Trans-Resveratrol Dosage: How Much Should You Take?
Human studies have used anywhere from a few milligrams to several grams of resveratrol a day. Here's how to make sense of the numbers — and where 125 mg fits.
There is no "official" resveratrol dose
Resveratrol isn't an essential nutrient, so there's no Recommended Daily Allowance. The 2024 systematic review of 194 clinical studies found doses ranging from very small amounts to several grams per day, and concluded there's no consensus regimen for any specific condition. So the honest answer to "how much should I take?" is: follow the label of a well-made product, and involve your doctor if you have health conditions or take medication.
Doses used in human research
| Daily dose range | How it's typically used | Notes |
|---|---|---|
| Under 50 mg | Some early and dietary-level studies | Close to what a resveratrol-rich diet could provide |
| 100–250 mg | Common in healthy-aging, metabolic and brain studies | SelfPlus AGE+ (125 mg) sits here |
| 500–1,000 mg | Many metabolic and cardiovascular trials | Generally well tolerated up to 1 g/day |
| 2,500–5,000 mg | Short-term, often in disease settings | Digestive side effects more common |
More isn't automatically better. Some studies suggest resveratrol has "hormetic" effects — beneficial at moderate levels, with diminishing or different effects at high doses. Moderate daily doses also keep the risk of side effects and interactions lower.
Trans-resveratrol vs "resveratrol" on labels
Labels can be confusing. Some list the total extract weight ("Resveratrol 500 mg") when only part of it is trans-resveratrol. Always look for the trans-resveratrol number. On the AGE+ label, 250 mg of Japanese knotweed extract at 50% gives exactly 125 mg of trans-resveratrol.

Check Availability →When and how to take resveratrol
- Once a day is fine. Resveratrol is processed quickly, but a daily routine keeps a steady supply coming in. The SelfPlus AGE+ label directs one capsule daily.
- With or without food? Either works. Some people take it with a meal containing fat for comfort and possibly better absorption. Food may slow absorption a little but doesn't stop it.
- Morning or evening? There's no strong evidence either way. Pick the time you'll remember — consistency matters most.
- How long? Many trials ran 8 weeks to 6 months or more. Plan on at least a few months before judging.
- Don't double up. If you miss a day, just carry on the next day.
Who should adjust or avoid resveratrol
Talk to your doctor first if you take blood thinners, antiplatelet drugs or medicines processed by liver enzymes (CYP3A4, CYP2C9), if you have a hormone-sensitive condition, if you're pregnant or breastfeeding, or if you have surgery coming up. See our side effects guide.
Is 125 mg enough?
125 mg is a moderate dose that sits within the range used in many human studies, while staying well below the gram-level doses linked with digestive upset. It's a sensible daily amount for people who want consistent, long-term healthy-aging support rather than a high-dose experiment. If your doctor recommends a different amount for you, follow their advice.

Quick questions
Can I take two SelfPlus AGE+ capsules a day?
The label directs one capsule daily. Don't exceed it unless your doctor specifically recommends a different amount for you.
Should I cycle resveratrol?
There's no solid evidence that cycling is necessary. Most human trials gave resveratrol daily for weeks to months. If you want a break, discuss it with your healthcare provider.
Does resveratrol need to be taken with fat?
It isn't required. Some people take it with a meal for comfort and possibly better absorption. The most important thing is taking it consistently.
