Salmon. A 3-ounce serving of cooked salmon has 5 micrograms of biotin, about 17% of your daily value. Published data on AA suggest that vitamin D, due to its immunomodulatory effect, may be involved in AA [ 66, 67]. Lee et al. conducted a systematic review and meta-analysis of observational studies on the prevalence of vitamin D deficiency and/or serum vitamin D levels and AA [ 68]. These authors analyzed a total of 14 studies that involved 1255 patients with AA and 784 control patients without AA. The mean serum 25-hydroxyvitamin D [25(OH)D] level in patients with AA was significantly lower than that in the non-AA control group, by 8.52ng/dL (95% confidence interval −11.53 to −5.50ng/dL). Vitamin D deficiency was also highly prevalent in patients with AA, leading the authors to suggest that the vitamin D level has to be measured in patients with AA. These results also suggest that vitamin D supplements or topical vitamin D analogues should be considered for patients with AA and vitamin D deficiency. However, the meta-analysis did not find any clear correlations between extent of hair loss and serum 25-hydroxyvitamin D level [ 68]. Having 10mg or less a day of copper is unlikely to cause any harm. This includes copper from food, water and supplements. Magnesium Test material. Subjects were randomized in double-blind fashion to receive the new oral supplement (Viviscal ® Maximum Strength) or placebo. Viviscal contains AminoMar C ™ marine complex, a proprietary blend of shark and mollusk powder, an organic form of silica derived from Equisetum sp. (horsetail), vitamin C derived from Malpighia emarginata (acerola cherry), microcrystalline cellulose (E460), natural orange flavor, magnesium stearate, hypromellose, and glycerol. Placebo treatment consisted of inert tablets with similar appearance. Subjects were instructed to take one tablet of their assigned treatment each morning and one tablet each evening with water following a meal.
Processing nutrients from food –biotin supports the enzymes responsible for breaking down the fats, proteins and carbs from our food. Because vitamin A is stored in our bodies, excessive quantities can be toxic, so be careful to not overdo vitamin A intake. The recommended daily allowance (RDA) is 900 micrograms daily for men and 700 micrograms daily for women. About one cup of raw carrots provides 900 mcg. To maximize your vitamin A potential, eat a well-rounded diet and include plenty of fruits and vegetables, along with dairy products, fish, liver, and fortified cereals. Vitamin C You should be able to get all the molybdenum you need by eating a varied and balanced diet. The molybdenum we get from food is not likely to be harmful. Phosphorus Taking a supplement is an easy and convenient way to get your daily dose (we need it every day as it is water-soluble There's some evidence to suggest taking molybdenum supplements might cause joint pain. What does the Department of Health and Social Care advise?If you’re dealing with hair loss, you’re likely wondering not only what you can do about it, but also why it’s happening in the first place. Hair loss has multiple causes, many of which are systemic. “If your hair is falling out at the roots, often something is going wrong in your body or in your life situation,” Dr. Bergfeld says. While signs of biotin deficiency include hair loss, skin rashes, and brittle nails, the efficacy of biotin in supplements for hair, skin, and nails as a means to remedy these conditions is not supported in large-scale studies [ 25, 26]. In fact, only case reports have been used to justify the use of biotin supplements for hair growth. These case reports were in children and found that 3–5mg biotin daily could improve hair health after 3–4months in children with uncombable hair syndrome [ 37, 38]. As a result, it’s important to talk with a healthcare professional before taking a biotin supplement. Majeed M, et al. (2020). Clinical study to evaluate the efficacy and safety of a hair serum product in healthy adult male and female volunteers with hair fall.
In 2008, Du et al. [ 115] described the role of hepcidin in iron regulation and hair loss in the ‘mask mouse,’ which was reversed with iron supplementation [ 85]. Hepcidin is a liver-derived protein that restricts enteric iron absorption; this protein is considered the iron-regulating hormone found in all mammals and to be responsible for iron uptake. Several proteins stimulate the expression of the gene encoding hepcidin ( HAMP) in response to high levels of iron or infection. However, the mechanism of HAMP suppression during iron depletion is not well understood. Du et al. reported the loss of body hair and development of iron deficiency anemia in the ‘mask mouse’ as a result of a mutation in the TMPRSS6 gene. The protein encoded by TMPRSS6 (matriptase-2) was found to negatively regulate the HAMP gene. In mice, a mutation in TMPRSS6 was associated with failure to downregulate the expression of HAMP and was associated with increased levels of the hepcidin, reduced absorption of dietary iron, and, consequently, iron deficiency. Interestingly, iron supplementation in these mice reversed the iron deficiency and induced hair growth [ 115]. Antioxidant-rich –it is believed that zinc contains antioxidant properties which could help protect our cells from oxidative damage. 3 Study results are conflicting, but most authors agree on supplementing vitamin D in patients with hair loss and vitamin D deficiency Frontiers in Nutrition: “Influence of biotin intervention on glycemic control and lipid profile in patients with type 2 diabetes mellitus: A systematic review and meta-analysis." In fact, biotin is primarily used for alopecia — a condition that causes hair loss in all sexes. “Biotin helps maintain hair growth and helps with inflammation,” Dr. Bergfeld says. “The hair follicle, the skin and the nails all benefit.”Adults should eat no more than 6g of salt a day – that's around 1 teaspoon. On average, we eat 2.1g more salt than we should each day. That’s why some people choose to take biotin supplements; think of them as a little insurance in the same way as multivitamins are. High dosage A review article on zinc in patients with AA showed that four of the six case–control studies found low zinc levels in patients with AA as compared to healthy control groups [ 55]. One of these case–control studies was conducted by Kil et al. and included patients with MPHL, FPHL, and TE. The results of this study showed a strong correlation between zinc deficiency (< 70µg/dL) and hair loss [ 124]. Another study found a strong association between zinc deficiency and AA severity and chronicity [ 126]. However, in contrast to these studies, there are two case–control studies carried out in Iran [ 111] and Finland [ 113] that showed no significant correlation between zinc level and AA compared to the controls.

Cordova E, et al. (2016). Possible drug–herb interaction between herbal supplement containing horsetail (equisetum arvense) and antiretroviral drugs: Report of 2 cases. Several clinical studies have implicated oxidant/antioxidant discrepancy in patients with AA, which is a disease dependent on autoimmunity, genetic predisposition, and emotional and environmental stress. These studies have been reviewed, with most reviewers reporting increased levels of oxidative stress biomarkers and decreased levels of protective antioxidant enzymes in patients with AA [ 79]. Hair loss is a common problem that may be improved with vitamin and mineral supplementation. Vitamins and minerals are important for normal cell growth and function and may contribute to hair loss when they are deficient. While supplementation is relatively affordable and easily accessible, it is important to know which vitamins and minerals are helpful in treating hair loss. Other natural products, such as biotin and zinc, have also been advocated for the treatment of hair loss. Biotin is a water-soluble vitamin and an essential coenzyme for several important enzymes 15 while zinc is an essential micronutrient that is responsible for the normal functioning of hundreds of enzymes. 16 , 17 The use of these agents for hair loss is based on the observation that alopecia is one of many consequences associated with biotin 15 and zinc deficiencies. 18 In one case report, a child with alopecia due to zinc deficiency was administered a zinc supplement and her hair loss stopped in three weeks 18; however, the use of a zinc supplement in a group of 15 patients with alopecia areata and low serum zinc levels did not result in significant hair growth. 19 A literature search did not reveal any studies describing the use of biotin supplementation for the treatment of hair loss. Biotin supplements are often marketed as having benefits for hair, skin, and fingernails. If you have a shortage of biotin in your diet, you could have thinning hair, or skin or nail problems. But there's little scientific evidence that supplements can improve hair, skin, or nail health in people who don't have a biotin deficiency.Passi et al. noticed a significant deficiency of serum vitamin E in patients with seborrheic dermatitis (both human immunodeficiency virus [HIV] seropositive or HIV seronegative) ( p<0.001) as compared with a control group [ 129]. Of note, zinc therapy was found to significantly increase both the size of the sebaceous glands and cell proliferation in the sebaceous glands in an animal study [ 130]. vi.
