  2. Now Foods, Biotin, 5,000 mcg, 120 Vcaps. Source:

Another great source is Swanson’s health products.


Biotin can be obtained through diet or supplementation. Biotin is a water-soluble B vitamin (B-7) typically found in liver, egg yolk, cereals, legumes and nuts. In the body, biotin is found in low concentrations in the brain, liver and muscle tissues. Biotin is essential for normal growth and body function. Biotin is a key regulatory element in gluconeogenesis, fatty acid synthesis, and in the metabolism of some amino acids, and energy production (ATP). Alcohol consumption decreases biotin status in the body.

Alongside its role in energy production, Biotin enhances the synthesis of certain proteins. In addition, Biotin promotes normal immunity and plays a critical role in skin health.

In summary Biotin is used because it:

  • Supports healthy skin through proper fat production
  • Supports making efficient use of sugar (required to turn sugar into energy)
  • Maintains an energy supply in nerve cells
  • Promotes normal immunity
  • Supports the nervous system
  • Supports cell growth
  • Supports energy production
  • Supports the production of fatty acids
  • Supports the metabolism of fats and amino acids
  • Supports maintaining a steady blood sugar level
  • Supports Nails, Hair and Skin (scalp)

I started taking this to help with thinning hair. I can say my hair is definitely feeling and looking better, so I’ll stick with it a couple more months to see.

Review December 06, 2008
From Washington
I love this product. The reason I ordered two, instead of one, is because I recommended it to a friend and she couldn’t afford it, so I bought her some. I have been using it for a number of years, and it has really made a difference. I have recommended it to many people who are still using it. I am 55 years old and for years my hair would just get to a certain length and stop. Since I have been using this product, my hair grows like crazy and is much healthier. Thank you so much!!

Country Life, Biotin, 5 mg November 17, 2009

Great product, my hair and nails grow faster when I take this and MSM together. Small capsules make swallowing easier. Great price. I have learned to purchase all my supplements together to save on shipping and get a discount as well. Thanks Iherb for great and super fast service!

Biotin 5mg July 18, 2009
Recommended for hair thinning. It takes 3 – 6 months to see results . In the 3 weeks that I have taken it I have comments that my hair is looking healthy. Someone close even ask me what I was using. I also take it for my nails. No nail results yet. So now I wait.

Works for me! January 22, 2008
From Washington
I use these for burning in my toes and for the feeling of pins and needles in same.

Blood glucose regulator March 04, 2008
From New York
It does an excellent job of regulating blood glucose levels. As a former diabetic, it was very important to keep your fasting blood levels within optimal range. Biotin, along with a sensible diet and exercise did just that. Great product. I urge anyone with type 2 diabetes to try it.

By Allie Lewis From Georgia
I have used several other brands of biotin trying to be cost effective. I came back to Jarrow because I can SEE the difference it makes in my hair and nails. I won’t waste my money anymore buying others.

Joan March 21, 2008
By Joan LaFontaine From Florida
Having had some difficult hair and nail problems, my dermatologist recommended 5mgs of Biotin — and the benefits have been nothing less than amazing.

great for growing beautiful hair November 09, 2007
From Connecticut
i bought this per a reccomendation by a hairstylists’ naturopath to take 5mg of biotin a day to grow my hair quicker and more healthy and full, so far so good! it’s a water soluble vitamin, so it seems unlikely there would be any chance of any harmful effects from an overdose.

Helped my Hair July 25, 2008
From Australia
I have suffered from excessive hair shedding particularly summers for some years so tried liquid silica along with my other supplements for a few months last year with no change until adding this Biotin, after which I noticed a significant difference. Right through summer I was amazed. Have read in some cases of it being attributed to increased acne but worth a try in case lacking in Biotin and/or excessive hair shedding. Still working on improving hair condition and sheen so will be trying MSM as well.

The right price January 14, 2007
This product shows improvement within weeks of use

Superb! December 08, 2008
