  • ENADA, NADH, 5 mg., 30 Tabs
• Here's one that does not contain Povidone: by Ecolgical Formulas; I called them to verify that they don't use the patented ENADA formulation [(800) 275-3495]. Here are all the ingredients of the EF product, taken off the bottle in front of me:
  • 1.8 mg NADH
  • Sorbitol, Methyl Cellulose, Potassium Bicarbonate, Magnesium Stearate, Tocopherol Succinate
• Unfortunately, on my first trial of this it gave me a headache, and no energy. Will try a lower dose later.
• Alpha Ketoglutaric Acid
• L-Carnitine
