Folate (B9) and L-Tryptophan
Folate supports the methylation cycle needed to recycle and activate neurotransmitter cofactors.
Folate (B9)
The active B vitamin behind methylation, mood, and pregnancy health.
L-Tryptophan
The dietary precursor to serotonin and melatonin.
Great to combine
These two are frequently stacked together; they complement each other and are commonly taken at the same time.
How to take them
Folate (B9)
- Dose
- 400–1,000 mcg DFE per day; up to 1,000 mcg L-Methylfolate for MTHFR
- Timing
- With or without food; morning is common to support daytime methylation
L-Tryptophan
- Dose
- 500–2,000 mg per day
- Timing
- Evening on an empty stomach, or with a small carbohydrate snack to improve brain uptake

Frequently asked
Can you take Folate (B9) and L-Tryptophan together?
Yes, they are commonly taken together. Folate supports the methylation cycle needed to recycle and activate neurotransmitter cofactors.
What's the best time to take Folate (B9) and L-Tryptophan?
Around the same time works well. Folate (B9): With or without food; morning is common to support daytime methylation. L-Tryptophan: Evening on an empty stomach, or with a small carbohydrate snack to improve brain uptake.
How do Folate (B9) and L-Tryptophan interact?
Synergy: Work better together than alone. Folate supports the methylation cycle needed to recycle and activate neurotransmitter cofactors.
Related pairings
Folate (B9) + TMG (Trimethylglycine)
TMG provides a folate-independent route to remethylate homocysteine (via BHMT), complementing the folate/B12 pathway, useful when folate cycling is impaired.
Folate (B9) + Vitamin B12 (Cobalamin)
Folate and B12 work as a pair in the methylation cycle. B12 is required for folate to re-enter active circulation; deficiency in either disrupts both.
Folate (B9) + Vitamin B6 (Pyridoxine)
B6 and folate work together to lower homocysteine and support methylation balance.
Folate (B9) + Iron
Both folate and iron are needed for healthy red blood cell production. Deficiency in either causes anaemia.
