Biotin and Zinc: What You Need to Know - Particle
Research shows that both biotin and zinc contribute to healthy hair and skin. A potent supplement can give your body a boost of these beneficial nutrients. A deficiency in vitamin C leads to scurvy, which is uncommon in the U.S. but can still occur in people with limited variety in their diet or people who smoke heavily. The RDA is 90 milligrams (mg) daily for men and 75 mg daily for women. A glass of orange juice provides 80 mg per serving. Vitamin C is found in many fruits and vegetables; the highest sources include bell peppers, citrus fruits and their juices. Biotin Although a relationship between vitamin D levels and AGA or TE is still being debated, most authors agree in supplementing vitamin D in patients with hair loss and vitamin D deficiency. Vitamin C intake is crucial in patients with hair loss associated with iron deficiency. There are no data to support the role of vitamin E in AGA or TE. Neural Regeneration Research: “High-dose biotin neither fosters remyelination nor stimulates malonyl coenzyme A synthesis in the regenerating nerve.” 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.”Three groups of molecules hydrolyze ATP, namely, ENTPDs, ectonucleotide pyrophosphatase/phosphodiesterases (ENPPs), and alkaline phosphatase (ALP) [ 33, 34]. The latter two molecules are zinc-dependent molecules. Among ENTPDs and ENPPs, ENTPD-1 (CD39), -2, -3, and -8 and ENPP-1, -2, and -3 hydrolyze ATP [ 33]. LCs strongly express ENTPD-1 (CD39) and weakly express ENTPD-2 and ENPP-1, -2, and -3. KCs weakly express CD39, ENTPD-2 and -3, and ENPP-1 and -2 [ 16]. Neither LCs nor KCs express ENTPD-8 or ALP. Therefore, although LCs strongly express CD39, other ATP-hydrolyzing molecules are weakly expressed in both LCs and KCs. LCs occupy approximately 3% of the epidermis, whereas KCs occupy approximately 97%. Regardless of this numeric difference between LCs and KCs in the epidermis, LCs perform approximately 80% of epidermal ATP hydrolysis, whereas KCs perform the remaining 20% [ 16]. Additionally, ZnD impairs the activity of ENPPs [ 35]. KCs weakly express ENPP-1 and ENPP-2. This explains one underlying mechanism by which ZD–KCs and BD–KCs show increased ATP production. Biotin is a water-soluble vitamin that serves as a co-enzyme for five carboxylases, namely, the covalently bound coenzyme for acetyl-CoA carboxylases 1 and 2, pyruvate carboxylase, propionyl-CoA carboxylase, and 3-methylcrotonyl-CoA carboxylase. These biotin-dependent carboxylases facilitate various metabolic reactions such as gluconeogenesis, fatty acid synthesis, and amino acid synthesis. Mammals cannot synthesize biotin by themselves; they obtain biotin through food and some gut microbiota produce biotin. Biotin deficiency (BnD) rarely occurs in people who consume a normal mixed diet [ 1, 2]. However, genetic deficiency of holocarboxylase synthetase and biotinidase, continuous consumption of raw egg whites, parenteral nutrition, and modified milk without biotin supplementation could result in BnD [ 1, 2, 3]. Patients with BnD [ 4] are known to develop clinical symptoms that are similar to those in patients with acrodermatitis enteropathica (AE), which is caused by loss-of-function mutations in Zrt-, Irt-like protein (ZIP) 4 [ 5, 6, 7]. The clinical symptoms of AE include characteristic skin lesions, alopecia, and diarrhea.

BnD causes abnormalities in the fatty acid composition of skin, such as accumulation of odd-chain fatty acids and abnormal metabolism of long-chain polyunsaturated fatty acids [ 4, 23, 24]. In this study, we found that dietary BnD leads to ZnD. However, the decline in the serum zinc levels in BD mice was relatively slower than that in ZD mice [ 8]. Accordingly, although changes in terms of the body weight and survival rate were similar to those observed in ZD mice, the kinetics in BD mice was slower than that in ZD mice [ 8]. LCs were found to be almost absent in the epidermis of BD mice, thereby leading to enhanced ATP production in skin, and similar findings were observed for ZD mice. This aberrant ATP accumulation in the skin results in the recruitment of neutrophils [ 25] and development of characteristic skin lesions in patients with ZnD and BnD. Indeed, decreased serum zinc levels have been reported in some patients with BnD [ 26, 27, 28]. On the other hand, some studies have demonstrated normal serum zinc levels in patients with BnD [ 29, 30, 31]. We speculate that this discrepancy might be attributable for the duration of BnD. Reduced serum biotin and zinc levels have been recently reported in patients with male androgenetic alopecia, suggesting the close association between biotin and zinc [ 32]. We investigated how dietary BnD led to ZnD but the precise mechanisms could not be elucidated (data not shown). Further analysis is required for elucidating the underlying mechanisms. Iron deficiency is common in females with hair loss, and most authors agree in supplementing iron in patients with iron deficiency and/or low ferritin levels. However, there is no consensus on “normal ferritin” levels, and most authors prescribe supplements to the patient when the ferritin level is < 40ng/dL. l-lysine supplementation is recommended for vegan individuals with iron deficiency. If you're trying to grow your hair fast, you've probably heard about biotin. An over-the-counter vitamin that's used in everything from hair, skin and nails tablets to biotin-rich shampoos, it's one of the most searched for supplements out there.
Biotin Deficiency - StatPearls - NCBI Bookshelf
If you want to make sure you’re getting enough biotin, the daily recommended biotin intake is 30 micrograms (mcg) for adults, according to the National Institute of Health. If you’re pregnant, you need about 35 mcg a day. Biotinidase deficiency confirmation is done by DNA analysis, either allele-targeted methods or full-gene sequencing. Currently, all newborn screening programs in the U.S. and more than 30 other countries carry out screening for biotinidase deficiency. [6] [7] [30] [7]The word “biotin” comes from the Greek word “biotos.” It means “sustenance” or “life.” Biotin is a crucial nutrient for good health. 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]. Milk. One cup of 2% milk has 0.3 micrograms of biotin. Milk also contributes to bone and teeth health, and it is a good source of protein, calcium , phosphorous, potassium, and vitamin D. Vitamin B7 (biotin or vitamin H) is a cofactor for five carboxylases that catalyze steps in fatty acid, glucose, and amino acid metabolism. Biotin also plays roles in histone modification, cell signaling, and gene regulation [ 25]. Most dietary biotin is found in protein. Dietary protein must be broken down into free biotin, which is then stored in the small intestine and liver. An adequate intake of biotin for adults is 30 mcg/day in U.S. populations. The average dietary intake of biotin in Western countries is adequate, and biotin deficiency is rare. Severe biotin deficiency in healthy individuals eating a normal diet has never been reported [ 26, 27]. While there is no upper limit for biotin intake—as there is no evidence for biotin toxicity—high biotin intake can cause falsely high or falsely low laboratory test results [ 28]. Many supplements for hair, skin, and nails far exceed the recommended daily intake of biotin [ 28].

Vitamin C, or ascorbic acid, is a water-soluble vitamin derived from glucose metabolism. It is a potent antioxidant preventing the oxidation of low-density lipoproteins and free radicals damage. It also acts as a reducing mediator necessary for collagen fiber synthesis through hydroxylation of lysine and proline. Vitamin C plays an essential role in the intestinal absorption of iron due to its chelating and reducing effect, assisting iron mobilization and intestinal absorption [ 50]. Therefore, vitamin C intake is important in patients with hair loss associated with iron deficiency. Biotin also regulates immunological and inflammatory functions. Patients with multiple carboxylase deficiency, which has links with biotin deficiency, have shown defects in B-cell and T-cell immunity. Biotin plays a key role in the function of natural killer (NK) lymphocytes and the generation of cytotoxic T lymphocytes. It shows a role in the maturation and responsiveness of immune cells. Evidence shows increasing interleukin-1-beta (IL-1-beta) and proinflammatory cytokines TNF-alpha in biotin deficiency. Biotin levels also affect transcriptional factors, such as NF-kappa B.

There are a couple different ways to reap the benefits of biotin. Believe it or not, you may be already getting a decent dose without knowing it. Biotin is thought to help nerves recover from damage, especially in people with progressive diseases, such as multiple sclerosis. However, recent studies don't show any long-term benefits of taking high doses of biotin for nerve health. Foods With BiotinBesides iron, zinc is the most common element in the body. The role of zincin the body is vital. Every body cell needs zinc to perform normal chemical reactions. In addition to the role biotin plays as a cofactor in various carboxylation reactions, recently, it has been observed that biotin plays important roles in gene expression and immune mechanisms.
