Why You Need It
- Reduces Inflammation: Helps calm the body's inflammatory response naturally.
- Supports Liver Health: Known to protect liver cells from oxidative stress.
- Antioxidant Power: Fights free radicals that damage healthy cells.
- Sensory Experience: Contributes to the unique, pleasant tastes of certain herbs and fruits.
Deep Dive
Megastigmane glycosides are structurally related to carotenoids, the pigments that give fruits and vegetables their yellow, orange, and red colors. While they are primarily known for contributing to the aroma and taste of foods (like the scent of tea leaves or the flavor of unripe mangoes), emerging research highlights their biological activity.
Once ingested, the sugar molecule (glycoside) is cleaved off, releasing the active 'megastigmane' moiety. This active form is believed to inhibit specific inflammatory pathways in the body, making it a popular extract in high-end skincare and dietary supplements aimed at soothing the system.
Natural Food Sources
Because these compounds are found in plant pigments and essential oils, the best way to get them is by eating a colorful, varied diet rich in herbs, spices, and produce.
| Food | Amount | Notes |
|---|---|---|
| Sorrel (Leaves) | High | One of the richest natural sources; gives a distinct tangy flavor. |
| Mango (Unripe/Peel) | Medium-High | The skin and flesh of unripe mangoes are rich in these compounds. |
| Carrots | Medium | Specifically found in the peel and outer flesh. |
| Tea Leaves | Medium | Contributes to the complex aroma of green and black teas. |
| Ginkgo Biloba | Medium | Often extracted for supplement use, but naturally present in the leaves. |
Supplementation
Usage: Supplements usually contain a standardized extract (often labeled as Sorrel extract or Mango leaf extract).
Dosage: There is no standard Recommended Dietary Allowance (RDA) for Megastigmane glycosides as they are non-essential phytonutrients. Typical supplement dosages range from 100mg to 500mg of extract daily, depending on the concentration of active compounds.
Who should take it? Those looking for natural anti-inflammatory support, individuals concerned with liver health, or anyone wanting the benefits of sorrel/mango without the sugar content of the fruit.

Frequently Asked Questions
Safety & Side Effects
Safety Profile: Megastigmane glycosides derived from food sources are generally considered Very Safe (GRAS status for food consumption).
Side Effects:
- Mild digestive upset if consuming in massive quantities (e.g., eating a pound of sorrel at once).
- In supplement form, always check for fillers or additives.
Who should avoid it?
- Pregnancy/Breastfeeding: There is insufficient data on high-dose extracts. Stick to food sources.
- Allergies: If you are allergic to sorrel, mango skin, or Ginkgo, avoid concentrated supplements.
- Surgery: As with any anti-inflammatory agent, discontinue use 2 weeks before scheduled surgery.
