Supplements to avoid with Wellbutrin (bupropion) start with St. John’s Wort and stimulant-heavy products like concentrated caffeine, bitter orange, and yohimbe. Wellbutrin lowers the seizure threshold and works on mood-related brain chemistry, so the wrong supplement can add risk instead of benefit.
The best-documented supplement interactions with Wellbutrin involve St. John’s Wort — an herb that acts on the same mood-related neurotransmitters and changes how the body processes many medications — and stimulant supplements such as concentrated caffeine pills, bitter orange (synephrine), and yohimbe, which stack on top of Wellbutrin’s activating effects. Routine multivitamins have no well-documented interaction with bupropion, but you should still show your prescriber everything you take.
This page is for informational purposes only and is not medical advice. The interactions listed here are well-documented but not exhaustive — no list can cover every product or personal situation. Always consult your doctor or pharmacist before combining any supplement with prescription medication, and never start or stop a medication or supplement based on what you read online.
Wellbutrin (bupropion) is an antidepressant that increases norepinephrine and dopamine activity in the brain. It is also known to lower the seizure threshold in a dose-dependent way — which is exactly why its official patient information warns against combining it with anything else that pushes in the same direction.
That creates two supplement problem areas. First, herbal products that act on mood-related brain chemistry, where St. John’s Wort is the standout: MedlinePlus specifically instructs patients taking bupropion to tell their doctor if they take St. John’s Wort. Second, stimulants: products that add jitteriness, raise heart rate and blood pressure, or further stress the nervous system on top of an already activating medication.
These are the supplements standard references flag for people taking bupropion. It is not an exhaustive list — when in doubt, ask your pharmacist.
| Supplement | Risk | What to do |
|---|---|---|
| St. John’s Wort | Acts on the same mood-related neurotransmitter systems as antidepressants and induces drug-metabolizing enzymes, making combined effects unpredictable. NIH advises caution combining it with any antidepressant. | Avoid the combination. If you already take it, tell your prescriber before stopping — do not just quit both. |
| Concentrated caffeine (pills, high-dose energy supplements) | Additive stimulation: jitteriness, insomnia, raised heart rate and blood pressure on top of an already activating drug. | Keep caffeine moderate and consistent. Skip caffeine pills and “extreme energy” formulas. |
| Bitter orange (synephrine) | A stimulant common in weight-loss and pre-workout blends; can raise heart rate and blood pressure. | Avoid stimulant weight-loss and pre-workout blends while on bupropion. |
| Yohimbe (yohimbine) | A stimulant herb linked to anxiety, elevated blood pressure, and rapid heart rate — effects that compound Wellbutrin’s activating profile. | Avoid. If a formula lists yohimbe, choose something else. |
Standard daily supplements — a basic multivitamin, vitamin D, magnesium, fish oil at typical doses — have no well-documented interaction with bupropion. The practical risk with Wellbutrin comes from herbal mood products and stimulants, not from ordinary vitamins and minerals.
The caveat: multi-ingredient formulas. A “focus” or “energy” blend can contain synephrine or heavy caffeine without making it obvious on the front of the bottle. Read the full ingredient panel, and list everything for your prescriber.
A list like this covers the best-documented supplement interactions with Wellbutrin, but it cannot cover every product on the shelf. Multi-ingredient formulas — greens powders, sleep blends, pre-workouts, “hormone support” capsules — often bury a risky ingredient halfway down the label where nobody looks.
Suppi solves this the practical way: scan the label, and the app cross-checks every ingredient against your medications and the rest of your supplement stack using a database built on 500+ peer-reviewed clinical studies. You can also start with our free supplement interaction checker overview to see how it works, then bring your full list to your doctor or pharmacist for the final word.
