The Tight Review

Bioperine- Basically a pure and safe nutritional supplement of piperine, Bioperine can have several positive effects on our body. It contains about ninety five percent of piperine that is known to enhance the bioavailability of nutrients. As a result, bioperine intake helps in rapid absorption of nutrients from the gastrointestinal tract. Owing to its affinity for the fatty tissue, it even interacts with the lipid component of the intestinal cell membrane thereby allowing further nutrient permeability. It is quite popular due to its ability to enhance thermogenesis. This is how it works - the piperine present in bioperine stimulates the release of catecbolamines that trigger thermogenesis in the GI tract thus, making more energy available for digestion. It can be combined with other nutrients too to improve the health of human beings as well as animals.

Caffeine is a stimulant drug used for mental alertness and to accelerate energy and power. It is also used to delay muscle fatigue as it goes deep into the muscle tissues.

Green Tea Extract is very popular with the health conscious community, mainly because of the broad antioxidant features, which are provided by the green tea catechins. It is a very popular nutritional supplement, much more popular than regular green tea, because several green tea extract products have no caffeine. Caffeine is actually contained in larger quantities in green tea than in coffee. Besides the already mentioned catechins, further polyphenols are included in the Asian tea favorite. Green tea furthermore contains carotenoids, ascorbic acid – more commonly known as Vitamin C, Minerals and tocopherols. While there are many proven qualities of green tea extracts, some lesser researched effects have been observed, like reduction of LDL cholesterol, increasing the levels of norepinephrine, weight loss and additional antioxidant qualities.

Sclareolide is a terpenoid, similar to sclareol, which is a plant antifungal compound. It has been used widely in the cosmetics industry but has been recently rediscovered as a thermogenic supplement. It is deemed actually a weight loss aid, whereby it is supposed to increase energy consumption by turning it into heat. While it is not only a weight loss supplement, but also an energy supplement, it is not really a new product. It is an alternative to ephedra, which has been banned. While sclareolide is new, it has been widely touted as the safe and healthy alternative to ephedra. Also named normabrolide, this cAMP activator is currently derived from extracts of the clary sage herb and is deemed to help athletes achieve the lean, shredded look.

Synephrine, More commonly called "bitter orange" or Citrus Aurantium, which is taken from unripe oranges. Research shows that citrus aurantium can increase the metabolic rate without affecting heart rate or blood pressure, breaks down fat, burns calories and may act as an appetite suppressant.

Synthetic Guggulsterones, which is a form of orally administered guggulipid, which increases T3 (tryiidothyronine) levels in animal models. T3 is the conversion product of T4, which is produced by the thyroid gland. Thyroid hormone levels are closely involved in metabolic function. Increased thyroid levels can cause more fat to be burned and stored. While on a diet, the body responds by decreasing T3 levels, therefor decreasing metabolic rate. It is not known how guggulipid increases T3 levels. Guggul, also called guggulipid, is an ethyl acetate extract of the gum resin of the guggul tree.

Vinpocetine is a derivitate of the periwinkle plant and was developed in the latter part of the 1960’s. It can be used as a dietary supplement, which can be found online.

Yohimbe- Basically a tree bark, Yohimbe is rich in pharmacologically active chemicals. It is commonly found in products developed for body building and enhancing male performance. The use of Yohimbe causes serious side effects too that include renal failure, seizures and in very rare cases, even death. Individuals suffering from low blood pressure, heart disease, liver or kidney disease, and diabetes should refrain from using any kind of Yohimbe supplements. Taking larger doses of Yohimbe can cause weakness, stomach disorders, fatigue, and nervous stimulation followed by paralysis. It is therefore important to avoid self-medication. Sometimes, side effects may arise even if small amounts of this supplement are taken, especially for prolonged periods. If you are already taking drugs for treating some health condition, it is best to avoid this supplement.
