A. The material we use is a mixture of pyridoxine and alpha-ketoglutarate, which contains 52.0% pyridoxine and 45.0% alpha-ketoglutarate.1Alpha-ketoglutarate is a intermediate of the Krebs cycle (Citric Acid cycle).2 It plays an important role in amino acid metabolism.3Nicotinamide is the amide of niacin.

A. Each serving of Krebs Magnesium-Potassium Complex provides 250 mg of magnesium and 100 mg potassium to support healthy heart muscle function.† Formulated with absorbable forms of these two important minerals, Krebs Magnesium-Potassium Complex offers cardiovascular support in a convenient once-daily tablet.† A review of the established health resources indicates that the upper limit for magnesium is 700 mg, while no upper limit has been established for potassium. Based on these limits, one could safely take two tablets daily and still remain under the upper limit. However, we suggest you consult with your healthcare practitioner to determine the best supplement regimen as your diet and dietary supplement use may alter your mineral needs.

A. The dose of magnesium and potassium per serving is the same. However, the serving size is now 2 tablets vs. 1 tablet. The reason is that the process of fully reacting minerals results in a finished ingredient that has a lower elemental value of the mineral being delivered. Therefore, it takes more powder to deliver the same amount of the mineral. What was delivered in 1 tablet, now requires 2 tablets.
