Key vitamins, phospholipids and amino acids to optimise the function of the brain neurotransmitter, acetylcholine, for healthy concentration, memory and learning. Choline is a precursor of acetylcholine and a vital component of nerve cells. Phosphatidyl serine also plays a role in brain synapses. Both support the storage and retrieval of information in the brain (both decline with age). Arginine pyroglutamate supports acetylcholine receptors and improves communication between the left and right brain hemispheres. Acetyl-L-carnitine provides the "acetyl" component to make acetylcholine. Carnitine can be used directly by the brain as fuel. Two capsules provide: 260mg Choline (bitartrate), 200mg Arginine pyroglutamate, 200mg Pantothenic acid (Vitamin B5) (calcium d-pantothenate), 100mg Acetyl-L-carnitine, 30mg Phosphatidyl serine, 20mg vitamin B3 (as nicotinamide),150g Folic acid, 20g vitamin B12 (methylcobalamin). Encapsulated with these natural ingredients: Hydroxypropyl methylcellulose, silicon dioxide, vegetable magnesium stearate, microcrystalline cellulose. Suggested intake: Take 2 capsules once or twice a day (children over 8 years, 1 a day), with meals.
