often referred to as preformed vitamin A. Retinol can be converted by the body to retinal, which can be in turn be oxidized to retinoic acid, the form of vitamin A known to regulate gene transcription. Retinol, retinal, retinoic Zeder Psoriasis, and related compounds are known as Zeder Psoriasis. The following discussion will focus mainly on preformed vitamin A compounds and retinoic acid.
Vitamin A compounds are essential fat-soluble molecules predominantly stored in the liver in the form of retinyl esters e. When appropriate, retinyl esters are hydrolyzed to generate all- trans -retinol, which binds to retinol binding protein RBP before being released in the bloodstream.
Vitamin A as retinyl esters in chylomicrons was also found to have an appreciable role in delivering vitamin A to extrahepatic tissues, especially in early life 3, 4. Zeder Psoriasis particles of light that pass through the lens are sensed by the photoreceptor cells of the retina Zeder Psoriasis converted to nerve impulses electric signals for interpretation by the brain.
All- trans -retinol is transported to the retina via the circulation and accumulates in retinal pigment epithelial RPE cells Figure 2 5.
Here, all- trans -retinol is esterified to form here retinyl ester, which can Zeder Psoriasis stored. When needed, retinyl esters are broken apart hydrolyzed and isomerized to form cis -retinol, which can be oxidized to form Zeder Psoriasis -retinal. In rod cells, cis -retinal binds to a protein called opsin to form the visual pigment rhodopsin also known as visual purple.
Absorption of a photon of light catalyzes the isomerization of cis -retinal to all- trans -retinal that is released from the opsin molecule. All- trans -retinal is converted to all- trans -retinol and transported across the interstitial space to the RPE cells, thereby completing the visual cycle. A similar cycle occurs in cone cells that contain red, green, or blue opsin proteins http://gsyaml.de/enterosgel-bewertungen-fuer-psoriasis.php for the absorption Zeder Psoriasis photons from the visible light spectrum 2.
Vitamin A is also essential for mammalian eye development 6. Thus, because vitamin A is required for the normal functioning of the retina, dim-light Zeder Psoriasis, and color vision, inadequate retinol and retinal available to the retina result in impaired dark adaptation.
In the severest cases of vitamin A deficiency, thinning and ulceration of the cornea leads to blindness see Deficiency. In cells, all- trans -retinol can be either stored in the form of retinyl ester or oxidized to Zeder Psoriasis trans -retinal by alcohol dehydrogenases.
In turn, retinaldehyde dehydrogenases can catalyze the conversion of Zeder Psoriasis trans -retinal into two Zeder Psoriasis active isomers of retinoic acid RA: RA isomers act as hormones to affect Zeder Psoriasis expression and thereby influence numerous physiological processes. All- trans -RA and 9- cis -RA are transported to the Zeder Psoriasis of the cell bound to cellular retinoic acid-binding proteins CRABP.
Within the nucleus, RA isomers bind to specific nuclear receptor proteins that are ligand -dependent transcription factors Figure 3. The activation of RAR by RA binding triggers the recruitment of transcriptional coregulators to target promoters, thereby inhibiting or allowing the transcription of genes 8. RXR also forms Zeder Psoriasis with several other nuclear receptors, including thyroid hormone receptor TRvitamin D receptor VDRsteroid receptors, and peroxisome proliferator-activated receptor PPAR 9.
In this way, vitamin A may interact with thyroid hormone, vitamin D, steroids e. In retinoblastoma cells, RAR was also involved in RA-induced activation of signaling cascades mediated by tyrosine kinases known as phosphoinositide 3-kinase PI3K and Zeder Psoriasis to cell differentiation 11, Phosphorylated CREB can subsequently bind to the CREB response element in the promoter of genes involved in cell differentiation Hence, RA can influence Zeder Psoriasis expression of genes whose promoters do not contain RARE.
By regulating the expression of over retinoid-responsive genes including several genes involved in vitamin A metabolism itselfretinoic acid isomers play major roles in cellular proliferation and differentiation i.
STRA6 also Zeder Psoriasis with lecithin: Interestingly, retinol uptake by STRA6 was found to trigger the activation of a signaling cascade mediated by tyrosine kinases known as Janus kinases JAK and associated transcription factors Zeder Psoriasis. Apart from its role as a ligand for opsin in the visual cascade see Visual system and eyesightretinal has been specifically implicated in the regulation of genes Zeder Psoriasis for lipid metabolism.
In humans, two types of adipose tissue have been distinguished based on their respective functions: In the mitochondrial respiratory chain of brown adipose cells, the processes of electron transport and ATP production are uncoupled dissociated to permit Zeder Psoriasis rapid production of heat from fatty acid oxidation Retinaldehyde dehydrogenase 1 RALDH1which converts retinal to retinoic acid, is Zeder Psoriasis expressed in WAT but not in BAT.
The suppression of RALDH1 expression Zeder Psoriasis WAT can induce a thermogenic phenotype resembling that of BAT In addition, retinal was Zeder Psoriasis to inhibit gluconeogenic gene expression and glucose production in the liver of mice deficient in RALDH1 Retinoic acid RA is produced by antigen -presenting cells APCsincluding macrophages and dendritic cellsfound in these mucosal interfaces and associated lymph nodes.
RA appears to act on dendritic cells themselves to regulate their differentiation Zeder Psoriasis, migration, and antigen-presenting Zeder Psoriasis. There is also substantial evidence to suggest that RA may help prevent the development of autoimmunity reviewed in Both vitamin A excess and deficiency are known to cause birth defects.
Retinoid signaling begins soon after the early phase of embryonic development known as gastrulation. During fetal development, RA is critical for the development of organs, including the heart, eyes, ears, lungs, as Zeder Psoriasis as other limbs and visceral organs.
Vitamin A has been implicated in fetal lung maturation 2. Vitamin Zeder Psoriasis status is lower in preterm newborns than in full-term infants There is some evidence to suggest that vitamin A supplementation may help reduce the incidence Zeder Psoriasis chronic lung disease and mortality in preterm newborns see Disease Prevention. Retinoid signaling is also involved in the expression of many proteins of the extracellular matrix ECM; material surrounding cellsincluding collagenlaminin, and proteoglycans Vitamin A deficiency may then result in alterations of the ECM composition, thus disrupting organ morphology and function reviewed in Red blood cells erythrocyteslike all blood cells, are derived from pluripotent stem cells in the bone marrow.
Studies involving in vitro culture systems have suggested a role for retinoids in stem cell commitment and differentiation to the red blood cell lineage. Retinoids might also regulate apoptosis programmed cell death of red blood cell precursors erythropoietic Zeder Psoriasis cells However, whether retinoids regulate erythropoiesis in vivo has not http://gsyaml.de/psoriasis-und-haarbehandlung.php established.
Yet, vitamin A Zeder Psoriasis in vitamin A deficient-individuals has been shown to increase hemoglobin concentrations. Additionally, vitamin A appears Zeder Psoriasis facilitate the mobilization of iron from Zeder Psoriasis sites to the developing red blood cell for incorporation into hemoglobin, the oxygen carrier in red blood cells 27, Zinc deficiency is thought to interfere with vitamin A metabolism in several ways The health consequences of zinc deficiency on vitamin A nutritional status in humans are yet to be defined Vitamin A deficiency Zeder Psoriasis coexists with iron deficiency and may exacerbate iron deficiency anemia by altering iron metabolism Vitamin A supplementation has beneficial effects on iron deficiency anemia and improves iron nutritional status among children and pregnant women 27, The combination of supplemental vitamin A and iron Zeder Psoriasis to reduce anemia more effectively than Zeder Psoriasis supplemental iron or vitamin A alone Moreover, studies in rats have shown that iron Zeder Psoriasis alters plasma and liver levels of vitamin A 32, Vitamin A deficiency usually results from inadequate intakes of vitamin A from animal products Zeder Psoriasis preformed vitamin A and fruit and vegetables as provitamin A carotenoids.
In Zeder Psoriasis countries, vitamin A deficiency and associated disorders predominantly affect children and women of reproductive age. Subclinical vitamin A deficiency is often defined by serum retinol concentrations lower than 0. In severe vitamin A deficiency, vitamin A body stores are depleted and serum retinol concentrations fall below 0. Other biomarkers have been calibrated to assess vitamin A nutritional status reviewed in With an estimated Zeder Psoriasis, tochildren becoming blind annually, vitamin A deficiency constitutes the leading preventable cause of blindness in low- and middle-income nations The earliest symptom of vitamin A deficiency is impaired dark adaptation known as night blindness or nyctalopia.
Severe or prolonged vitamin A deficiency eventually results in a condition called xerophthalmia Greek for dry eyecharacterized by changes in the cells of the cornea clear covering click the following article the eye that ultimately result in corneal ulcers, scarring, and blindness Immediate administration ofinternational units IU of vitamin A for two consecutive days is required to prevent blinding xerophthalmia There is an estimated The prevalence of vitamin A deficiency and night blindness is especially high during the third trimester of pregnancy due to accelerated fetal growth.
Moreover, half of the children affected by severe vitamin A deficiency-induced blinding xerophthalmia are click here to die within a year of becoming blind Infectious diseases have been associated with depletion of vitamin A hepatic reserves already limited in vitamin A-deficient subjectsreduced serum retinol concentrations, and increased loss of vitamin A in the urine Infection with the measles virus was found to precipitate conjunctival and corneal damage, leading to blindness in children with poor vitamin A status Conversely, vitamin A deficiency can be considered a nutritionally acquired immunodeficiency disease Even children who are only Zeder Psoriasis deficient in vitamin A have a higher incidence of respiratory complications and diarrhea, as well as a higher rate of Zeder Psoriasis from measles infection compared to children consuming sufficient vitamin A Because vitamin A supplementation may decrease Zeder Psoriasis the severity and incidence of measles go here in developing countries see Disease PreventionWHO recommends that children aged at least one year receiveIU of vitamin A 60 mg RAE for two consecutive days in addition to Zeder Psoriasis treatment when they are infected with measles virus and live in areas of vitamin A deficiency A recent prospective cohort studyconducted in 2, Colombian children ages, years old followed for a median days, also reported an inverse relationship between Zeder Psoriasis retinol concentrations and rates of diarrhea with vomiting and cough with fever, the latter being a strong predictor of influenza infection flu A review of five randomizedplacebo -controlled studies that included 7, HIV -positive pregnant or Zeder Psoriasis women found no substantial benefit of vitamin A supplementation in reducing the click the following article transmission of HIV One early observational study found that HIV-infected women who were vitamin A deficient were three to four times more likely to transmit HIV to their infants Yet, no Zeder Psoriasis to date Zeder Psoriasis provided any information on potential adverse effects of vitamin Zeder Psoriasis supplementation on mother-to-child HIV transmission The response to iodine prophylaxis in iodine-deficient populations appears to depend on various nutritional factors, including vitamin A status 49, Zeder Psoriasis A deficiency in animal models was found to interfere with the pituitary - thyroid axis by 1 increasing the synthesis and secretion of thyroid-stimulating hormone TSH by the pituitary gland, 2 increasing the size of the thyroid gland, Zeder Psoriasis reducing iodine uptake by the thyroid gland and impairing the synthesis and iodination of thyroglobulin, and 4 increasing circulating concentrations of Zeder Psoriasis hormones reviewed in A cross-sectional study of children with concurrent vitamin A and iodine deficiencies found that the severity of vitamin A deficiency was associated with higher risk of goiter and higher concentrations of circulating TSH and Zeder Psoriasis hormones These children received iodine-enriched Zeder Psoriasis with either vitamin AIU at baseline and 5 months or placebo in a randomizeddouble-blind Zeder Psoriasis, month trial.
This vitamin A supplementation significantly decreased TSH concentration and read article volume compared to placebo In another trial, supplementation of vitamin A to iodine-deficient children had no additional effect to iodine on thyroid status compared Zeder Psoriasis placebo, but vitamin A supplementation alone without iodine reduced Zeder Psoriasis volume of the thyroid gland, as well as TSH and thyroglobulin concentrations Zeder Psoriasis Phrynoderma or follicular hyperkeratosis is a skin condition characterized Zeder Psoriasis an excessive production of keratin in hair follicles.
The lesions first appear on the extremities, shoulders, and buttocks and may spread over the entire body in the severest cases While vitamin A deficiency may contribute to the occurrence of phrynoderma, the condition has been strongly associated with multiple nutritional Zeder Psoriasis and is considered a sign of general malnutrition.
A rare case of esophagitis inflammation of the Zeder Psoriasis has recently been attributed to hyperkeratosis secondary to vitamin A deficiency read more Also, vitamin A deficiency affects iron Zeder Psoriasis, impairs hemoglobin synthesisand precipitates iron deficiency anemia that is only alleviated with supplementation of both vitamin A and iron see Nutrient interactions Vitamin A can be obtained from food as preformed vitamin A in animal products or as provitamin A carotenoids in fruit and vegetables see Food sources.
The most recent international standard of measure for vitamin A is retinol activity equivalents RAEwhich represent vitamin A activity as retinol. The Zeder Psoriasis for vitamin A was revised by the Food and Nutrition Board FNB of the US Zeder Psoriasis of Medicine IOM in Preterm infants are born with inadequate body stores of Zeder Psoriasis A, Psoriasis-Arthritis dimexide them at risk of developing diseases of the eye and the respiratory and gastrointestinal tracts.
About one-third of Zeder Psoriasis infants born between 22 and 28 weeks of gestation develop bronchopulmonary dysplasia BPDa chronic lung disease that can be fatal or result in life-long morbidities in survivors.
While vitamin A supplementation was included in some neonatal programs after this trial 60a national shortage in vitamin A supply that has affected US neonatal intensive care units since has led to a significant reduction in the use of vitamin A supplementation in premature newbornsg at birth with respiratory failure 61, However, a retrospective analysis of US nationwide Zeder Psoriasis from 6, preterm Zeder Psoriasis born between and found that a reduction in Psoriasis an den von A prophylaxis from In another retrospective study, the nonrandomized use of vitamin A supplementation with inhaled nitric oxide iNO was found to result in a lower incidence of BPD but not mortality compared to iNO therapy alone in Zeder Psoriasis newborns with a birth weight of g Neurodevelopment index scores at one year of age were also improved in the vitamin A group of newborns weighing g at birth.
Yet, caution is advised with the interpretation of the results, especially because the trial was erfunden Psoriasis designed to assess the effect of vitamin A. While high doses of vitamin A during early pregnancy can cause Zeder Psoriasis defects see Safetyvitamin A supplementation during late pregnancy may please click for source maternal and fetal Zeder Psoriasis A status Zeder Psoriasis a few randomized controlled trials have failed to show an effect on maternal and neonatal mortality 66more research is required to assess whether vitamin A supplementation during pregnancy reduces BPD incidence in infants.
However, vitamin A administration in this age group had no preventive effect on rates of pneumonia -specific mortality 7 studiesmeasles-specific mortality 5 studiesor meningitis-specific mortality 3 studies. Zeder Psoriasis, no reduction in the risk of disease-specific mortality Zeder Psoriasis found in neonates 0 to 28 days of age and infants 1 to 6 months of age supplemented with Zeder Psoriasis A Another meta-analysis of randomized controlled trials found no evidence of a reduction in mortality risk during infancy when either breast-feeding mothers 7 studies or infants aged less than six months 9 studies were supplemented with vitamin A Current WHO policy Zeder Psoriasis vitamin A supplementation at routine vaccination contacts in children after six months of age living in regions at high risk of vitamin Behandlung von Psoriasis Hautcreme König Bewertungen deficiency.
A recent placebo-controlled trial in Guinea-Bissau, which randomized Zeder Psoriasis, children ages, 6 to 23 months old to receive vitamin A supplementation at one vaccination contact, evaluated the co-administration of vitamin A and vaccines on child mortality The study found stationäre Phase Schuppenflechte vitamin A supplementation had no effect on overall mortality rates, although a six-month follow-up of infants given both measles and DTP diphtheria-tetanus-pertussis vaccinations showed a significant reduction in mortality in girls, but not in boys The recent pooled analysis of previous trials of vitamin A supplementation VITA I-III in Guinea-Bissau confirmed that vitamin A supplementation may interfere with vaccines.
Specifically, compared to placeboneonatal vitamin A supplementation was associated with a significant increase in mortality rates in boys but not in girls when children had received measles virus vaccination at 4. The timing of vitamin A interventions needs to be further examined in relation to the timing of Careers Psoriasis an den Ellenbogen erste Symptome ist in order to maximize their benefits.
An earlier meta-analysis of seven randomized controlled trials examining specifically the Zeder Psoriasis of vitamin A supplementation in 2, children with measles found Zeder Psoriasis overall reduction on the risk of mortality Similar to WHO and UNICEF guidelines, the American Academy of Pediatrics recommends vitamin A supplementation for children over six months of age when they are infected with measles while malnourished, Zeder Psoriasis, or are at risk of measles complications or vitamin A deficiency disorders Although measles infection has been associated with vitamin A deficiency and blindness, there is currently no evidence to suggest that vitamin A supplementation reduces the risk of blindness in children infected with measles Studies in cell culture and animal models have documented the Zeder Psoriasis for natural and synthetic retinoids to reduce carcinogenesis significantly in skin, breast, liver, colonprostateand other sites.
However, the results of human studies examining the relationship between the consumption of preformed vitamin A and cancer do not currently suggest that consuming vitamin A at intakes greater than the RDA benefit in the prevention of cancer 2.
A possible explanation for an increase in lung cancer is that the oxidative environment of the lung, created by smoke or asbestos exposure, could give rise to unusual carotenoid Zeder Psoriasis products, which might promote carcinogenesis At present, it seems unlikely that increased intake of preformed vitamin Zeder Psoriasis e.
Retinoids may be used at pharmacological doses to treat several conditions, including, acute promyelocytic leukemiaretinitis pigmentosa, and various skin diseases. Additionally, all of the retinoid compounds have been found to cause fetal deformations. Creme-Wachs für, women who have a chance of becoming pregnant should avoid treatment with these medications.
Retinoids tend to be very long acting: The retinoids discussed below are prescription drugs and should not be used without medical supervision.
Normal differentiation of myeloid stem cells in the bone marrow gives rise to plateletsred blood cells, and white blood cells also called leukocytes that are Zeder Psoriasis for Zeder Psoriasis immune response.
Altered differentiation of myeloid cells can result in the proliferation of immature white blood cells, giving rise to leukemia.
More information on APL treatment programs can be found in the National Cancer Institute website. Zeder Psoriasis natural and synthetic retinoids have been used as pharmacologic agents to treat disorders of the skin.
Acitretin is a synthetic retinoid that has been proven useful in combination treatments for psoriasis Topical tretinoin all- trans -retinoic acid and oral isotretinoin cis -retinoic acid have been used Zeder Psoriasis to treat mild-to-severe acne vulgaris 82, Retinoids exhibit anti-inflammatory properties and regulate the proliferation and differentiation of skin epithelial cells, as well as the production of sebum.
Use of pharmacological doses of retinoids especially oral isotretinoin by pregnant women causes birth defects and is therefore contraindicated prior to and during pregnancy see Safety in pregnancy. For more information on the use Zeder Psoriasis retinoids in the management of acne, see the article on Vitamin A and Skin Health. Retinitis pigmentosa Zeder Psoriasis affects approximately 1. RP describes a broad spectrum click at this page genetic disorders that result in the progressive loss of photoreceptor cells rods and cones in the retina of the eye Early symptoms of RP include impaired dark adaptation and night blindness, followed by the Zeder Psoriasis loss of peripheral and central vision over time Up to 12 years of follow-up in these patients did not reveal any signs of liver toxicity as a result of excess vitamin A intake Because neither Zeder Psoriasis younger than 18 Zeder Psoriasis nor adults affected by less common Zeder Psoriasis of RP were included in the trial, no formal Zeder Psoriasis about vitamins A and E could be made High-dose vitamin A supplementation to slow the course of RP requires medical supervision and must be discontinued if there is a possibility of pregnancy see Safety.
Free retinol is not generally found in food. Retinyl esters including retinyl palmitate are the storage form of Zeder Psoriasis in animals and thus the main precursors of retinol in food from animals. Plants contain carotenoidssome of which are precursors for vitamin A e.
Yellow- and orange-colored vegetables contain significant quantities of carotenoids. Green vegetables also contain carotenoids, though yellow-to-red pigments Zeder Psoriasis masked by the green pigment of chlorophyll 1.
The table below lists a number of good food sources of vitamin A, including fruit and vegetables, along with their vitamin A content. For information on this unit of measurement, see the section on RAE. In addition, use the USDA food composition Zeder Psoriasis to check foods for their content Zeder Psoriasis carotenoids without vitamin A activity, such as lycopene, lutein, and zeaxanthin.
Vitamin A Zeder Psoriasis currently listed on food and supplement labels in international units. The USDA database also provides the vitamin A content of food sources using the vitamin A international unit IU. Yet, contrary to RAE, the number of IUs of vitamin A does not reflect the bioavailability of vitamin A from different food sources. Thus, in Zeder Psoriasis 3the number of Zeder Psoriasis of vitamin A in carotenoid-containing food numbers in italics can be obtained by multiplying the RAE by approximately The principal forms of preformed vitamin A in supplements are retinyl palmitate and retinyl acetate.
The condition caused by vitamin A toxicity is called hypervitaminosis A. It is caused by overconsumption of preformed vitamin A, not Zeder Psoriasis. Preformed vitamin A is rapidly absorbed and slowly cleared from the body. Therefore, toxicity from preformed vitamin A may result acutely from high-dose exposure over a short period of time or chronically from a Zeder Psoriasis lower intake 2.
Acute vitamin A toxicity is relatively rare, and symptoms include nausea, headache, fatigue, loss of appetite, dizziness, dry skin, desquamation, and cerebral edema. Signs of chronic toxicity include dry itchy skin, desquamation, anorexia, weight loss, headache, cerebral edema, enlarged liver, enlarged spleen, anemiaand bone and joint pain. Also, symptoms of vitamin A toxicity in infants include bulging fontanels.
Severe cases of hypervitaminosis Zeder Psoriasis may result in liver damage, hemorrhageand coma. However, more research is necessary to Zeder Psoriasis if subclinical vitamin A toxicity is a Zeder Psoriasis in certain populations There is evidence that some populations may be more susceptible to toxicity at lower doses, including the elderly, chronic alcohol users, Zeder Psoriasis some people with a genetic predisposition to high cholesterol Although normal fetal development requires sufficient vitamin A intake, consumption of excess preformed vitamin A such as retinol during early pregnancy is known to cause birth defects.
In industrialized countries, pregnant or potentially pregnant women should monitor their intake of vitamin A from fortified food and food naturally high in preformed vitamin A e. The synthetic derivative of retinol, isotretinoin, is known to cause serious birth defects and should not be taken during pregnancy or if there is a possibility of becoming pregnant Tretinoin all- trans -retinoic acidanother retinol derivative, is prescribed as a topical preparation that is applied to the skin.
Although percutaneous absorption of topical tretinoin is minimal, its use during pregnancy is not recommended The recent meta-analysis of four prospective studies, including nearlyparticipants over 40 years of age, Zeder Psoriasis that highest vs.
Besides, the pooled analysis of four observational studies also indicated that a U-shaped relationship between circulating retinol and risk of hip fracture, suggesting that both elevated and reduced retinol concentrations in the blood were associated with an increased risk of hip fracture To date, limited experimental data have suggested that vitamin A as all- trans -retinoic acid may affect the development of bone-remodeling cells and stimulate bone matrix Zeder Psoriasis resorption reviewed in Vitamin A may also interfere with the Zeder Psoriasis of vitamin D to maintain calcium balance Chronic alcohol consumption results in depletion of liver stores of vitamin A and may contribute to alcohol-induced liver Zeder Psoriasis cirrhosis However, the Zeder Psoriasis toxicity of preformed vitamin A retinol is enhanced by chronic alcohol consumption, thus Zeder Psoriasis the therapeutic window Zeder Psoriasis vitamin A supplementation in alcoholics Whether wer und hat wie Psoriasis gewonnen increases the dietary requirement of vitamin A is not known.
Also, the use of cholesterol -lowering medications like cholestyramine and colestipolas well as orlistat, mineral oil, and the fat substitute, olestra, which interfere with fat absorption, may affect the absorption of fat-soluble vitamins, including vitamin A Further, intake of large doses of vitamin A may decrease the absorption of vitamin K.
Retinoids or retinoid analogsincluding acitretin, all- trans -retinoic acid, bexarotene, etretinate, and isotretinoin, should not be used in combination with single-nutrient vitamin A supplementsbecause they may increase the risk of vitamin A toxicity High potency vitamin A supplements should not be used without medical supervision due to the risk of toxicity.
Presently, there is little evidence that the requirement for vitamin A in older adults differs from that of younger adults. Additionally, vitamin A toxicity may occur at lower doses in older adults than in younger adults. As for all age groups, high potency Zeder Psoriasis A supplements should not be used without Zeder Psoriasis supervision Zeder Psoriasis to the risk of toxicity.
