Whole Health Solutions encourages you to know the reasons to use specific supplements. Always discuss everything you take with all your healthcare providers. Wherever possible, obtain nutrients from a good diet, although higher doses may be needed for treatment. Evaluate your supplements for quality, purity and evidence for effectiveness. All supplements we offer have been evaluated to contain pharmaceutical grade ingredients, to contain the listed dosages, and to avoid allergens and impurities. Please remember that supplement use may be supported by basic science research but often lacks consensus of large double-blind randomized controlled trails.
