Caffeine is of course a major component of every day drinks such as tea and coffee and is also included in RedLine.

Evodiamine has been used in Chinese medicine and by Chinese herbalists for centuries for weight loss purposes. It is an extract from a plant, Evodia or Tetradium, actually a tree genus of the family Rutaceae. The bee bee tree, as it is called besides Euodia and Evodia, provide a bioactive alkaloid that the Chinese have nicknamed Wu-Chu-Yu. This extract not only can interact with UCP1, a thermogenic protein, which as a consequence burns energy as heat, but also has shown in studies on mice to reduce the fat uptake. Evodiamine seems to increase the resting temperature of humans, whereby increased fat and calories are burned in order to supply the heat. Deemed a breakthrough in thermogenesis, evodiamine is subject of several clinical studies.

Green Tea Extract increases energy expenditure and affects fat oxidation, which therefore promotes weight loss by increasing the body's metabolism.

L-Tyrosine is an amino acid that is nonessential. It is synthesized from the body from phenylalanine which is also an amino acid. L-Tyrosine has the power to have an effect on the neurotransmitters and this affects various health conditions including depression, mood disorders and Parkinson’s disease. Many such studies have proved that L-Tyrosine helps people having depression. It acts as a precursor and eases the effects of psychosocial, environmental and physical stress.

The thyroid hormones playing a significant role in the process of the body also contain tyrosine.

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, a memory enhancer. Vinpocetine makes cerebral microcirculation (blood flow) easier, increases brain cell ATP production, and increases useability of glucose and oxygen.

Yerba Matte- The plant of the yerba maté, as yerba matte is actually called, is a small tree or a shrub which can grow up to a size of fifteen meters. The leaves and twigs have traditionally been used to brew a tea like concoction, which is still a very popular social beverage in South America. Yerba maté contains alcaloids that are very similar to caffeine, commonly referred to as xanthines, but also elements like manganese, magnesium and potassium. The main difference between yerba maté and coffee, for instance, is the effect it has on muscle tissue, where it appears to relax smooth muscle tissue, but stimulate heart tissue and that is why it is used in RedLine. In other studies, yerba maté was found to work as a monoamine oxidase inhibitor, thereby professing antidepressant qualities.
