Biotin for Back Hair Growth

Biotin is one of the key hairfinity ingredients. On reviewing the full list of ingredients, from the volume of Biotin I think we can assume that it plays a vital role to hair growth.

Did you know biotin is another name for Vitamin H? Many of us know about the main ‘vitamin letters’ like A, B, C, D E, but yep there’s an H! The H is said to stand for the German words for hair and skin – Haar and Haut. To confuse you a bit, biotin is also referred to as coenzyme R and vitamin B7. Hmmm, maybe the scientists didn’t like the letter H. Well vitamin B7 aka, coenzyme R, aka biotin is a key member of the B complex vitamins. It took over 40 years for biotin to be considered a vitamin! Within the years of scientific research it was found that all living organisms require biotin but it can only be made by some plants, algae, mold, yeast, algae or bacteria.

Good ol Wikipedia notes that, “Biotin is necessary for cell growth, the production of fatty acids, and the metabolism of fats and amino acids. Biotin assists in various metabolic reactions involving the transfer of carbon dioxide. It may also be helpful in maintaining a steady blood sugar level. Biotin is often recommended as a dietary supplement for strengthening hair and nails, though scientific data supporting this outcome are weak”

Many foods are rich sources of biotin; from peanuts to avocado.

Interestingly in 1998 the Food and Nutrition Board of the Institute of Medicine saw sufficient need to establish a RDA for biotin and issued the below ‘Adequate Intake – AI’ amounts.

Look back at the list of hairfinity ingredients. What do you notice? The AI for adults is 30 mcg daily and harfinity is shootings us with 2500 mcg. Manetabolism took another step by loading 5000 mcg into their formula. So what’s with this? I’m sure most people are wondering if this is safe. I am not. 😉 It was once explained that the human body will take the vitamins it needs and expel any excess in urine. I’m ok with that if the extra biotin boost with supercharge hair growth. Why would these formulas rely so much on biotin if the research was ‘weak’? I will aim to understand why biotin is the supercharged member of the hairfinity ingredients and either update this post or add another.
