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.

A study has proven that a combination of yerba mate, guarana and damiana leads to a tenfold weight loss quantity when compared with a placebo.

Inositol named as “myo inositol” is a nutrient that is considered to occur naturally and considered as “carbocyclic polyol”. One of the major advantage that inositol has is the prevention of fat formation around the liver. It is also good to promote healthy, thick hair growth.

It is commonly found in breast milk, red meat and dairy products. Low levels of L Carnitine can cause cramps in the muscles, low blood sugar and tiredness. When using supplements of L-Carnitine, a person must use suitable amounts of Vitamins C and B, along with iron supplements. Proteins from animals and other foods, rich in nutrition will assist in meeting the required levels of nutrition.

L-Tyrosine is a proteinogenic polar amino acid, deemed not essential because it can be synthesized by the human body. As a member of the amino acid group that is being used by cells to build proteins, this building block derived its name from the Greek word tyros, which means cheese, because it was discovered in the cheese protein casein. L-Tyrosine can be synthesized from phenylalanine and can be found in foods high on protein, like soy products, poultry, cheese, bananas, dairy products and several seeds, including the sesame seeds. The unique phenol functionality and the occurrence in proteins that belong to the signal transduction process, make this amino acid different. Tyrosine can be converted by tyrosine hydroxylase enzyme into levodopa, a psychoactive drug that is used, among other uses, for clinical treatment of Parkinson’s disease. It is also involved in the synthesis of dopamine, norepinephrine and epinephrine.
