The Meyers Cocktail, an original mixture of orthomolecular infusion therapies, was developed in the 1950s by Dr. John Myers, an American physician. This therapy involves the administration of high-dose vitamins (such as vitamin C and B vitamins) and minerals (such as calcium and magnesium) to treat exhaustion, chronic fatigue, reduced performance, during convalescence after illness, or simply to increase well-being and performance. A traditional Meyers Cocktail contains high-dose vitamin C, B vitamins (thiamine, riboflavin, niacin, panthenol, pyridoxine, biotin, folic acid, cobalamin), magnesium, and calcium in a carrier infusion solution. Over time, other proven formulations and infusion mixtures based on the Myers Cocktail have been developed for various indications, also containing amino acids and antioxidants. For a sustained effect, 10-12 infusions at weekly intervals are usually recommended. The infusion takes about one and a half hours in total, with the folic acid being added separately for compatibility reasons.
