While alpha lipoic acid, selenium, vitamin D, and n-acetylcysteine have recommended daily intakes for supplementation described in our Blended Standard, the polyphenols resveratrol, EGCG, silibinin, quercetin, and curcumin do not. For these nutrients NutriSearch has searched the literature for each nutrient to determine a suggested daily intake within physiological range that is known to elicit a cellular response. The daily values of intake explained in the previous sections, while not specifically shown in the Blended Standard (page 84, NutriSearch Comparative Guide to Nutritional Supplements™ for the Americas, sixth edition), are imbedded in our analytical model.
This criterion assesses the product for the presence of these nutrients and compares their potencies to the suggested values of intake as determined from the literature or our Blended Standard.
Does the product contain resveratrol (suggested daily intake of 20 mg), epigallocatechin gallate (suggested daily intake of 3.5 g for green tea leaf or 584 mg for the extract), silibinin (suggested daily intake of 50 mg), quercetin (suggested daily intake of 50 mg), curcumin (suggested daily intake of 100 mg), AND does the product contain alpha lipoic acid, selenium, vitamin D3, and n-acetylcysteine at potencies up to 100% the potency in the Blended Standard?
