SAVED MY HAIR!!!

I've been taking these Biotin capsules from Sam's for more than 4 years; the best value I've found anywhere and I truly believe it has saved my hair. I've been taking chemo for more than 12 years & will need to continue the rest of my life. I am so Thankful for this product.

Best Biotin out there for the money...

I have been taking MM Biotin for a year or two now and it helps. I have thinning hair and nails because of my thyroid. This is a great supplement and far less expensive than anywhere else.

Member's Mark Biotin 10,000 mcg With Keratin

First time user for this higher dose of Biotin. Tolerating it well. Good price for this product. Still determining benefit of going from 5000 mcg to 10,000 mcg product.

Love it

I have been taking the pills for about six months. At first I didn’t see any hair growth. Now my hair has grown so thick and long. It takes awhile but in the end it will be worth it.

Biotin supplement

My doctor advised me to start taking this to help my body recover from hormone problems. This was the best price from all over, good quality. Thank you Sam's!

Love it.

My hair had thinned a great deal prior to taking this vitamin. Now approximately a year later I have regained most of my hair. I can wear ponytails without bald spots.

Strong and Long Hair

I have noticed more new growth in my hair after using the MM Biotin. My hair is stronger with less shedding.

Excellent formula that improves hair, nails

This is the best hair and nail formula i have ever used. I preferred them, but sams didnt carry them for a while. I used several others but didn't see results after months. The gummies just gave me 2 cavities. I never et cavities. I wa so happy these were back.

Some of Biotin capsules were empty.

Some of the capsules were empty. The bottle was sealed and did not appear to have been tampered with. Most of the capsules look okay, but some have very little biotin in them. I hope this not a trend toward lower quality. Just seems strange! I'm not even sure that anyone reads the comments, as I have never had a response to a comment.
