These are the herbal caffeine you often see added to sports drinks, and drinks like Monster Energy. The herbal caffeine is called Guarana. The pills contain the powder. The strength and amount of caffeine in the pills can vary by manufacturer. The best ones will contain about 100mg of caffeine per pill, which is about 2/3rds the caffeine in a regular cup of coffee.

CLA has several impressive properties. It is anti-inflammatory, it is a partitioning agent that directs calories to muscle rather than fat cells, and it is an antioxidant. It is synergistic with Guarana (a source of caffeine) and the combination reduced fat cell volume and numbers of fat cells by 50% in a study of obese mice. Sesame lignans help prevent excess epidymal and perineal fat in combination with CLA.
