A safe and effective dose for soy lecithin has not been determined yet. Since soy lecithin is a dietary supplement, only vague "trial and error" dosing information is available. Clinical studies have used doses ranging from 3.6 grams twice daily (to enhance athletic performance), 30 to 50 grams daily (to treat tardive dyskinesia), to 10 mg three times daily (to treat bipolar mania).

Soy Lecithin Dosage: An Introduction

It is difficult to recommend a dose for soy lecithin that is safe and effective. As is common with dietary supplements, the best doses for this product have not been scientifically established yet.

What Is a Reasonable Dose of Soy Lecithin?

Only vague "trial and error" dosing information is available for soy lecithin. Even if good dosing information was 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.
One study of lecithin to enhance athletic performance used a soy lecithin dose of 3.6 grams 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 lecithin 10 mg three times daily.
Since different soy lecithin supplements may contain different amounts of the active components, it is reasonable to follow the dosage instructions provided on the label of your particular product.

General Information on Your Soy Lecithin Dosage

Some considerations for people taking soy lecithin include the following:
  • If you have any chronic health problems or take any prescription medications, it is a good idea to check with your healthcare provider before taking soy lecithin.
  • Since the manufacturing of supplements is not closely regulated, it is important to choose a trustworthy manufacturer of your soy lecithin supplements. It is a good idea to look for the "USP" symbol, since this means that the supplement meets certain standards, such as standards for purity.
  • If you are unsure about anything related to your dosage or soy lecithin dosing in general, please talk with your healthcare provider or pharmacist.
