Zinc is one of the most important trace elements in the body. It is involved in the work of over 300 enzymes and affects almost all systems. 🌿 Why is zinc needed? 1. Immunity Helps white blood cells fight viruses and bacteria. With a deficiency, frequent colds, long recovery. 2. Skin, hair, nails • Reduces inflammation → helps with acne • Improves wound healing • Strengthens nails • Reduces hair loss 3. Hormones and cycle • Important for progesterone synthesis • Can reduce PMS • Supports female fertility 4. Liver and detox Participant in enzymes that neutralize toxins. 5. Nervous system and energy Affects the production of neurotransmitters. 6. Thyroid hormones Without zinc, the thyroid gland works worse; fatigue, cold hands/feet may occur.

Food for me
Verified Purchase
I bought this for my own health to prevent illness and because I was worried about zinc deficiency. It's a zinc supplement with good content, easy to swallow, and has no strange taste. I'll have to observe the effects later.

I've been taking OptiZinc for about a month now, and so far my impressions are positive. I chose this particular form because OptiZinc is zinc monomethionine, which, according to research, is better absorbed and retained in the body longer than regular zinc sulfate or oxide. It's an excellent option for those looking for a bioavailable and effective form of zinc. It's suitable for supporting immunity, skin, and overall well-being. I'll be ordering again.

If I don't take it for a while, my physical condition definitely becomes unstable. I need zinc. When I take it for immunity, I make sure to space out the timing and also take copper. Balance is important. This zinc supplement contains a small amount of copper, but it's nowhere near enough.

The optimal form of zinc for maximum absorption and a large jar! The OptiZinc form (zinc monomethionine) is considered one of the best, as it is perfectly absorbed and does not cause any discomfort in the stomach. A huge package of 240 tablets is a mega-economical option for the whole family. An indispensable supplement for clear skin, fighting rashes and quickly supporting immunity.

essential trace element
Verified Purchase
participates in the work of over 300 enzymes in our body. If collagen is a "building material" and vitamin C is "cement", then zinc is the main manager who controls the processes of recovery and protection. It has been proven that Zinc activates T-lymphocytes. At the first signs of a cold, taking zinc can reduce the duration of the disease by 30-40%. Convenient to use, reliable packaging
