Alpha-GPC (alpha-glycerophosphocholine or choline alphoscerate) is a choline-containing phospholipid. When ingested, alpha-GPC is metabolized into choline and glycerol-1-phosphate. Choline is a precursor of acetylcholine, a neurotransmitter involved in memory, attention, and skeletal muscle contraction. Glycerol-1-phosphate is used to support cellular membranes.[1]
Alpha-GPC appears to easily cross the blood-brain barrier and is rapidly absorbed. It is currently the best cholinergic for increasing plasma and brain choline levels.[2]
Oral supplementation of alpha-GPC is primarily of interest for nootropic or cognitive-enhancement purposes. There are a number of rodent studies that support this effect, but it has yet to be shown in otherwise healthy humans. In older adults with mild to moderate dementia — which involves disrupted cholinergic neurotransmission — alpha-GPC improves cognitive symptoms (e.g., memory and attention impairment).[3][1] Alpha-GPC may also improve the effectiveness of acetylcholinesterase inhibitors (i.e., drugs that increase acetylcholine availability by slowing down its breakdown), which are used for treating Alzheimer’s disease.[3]
Athletes are another population that may benefit from alpha-GPC supplementation. Preliminary evidence suggests that alpha-GPC increases vertical jump power.[4][5] Additionally, a pilot study reported that alpha-GPC increased peak bench press force, but not peak power or rate of force development.[6] Whether alpha-GPC increases isometric strength is currently unclear.[5][7]
Mechanistic evidence suggests that alpha-GPC exerts its effects by increasing the synthesis and release of acetylcholine in the brain, where it is involved in memory, motivation, arousal, and attention.[12][13][14][15]
Acetylcholine is also responsible for the action potential that stimulates muscles to contract. Therefore, it’s theorized that increased acetylcholine levels lead to a stronger signal for muscle contraction and, consequently, increased force production.

Must have
If you're making your own nootropic stacks, this is a 100% must have. If I do not take alpha GPC when I take nootropics or stronger stims, I get headaches due to choline depletion. This keeps the tank full and focus/mental energy lasting longer.
