Alpha Lipoic & R-Lipoic AcidWith Probiotics, Anti-Aging Nutrients and Full Spectrum Whole FoodsAntioxidant SupportDietary Supplement Nutritional Support for Overall Well-Being. Nature's Plus Ultra Lipoic Mini-Tabs delivers 500 mg Alpha Lipoic Acid, and an additional 100 mg of R-Lipoic Acid for total body antioxidant, anti-aging nutritional support. Alpha lipoic acid is the premier rejuvenating antioxidant for the widest range of tissues. Proven effective in "high-energy" tissues like the heart, brain, kidneys, nerves and muscles, as well as in "low energy" tissues, such as blood cells, connective tissues and endothelium, alpha lipoic acid is a well-rounded whole-body antioxidant. But Nature's Plus takes lipoic acid supplementation to a whole new level with an additional 100 mg of R-Lipoic Acid for even greater support of high-energy tissues. Cells that need more energy make far better use of R-lipoic than any other form. R-lipoic is the form that target free radicals in those tissues (heart, brain, kidneys, nerves and muscles), helping them function more cleanly and efficiently. The extra 100 mg of R-Lipoic antioxidant power in Nature's Plus Ultra Lipoic Mini-Tabs yields an unmistakable sensation of vitality that no other lipoic acid supplement can match. For even greater synergistic activity, Nature's Plus Ultra Lipoic Mini-Tabs further supplies Lactobacillus acidophilus and other healthful probiotics, as well as time-honored standardized botanical extracts and proprietary full spectrum whole food blends. Revolutionary bi-layered delivery provides rapid and extended Lipoic acid support for total health. Nature's Plus ultra Lipoic is your complete, energizing, rejuvenating antioxidant and anti-aging lipoic acid supplement
