Absorbable

This type of zinc was recommended by Dr. Eric Berg. It's more easily absorbed than other types of zinc. Thorne is a trusted brand that is known as high quality.

Inconsistently Filled, Terrible Nausea

I've been through 4 bottles now and each one has contained caps that are half filled or even mostly empty in a few cases. That's quite concerning as I'd expect quality controls to prevent this happening regularly. That issue alone is enough to make me switch. Additionally, this particular supplement makes me extremely nauseous and has even cause me to vomit. I've not experienced that with other Zinc supplements.

Excellent Zinc Supplement!

All Thorne products are excellent and this Zinc Bisglycinate is good too. I purchased this form of zinc as it is highly absorbable like zinc picolinate. I alternate between the the two. I also got my parents taking it to strengthen their immune system.

Ideal Zinc supplement

No flavor. This is the ideal form to supplement per the literature. Great Brand and value. Don’t forget your daily Vitamin D3 supplement as well if you live north of Tennessee! Together these are strong immunity boosters.

Great product and easy to swallow

My recent order didn’t actually make it to my home due to a shipping error, however, we have used this product and other Thorne products over the last 15 years and been very happy with them.
