Is intravenous vitamin therapy useful?

Intravenous vitamin therapy, such as Myers' cocktail, is a treatment in which vitamins and minerals are administered directly into the bloodstream.

The Myers' cocktail is named after Dr. John Myers, who developed this blend of vitamins and minerals. The cocktail usually contains a combination of magnesium, calcium, B vitamins (such as B12, B6, B5 and B complex) and vitamin C.

Some report benefits in treating chronic conditions such as fibromyalgia, chronic fatigue, migraines, and muscle cramps. It is also claimed that it can improve immune function, which can be helpful for people with frequent infections.

Many patients report an increased feeling of energy and overall well-being after therapy. Athletes sometimes use this therapy for improved performance and faster recovery after intense workouts.

The scientific evidence for the effectiveness of the Myers' cocktail is limited and largely anecdotal. There are some small studies and many case reports reporting benefits, but large-scale, placebo-controlled studies are lacking. The scientific evidence is not yet convincing enough to generally recommend its use.

There are side effects with intravenous administration such as infection at the injection site, allergic reactions and electrolyte disturbances.
