A thermogenic is a broad term for any supplement that the manufacturer claims will cause thermogenesis , resulting in increased body temperature, increased metabolic rate, and consequently an increased rate in the burning of body fat and weight loss.
Until almost every product found in this supplement category comprised the " ECA stack ": However, on February 6, the Food and Drug Administration FDA banned the sale of ephedra and its alkaloid , ephedrine, for use in weight loss formulas.

The utility of HMB does seem to be affected by timing of intake prior to workouts and dosage . Experimental models, fatty infiltrations, and prevention".
In conclusion, HMB treatment clearly appears to be a safe potent strategy against sarcopenia, and more generally against muscle wasting, because HMB improves muscle mass, muscle strength, and physical performance. It seems that HMB is able to act on three of the four major mechanisms involved in muscle deconditioning protein turnover, apoptosis, and the regenerative process , whereas it is hypothesized to strongly affect the fourth mitochondrial dynamics and functions.
For all these reasons, HMB should be routinely used in muscle-wasting conditions especially in aged people. HMB, a derivative of leucine, prevents muscle damage and increases muscle strength by reducing exercise-induced proteolysis in muscles and also helps in increasing lean body mass. The meta analysis studies and the individual studies conducted support the use of HMB as an effective aid to increase body strength, body composition, and to prevent muscle damage during resistance training.
