I thought that by taking OptiZinc I would be getting the best and most absorbable type of zinc for my family. I just found out that there are two different kinds of OptiZinc. The L-form is natural. The D-form is synthetic. It's what they put in animal feed. It doesn't absorb as well and have the same benefits. I figured out that it was making my heart and mind race when I took it. If you want the highest quality OptiZinc, look for L-OptiZinc. If it doesn't have the L in front, it is the D form.

This product is amazing. I have been taking it for about 4 months daily. I went to the eye doctor today. My prescription has gotten better. It’s back to what it was in 2011.

I have used this along with selenium and have seen my vision noticeably improved.

I’ve used this product for years now and it has Helped me with my acne. When I’m consistent with one pill a day (30mg), my skin seems clearer and no active acne presents itself.

I bought this product thinking it just contained Zinc, to help treat cystic acne. However, once the whole bottle was almost gone, I discovered that it also includes kelp, which caused a severe cystic acne breakout. This supplement also includes B6, which can also lead to acne breakouts in some. I don't feel the name of the product makes it clear that the product includes key ingredients other than Zinc. I deeply regret this purchase. I had purchased the Source Naturals brand in the past, and erroneously thought this product was comparable . . . big mistake.

The best Zinc supplement. ive tried a few but I feel this one is very absorbent for body. I sometimes take 2 or 3 caps a day when I feel a cold coming on. I trust Solaray brand.
