The bottom line No known interaction

We found no known interaction between Beta-methylphenethylamine (bmpea) and Lanthanum Carbonate 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. Additionally, although there is no interaction, the label for Lanthanum Carbonate states a food rule worth keeping to.

Beta-methylphenethylamine (bmpea) and Lanthanum Carbonate

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 Lanthanum Carbonate and Beta-methylphenethylamine (bmpea) 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.

How we checked

Why No Interaction Is Listed for Lanthanum Carbonate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Lanthanum Carbonate is filed under a single classification — oral drugs. Beta-methylphenethylamine (bmpea) has documented interactions with 3 drug classes — the most serious being cytochrome p450 2d6 (cyp2d6) substrates (moderate), cytochrome p450 3a4 (cyp3a4) substrates (moderate) and stimulant drugs (moderate) — and none of Lanthanum Carbonate’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 to actually watch for

What Beta-methylphenethylamine (bmpea) Itself Has Been Linked To

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

  • A stroke or mini-stroke Worth acting on Additional detail

    “Hemorrhagic stroke was reported in a healthy 53-year-old female who took a specific supplement (Jacked Power, MM sports) 30 minutes prior to exercise. It was not labeled as containing BMPEA, but testing showed a level of 290 mg per dose.”

We read the ADVERSE REACTIONS section of Lanthanum Carbonate’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Lanthanum Carbonate column appears here.

How to take them

Some Lanthanum Carbonate Products Have a Food Rule — Beta-methylphenethylamine (bmpea) Should Not Break It

At least one FDA label for a product containing Lanthanum Carbonate says to take it with food. If you take Beta-methylphenethylamine (bmpea) on an empty stomach out of habit, keep them separate — and take Lanthanum Carbonate with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Lanthanum Carbonate products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

Do not store FOSRENOL Oral Powder for future use once mixed with food.

From the Dosage and Administration section of the FDA label we read for Lanthanum Carbonate — where that label names a specific product, the instruction is that product's. See the Lanthanum Carbonate drug page ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

About Beta-methylphenethylamine (bmpea)

What is Beta-methylphenethylamine (bmpea)?

  • Weight loss
  • Pre-workout energy
  • Athletic performance
  • Appetite suppression
  • Mental focus

Beta-methylphenethylamine (BMPEA) is a synthetic stimulant chemically similar to amphetamine that has been found in some weight-loss and sports supplements, often without being clearly listed on the label. It is not an approved or well-studied dietary ingredient, and regulators have warned that it may carry real cardiovascular risks. Because of safety concerns and the lack of human research, it is best avoided.

Synthetic chemical; also reported as a constituent of some Acacia species · Capsules, tablets, and powders sold as pre-workout, weight-loss, or 'energy' supplements

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

Beta-methylphenethylamine (bmpea): dosing

There is no established or recommended dose for BMPEA, and no safe dose has been determined through research. It is not an approved ingredient, so any amount in a supplement is unregulated and may not match what the label says.We do not recommend taking BMPEA.

About Lanthanum

What Is Lanthanum Used For?

Brand name: Fosrenol

Lanthanum carbonate — available as lanthanum carbonate chewable tablets and as Fosrenol in both chewable tablet and oral powder forms — is used to lower elevated serum phosphate (too much phosphate in the blood) in people with end-stage renal disease (ESRD), the most advanced stage of chronic kidney disease.

Managing high phosphate in ESRD typically involves eating less phosphate-rich food, removing phosphate through dialysis, and using a phosphate binder like lanthanum carbonate to reduce how much phosphate is absorbed from meals.

Most-Reported Side Effects for Lanthanum Carbonate

From FAERS, the FDA’s public side-effect reporting system (0 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Nausea 493 reports
Vomiting 480 reports
Constipation 376 reports
Sepsis 368 reports
Abdominal pain 365 reports

Taking Beta-methylphenethylamine (bmpea) and Lanthanum Carbonate Together: Common Questions

Is it safe to take Beta-methylphenethylamine (bmpea) with Lanthanum Carbonate?
We do not list a known interaction between Beta-methylphenethylamine (bmpea) and Lanthanum Carbonate. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Should I take Beta-methylphenethylamine (bmpea) and Lanthanum Carbonate at the same time of day?
At least one FDA label for a product containing Lanthanum Carbonate says to take it with food. If you take Beta-methylphenethylamine (bmpea) on an empty stomach out of habit, keep them separate and take Lanthanum Carbonate with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Lanthanum Carbonate products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the Beta-methylphenethylamine (bmpea) and Lanthanum Carbonate combination checked?
Interactions in our licensed database are recorded against drug classes. Lanthanum Carbonate is filed under 1 classification, and Beta-methylphenethylamine (bmpea) has documented interactions with 3 drug classes — none of Lanthanum Carbonate'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 Beta-methylphenethylamine (bmpea) interact with any other medications?
Yes. Beta-methylphenethylamine (bmpea) has 813 documented drug interactions in our database — Lanthanum Carbonate 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 Lanthanum Carbonate interact with any supplements?
Yes. Lanthanum Carbonate has documented interactions with 17 supplements in our database — Beta-methylphenethylamine (bmpea) is not one of them. The Lanthanum Carbonate interaction page linked on this page lists every one, ranked by severity.
