Regarding the use of resveratrol, various side effects were experienced and they are listed here as reported by the users. The list is unreliable and can be considered as without any scientific basis. The use of placebo cannot be ignored and are rendered possible under the circumstances. A more accurate list will be posted once the FDA trials of companies especially Sirtris Pharmaceuticals are already complete:
1. A buzzed sensation just like being high on caffeine. Others describe this as a dizzy spell.
2. Insomnia lasting in different durations of time. Extended time ranging from one to two weeks was experienced by some.
3. Elevated rise in blood pressure levels with irregular readings in the “high” range.
4. Diarrhea and stomach cramps which can be attributed to emodin content. This was confirmed through a certificate of authorization coming from an independent laboratory. Emodin is found in low quality or pure resveratrol supplements.
5. Joint pains in feet, hands, and hips comparable to arthritis or tendonitis as claimed by some.
6. Increased sensitivity either to hot or cold temperature. This is probably due to vein dilation or circulation affecting the sense of touch.
7. Numbness particularly in the extremities.
8. Palpitations of the heart.
9. Symptoms similar to flu or minor colds.
10. Augmented adult acne.
11. Urine coloration.
One important thing to note here is the fact that these resveratrol side effects were experienced by users and were only compiled under this site. No further verifications were made whether the users are taking medications, multiple supplements, or have any other medical conditions. Just the same, it is worth mentioning that resveratrol side effects can be triggered by other medications.
Hence, prior discussions with your doctor are needed before taking resveratrol to avoid its adverse effects. He is in the best position to give you the proper advice whether to take resveratrol or not.
Personally, I also experienced some of the resveratrol side effects listed above but none of them outweigh the potential benefits derived.
Positive Side Effects as Compiled
The use of emerging products usually encounters some resistance regarding its use. However, listed hereunder are the reported positive resveratrol side effects as personally compiled:
1. Mental alertness. Increased concentration periods than the normal patterns.
2. Lowered bowel sensitivity due to Irritable Bowel Syndrome (IBS).
3. Endurance athletes like swimmers, runners, and cyclists noted enhanced performance by going extra distance and improvement in time.
4. Improvement in the cholesterol levels with decrease in LDL cholesterol (bad) and increase in HDL cholesterol (good).
In order to avoid probable resveratrol side effects:
- Women with sensitivity to estrogen and cancer should initially consult her doctor prior to the taking of resveratrol. This is due to the fact of its mild estrogen activity wherein no clinical studies have yet been made regarding the effects on humans.
- Pregnant women and children
- Nursing mothers
- Women preparing to conceive a child
- People under blood thinning medication. Resveratrol has innate blood thinning properties which is one of the reasons why it is noted to have healthy effects to the heart.
- People using other prescription drugs
In all cases, the likely side effects of resveratrol can be avoided if there will be proper consultations with your doctor.
