Gentle and Effective Zinc Supplement
I’ve been taking Natural Factors Zinc Bisglycinate for a few weeks now, and I’m really happy with it. The chelated form (bisglycinate) is supposed to be more easily absorbed and gentle on the stomach, and I’ve definitely noticed that—I can take it even without food and it doesn’t upset my stomach at all.
I take it to support my skin, immune system, and hormonal balance, and I’ve already seen small improvements, especially in terms of fewer breakouts. The capsule is a good size and easy to swallow. I also appreciate that it’s a clean product without unnecessary fillers. Will definitely keep this in my supplement routine.

The chelate bond ensures that zinc is better absorbed into the body without being blocked by food. I add copper chelate every few hours

One of my basics for immunity
What can I say, I have been taking zinc regularly since pandemic days (among other daily immune boosters eg Vit C), and my immunity seems great. Not even a cold in the last 5 years. Of course there are other factors involved, but for what it’s worth my one Covid infection was extremely mild and lasted 2 days!
Taking zinc regularly improved the healing time for little wounds and scratches.

High-quality zinc, gentle on the stomach
This form of zinc is very well tolerated — no nausea or discomfort like with other types. I take it after meals, and it absorbs beautifully. Great for supporting the immune system, skin health, and overall energy levels. I noticed fewer colds and faster recovery after workouts. Clean formula, vegetarian capsules, and a trusted brand. Definitely a staple in my supplement routine!

Best form of Zinc, a very trustworthy brand if you want the best in bioavailability in your vitamins. No stomach or gastric issues - NECESSARY if you have Type 2 Diabetes and/ or ADHD. Remember to grab some chelated Zinc with this! You can't absorb it otherwise - only 2.5mg chelated copper needed for 50mg of Zinc!
