Nutritional supplements require “fillers” to deliver key ingredients to your body. Most supplements use inorganic chemicals such as magnesium stearate that, although cheap, can actually inhibit nutrient absorption. Others use soybean oil which is a source of unwanted hydrogenated fat. Even others use silicates or talc, common agents in deodorants. The fillers in AlphaSperm were designed by a cancer nutritionist and are based entirely fillers offered to nutritionally challenged cancer patients in whom high absorption and bioavailabity of nutrients is essential.
