Testosterone Booster Reviews

Natural Sterol Complex (By Universal Nutrition)

By  | 

Natural Sterol Complex is an “advanced ultra-concentrated anabolic formula”. According to Universal Nutrition, Natural Sterol Complex is a powerful alternative for bodybuilders and it contains “eight distinct and important components”.

Containing plant sterols, energy substrates, amino acids, electrolytes, essential fatty acids, performance boosters, and important minerals, Natural Sterol Complex is presented as something really different.

Let’s find out…

Natural-Sterol-Complex

Natural Sterol Complex by Universal Nutrition Nutrient Profile

Anabolic Sterol Complex (2,000 mg)

  1. Beta Stosteroi (Stigmasterol; Fucostetol; Campesterol Mixed Sterols), starting with stigmasterol, considered to be a precursor to the manufacture of semi-synthetic progesterone, the vital hormone required for regulating tissue rebuilding, and the biosynthesis of corticoids estrogens, and androgens. Fucostetol is a type of sterol “isolated from algae with anti-diabetic activity such as Ecklonia cava”. And finally, Campesterol is a naturally occurring nutritional element that has a similar composition to cholesterol, and at present there is very little information available.
  2. Tribulus Terrestris is a type of herb belonging to the Ayurveda family. Its roots in fruits have long been used to help promote male virility and vitality. It is believed to possess libido enhancing properties, but in terms of interaction with hormones including testosterone, there appear to be very little.
  3. Kudzu is a type of Root plant that is traditional uses included helping to alleviate hangovers and even migraines. In terms of studies, there is nothing concrete to suggest that kuzdu is effective in performing any particular function.
  4. Methoxyisoflavone is a synthetic chemical compound marketed as a bodybuilding supplement. At present, there is absolutely no clinical evidence to support this suggestion.
  5. Beta Ecdysterone is a type of popular ecdysteroid that is known to be anabolic in its nature. In terms of trials, there is not much information available at present.
  6. 5,7 Dihydroxyflavone is a synthetic flavonoid that is known to interact with the brain and activate the TrkB receptor that is known to promote neuronal growth. Thus far, all trials seem to be animal-based, and no human evidence is available.

Mass and Density Blend (2,500 mg)

  1. Muria Puama is a traditional aphrodisiac and nerve tonic, commonly associated with the region of Brazil. At present, there are no bonafide human trials, but in preliminary rat studies, it has shown to enhance cognition and little else.
  2. Stinging Nettle Root, although a horrid plant to touch, oral ingestion in the form of pills seems to help suppress inflammation, as well as help to reduce sniffles. Despite widespread claims, stinging nettle root does not affect testosterone. Take this study as an example, where 558 male subjects were administered with a 120 mg of stinging nettle root three times daily for a period of six months. Researchers did not find any major differences between the supplemented group and the placebo group.
  3. Oriental Ginseng belongs to the ginseng family and is known to be effective in helping to enhance cognition, immunity, overall mood, as well as possessing pro-erectile, pro-testosterone, and pro performance properties. Here is an example of one study, where ginseng managed to enhance testosterone and DHT, but not prolactin. An important point to note is that the subjects were men with poor sperm mortality.
  4. Kola Nut is a traditional medicine commonly used to help enhance cognition. According to one study involving 33 subjects of both genders were administered with 1000 mg daily for 60 days and researchers noticed reduced symptoms of anxiety, and increase in attention.
  5. Cissus Quadrangularis has long been used in traditional medicine to aid joint and bone health amongst other things. Preliminary testing seems to suggest it may promote bone growth rates, and as a result, it is fast becoming a joint aid for athletes.
  6. White Button Mushroom has been used in traditional medicine for thousands of years, but only recently, Western medicine has began to look at this fungi in great detail. White button mushrooms are packed with nutrients including B vitamins, digestive enzymes, vitamin D2, and even protein. In terms of studies looking in detail at the full potential of White button mushroom, there is very little out there.
  7. Gymnema Sylvestre referred to the leaves of the plant that has traditionally been used to treat diabetes mellitus, and obesity. At present, although widely used in health supplements, there are very little studies available to showcase its full potential.
  8. Eurycoma Longifolia is a recognized aphrodisiac and pro fertility agent, and some trials seem to point to estrogen suppression and pro-erectile properties. Despite many claims, there is no evidence to suggest any interaction with testosterone, other than trivial spikes in infertile men, as seen here.
  9. Guarana is a type of seed that is known to contain more caffeine than coffee beans; hence it’s usually used in stimulatory products including supplements such as fat burners.

Opti-Phytonutrient Complex (2,000 mg)

  1. Alfalfa is packed with natural minerals and vitamins including A, D, E, K, as well as calcium, folic acid, biotin, and B vitamins, alongside potassium, magnesium and iron. Alfalfa also contains high levels of protein when in dried form.
  2. Milk Thistle Root is a type of herb that contains a number of active ingredients known as Silymarins. It is believed to be therapeutic to the liver if supplemented regularly.
  3. Spirulina is a type of algae that’s not known to be toxic. Investigations seem to suggest that Spirulina is extremely effective in helping to protect the brain, as well as reducing liver fat.
  4. Dandelion Root’s traditional uses include helping to alleviate gastrointestinal ailments. According to some suggestions, dandelion supplementation may encourage food to exit the stomach faster, but more evidence is needed in this regard.
  5. Garlic is a type of vegetable believed to promote cardiovascular health, as well as helping to enhance immunity.
  6. Ginger Root is traditionally used in cooking as well as medicine, including Ayurveda and Chinese medicine.  Studies have suggested that even small doses (1-3 g) can aid digestion, and may even increase testosterone, as seen here.
  7. Licorice Root, derived from licorice, a common name for a plant belonging to the Glycyrrhiza family, and is suspected of decreasing testosterone, whilst increasing cortisol, as illustrated by this study..
  8. Wheat Grass is packed with magnesium, calcium, vitamin E, vitamin C, Vitamin A and chlorophyll.
  9. Saw Palmetto Root is a fatty acid mix that is often touted to be an effective testosterone enhancer. Unfortunately, studies don’t seem to substantiate this, click here to see more.
  10. Celery Seed contains a high amount of volatile compounds known as phthalides. These compounds are known to be highly anti-oxidative as well as diuretic.
  11. Cayenne offers many benefits including anti-irritant properties, anti-cold/flu effects, anti-fungal properties, headache prevention, digestion aid, anti-allergen, pro-digestion benefits among many other things.
  12. Chlorella is a type of freshwater algae that’s believed to be rich in iron and vitamin B12.

EFA Complex & Support Blend (From Flaxseed Powder, Lecithin) (500 mg)

  1. Alpha-Linolenic Acid is a type of fatty acid that interacts with energy metabolism. Alpha-Linolenic Acid is believed to provide a short-lived potent reduction in oxidation, and anti-oxidant enzymes. It is also suspected of helping to reduce blood glucose.
  2. Oleic Acid aka omega-9 is a monounsaturated fatty acid that is known to improve insulin sensitivity and blood circulation among other things.
  3. Palmitic Acid is a saturated fatty acid that can be found in animals as well as plants. Palmatic acid, when taken in moderation is antioxidant, and anti-atherosclerotic, as demonstrated in animal studies. However, when taken in larger amounts, it can increase the risk of developing cardiovascular diseases.  Thanks to the proprietary blend, we just don’t know how much this supplement contains.
  4. Stearic Acid is a saturated fatty acid commonly used in shampoos, detergents, soaps and shaving creams.
  5. Phosphatidylethanolamine are a class of phospholipids usually found in biological membranes, and in humans, it plays a role in lipoproteins secretion in the liver.
  6. Phosphatidylcholine is a type of phospholipid attached with a choline usually found in soy lecithin.

Muscle Cell Protection Blend (500 mg)

  1. Green Tea Leaf contains high levels of green tea catechins commonly used in weight loss supplements.
  2. Ginkgo Biloba Leaf is a type of herb commonly taken in traditional medicine to promote brain health. It is thought it might possess cognitive enhancing properties, but existing results seem to be unreliable.
  3. Citrus Bioflavonoids are a class of nutrients collectively referred to as “Vitamin P”.
  4. Grapeseed Extract contains chains of catechins that seem to possess anti-estrogenic effects, and may also be effective in enhancing the blood flow.
  5. Lycopene is a powerful antioxidant even though human trials have delivered a mixed bag of results.

Effectiveness

I honestly wouldn’t know where to begin when looking at just how effective Natural Sterol Complex really is. The majority of the ingredients are hidden behind proprietary blends, so there’s no way of knowing whether they are sufficiently dosed.

Most of the ingredients in Natural Sterol Complex I have not seen before (if I’m frankly honest).

A lot of the ingredients don’t really have any studies to back them, so you have to take Universal Nutrition’s word for it!

How to Take Natural Sterol Complex by Universal Nutrition

Take 6 tablets every day, 2 immediately after your meals.

Side Effects

Nervousness and anxiety are two common symptoms associated with Natural Sterol Complex.

Cost

You can buy a 90 tablet container for $12.18 or a 180 tablet container for $22.42.

Natural Sterol Complex by Universal Nutrition Overall Rating

I really believe Natural Sterol Complex must be underdosed because for $12.18 for a 90 tablet container, I don’t see how Universal Nutrition could be making a profit!

There’s no way of establishing how effective the ingredients are, because their precise amounts are not disclosed due to the proprietary blends. This fact alone is a major concern for me because with ingredients like Palmitic Acid, that require close supervision because if it’s overdosed for whatever reason, can increase the risk of developing cardiovascular diseases.

Moreover, I think Universal Nutrition have mushed together as many ingredients as possible into one supplement, without giving consideration to any potential allergies that users may have.

On the whole, I’m very disappointed!
