I have personally tested all the products we carry, and have found them to work extremely well for "nearly every body." Once in a while, there are a few exceptions to the rule, but most of these products test very high—often at the level of "needs" or "needs badly"—for most people. This is why I have decided to carry them.
The ones that deal with specific issues—such as the thyroid or adrenals—would only be recommended for people experiencing a challenge in those particular areas. If you have any specific allergies—to strawberries, seafood, dairy, etc.—you may want to check with us before purchasing any supplements, so we can make sure they are right for your body.
