Caffeine is a bitter, white crystalline xanthine alkaloid that acts as a stimulant drug and a reversible acetylcholinesterase inhibitor.
Caffeine is found in varying quantities in the seeds, leaves, and fruit of some plants.
It is most commonly consumed by humans in infusions extracted from the seed of the coffee plant and the leaves of the tea bush, as well as from various foods and drinks containing products derived from the kola nut.
Beverages containing caffeine, such as coffee, tea, soft drinks, and energy drinks, enjoy great popularity.
Taurine has antioxidant properties – Taurine acts like an antioxidant to fight off free radicals and to protect the body’s cells from damage from oxidation.
Taurine can also reduce the effects of hypertension, or high blood pressure, and can increase the exercise capacity of those who have congestive heart failure.
Taurine supplements can reduce the risk of hyperglycemia and insulin resistance.
Taurine is also contained in different foodstuffs like scallops, fish, poultry and most baby food. Taurine is involved in vital functions of the human body. It acts as a detoxifying agent by binding with harmful substances and thereby accelerating their excretion from the body.
Guarana features large leaves and clusters of flowers, and is best known for its fruit, which is about the size of a coffee bean.
As a dietary supplement, guarana is an effective stimulant: its seeds contain about twice the concentration of caffeine found in coffee beans (about 2–4.5% caffeine in guarana seeds compared to 1–2% for coffee beans).
The guarana fruit's colour ranges from brown to red and contains black seeds which are partly covered by white arils.
B vitamins are a group of water-soluble vitamins that play important roles in cell metabolism. The B vitamins were once thought to be a single vitamin, referred to as vitamin B.
All B vitamins are water-soluble, and are dispersed throughout the body. Most of the B vitamins must be replenished regularly, since any excess is lost naturally.
Processed carbohydrates such as sugar and white flour tend to have lower B vitamin than their unprocessed counterparts.
B vitamins are particularly concentrated in meat such as turkey and tuna, in liver and meat products.
