Since I started taking vitamins on a regular basis, I stopped getting sick. At most it was a runny nose for a couple of days or a sore throat for a day, with a minimal increase in temperature.I also noticed that my hair stopped falling out and got thicker. The ponytail is getting much thicker. So for those who have problems with hair, I can also recommend it.The brand 21 Century is the one of my favourites. I also took Biotin and Selenium of this brand.

My zinc levels are usually low from taking Nexium, but they had been dipping low enough to cause secondary health issues even with regular supplementation. After 3 months of taking this supplement my levels are normal. I would highly recommend this product for anyone suffering from proton pump inhibitor (antacids) related zinc deficiency. Zinc Citrate is the best/most easily absorbed form, as shown in several peer reviewed journal articles. But, after taking this supplement, I can say anecdotally, that it really makes a difference when you use the citrate form of zinc.

Zinc citrate is the most effective regarding the absorbability from the gut into the blood. It is vital for skin, immunity, red cells, and connective tissues. It is gentle and tolerable. No notable side effects. It is thought that Zinc, along with Calcium and Magnesium, can overcome osteoporosis and osteopenia because of the synergism between these elements that potentiate the targeted effects and minimizes the adverse effects such as constipation. Zinc is aphrodisiac and is found naturally in marine foods. Size and baking are safe and practical. This product is perfect, especially in terms of price. I strongly recommend it!

Zinc is not one of those nutrients that you can just take without paying attention to what you are doing. Here are some important considerations:The RDA for adults, depending on which resource you consult and whether it is for males or females, and the referenced age, is somewhere between 8 - 14 mg for adults. The upper limit of safe intake is 40 mg. Notice that this product is 50 mg, and yes, that is OK, and that is because you will not absorb all of this zinc. However, zinc picolinate may be the best absorbed of the available supplements, as this form led to significant increases in hair, urine and erythrocyte zinc levels (Agents Actions. 1987 Jun;21(1-2):223-8). Other acceptable forms are Zinc Citrate and Zinc Gluconate. Some people do not seem to absorb Zinc ... MoreZinc is not one of those nutrients that you can just take without paying attention to what you are doing.

To be honest i don't know how to review this product, after i started taking this tablet i feel like i had some changes. I am sure energy level is one of them, I feel better immunity and I don't know what the remaining, Overall it's a great product.I do take it on an empty stomach or 2 hrs after having food in alternate days as i read somewhere, on an empty stomach you may feel bad for a few minutes, but will subside later.Zinc was not included in my diet, so this supplement helped me a lot. Am satisfied with the quality and its size.I recommend this product to some of my friends who have a similar diet. I will update this review in a few days.
