Does beta sitosterol really work?
Beta-sitosterol is most commonly used for lowering cholesterol levels and improving symptoms of an enlarged prostate (benign prostatic hyperplasia or BPH). It is also used for other conditions, but there is no good scientific evidence to support its other uses.
Does phytosterols reduce testosterone?
I point out that daily intake of 500 to 1,000 mg of cholesterol may result in an approximate increase of 130 ng/dL of total testosterone in men. In rats, the ingestion of phytosterols for 22 days reduced serum testosterone by 33%, in comparison to controls.
Are phytosterols and plant sterols the same?
Phytosterols, also known as plant sterols or stanol esters, are naturally occurring compounds found in plants that are similar in structure to cholesterol found in humans. When consumed in the foods you eat, they compete with cholesterol for absorption in the intestine.
Can phytosterols raise blood pressure?

How are phytosterols similar to cholesterol in plants?
Phytosterols are phytosteroids, similar to cholesterol, that serve as structural components of biological membranes of plants. They encompass plant sterols and stanols.
How are phytosterols regulated in the human body?
In fact, you have two enzymes called sterolins that regulate which sterols can enter your body from the gut. ). Phytosterols are the plant equivalents of cholesterol in animals.
Are there any health benefits to taking phytosterols?
Human studies show that people who consume the most phytosterols have a lower risk of stomach, lung, breast, and ovarian cancer (18, 19, 20, 21). Studies in animals also indicate that phytosterols may have anticancer properties, helping to slow the growth and spread of tumors (22, 23, 24, 25).
