Sunflower Lecithin

Fatty acidphospholipidLimited dose evidence

Also known as: lecithin, sunflower phosphatidylcholine, phospholipid complex, Helianthus annuus lecithin, deoiled sunflower lecithin

Add to a formula

Sunflower lecithin is a mixture of phospholipids, chiefly phosphatidylcholine, phosphatidylinositol, and phosphatidylethanolamine, separated from sunflower oil during degumming. It is the soy-free alternative to soy lecithin and is sold as a viscous liquid or a deoiled powder. In supplements it serves both as a source of phosphatidylcholine (and therefore choline) and as an emulsifier that helps disperse oils in powders and liquids. Human dosing data come mostly from soy lecithin trials, which used similar phosphatidylcholine-rich material.

Research summary

Phosphatidylcholine supplies choline for acetylcholine and membrane phospholipid synthesis and acts as a surfactant that aids fat emulsification in the gut.

Dosage

Daily amounts, of compound.

Lowest studiedTypical rangeHighest studiedUpper limit
500 mg1,200–2,400 mg——

Dosed as mg lecithin. A soy lecithin trial used one 500 mg capsule daily (basis for dose_min); a marathon study gave about 2.2 g lecithin per day supplying roughly 1.1 g choline, the highest trial dose located, which sits below the 2,400 mg market high, so dose_max_studied is left null. Sunflower lecithin evidence is extrapolated from soy lecithin, and the typical 1,200-2,400 mg range reflects common product servings rather than a trial-defined optimum. Phosphatidylcholine content varies from about 20% in crude liquid lecithin to higher in deoiled or PC-enriched grades; check the CoA when a choline figure is stated.

Standardization: Declare phosphatidylcholine % (crude liquid about 20-25%; deoiled powder higher; PC-enriched grades to 35% or more)

Source material: sunflower oil degumming gums, deoiled or liquid

As supplied: Choline yield depends on phosphatidylcholine grade; roughly 13% of the phosphatidylcholine mass is choline

Format suitability

  • Capsule
  • Powder
  • Tablet
  • Softgel
  • Gummy
  • Liquid

Liquid lecithin fills softgels (1,200 mg is a standard size) and blends into liquids. Deoiled powder works in powders and capsules and doubles as a dispersing agent for oily actives. Bulk density listed is for the liquid; deoiled powder is much lighter (verify supplier sheet).

Formulation notes

Soy-free, which is its main reason for use; soy lecithin would carry the soy allergen flag. Sunflower is not a major FDA allergen. Contributes choline toward any choline total in the formula.
