These therapies are safe and effective for most people. Myer’s cocktails are a specific blend of B complex, B5, B6, B12, vitamin C and magnesium. This IV treatment is administered by a "drip" that takes 30-40 mins. These IVs often provide patients with more energy and a kick start to the metabolism. A Myers cocktail also helps to increase stamina and performance in athletic pursuits. Older patients and chronically ill patients with nutritional deficiencies and compromised intestinal absorption often find great benefit from this therapy.
