Lion's mane (Hericium erinaceus)

Lion's mane (Hericium erinaceus) is an edible mushroom studied for compounds that may influence nerve growth factors.

Choline (choline bitartrate, alpha-GPC)

Choline is an essential nutrient used to make cell membranes and the neurotransmitter acetylcholine. EFSA set an adequate intake of 400 mg a day for adults². Supplements supply it as choline bitartrate, alpha-GPC or citicoline.

L-tyrosine

L-tyrosine is an amino acid that the body uses to make the neurotransmitters dopamine and noradrenaline. It is found in protein-rich foods; N-acetyl-L-tyrosine is a related form³.

Phosphatidylserine, lecithin and phospholipids

Phosphatidylserine and other phospholipids are components of cell membranes. Lecithin is a mixture of phospholipids, often from sunflower or soy.

Vitamin B6 (pyridoxine, P-5-P)

Vitamin B6 is involved in protein metabolism and in making neurotransmitters. EFSA set population reference intakes of 1.7 mg a day for men and 1.6 mg a day for women⁴.

Mucuna pruriens (velvet bean, L-DOPA)

Mucuna pruriens seeds naturally contain L-DOPA (levodopa), the precursor of dopamine and the main medicine for Parkinson's disease.

Methylene blue

Methylene blue (methylthioninium chloride) is a licensed medicine for methaemoglobinaemia and a dye. It is marketed as a "nootropic".

Huperzine A

Huperzine A is an alkaloid from the club moss Huperzia serrata. It inhibits acetylcholinesterase, the enzyme that breaks down the neurotransmitter acetylcholine, and it has been used as a medicine for dementia in China⁵.

Lion's mane (Hericium erinaceus)

A small pilot study in healthy adults found lion's mane safe and well tolerated, with small-to-moderate effects on cognitive function that warrant larger trials⁶.

Choline (choline bitartrate, alpha-GPC)

The EU authorises claims that choline contributes to normal lipid metabolism, homocysteine metabolism and liver function for foods that are a source of choline⁷. Claims that choline improves focus or exercise performance are not authorised.

L-tyrosine

A review found that tyrosine may support cognitive performance in short-term stressful or cognitively demanding situations, when these neurotransmitters are temporarily depleted, but found no consistent effect on physical exercise performance³.

Phosphatidylserine, lecithin and phospholipids

A 2026 systematic review concluded that current evidence does not support citicoline or phosphatidylserine compounds as effective cognitive enhancers in mental disorders⁸.

Vitamin B6 (pyridoxine, P-5-P)

Authorised EU claims include that vitamin B6 contributes to normal protein and glycogen metabolism, normal functioning of the nervous system and the reduction of tiredness and fatigue⁷.

Mucuna pruriens (velvet bean, L-DOPA)

A 12-month randomised trial in untreated Parkinson's disease in sub-Saharan Africa found Mucuna pruriens could be a cost-effective alternative where commercial levodopa is not available⁹. There is no good evidence that it raises testosterone or improves mood or performance in healthy people.

Methylene blue

There are no robust trials showing cognitive benefits in healthy people.

Huperzine A

A Cochrane review found some benefit on cognitive function in people with Alzheimer's disease, but only one study was of adequate quality and size, so there was inadequate evidence to recommend its use⁵. A Cochrane review in mild cognitive impairment found the evidence insufficient¹⁰.

There is no good evidence that huperzine A improves focus or performance in healthy people.

Lion's mane (Hericium erinaceus)

The human evidence is from small pilot studies⁶.

Choline (choline bitartrate, alpha-GPC)

Evidence on cognitive or performance effects in healthy adults is limited.

L-tyrosine

Most studies are small and use single doses in laboratory settings³.

Phosphatidylserine, lecithin and phospholipids

Studies have methodological limitations and a high risk of bias⁸.

Vitamin B6 (pyridoxine, P-5-P)

Benefits of intakes well above the reference intake have not been shown in people who are not deficient.

Mucuna pruriens (velvet bean, L-DOPA)

The trial used standardised preparations under medical supervision; larger double-blind trials are needed⁹. Supplements rarely state their L-DOPA content.

Methylene blue

Clinical evidence concerns specific medical uses.

Huperzine A

The trials are mostly small, of limited quality and in people with cognitive disease, so they do not apply to healthy users⁵¹⁰.

• Do not use during pregnancy or breastfeeding, or if you have G6PD deficiency.
• Keep out of reach of children.

Lion's mane (Hericium erinaceus)

Generally well tolerated; people with mushroom allergy should avoid it⁶.

Choline (choline bitartrate, alpha-GPC)

High intakes can cause a fishy body odour, sweating and digestive upset.

L-tyrosine

People taking MAO inhibitors or thyroid medication should not use tyrosine supplements without medical advice.

Phosphatidylserine, lecithin and phospholipids

Generally well tolerated; soy lecithin may not be suitable for people with soy allergy.

Vitamin B6 (pyridoxine, P-5-P)

Excess vitamin B6 can cause peripheral neuropathy (nerve damage with tingling or numbness). EFSA set a tolerable upper intake level of 12 mg a day for adults, including pregnant and lactating women¹. Count vitamin B6 from all supplements taken.

Mucuna pruriens (velvet bean, L-DOPA)

L-DOPA can cause nausea, low blood pressure, involuntary movements and psychiatric effects, and it interacts with MAO inhibitors, antipsychotics and Parkinson's medicines. People with heart disease, psychiatric conditions or melanoma history should not use it without medical advice.

Methylene blue

Methylene blue inhibits monoamine oxidase and can cause serotonin syndrome when combined with antidepressants¹¹. It is dangerous for people with G6PD deficiency and turns urine blue-green.

Huperzine A

As an acetylcholinesterase inhibitor, huperzine A can cause nausea, diarrhoea, sweating and a slow heart rate, and it may interact with medicines that affect acetylcholine or heart rate. Anyone taking medication or with heart, lung or digestive conditions should ask a doctor first.

Flagged for compliance review: this product is listed as a food supplement in our catalogue, but its EU status (food supplement, novel food or medicinal product) has not been verified. No benefits or health claims are made.

Choline (choline bitartrate, alpha-GPC)

Choline is a permitted nutrient source in EU food supplements¹²⁷.

L-tyrosine

Amino acids such as L-tyrosine are used in EU food supplements under national rules. No health claim is authorised⁷.
