Drug & supplement interaction

Branched-chain Amino Acids (bcaa) + Nintedanib Esylate

Nintedanib Esylate brand name: Ofev.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Oct 4, 2026
The bottom line No known interaction

We found no known interaction between Branched-chain Amino Acids (bcaa) and Nintedanib Esylate 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 Nintedanib Esylate states a food rule worth keeping to, and the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Interaction report

Branched-chain Amino Acids (bcaa) and Nintedanib Esylate

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 Nintedanib Esylate and Branched-chain Amino Acids (bcaa) 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 Nintedanib Esylate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Nintedanib Esylate is filed under 5 classifications — including anticoagulant/antiplatelet drugs, p-glycoprotein substrates, cytochrome p450 3a4 (cyp3a4) substrates. Branched-chain Amino Acids (bcaa) has documented interactions with 2 drug classes — the most serious being levodopa (major) and antidiabetes drugs (moderate) — and none of Nintedanib Esylate’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

No Interaction Found — But Data Suggests Branched-chain Amino Acids (bcaa) and Nintedanib Esylate May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. One of them is worth acting on rather than waiting out — marked below.

    “Orally and intravenously, BCAAs can cause fatigue and loss of motor coordination due to increased plasma ammonia levels. Short-term use of 60 grams of BCAAs containing leucine, isoleucine, and valine for 7 days in patients with normal metabolic function seems to increase levels of ammonia, but not to toxic plasma levels. However, liver function should be monitored with high doses or long-term use.”

Reported for Branched-chain Amino Acids (bcaa) but not commonly for Nintedanib Esylate: bloating or gas.

Effects for Nintedanib Esylate come from the ADVERSE REACTIONS section of its FDA label; effects for Branched-chain Amino Acids (bcaa) come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 31,339 voluntary FDA FAERS reports for Nintedanib Esylate that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

How to take them

Some Nintedanib Esylate Products Have a Food Rule — Branched-chain Amino Acids (bcaa) Should Not Break It

At least one FDA label for a product containing Nintedanib Esylate says to take it with food. If you take Branched-chain Amino Acids (bcaa) on an empty stomach out of habit, keep them separate — and take Nintedanib Esylate 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 Nintedanib Esylate 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.

2 DOSAGE AND ADMINISTRATION Recommended dosage: 150 mg taken orally twice daily approximately 12 hours apart taken with food.

From the Dosage and Administration section of the FDA label we read for Nintedanib Esylate — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

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.

See Every Supplement That Interacts With Nintedanib Esylate

This page covers Branched-chain Amino Acids (bcaa) only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Nintedanib Esylate page lists 285 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Danshen (major), Grapefruit (major), Piracetam (major) and St. John's Wort (major).

By severity: 5 major · 240 moderate · 40 minor.

From our pharmacist’s overview on the Nintedanib Esylate page

“You take Ofev (nintedanib) to slow lung scarring, and this page deserves a careful read before any supplement joins it. Of the 285 ingredients here, the biggest cluster, over 200, can add to bleeding risk, a real concern since nintedanib itself can make you bleed more easily.”

About Branched-chain Amino Acids (bcaa)

What is Branched-chain Amino Acids (bcaa)?

  • Muscle building and exercise recovery
  • Reducing exercise fatigue
  • Preserving muscle during weight loss
  • Liver disease support
  • Tardive dyskinesia (under study)

Branched-chain amino acids (leucine, isoleucine, and valine) are essential nutrients commonly taken by athletes for muscle support and recovery. Evidence shows modest benefits for some uses, but a balanced protein source usually provides the same amino acids. They are generally well tolerated for most healthy adults, but check with your pharmacist or doctor before use, especially if you have a medical condition.

Powder, capsules, tablets, ready-to-drink beverages

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

Branched-chain Amino Acids (bcaa): dosing

There is no single official dose for BCAA supplements, and the amount used in studies has varied widely. Products differ in how much leucine, isoleucine, and valine they contain, and in the ratio between them.The best approach is to follow the directions on the product label and not take more than recommended.

About Nintedanib

What Is Nintedanib Used For?

Brand name: Ofev

Nintedanib treats certain scarring lung diseases in adults. All the supported products are indicated for idiopathic pulmonary fibrosis (IPF) and for chronic fibrosing interstitial lung diseases (ILDs) with a progressive phenotype (scarring lung disease that keeps getting worse).

Ofev, nintedanib capsules (100 mg and 150 mg) and one other nintedanib capsule product are also indicated to slow the decline in lung function in systemic sclerosis-associated interstitial lung disease (SSc-ILD). The nintedanib esylate capsule label lists only IPF and progressive chronic fibrosing ILDs.

Taking Branched-chain Amino Acids (bcaa) and Nintedanib Esylate Together: Common Questions

Is it safe to take Branched-chain Amino Acids (bcaa) with Nintedanib Esylate?
We do not list a known interaction between Branched-chain Amino Acids (bcaa) and Nintedanib Esylate. 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.
Do Branched-chain Amino Acids (bcaa) and Nintedanib Esylate have any of the same side effects?
Yes — our sources link each of them separately to 6 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Should I take Branched-chain Amino Acids (bcaa) and Nintedanib Esylate at the same time of day?
At least one FDA label for a product containing Nintedanib Esylate says to take it with food. If you take Branched-chain Amino Acids (bcaa) on an empty stomach out of habit, keep them separate and take Nintedanib Esylate with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Nintedanib Esylate products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the Branched-chain Amino Acids (bcaa) and Nintedanib Esylate combination checked?
Interactions in our licensed database are recorded against drug classes. Nintedanib Esylate is filed under 5 classifications, and Branched-chain Amino Acids (bcaa) has documented interactions with 2 drug classes — none of Nintedanib Esylate'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 Branched-chain Amino Acids (bcaa) interact with any other medications?
Yes. Branched-chain Amino Acids (bcaa) has 91 documented drug interactions in our database — Nintedanib Esylate 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 Nintedanib Esylate interact with any supplements?
Yes. Nintedanib Esylate has documented interactions with 285 supplements in our database — Branched-chain Amino Acids (bcaa) is not one of them. The Nintedanib Esylate interaction page linked on this page lists every one, ranked by severity.
