What You Should Know
Nutravina, a relatively new entrant on the health supplement scene, manufactures and markets products containing resveratrol, a natural substance derived from such fruits as purple grapes, pomegranates, raspberries and blueberries. Advocates believe resveratrol to have many health benefits, among them anti-aging properties. Although people can enjoy the benefits of resveratrol directly by consuming those fresh fruits or wines where it naturally occurs, Nutravina asserts that in order to consume a consistent supply of the substance, people should take it in supplement form.
There actually has been extensive laboratory testing on the efficacy of resveratrol in promoting cardiovascular health, preventing or retarding cancerous growth, extension of lifespan, and helping to prevent atherosclerosis and Alzheimer’s disease. However, this scholarly research has been limited to studies involving mice and other lab animals. The leap from these studies to human applications is purely speculative.
Nutravina markets three products: Reserveatrol Anti-Aging Compex, Reserveatrol 100, and Reserveatrol 250. Marketing materials state that these formulas are designed to “help activate your longevity genes as well as reduce damages caused by free radicals.” They also claim that resveratrol repairs DNA, benefits genetics regulators, and aids in mitochondrial biogenesis. Pretty sweeping claims that, although may be partially true in lab tests with animal subjects, are not scientifically substantiated or supported by research with human beings.

- Scientifically researched
- Active ingredients are naturally occurring in certain fruits
- Timed-release formula to maximize absorption
- Research not conducted on humans
- You can pay less for fresh fruit and get the same benefits
- Because of fairly rapid degradation in the body, you may not get the full benefit of active ingredients
Nutravina’s Reserveatrol supplements contain resveratrol, a substance produced in such fruits as raspberries, pomegranates, and dark grapes. While many health benefits are attributed to resveratrol, the truth is that scientific research has borne out only some of these benefits, and even then, only on laboratory animals such as mice, not humans. Since you can glean the same benefits from eating the fruits which contain resveratrol, you might consider saving money by enjoying freshly harvested fruits that are low in calories and chock full of nutrition.
