The Bottom Line

Yes, you can safely take vitamin B9 (folate/folic acid/methylfolate) and ginkgo biloba together. There is no known interaction between them, so you do not need to change your routine.

VERDICT

Vitamin B9 and Ginkgo Biloba together are safe for most adults. These two supplements work through independent pathways, so neither reduces the other's effectiveness or increases side effects. You can combine them without special timing, spacing, or dietary adjustments.

Safe to combine Moderate evidence
01 / MECHANISM

How They Interact

Folate is a water-soluble B vitamin absorbed primarily in the upper small intestine via the reduced folate carrier and proton-coupled folate transporter. Ginkgo biloba's active compounds—flavonoid glycosides and terpene lactones—are absorbed independently and metabolized by hepatic cytochrome P450 enzymes. These distinct absorption and metabolic pathways do not overlap, so there is no competition for uptake, transport, or shared receptors. Ginkgo also does not influence folate-dependent enzymes such as methylenetetrahydrofolate reductase (MTHFR), and its mild antiplatelet effect involves platelet-activating factor antagonism, which is unrelated to one-carbon metabolism. Therefore, the biological basis for a clinically significant interaction is absent.

02 / BEST PRACTICES

How To Take Them

Because there is no interaction, you can take vitamin B9 and ginkgo biloba together or at separate times based on your preference. For most people, taking both in the morning with breakfast is convenient and helps build a consistent habit. If you take other medications that require an empty stomach, take ginkgo with food to reduce stomach upset. If you miss a dose, simply resume at your next scheduled time and never exceed the recommended daily amount on the label. If you are using methylfolate, you can also take it with ginkgo without worrying about competition; just keep your supplement routine regular and track how you feel.

03 / FORM MATTERS

Form & Quality Differences

The form of vitamin B9—folic acid, natural food folate, or L-methylfolate—does not affect how it interacts with ginkgo biloba. Regardless of which form you use, the interaction status remains safe. If you have an MTHFR polymorphism, you may prefer L-methylfolate for better absorption, but that is a personal choice completely unrelated to ginkgo.

04 / COMMON STACKS

Where This Pair Shows Up

This pair is not typically sold as a dedicated combination, but both appear together in cognitive-support and homocysteine-management formulations alongside vitamin B12, vitamin D, and omega-3 fatty acids.

Frequently Asked Questions

Who Should Be Careful If you are pregnant, planning to become pregnant, or breastfeeding, avoid ginkgo biloba due to a lack of safety data, even though folate supplementation remains important and safe. If you take blood-thinning medications such as warfarin, clopidogrel, or daily aspirin, talk to your healthcare provider before adding ginkgo because of its mild antiplatelet activity. People with bleeding disorders or a history of hemorrhagic stroke should also exercise caution with ginkgo. These cautions are unrelated to folate, which is safe at recommended doses in combination with most supplements and medications.
