If you take vitamins or nutritional supplements in tablet form, the digestive process requires up to four hours! Saliva, enzymes, hydrochloric acid, and at least one vitamin-binding protein are required to break down the fillers, binders coatings and lubricants delivering only 10-20% of the nutrients bioavailability to your body. This means that if you take 1000 mg pill of Calcium, you are likely to get 100-200mg usable by the body at best with an 80% loss of strength. Isotonix nutritional supplements are powder vitamins that once mixed with water cut this process down to 5 minutes with a 20% of loss of strength.
