You can compare Ultra A / Z in principle even quite well with the (several times as expensive) Centre "A to Zinc". The biggest difference is that Centrum is precisely dosed in a tablet as two of Ultra A / Z. With a daily dose you get from most vitamins 100% RDA, for vitamin E and C significantly more. As Antioxidant really well thought out. Although minerals are virtually all in place, but rather sparse dosed. But anyone who simply wants to have a good conscience an all-round primary care, is all right here.
You just have to be aware that here only merely inorganic compounds of minerals are used, which can be generally worse absorbed by the body, as high-quality organic. This can be seen in the list of ingredients: calcium carbonate, magnesium oxide, zinc oxide, copper sulfate, etc. This has only one reason: These inorganic forms are simply cheaper! If you use high quality compounds that the body can absorb well (eg, citrate and gluconate), would this product easily cost five times as much, and the tablets would be three times as large.
Therefore you just have to always put the price in comparison to the performance. And the aforementioned Centrum product is therefore quite comparable, because even there the same less-quality links are used, Centrum but compared to the content of which is about three times more expensive. Therefore, the Ultra A / Z are priced absolutely attractive. Rounding out the whole thing with green tea extract (EGCG, particularly the English Wikipedia has some info here), of which one now assumes that it can contribute to the prevention of cancer, Alzheimer's and other. Really not a bad idea.
Conclusion: 4 stars. 5 simply are not there, because even though price / performance voices, the minerals contained remain still rather poor.
