Several main reasons for the fallibility of most vitamin and mineral supplements exist. One reason is a relatively low "bioavailability rate" of the supplement. Bioavailability is the measure of how much an administered drug or supplement is absorbed into the bloodstream and actually reaches the intended site of action in the body. Many grocery store-quality supplement tablets are so full of binders and fillers that any vitamins and minerals actually in the tablet have very little bioavailability - up to just 10 percent. Capsules fare a little better - about 20 percent on average.

Another reason is that dietary supplements (vitamin and mineral supplement products) are not required to undergo review by the U.S. Food and Drug Administration (FDA) prior to being marketed unless they contain new dietary ingredients. The responsibility for the safety and efficacy of a supplement rests with the manufacturer. Make no mistake. The dietary supplement business is a multi-billion-dollar business. Manufacturers are out to make money and so long as a supplement is safe, there is no monitored requirement that it also be effective.

The third primary reason that anti-aging supplements often don't work is because even the highest quality supplements can't make up for a poor diet, lack of adequate exercise and sleep, or unhealthy habits like smoking and excessive alcohol intake.

In creating the Reviva anti-aging vitamin line, the Drs. Garcia of Garcia Facial Plastic Surgery near Jacksonville, FL, drew upon years of medical and nutritional experience and research. They worked hand-in-hand with compounding chemists to develop a line of highly potent products that provide the body supranormal levels of healing vitamins that help the body maximize its cellular functions.

The Reviva line includes three stages: Stage I is a multivitamin formulated to keep the body's cellular functions working at maximum levels; Stage II contains anti-oxidants proven to combat the ill effects of free radicals on skin, boost metabolism and help prevent cardiovascular disease. Stage III is a healing formula designed to aid the body in times of stress and healing. Garcia's facial plastic surgery patients who took Reviva anti-aging vitamins during the peri-operative stage reported less swelling and bruising and quicker recoveries.
