Beta- Sitosterol is a phytosterol (plant sterol) that has a chemical structure similar to 
that of cholesterol.
Natural Sources:
Beta – Sitosterol is found in aloe vera, berries especially acai berry and goji berry, lemon, persimmon, sea buckthorn, alfalfa sprouts, amaranth, avocado, beets, pumpkin seeds, nuts especially peanuts, rice bran, soybeans, and wheat germ.
Athletic Benefits of Beta – Sitosterol:
- May prevent from athletic overtraining syndrome.
- May reduce post – exercise infection especially when combined with colostrum.
Non – Athletic Benefits of Beta – Sitosterol:
Beta – Sitosterol reduces symptoms of enlarged prostate (BPH; benign prostatic hyperplasia) especially if combined with saw palmetto and nettle tea. Other benefits are:
- Promotes cardiovascular health.
- May reduce cholesterol level by blocking absorption of cholesterol.
- May have a protective effect against gallstone formation by lowering cholesterol in bile.
Dosage:
For BPH and cardiovascular health, Beta – Sitosterol is usually taken 100 – 500 mg a day. To help reduce cholesterol level, 500 – 1000 mg a day would be an ideal. For athletes, we recommend 1000 – 2000 mg a day. When combined with “colostrum”, Beta – Sitosterol shows better results in athletes.
Caution: 
Beta – Sitosterol can convert in the body into sequalene, which acts as a precursor for steroid hormones and vitamin D.
There are reports that taking Beta – Sitosterol might cause athletes to have positive tests for Equipoise (Boldenone). It is a veterinary steroid hormone abused by athletes and banned in sports. This is why you should exercise caution when taking Beta – Sitosterol during in-competition seasons.
