Wellpath's Boost Elderberry Gummies is a natural formula that contains 100 mg of Sambucus Nigra Extract, 90 mg Vitamins C and 7.5 mg of zinc. Much like Bioschwarz, Wellpath's formula lacks a lot of the ingredients that limit its ceiling as an elderberry supplement. Unfortunately, WellPath has no return policy, making all sales final. But their formula is decent enough to earn a spot on our list.
