Excellent High-Potency Zinc for Immune and Fertility Support

A fantastic supplement. The 50mg dosage is high, so I find taking a capsule every two days is sufficient for my needs. It's excellent for immune function, and I also consider it a must-have for pre-pregnancy preparation for men, as zinc plays a key role in male reproductive health. The chelated form ensures great absorption without stomach issues. Very pleased.

High absorption with high dosage.

It's 50 mg so very useful if you have zinc deficiency. Highly absorbable because it's a chelated form. Overall great product if you need that much zinc.

I recently received my order from iHerb, and I’m very happy with the experience. The delivery was quick and reliable, and the packaging was neat and secure, so the product arrived in perfect condition. When I first opened it, I noticed a pleasant and natural aroma that immediately gave a good impression. The flavor/taste is also enjoyable and true to what I expected — it’s not artificial or overpowering. I also really appreciate the quantity; there’s plenty to use for a long time, which makes it feel like great value. Overall, from the fast shipping and secure packaging to the enjoyable aroma, taste, and generous quantity, I’m extremely satisfied. I will definitely order again and recommend this product to anyone looking for high-quality items from iHerb.

Knocks colds on their head

Whenever I feel a cold taking over I take this zinc for a few days and it almost always works to stave off the illness. I've tried other brands and doses of zinc, but this one is definitely the best I've used for immunity. And at a great price.

Better immunity and faster healing skin

I've been taking it every evening for a while now, and I've noticed that post-workout wounds and skin irritations heal faster. My colds have been less severe. The tablets are gentle on the stomach and don't cause nausea like regular zinc oxide. They're good, easily absorbed zinc

Effective

Right from the start, I could tell this product stood out from others I’ve tried. The presentation was neat, the instructions were easy to follow, and the quality felt trustworthy. I especially like how convenient the serving size is — not too much, not too little, just right. After using it daily, I noticed subtle but real changes: better balance throughout the day and a lighter, more energized feeling. It’s simple, effective, and exactly what I was hoping to find.
