Biotin is great for hair and nails.
Swanson Vitamins is the place to go for inexpensive, high quality supplements.
They have a huge selection of products and even have a lot of single ingredient items. I even can find stuff there I can take and I react to almost everything.
I recently got a double order of Zinc (my latest order) and some D3. I’ve still got a couple of Biotin, have gone through 1/2 a bottle so far over the months.
Thanks for the note.
