Amino acidsWeak evidence

L-serine

Also known as: serine

Serine is a non-essential amino acid needed to make membrane phospholipids, glycine and D-serine in the brain. The body normally makes it itself.

What it is used for

  • Nervous system support in rare inherited disorders and research settings – weak evidence
  • Better sleep – weak evidence from small studies

Forms and how they differ

L-serine

standard form in capsules and powder

phosphatidylserine

a different substance (phospholipid), do not confuse with serine

When to take it

With food; for sleep in the evening.

Pairs well with

Glycine, magnesium.

Do not combine / separate

Do not confuse with phosphatidylserine – it is a different supplement.

Watch out for

Long-term safety of higher doses is not well studied. Consult your doctor or pharmacist if you are pregnant, breastfeeding, have kidney or liver disease or take any medicines.

Safety

Do not exceed the label dose.

Practical tip

For memory support, phosphatidylserine is better researched than L-serine.
