The bottom line No known interaction

We found no known interaction between Phaseolus Vulgaris and Amphetamine in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.

Phaseolus Vulgaris and Amphetamine

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 Amphetamine and Phaseolus Vulgaris 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.

Phaseolus Vulgaris safety at a glance

Phaseolus Vulgaris overall Use caution Beans are a safe food when cooked, but concentrated extracts have less safety data and may cause digestive upset.
Pregnancy Use caution Beans as food are fine, but concentrated extracts are not well studied in pregnancy, so avoid them unless your doctor approves.
Breastfeeding Use caution Beans as food are fine, but there is little data on concentrated extracts during breastfeeding, so use caution.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Amphetamine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Amphetamine is filed under 6 classifications — including monoamine oxidase inhibitors (maois), amphetamines, stimulant drugs. Phaseolus Vulgaris has documented interactions with 1 drug class — the most serious being antidiabetes drugs (moderate) — and none of Amphetamine’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What Phaseolus Vulgaris Itself Has Been Linked To

This is not an interaction — nothing below involves Amphetamine. It is the side-effect record for Phaseolus Vulgaris on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Phaseolus Vulgaris, this list is the first place to look. 2 entries are worth acting on rather than waiting out — marked below.

    “Topically, Phaseolus vulgaris may cause contact dermatitis in sensitive individuals. A case of occupational contact dermatitis characterized by pruritus, erythema, eczema, and dyspnea has been reported for a 41-year-old farmer who handled the green parts of Phaseolus vulgaris.”

Overlapping uses

What Amphetamine Is Prescribed For, and What Phaseolus Vulgaris Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Amphetamine is a prescription medicine with approved uses on its FDA label. Phaseolus Vulgaris is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Amphetamine is prescribed for: Amphetamine treats Attention Deficit Hyperactivity Disorder (ADHD) in patients 6 years and older. Adzenys XR-ODT, Dyanavel XR, and the amphetamine extended-release orally disintegrating tablet formulations are specifically approved for ADHD in this age group. Amphetamine Sulfate tablets and Evekeo (amphetamine sulfate tablets) are also approved for narcolepsy (a sleep disorder causing uncontrollable daytime sleepiness) and as a short-term aid in a calorie-restricted weight-loss program for exogenous obesity (weight gain from external factors like overeating) in patients who have not responded to other approaches.

Phaseolus Vulgaris has been studied for:

  • Obesity Natural Medicines rates the evidence for Phaseolus Vulgaris: Possibly Effective Read what the research shows

    Phaseolus Vulgaris for obesity

    Oral Phaseolus vulgaris extract may reduce body weight and waist circumference in overweight and obese adults.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Amphetamine on your own; if you are taking Phaseolus Vulgaris for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Phaseolus Vulgaris

What is Phaseolus Vulgaris?

  • Weight management
  • Carbohydrate ('starch') blocking
  • Blood sugar support
  • General nutrition and fiber

Phaseolus vulgaris, the common bean, is widely eaten as food, and a concentrated white bean extract is marketed as a 'carb blocker' for weight loss. Some small studies suggest it may modestly reduce starch digestion, but the evidence for meaningful weight loss is limited and mixed. Talk to your pharmacist or doctor before using it as a supplement, and remember beans must be cooked thoroughly because raw or undercooked beans can be toxic.

Phaseolus vulgaris · Fabaceae · Seeds (beans), bean pods, and extracts of the seed · Capsules, tablets, powder, standardized white bean extract ('Phase 2'), whole beans as food

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

Phaseolus Vulgaris: dosing

There is no official standardized dose of Phaseolus vulgaris extract for weight loss or any other use. Products vary widely in strength and in how they are standardized (for example, by amount of alpha-amylase inhibitor activity).The safest approach is to follow the directions on the product label and not exceed them. Extract is usually taken shortly before starchy meals. Beans as food can simply be enjoyed as part of a balanced diet.

Are Phaseolus Vulgaris and Amphetamine used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together.

How was the Phaseolus Vulgaris and Amphetamine combination checked?
Interactions in our licensed database are recorded against drug classes. Amphetamine is filed under 6 classifications, and Phaseolus Vulgaris has documented interactions with 1 drug class — none of Amphetamine's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Phaseolus Vulgaris interact with any other medications?
Yes. Phaseolus Vulgaris has 86 documented drug interactions in our database — Amphetamine is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Amphetamine interact with any supplements?
Yes. Amphetamine has documented interactions with 130 supplements in our database — Phaseolus Vulgaris is not one of them. The Amphetamine interaction page linked on this page lists every one, ranked by severity.
