iHerb Customer Reviews
L-OptiZinc ► The Only High Potency Zinc Supplement FDA Approved Safe For Human Nutrition
L-OptiZinc is the only high-potency zinc supplement FDA approved safe for human nutrition. L-OptiZinc is also an approved form of zinc for use in the EU in food supplements. In general, zinc is an essential mineral involved in regulating a large amount of enzymes in the body. It is known as an antioxidant and immune boosting supplement, and is most commonly supplemented to reduce the frequency of sickness and to support optimal testosterone levels. Zinc is highly involved in many enzyme systems in the body. Keeping normal zinc levels helps with the maintenance of these enzyme systems and acts as a hormonal and immune system aid. High dose zinc in response to the common cold (not taken preventatively, but only at the onset of sickness) appears to be effective in reducing the duration and severity of sickness. Zinc is also known to be circulating at lower levels in persons with acne relative to those without, and it is thought to be therapeutic by reducing the migration of immune cells to the skin and possibly reducing the effects of androgens on the skin. A number of trials using zinc for acne control note that standard to high supplemental dosages have a modest protective effect. L-OptiZinc is a forms of methionine-bound zinc that increase the bioavailability of zinc. Methionine is the amino acid best absorbed by the body. L-OptiZinc is standardized to 20% zinc, consists of zinc bound to the more bioavailable "L" form of methionine. Some preclinical studies show that L-OptiZinc is absorbed better, retained longer and are more effective than other zinc supplements tested. Taking everything into account, I highly recommend this high quality product manufactured by Now Foods with reasonable price offered by iHerb. A single dose per day is what you need. I hope you'll find my review helpful to you. I am a strong advocate on scientific medical research and evidence-based information, and constantly want to differentiate between marketing hyperbole and real world effects.

Good product

Posted by 5615947238678687463 on Sep 28, 2016

I take L-Optizinc daily to combat BPH (prostate swelling) etc and trust the Now brand. Have weaned myself off BPH prescription medications after 10 years by taking key supplements and minimizing intake of processed foods and gluten. Zinc is a key ingredient in this management.

I don't know if as good as picolinate

Posted by 4776688042352802320 on Aug 02, 2016

I don't know if as good as picolinate. I used ZincPicolinate just before, but switched to OptiZinc because is supposed to be as bioavailable, and picolinate really has a plastic smell and taste. But it seems like it is not working as wel. With picolinate no colds, now I have one. With picolinate , "my manhood" got a push in the back, wit optizinc feel no difference.
