The most significant ingredient, Beta-Sitosterol, may impact testosterone and dihydrotestosterone (DHT).  This can cause erectile dysfunction and a decrease in sex drive.  In the event of these side effects, you could use a male enhancement product to increase testosterone levels; however, I am not sure of the side effects associated with them.

This natural supplement can actually reduce the absorption of vitamins, especially vitamin E and beta-carotene.  In this instance, you can take supplements to counteract these deficiencies. 


  • Eat a low-fat diet.
  • Increase plant protein and decrease animal protein. 
  • Decrease the amount of red meat eaten.

Beta-sitosterol, a substance found in fruits, vegetables, nuts, and seeds, has plenty of promising medical functions. Primarily, it lowers cholesterol, which lowers risk of cancer and heart disease.

  • It also treats benign prostatic hyperplasia (BPH), or enlargement of the prostate,
  • by reducing inflammation and treating urination problems.

However, any ingredient with powerful effects may also have a risk of side effects. Let’s look closer at beta-sitosterol and its side effects so you can determine whether it’s right for you.

In order to examine long-term safety of beta-sitosterol and other plant sterol esters, scientists examined the effects on volunteers who ate a 20 g spread enriched with 1.6 g plant sterols daily for one year. The spread consistently lowered cholesterol.

Also, beta-sitosterol may lower sexual desire and cause erectile dysfunction. This is because beta-sitosterol affects male hormones such as testosterone and dihydrotestosterone.[4] Again, reactions are different for each individual.

How does Beta-sitosterol work?

Beta-sitosterol is a plant substance similar to cholesterol. It might help reduce cholesterol levels by limiting the amount of cholesterol that is able to enter the body. It can also bind to the prostate to help reduce swelling (inflammation).

Beta-sitosterol is safe for most people. It can cause some side effects, such as nausea, indigestion, gas, diarrhea, or constipation.

Beta-sitosterol has also been linked to reports of erectile dysfunction and loss of libido.

More Evidence!

Men can also experience sexual side effects of beta sitosterol. This supplement has been known to decrease the sex drive and cause erectile dysfunction. These symptoms go away when the patient stops taking beta sitosterol and are not generally a cause for concern, especially if the patient is taking this supplement for only a short period of time.
