Super metformin

Metformin has been a primary drug gainst diabetes for more than 50 years.
Studies show that metformin acts by boosting the activity of AMPK, a master metabolic regulator that favors fat- and sugar-burning and prevents their accumulation.
Because AMPK is relevant in all tissues, this makes metformin extremely important in reducing metabolic imbalances in the entire body.
Strong evidence suggests that metformin, through its protective effects and AMPK-activating properties, can help prevent cancer, cardiovascular disease, obesity and its consequences, and even neurodegenerative disorders.

Studies show that metformin fights obesity and reduces body fat mass, even in non-diabetic patients.
