7.California Poppy
It’s related to the opium poppy but is a different flower species. California poppy has been used in traditional medicine as a sedative. Scientists have found that it helps raise the levels of GABA, the relaxation-boosting chemical. But there’s little research on whether California poppy extracts work. It’s likely safe to use for short periods. Possible side effects include stomach problems.
8.Glycine
This tiny amino acid can have a big impact on your sleep. It may raise the amount of serotonin, a brain chemical that affects slumber. It also helps your blood flow and drops your body temperature, both of which encourage you to nod off. Glycine supplements are viewed as safe. Try taking 3 grams about an hour before bedtime.
