What Is Natural Sterol Complex?

Natural Sterol Complex is a supplement made of Natural Testosterone Boosters, including plant sterols from various ingredients such as Tribulus Terrestris and Muria Puama. Plant sterols, which are a type of phytosterols, are substances that naturally occur in many plant sources, and Natural Sterol Complex contains 2500 milligrams of these powerful actors. This all-natural, plant-based supplement works to increase an athlete’s own production and retention of naturally produced testosterone, which in turn leads to increases in muscle mass, strength, energy, and stamina.

In this complete supplement over 40 different ingredients work together to help bodybuilders and other athletes achieve better results from their regular workouts. These ingredients include herbal energy boosters such as Oriental Ginseng, Guarana, and Kola Nut, which work quickly to encourage working out harder. Other ingredients, including Spirulina, Wheat Grass, and Saw Palmetto Root, work to speed healing and recovery and promote overall health.

Users are instructed to take two capsules three times a day, either with meals or 15 minutes before working out. While the supplement will increase energy right away, users report seeing real results after about 4 weeks of use. With regular use, users report an increase in strength, leading to gains in muscle mass and overall fitness.



The manufacturer of Natural Sterol Complex is Universal Nutrition, an American-based company that specializes in sports nutrition for bodybuilders and other athletes. Universal Nutrition was formed in 1977 and has consistently manufactured and produced their supplements in the United States. They currently operate in multiple states across the country, including 100,000 square feet of state-of-the-art facilities where they research and produce all of their own supplements. Because they employ their own researchers and manufacturers, they are able to guarantee the purity and high quality of all the ingredients used in their products. The company also can create products that respond directly to the requests of customers, such as their Low Carb line.

Universal Nutrition sells their many sports nutrition products both in retail locations and through various reliable online distributors. Their products, especially those designed to be used by bodybuilders, have received very positive reviews online across a number of websites. They also have a robust social media presence, with accounts on Facebook, Twitter, and Instagram. Since Universal Nutrition has been in business for over 35 years, they have a strong standing and reputation of credibility in the bodybuilding community.


How Natural Sterol Complex Works?

A single serving of Natural Sterol Complex is 6 capsules, which should be taken throughout the day, usually with meals. For athletes who are working out, it is recommended that they add another two capsules before each workout. This can end up being a large number of capsules, but the ingredients are all-natural and therefore purportedly safe.

The ingredients in Natural Sterol Complex work together in a number of ways to increase muscle gains, naturally boost testosterone, add energy, and aid in recovery. Each capsule contains over 40 ingredients blended together to achieve maximum impact. While the Natural Testosterone Boosters, including Tribulus Terrestris, stimulate natural testosterone production and retention, the proprietary Mass and Density Blend works to increase muscle mass and strength.

While users often experience an initial energy boost, the results will increase with continued use over a couple of months. This is especially true when the increase in energy and stamina leads to an increase in the number and strenuousness of workouts. Users report seeing results after about a month of use, especially when taken regularly as recommended.


Ingredients of Natural Sterol Complex

A serving of Natural Sterol Complex is made of 5 different proprietary, plant-based blends, designed to work together for maximum results. The first listed blend is the Anabolic Sterol Complex, made of natural plant sterols, including the famed bodybuilding supplement Tribulus Terrestris. This, along with other plant-based ingredients such as Beta Stosteroi, Methoxyisoflavone, and 5,7 Dihydroxyflavone, works to stimulate Natural Testosterone Boosters inside the body.

The next listed blend is the Mass and Density Blend, which contains evidence-based all-natural herbal ingredients. Some of the familiar herbs in this blend include Muria Puama, Oriental Ginseng, and Guarana, which all have proven energy boosting properties. This is complemented by the Opti-Phytonutrient Complex blend, which contains multiple sources of herbal support such as Milk Thistle Root, Saw Palmetto Root, Garlic, Chlorella, Cayenne, and Licorice Root.

The FA Complex & Support Blend provides 500 milligrams of natural amino acids, derived from Flax Seed and Lecithin. Finally, the FA Complex & Support Blend contains herbs and extracts that support healing and overall health, including Green Tea Leaf, Grapeseed Extract and Ginkgo Biloba Leaf. This supplement is appropriate for vegan and gluten free diets, and the lecithin is derived from soy.



The greatest advantage of Natural Sterol Complex is that it is a complete supplement, which contains a vast, diverse array of ingredients. While many supplements contain just one or a handful of ingredients, Natural Sterol Complex contains over 40 proven ingredients, designed to work together for the best results. Athletes can use this supplement and not have to worry about mixing and matching to get good results.

Another advantage to this supplement is that it is derived from all natural, plant-based ingredients. The well-known, Natural Testosterone Boosters are all from herbal ingredients and other organic sources. The all-natural plant sterols, including Tribulus Terrestris, herbal energy boosters, amino acids, electrolytes, fatty acids, and other ingredients are all proven to be safe and efficacious.

Finally, this product has the advantage of a positive track record among athletes who have used it in the past, including some long term use. The combination of ingredients work together to get optimum results as long as users continue to work out while taking them. Athletes report that they work out more when using this supplement, which means they get even faster results.

This stuff is amazing! I used it a while back and saw great results, but then I took some time off to focus on other fitness goals. I saw myself losing ground so I bought another couple bottles and within a couple of weeks I was back on track. More energy and fast results!

– Mike H., Columbus, IN

I like this for bulking up fast without a bunch of side effects or nonsense. It gives me energy without making me nervous or on edge. And it helps me gain mass without gaining fat. I been using for like 3 months and aren’t going to stop.

– Tom R., Washington, DC

Natural Sterol Complex has worked great. I don’t really like taking 6 pills every day, but I can’t argue with the results. I’ve gained muscle, I can work out harder and more often, and I don’t get tired after lifting. I guess I’ll put up with the inconvenience of the pills so I can get the results!

– Bill C., San Francisco, CA

I heard about this a while ago from a pro that I met at the gym. He said it was good stuff and I agree! All natural so I know it’s healthy, I got more muscle now than when I started for sure. I also like that it’s easy to remember and I don’t have to shop around or take a bunch of different things.

– Ken F., San Antonio, TX
