Includes a variety of vegetables; fruits; grains (at least half whole grains); fat-free and low-fat milk, yogurt, and cheese; and oils. For horses in shoes or barefoot, minerals are essential for healthy hooves. A mineral balanced diet with adequate levels of calcium, zinc, copper and selenium is a must. High dietary and/or water levels of iron, manganese or sulphate can interfere with copper and zinc absorption. Biscolla RPM, Chiamolera MI, Kanashiro I, Maciel RMB, Vieira JGH. A single 10 mg oral dose of biotin interferes with thyroid function tests. Thyroid 2017;27:1099-1100. [ PubMed abstract] For one, biotin supplementation can falsely lower thyroid-stimulating hormone (TSH) in lab tests. Dr. Fossati warns that this “can make it harder to accurately diagnose hypothyroidism,” which is when you don’t have enough thyroid hormones, or can lead to a mistaken hyperthyroidism (when you have too much thyroid hormone) diagnosis.

Reilly, D.F. Cottrell, R.J., Martin and D.J. Cuddeford looked at the impact of feeding biotin at a rate of 0.12 mg/kg of body weight to evaluate the growth and growth rate of the hooves with 8 match-paired ponies. The outermost layer of the hoof contains a variety of fats and waxes. When present in the correct amounts, in an unbroken layer, this seals the internal moisture into the hoof structure and seal water out. Essential Omega 3 fat found in micronised linseed is essential for improved hoof quality.As well as helping to maintain healthy hair, Biotin has also been proven to contribute to normal skin and nails. High strength small form tablet John J, Lipner S. Consumer perception of biotin supplementation. J Cutan Med Surg. 2019 Dec;23(6):613-616. doi:10.1177/1203475419871046 Pure Encapsulations is a trusted supplement brand among healthcare professionals. The ingredients and products undergo rigorous testing by a number of third-party labs, such as Silliker, Eurofins, Covance, and Advance Laboratories. Supplement type. As with any supplement, you’ll want to choose the form — softgel, gummy, or liquid — that’s easiest and most convenient for you to take.

At the start and end of the study, digital images were taken of the affected areas on the scalp. Each participant’s hair was also washed and any shed hairs were counted. Researchers found that women who took an MPS experienced a significant amount of hair growth in the areas affected by hair loss and less shedding. The FNB was unable to establish ULs for biotin because there is no evidence in humans that biotin is toxic at high intakes [ 1]. Several studies have found no adverse effects of 10–50 mg/day biotin, and up to 200 mg/day oral biotin or 20 mg/day intravenously in patients with biotinidase deficiency do not produce symptoms of toxicity [ 1, 10]. Keep in mind that there’s little evidence to support the use of biotin for hair, nail, or skin health. Consuming a healthy, well-rounded diet will do much more for your hair, skin, and nails than taking a supplement. Li D, Radulescu A, Shrestha RT, Root M, Karger AB, Killeen AA, et al. Association of biotin ingestion with performance of hormone and nonhormone assays in healthy adults. JAMA 2017;318:1150-60. [ PubMed abstract] For more on the Vitamin B family and what these vitamins do for the body, ‘What’s the best Vitamin B to take?’) How do you take biotin?There is no current ‘recommended’ intake for biotin like there is for many other vitamins like vitamin C and vitamin D, as more research is needed. Great product! Very tasty and I look forward to them every morning. I feel so much more energised and my hair is shinier.”

My friend recommended these gummies as my hair has been thinning due to the menopause. I have used for the last three months and have been impressed by the results. My hair definitely has more body and is looking healthy and strong. Would definitely recommend.”While being deficient in biotin is considered to be rare, it can sometimes result in hair loss that can possibly be helped by taking biotin supplements. Again, make sure you speak to your GP first before taking biotin supplements. What are the side effects of biotin? Perry CA, West AA, Gayle A, Lucas LK, Yan J, Jiang X, et al. Pregnancy and lactation alter biomarkers of biotin metabolism in women consuming a controlled diet. J Nutr 2014;144:1977-84. [ PubMed abstract] Elston MS, Sehgal S, Du Toit S, Yarndley T, Conaglen JV. Factitious Graves' disease due to biotin immunoassay interference‒acase and review of the literature. J Clin EndocrinolMetab 2016;101:3251-5. [ PubMed abstract] It’s also worth noting that if you have ‘extra’ biotin in your body, it will naturally be flushed out of your system when you urinate. It’s possible to get all the biotin you need, simply by eating a healthy, balanced diet, as there’s a wide range of biotin-rich food out there (the examples above are literally the tip of the iceberg). Biotin deficiencies are rare and it’s impossible to have too much of it in your system because your body naturally gets rid of an excess biotin when you urinate.

This is a fact sheet intended for health professionals. For a general overview of Biotin, see our consumer fact sheet on Biotin. Introduction At least a third of pregnant women develop marginal biotin deficiency in spite of normal biotin intakes; plasma and breastmilk concentrations of biotin decrease in lactating women, even when their dietary biotin intakes exceed the AI [ 2, 18, 22]. Additional research is needed to understand the clinical significance of these findings. Biotin and Health Hair, nail, and skin health Shelley WB, Shelley ED. Uncombable hair syndrome: observations on response to biotin and occurrence in siblings with ectodermal dysplasia. J Am Acad Dermatol 1985;13:97-102. [ PubMed abstract] The nutritional supplement treated animals had a 15% higher growth rate of the hoof horn and 15% more growth of hooves at the midline dead-centre after 5 months of biotin supplementation compared to the control ponies. Will biotin support hoof health?

Although there are no nationally representative estimates of biotin intakes in the United States, the average biotin intake from foods in other western populations is about 35–70 mcg/day, indicating that most people in these countries consume adequate amounts of biotin [ 2, 3].
