Phosphatidylcholine (PC) is a major phospholipid in cell membranes and a key component of lecithin. It plays a vital role in cell structure, signaling, and repair, and is an important choline source for neurotransmitter synthesis.
Key benefits include:
Supports brain function and memory by providing choline for acetylcholine synthesis
Promotes liver health by enhancing lipid metabolism and protecting hepatocytes
Improves cell membrane fluidity and nutrient transport
Supports skin health by improving barrier function
High-purity extraction from non-GMO soy lecithin or sunflower lecithin
Gentle processing to preserve bioactivity
GMP & ISO certified production
Bulk supply capability for global OEM/ODM
Meets USP/EP quality standards

Q: Can you take phosphatidylcholine every day?
A: Yes, daily use is common and safe for most people. Phosphatidylcholine is a vital nutrient that your body uses continuously to build cell membranes and support brain function. Consistent daily intake helps maintain optimal levels.
Q: What is the risk of phosphatidylcholine?
A: It is generally very safe. High doses (well above 3,000 mg) may cause minor, temporary side effects like stomach upset, diarrhea, or sweating. As it can be metabolized into TMAO (a compound linked to heart risk in some studies), individuals with existing cardiovascular issues should consult a doctor before using high-dose supplements.
Q: What foods contain phosphatidylcholine?
A: It is abundant in many whole foods. The richest sources include:
Egg Yolks (especially raw or lightly cooked)
Organ Meats (like liver)
Soybeans and Soy Lecithin
Sunflower Lecithin
Cruciferous Vegetables (like broccoli and Brussels sprouts)
Lean Red Meat
Fish Roe (Caviar)
Q: Does phosphatidylcholine help with sleep?
A: It can indirectly support healthy sleep. As a precursor to acetylcholine (a neurotransmitter that regulates sleep cycles), it may help promote a normal sleep-wake rhythm. Its primary benefit for sleep lies in its role of supporting overall brain health and calming nervous system function, rather than acting as a direct sleep aid.
