Resveratrol, Metabolism and Bioavailability

Normally resveratrol does not absorbed efficiently when taken orally. A recent research conducted on a group of 10 men and 5 women, they were administered with 25gms of resveratrol each, but when their blood samples were taken to lab to analyze its absorption, only traces of resveratrol were merely available.

So there is a requirement of better medium that overrides the fast metabolic characteristics of resveratrol. Herbal vendors like Source Naturals and Solary came up with the better composition that shows better absorbing properties.

Negative Side Effects of Resveratrol

Reason for many negative Resveratrol side effects is consumption of Resveratrol in lesser dosage or the intake exceeds the normal level. We recommend starting moderate dosage that should be between 20mg to 50 mg and increase this gradually, stay below 500 mg dose, and do consider your own body size and health conditions.

Lot of research has been done on negative side effects of Resveratrol, very few cases has been came into observation for example:

Resveratrol does have mild estrogenic activity so we cannot recommend for women during their nursing or pregnancy period due to possible anti-growth side effects.

Resveratrol acts as a blood thinner so it is not recommended for people who are already taking blood thinning medicines.

Using Resveratrol from cheap vendors may result in unhealthy conditions like diarrhea, abnormal blood tests, over thinning of the blood, headaches, and anxiety. But don’t worry these results are normally reversible.

Drinking red wine too much to gain maximum level of Resveratrol will result in negative effects and cause some serious harm.

Resveratrol has been in use since long and it is listed safe when taken properly and as far as negative side effects are concerned, you can avoid them by taking proper dosage from good vendors and after seeking the right advice from right person.

Resveratrol actually improves your energy levels and digestion process. Also there was a research carried out by scientists of Illinois that shows that mice feed include Reveratrol made 10% fats as compared to mice using plain feed without Resveratrol.

Technically a perfect digestive system can reduce major causes of obesity and can help feeling better. So it is not a miracle or myth that Resvertrol is effective for weight loss.

1 ounce of red wine averages 160 µg of Resveratrol, compared to peanuts, which average 73 µg per ounce. Since wine is the best dietary source after Resveratrol Supplement by Source Naturals.

Natural Sources of Resveratrol

Resveratrol is naturally present in plants and foods like eucalyptus, spruce, lily, mulberries and peanuts but most abundant source of Resveratrol’s most abundant natural sources are Vitis vinifera, labrusca, and muscadine grapes, which are used to make wines.

It occurs in the vines, roots, seeds, and stalks, but its highest concentration is in the skin of grapes, which contains 50-100 micrograms (µg) per gram. Grapes grown in cooler places are found to have higher concentrations.

Resveratrol as a drug to prevent Cancer.

Topical applications of reveratrol have been effected for the treatment of mouse for skin damage as a result of UVB exposure. If we talk about oral medications than huge amount of resveratrol is required to show positive effects on treating cancer.

The strongest evidence of anti-cancer action of resveratrol exists for tumors, such as skin and gastrointestinal tract tumors. For other cancers, the evidence is equivocal, even if massive doses of resveratrol are used.
