The supplement offers some protection against obesity as found in laboratory studies published in the Journal of Biological Chemistry in 2011. Rats were fed high fat diets as well as given this supplement and were compared to a group that received a placebo.
The group given resveratrol did not show the range of negative effects associated with obesity, like high LDL bad cholesterol, high blood pressure and the hardening of the arteries. It also provided protection against insulin resistance which is a pre-cursor to Diabetes.
The Mediterranean diet has many foods which are also rich in Resveratrol such as berries, nuts and pomegranates as well as including the consumption of red wine. The diet consists of good fat foods such as olive oil.
Resveratrol supplements may be used to obtain more of this active ingredient than from food alone. While some studies show that red wine is a good source of this anti-oxidant, it is not recommended to drink more than one glass of wine a day for liver health.

Buying the Best Resveratrol Supplements
Before purchasing Resveratrol extract in pill or capsule form, it is recommended to read user reviews of any prospective vendor. Certain brands are viewed as providing better quality product and better potency of ingredients.
Here is a check list to review before you decide on the best brand to buy.
- Determine whether the active form of resveratrol, Trans-resveratrol, is used as opposed to the inactive form, which is cis-resveratrol.
- Supplements should be 99% pure of 100 mg per serving with no fillers or flowing agents or large amounts of emodin.
- Emodin is linked to certain side effects. The emodin content of 98% resveratrol is low, usually much less than 1% or a 50% resveratrol product. These can contain up 2% emodin and may have a laxative effect.
- Be sure also to only buy supplements that state a lab has tested them to be free of contaminants. Big chain stores have been found selling supplements with contaminants or low purity scores. High-end speciality retailers that perform more extensive testing may provide better quality products.
Contraindications for Resveratrol
Emodin is a compound that can be found in some types of Resveratrol extract. There are concerns emodin can cause liver and kidney damage if used long-term and can cause sudden and severe diarrhea in higher amounts. Severe nausea and diarrhea have been reported in products that did not use the pure form of resveratrol.
The same result has been recorded in products that use higher than 50% resveratrol made from Japanese Knotweed (Polygonum cuspidatum), which has an emodin component. It is a cheaper source for some manufacturers because the plant is available year round as opposed to sourcing it from grapes.
Experts recommend avoiding these products and instead buying Resveratrol from grapes.
If taking blood thinners or if on blood pressure medicine or taking herbal supplements such as St. John’s Wort, Garlic or Ginkgo Biloba Leaf, this supplement should be avoided.
People taking medications for antiviral and antifungal conditions, any of the NSAID painkillers or medications that change in the liver, or if having cancer treatment shouldn’t take this supplement. It should be discontinued two weeks before surgery.
It is thought to be safe during pregnancy and breastfeeding if used from non-alcohol sources.
