Bear's Garlic and Carbidopa, Levodopa

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Carbidopa, Levodopa and Bear's Garlic in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

From our pharmacist’s overview on the Carbidopa, Levodopa page

“Carbidopa/levodopa (Sinemet, Rytary) anchors Parkinson's treatment, and because symptom control hinges on how much levodopa actually reaches the brain, the 43 supplements and herbs on this list deserve real respect before you add any of them. Eight carry a major rating, and almost all of the serious entries weaken the drug rather than…”

About Bear's Garlic

What is Bear's Garlic?

Bear's Garlic
  • Seasoning and culinary flavoring
  • Heart and blood vessel health
  • Blood pressure support
  • Digestive complaints
  • General 'cleansing' or detox traditions

Bear's garlic is a wild relative of garlic enjoyed mainly as a mild-tasting food. Some early laboratory studies hint at heart and blood vessel benefits, but solid human evidence is lacking, so it should be viewed as a flavorful food rather than a proven remedy. As food it is generally well tolerated, but supplements or large amounts have not been well studied for safety.

Allium ursinum · Amaryllidaceae · Leaves and bulb · Fresh leaves, dried herb, tinctures, capsules, juice, teas, culinary pesto

An interaction check asks whether these two react with each other — it does not ask whether Bear's Garlic is a good idea for someone in your situation. Here is what our Bear's Garlic record says about it on its own.

Bear's Garlic: dosing

There is no established standardized dose for bear's garlic. As a food, people use the fresh leaves in cooking to taste during its spring season.For supplement forms such as capsules or tinctures, there is no proven medicinal dose.
