Great for Sports

Zinc Bisglycinate Chelate - the best form of zinc. 15 mg - a good dosage, not too little, not too much. A nutritionist prescribed it for my son of 12 y.o. who is swimming in a squad five times a week early in the morning for two hours. Dr Mercola is considered to be one of the best in the market. Indeed, my son is doing well and not have sicknesses. Small size of capsules. No taste, no smell.

maybe the best there is

Verified purchase

it has copper which is absolutely necessary for zinc to work as it should (Essential Synergy) , I hate the smell ,so it's better to take it with some food (don't take it with iron/calcium rich food like dairy)

It's a great supplement in terms of composition, but I'm confused that it always gave me heartburn. Tested for use on an empty stomach, with and after food. I left the packaging to a friend, and she was O.K.

You need to take it for at least 2 months, at least, and in full 4-6 months, but the result is 9 out of 10 points

High-Quality Immune Support & Excellent iHerb Service

Verified purchase

This is an excellent supplement for anyone looking to bolster their immune system. The formulation of Dr. Mercola's Zinc Plus Selenium is well-balanced, and I appreciate that it includes copper, which is essential for proper zinc absorption and balance. The capsules are easy to take, and I feel confident in the quality of the ingredients. It's a key part of my daily wellness routine. I also want to mention the great experience I had purchasing from iHerb. Their mobile application is easy to navigate, I found exactly what I needed, and the delivery was incredibly fast and efficient. It's a reliable company that I trust for my supplement needs.
