Short answer

We found no documented interaction between Elderberry and Glutamine in the sources below. That isn't proof the combination is right for you: check each one's cautions, and ask your pharmacist if you take medication.

Elderberry

What it is: The dark purple berry of the black elder tree, traditionally used for colds and flu.

What the research says: Preliminary research suggests it may ease cold or flu symptoms. There's no good evidence for other uses.

Cautions

  • Raw or unripe berries, leaves and stems are toxic; supplements use processed fruit.
  • Little is known about use in pregnancy or breastfeeding.

Medicines to check

  • Talk to your clinician if you take any medicine

Glutamine

What it is: An amino acid the body makes and uses for energy and to build protein.

What the research says: It has little or no benefit for strength or recovery. It's studied mainly in cancer care and after surgery.

Cautions

  • Studies report no side effects at up to 45 g a day for several weeks; reported side effects elsewhere include headache and nausea.
  • Don't confuse it with glutamate, which is a different substance.
