Lecithin Dosage

A safe and effective lecithin dosage has not been established. As with most dietary supplements, only vague "trial and error" information is available for lecithin. Doses of 20 to 50 grams have been used in studies for treating tardive dyskinesia, and one study used 10 mg three times daily to treat bipolar mania. It is best to follow the dosing directions on your particular product.

An Introduction to Lecithin Dosage

It is difficult to recommend a safe and effective dosage for lecithin. The best doses for lecithin have not been scientifically established yet, as is common with dietary supplements.

Reasonable Lecithin Dosing

Because dietary supplements do not need to be approved by the FDA, studies to find the safest and most effective dosages for dietary supplements are rarely performed. Without such studies, typically, only vague "trial and error" information is available. Even if good dosing information were available, there may be significant variability of the content, purity, and strength between different brands of the same dietary supplement, making consistently safe and effective dosing difficult. With lecithin, the source (egg or soy) can significantly affect the composition of the supplement, leading to further problems recommending a lecithin dosage.
One study of lecithin to enhance athletic performance used a dose of 3.6 grams of lecithin twice daily. To treat tardive dyskinesia (a movement disorder caused by certain medications), a dose of 20 to 50 grams a day has been used in studies. To treat bipolar mania, one study used 10 mg of lecithin three times daily.
Since different lecithin supplements may contain different amounts of the active components, it is reasonable to follow the dosing instructions provided on the label of your particular product.
