Resveratrol is a compound which can be found on grapes, berries, nuts, red wines, and other fruits and plants. Research shows that resveratrol have effects on heart-related diseases, obesity, longevity, cancers, and aging problems. However, too much intake of the said compound may show adverse side effects. Therefore, manufacturers boldly tell consumers warnings and possible side effects that you may encounter if instructions are not followed and without the doctor’s advice. Below is the list of resveratrol side effects.
Stomach ache and other intestinal disorders. Resveratrol is associated with emodin—a substance which have the same effects as laxative. Most Japanese would often this compound in laxative herbal teas—proof that it really does contain emodin. It can also cause stomach ache, irregular bowel movement, diarrhea, and other known intestinal disorders. However, this is only possible if the resveratrol supplement that you take contains less than 50% trans-resveratrol. Those supplements that are made of high quality ingredients with 99% purity trans-resveratrol and muscadine grapes will not give you this side effects. An example of this is the product known as Perfect ResGrape. This product contains all natural ingredients, 99% trans-resveratrol, and muscadine grapes. As for these grapes, studies show that it could be the highest type of grapes as it surpasses other health benefits from other grapes. So whenever you are choosing the best kind of resveratrol product, make sure that it contains these basic components.
Jitters, insomnia, and tendinitis. Aside from emodin, there are also some minor resveratrol side effects that these are only the known side effects that have been reported from other manufacturers. Since tests are only done on mice and other animals, researchers say that there may probably have other unknown side effects that may arise—and these are still being studied by expert scientists.
As for long term disease and side effects derived from resveratrol, there has no reports coming from any manufacturers of the said compound.
