"I think you guys [gals ?] are the best. Free shipping on hammer products and super fast service. What's not to like?"

Nancy H.

Dear,

Proline Sports Nutrition & Equipment,

I was shopping for the product below using Google as which time I saw your Google add. This was the first I heard of your company. I went to your site and liked what I saw and proceeded to order the Optygen HP. The order was placed on late Friday afternoon and was delivered (to my surprise) on Saturday. Your service is awesome as well as your price match guarantee. There is no doubt that I will continue to use you in the future, as well as recommend you to others.

Regards,

 I am very impressed with your customer service.  I was worried about getting my order with a marathon a week and a half out.  Wow, less than 24 hours and my order was sitting on the porch.  That is phenominal service.  I will definately shop with you again.  I have had free shipping take 10 days.  Proline Sports Nutrition is a site I will recommend to my many running/cycling buddies.  Thanks for the great response.  BTW, that info on the Hammer Nutrition products was wonderful!!  It helped me hone in on my nutrition/hydration plan for my marathon.  I printed off the entire 120 pages!  This is my 4th marathon.  I've trained hard, and my Hammer plan I do believe will give me a PR.

Beta-Sitosterol

Beta-sitosterol alone and in combination with similar plant sterols reduces blood levels of cholesterol.1 2 3 This appears to be because beta-sitosterol blocks absorption of cholesterol.4 It has also been effective in reducing symptoms of benign prostatic hyperplasia.5

Although molecules quite similar to beta-sitosterol inhibit cancer cells in test tubes, the relevance of this information for people remains unknown.6

Where is it found? Beta-sitosterol is one of several plant sterols (cholesterol is the main animal sterol) found in almost all plants. High levels are found in rice bran, wheat germ, corn oils, and soybeans. Peanuts and its products, such as peanut oil, peanut butter, and peanut flour, are good sources of plant sterols, particularly beta-sitosterol.7

Rating Health Concerns
3Stars Benign prostatic hyperplasia
2Stars High cholesterol
1Star Athletic performance (in combination with beta-sitosterol glucoside for reducing the risk of post-exercise infection)
3Stars Reliable and relatively consistent scientific data showing a substantial health benefit.
2Stars Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
1Star An herb is primarily supported by traditional use, or the herb or supplement has little scientific support and/or minimal health benefit.

Who is likely to be deficient? Because beta-sitosterol is not an essential nutrient, deficiencies do not occur.

How much is usually taken? Between 500 mg and 10 grams of beta-sitosterol per day have been used in clinical research to reduce elevated blood cholesterol levels. Between 60 (20 mg three times per day) and 130 mg per day have been used in trials reporting a reduction in prostatic hyperplasia-related symptoms.8 9

Are there any side effects or interactions? No significant side effects or interactions have yet been reported in studies on beta-sitosterol.

At the time of writing, there were no well-known drug interactions with beta-sitosterol.
