Allergy Research Group® has pioneered the development of buffered vitamin C products, and continues to offer the purest and least allergenic vitamin C products available. In addition to its hefty content of ascorbic acid, our buffered vitamin C also supplies potassium and the macrominerals calcium and magnesium at approximately one half the RDI per heaping teaspoon, which may make it desirable for individuals who do not regularly consume dairy products.*

The latest addition to our Buffered Vitamin C line is a unique cassava root (of the potato family) source Buffered Vitamin C, available in both powder and capsules. Cassava, or Manihot esculenta, is a bushy South American shrub with long tuberous roots, which are traditionally eaten like potatoes. Cassava root starch serves as the starting material for a multi-step chemical process of manufacturing ascorbic acid. It is well tolerated by individuals unable to tolerate other sources of vitamin C.*

Both the corn and cassava root sources are formulated with carbonates of potassium, calcium and magnesium, giving an acid-alkaline buffering action (pH 7.0 in water), potentially improving bowel tolerance and minimizing hyperacidity.*
