Ginkgo Biloba in Zeaxan
Zeaxan lists ginkgo biloba powder 8th of 11 ingredients, spelled "Gingko" on the label, and prints no amount.

It has no eye trials in our sources, so ask your doctor first if you take a blood thinner.

The basics
What is ginkgo biloba, and why is it in Zeaxan?
Ginkgo biloba is an herb from the ginkgo tree, usually sold for circulation and memory. Zeaxan includes it as a powder, 8th of the 11 ingredients in its blend.
The label does not say which part of the plant is used or why ginkgo is in an eye formula. It also spells the name "Gingko". That is a label spelling, not a different plant. Here is what the label tells you, next to the research.
| Label name | Gingko Biloba Powder |
|---|---|
| What it is | Ginkgo biloba powder (plant part not stated) |
| Form | Herbal powder |
| Place in the blend | 8 of 11 (heaviest first) |
| Amount per 2 capsules | Not published (listed 8th) |
| Amount used in research | No eye trials in our sources; not shown to prevent dementia |
| Strength of evidence | Not shown for eyes |
| Why it is in the formula | An herb sold for circulation and memory |
| Main caution | May raise bleeding risk with warfarin and other blood thinners; dizziness, stomach upset, headache. |
The main caution
Can you take ginkgo with warfarin or other blood thinners?
Only after your doctor says yes. NCCIH says ginkgo may increase the risk of bleeding in people who take anticoagulants such as warfarin (NCCIH, ginkgo).
The amount in Zeaxan is not published, so your doctor cannot weigh a known dose. That makes the label's own advice more important: anyone with a known medical condition should consult a physician before using it.
Show your doctor or pharmacist the full ingredient list, not just the word "eye". Ginkgo is easy to miss when it sits 8th in a long blend. Tell them about every other supplement you take as well (NCCIH, 2019).

Side effects
What are the side effects of ginkgo?
The most common are dizziness, stomach upset and headache (NCCIH, ginkgo). Keep notes during your first weeks so you can tell your doctor what changed.
| What you might notice | What to do |
|---|---|
| Dizziness | Stop taking it and tell your doctor, especially if you are older or fall easily. |
| Stomach upset | Note when it happens. The label says to take Zeaxan between meals; ask a pharmacist if that does not suit you. |
| Headache | Write it down. If it keeps coming back, stop and ask your doctor. |
| Unusual bruising or bleeding | Stop and call your doctor, above all if you take a blood thinner (NCCIH, ginkgo). |
Side effects of the whole formula are covered on the side effects page.
The research
Does ginkgo help your eyes or your memory?
Neither use is shown in our sources. We found no eye trials of ginkgo, and NCCIH says it has not been shown to prevent or slow dementia (NCCIH, ginkgo).
That leaves ginkgo in Zeaxan with a clear caution and no clear eye benefit. The FTC says a health claim needs solid human trials behind it (FTC, 2022). Zeaxan itself has never been tested in one.
- Listed 8th, so by our arithmetic it weighs at most 75 mg of the 600 mg blend.
- Plant part and extract strength are not stated.
- No lab report is published for this batch or any other.

FAQ
Ginkgo questions
Does Zeaxan contain ginkgo biloba?
Yes. Ginkgo biloba powder is the 8th of 11 ingredients in the Zeaxan blend, printed on the label as "Gingko Biloba Powder". The amount is not published, and the label does not say which part of the plant is used. By our arithmetic it weighs at most 75 mg.
Can ginkgo make you bleed more easily?
It may, especially if you take a blood thinner. NCCIH says ginkgo may increase bleeding risk in people taking anticoagulants such as warfarin (NCCIH, ginkgo). If you notice unusual bruising or bleeding while taking Zeaxan, stop and call your doctor. Tell any doctor treating you that you take it.
What side effects does ginkgo have?
The common ones are dizziness, stomach upset and headache (NCCIH, ginkgo). The bigger concern is bleeding risk for people on blood thinners. Because Zeaxan does not publish its ginkgo amount, it is hard to predict how strongly any one person will react.
Does ginkgo improve eyesight?
There is no good evidence for that. Our sources include no eye trials of ginkgo, and NCCIH says it has not been shown to prevent or slow dementia either (NCCIH, ginkgo). If your eyesight is changing, an eye exam is the right next step, not an herb.
Who should avoid the ginkgo in Zeaxan?
Anyone on warfarin or another blood thinner should ask a doctor before taking it (NCCIH, ginkgo). The label also says pregnant or nursing mothers, people under 18 and anyone with a known medical condition should consult a physician first, and it is for adult use only.
Is "Gingko" on the Zeaxan label a different herb?
No. "Gingko" is how the label spells ginkgo biloba, the same herb. It is a spelling quirk, not a different plant or a special form. The cautions for ginkgo, including the bleeding risk with blood thinners, apply in full. Use the usual name, ginkgo, when you tell your doctor.
Does ginkgo help memory?
It has not been shown to prevent or slow dementia, according to NCCIH (NCCIH, ginkgo). Ginkgo is often sold for memory, but the label on Zeaxan makes no memory claim. If memory changes worry you, talk to your doctor rather than relying on a supplement.
