Health Benefits & Sources
Why You Need It
- Cholesterol Management: Like its cousin sitostanol, it helps block the absorption of cholesterol in the gut.
- Cellular Integrity: It contributes to the structural stability of cell membranes, particularly in plants and fungi (and when consumed, can influence ours).
- Antioxidant Support: As a plant sterol, it possesses mild antioxidant properties that help protect cells from oxidative stress.
Deep Dive
Ergostanol functions primarily as a structural lipid. However, the most practical application for the everyday person is its role in lipid metabolism. Research suggests that when consumed alongside dietary fats, phytosterols like Ergostanol compete with cholesterol for uptake in the digestive system. By taking up space in the micelles (small fat carriers), they effectively reduce the amount of cholesterol entering your bloodstream. While not as potent as sitostanol or beta-sitosterol (which are more common), Ergostanol contributes to the overall 'sterol load' found in a diet rich in plants, nuts, and seeds.
Natural Food Sources
Ergostanol is typically found alongside other sterols. You won't find it concentrated in one specific fruit, but it is part of the general sterol profile in fungi and certain plant tissues.
| Food | Amount (Est.) | % Daily Value |
|---|---|---|
| Oyster Mushrooms | 20-40 mg | Low |
| Pistachios | 10-20 mg | Very Low |
| Corn Oil | 5-15 mg | Very Low |
| Wheat Germ | 5-10 mg | Very Low |
| Cocoa Powder | Trace | Trace |
Supplementation
Because Ergostanol is rarely isolated as a standalone supplement, you will usually find it as a minor component in Phytosterol Complex supplements.
- Dosage: There is no specific RDI for Ergostanol alone. However, total phytosterol intake for cholesterol management is typically recommended at 2 grams per day.
- Usage: Take phytosterol supplements with meals to maximize the cholesterol-blocking effect.

Frequently Asked Questions
Safety & Side Effects
Ergostanol is generally considered safe as a natural dietary component.
Who should avoid it?
- Sitosterolemia patients: This is a rare genetic disorder where the body absorbs too much plant sterol. Avoid all supplements containing Ergostanol.
- Pregnancy/Breastfeeding: As there is insufficient data on high-dose intake, stick to food sources only.
Potential Side Effects:
- High doses (usually over 3g of total sterols) may cause mild digestive upset, such as nausea or diarrhea.
