Choline
Essential for your liver, brain, and every cell membrane.
~90% of Americans do not meet the adequate intake for choline
Why it matters for longevity
Choline is a precursor to acetylcholine (a neurotransmitter critical for memory), phosphatidylcholine (the primary component of cell membranes), and betaine (important for methylation and liver health). Inadequate choline intake accelerates liver fat accumulation and is linked to cognitive decline. Despite its importance, choline was only recognized as an essential nutrient by the IOM in 1998.
