✓ What the Science Says
Choline is an essential nutrient that plays a critical role in brain health, particularly in the synthesis of acetylcholine, a neurotransmitter involved in memory and muscle control. It has been shown to support cognitive function and may contribute to improved memory performance, especially in populations with low dietary intake.
✗ What It Doesn't Do
Choline is often marketed as a miracle supplement for weight loss or extreme cognitive enhancement, but there is no strong evidence to support these claims. It does not replace a balanced diet or serve as a substitute for other essential nutrients.
