This is one of my favorite brand of vitamins recommended by my doctor Who uses them himself. They are the best quality, most pure with the least amount of fillers and unnecessary ingredients.My husband and I use these every day!

Great brand!

I started taking this vitamin C to help absorb iron and it works great. My energy level is a lot better throughout the day. Easy to swallow. Also good for balancing out hormones along with other supplements.

while i was taking this. i was never sick. A little while after i ran out of them. approx. a week. i got sick. and i’m still sick. i learned my lesson never to let it lapse

I use this brand most exclusively. They are a clean product.
