Actiflax is an extract containing SDG (secoisolariciresinol diglycoside) antioxidant found in flaxseed, sunflower and pumpkin seeds. It affects the level and activity of estrogen by inhibiting the growth of cancer cells (reduces the risk of female breast cancer). It improves metabolism and neutralizes free radicals. It is anti-atherosclerotic and anti-diabetic. SDG is rarely used in the sports supplementation.
