These capsules are tiny, requiring no effort at all to swallow. They have no flavor at all. They are chelated which should improve bioavailability. (absorbency????) Consumption along with meals should improve that further but please consider the other foods in that meal. Acidic foods should improve absorption further. One limitation is the quantity of green vegetables in the meal. Oxalates, phosphates, and a few other components of vegetables are considered to be anti-nutrients, blocking the absorption of many minerals. Very few people are deficient in zinc and excess zinc blocks the absorption of iron and copper. Common recommendations are 40 mg per day. These capsules each provide 50 mg. That should not be a problem if one does NOT consume this product every day. Zinc bioavailability seems to decline with age while iron and copper may accumulate to harmful levels. It is safe to consume one capsule per day. For other reasons, my wife and I consume 2 capsules on one day out of 4 and we have not encountered problems with any blood or urine test. DO NOT consume these if you wear false teeth. Some creams used as adhesives MAY already deliver an unsafe level of zinc. There is a homeopathic supplement claimed to prevent colds that itself delivers a questionable excess of zinc, especially when administered multiple times per day. One should not mix products driven by science (as above) with unregulated faith-healing products like homeopathy. Read more
