Seeking Health Optimal PC provides phosphatidylcholine (PC) — the primary phospholipid component of cell membranes — from sunflower lecithin in highly bioavailable softgel form. PC supports brain cell membrane integrity, liver health, bile flow, methylation and healthy acetylcholine levels.

Frequently Asked Questions

What is phosphatidylcholine and why is it important?

Phosphatidylcholine (PC) is the most abundant phospholipid in human cell membranes, making up approximately 50% of the cell membrane bilayer. It is essential for maintaining membrane fluidity, cellular communication, liver fat metabolism, bile production and acetylcholine neurotransmitter synthesis.

How does Optimal PC support liver health?

The liver requires phosphatidylcholine for healthy fat metabolism and to prevent fatty liver (NAFLD). PC supports bile phospholipid content, essential for bile flow and the emulsification of dietary fats. Deficiency is associated with increased liver fat accumulation.

Is Optimal PC derived from soy or sunflower?

Optimal PC is derived from non-GMO sunflower lecithin, making it suitable for those avoiding soy. Sunflower-derived PC is considered a clean alternative with equivalent phosphatidylcholine content to soy-derived sources.

Who should consider Optimal PC?

Those with liver conditions or fatty liver, those wanting to support brain health and cognitive function, those with bile insufficiency, athletes wanting to support cell membrane integrity, and those following high-fat or ketogenic diets.
