The bottom line No known interaction

We found no known interaction between Amino Acid Therapy and lubiprostone 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 lubiprostone states a food rule worth keeping to.

Interaction report

Amino Acid Therapy and lubiprostone

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 lubiprostone and Amino Acid Therapy 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Amino Acid Therapy at all — not against lubiprostone, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

Amino Acid Therapy safety at a glance

Amino Acid Therapy overall Use caution Most amino acids are reasonably safe in food amounts, but high-dose supplements should be used carefully.

Pregnancy Use caution A balanced diet provides amino acids; high-dose supplements during pregnancy are not well studied, so avoid unless advised by a doctor.

Breastfeeding Use caution Safety of high-dose amino acid supplements while breastfeeding is not well established, so use caution.

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

What to actually watch for

What lubiprostone’s Own FDA Label Lists

This is not an interaction — none of it involves Amino Acid Therapy. These are the most notable effects listed in the ADVERSE REACTIONS section of lubiprostone’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 2 of them are worth acting on rather than waiting out — marked below.

Fainting Worth acting on
Shortness of breath Worth acting on
Bloating or gas
Low blood pressure
Constipation
Swelling
Stomach pain
Diarrhea
Vomiting
Headache

Showing the 10 most notable of 11 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for lubiprostone. Read the label on DailyMed › Amino Acid Therapy’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Amino Acid Therapy side to compare — that is a limit of the record, not a statement that Amino Acid Therapy has no side effects.

How to take them

Some lubiprostone Products Have a Food Rule — Amino Acid Therapy Should Not Break It

At least one FDA label for a product containing lubiprostone says to take it with food. If you take Amino Acid Therapy on an empty stomach out of habit, keep them separate — and take lubiprostone 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 lubiprostone 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.

Administration Instructions ( 2.2 ) • Swallow capsules whole and do not break apart or chew, • Take capsules with food and water, • Assess periodically the need for continuous therapy.

From the Dosage and Administration section of the FDA label we read for lubiprostone — 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.

Everything else you take

See Every Supplement That Interacts With lubiprostone

This page covers Amino Acid Therapy only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the lubiprostone page lists 17 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Coffee Charcoal (moderate), European Mandrake (moderate), Glucomannan (moderate) and Guar Gum (moderate).

By severity: 1 major · 7 moderate · 9 minor.

From our pharmacist’s overview on the lubiprostone page

“Every one of the 17 supplements on this page can interact with lubiprostone (Amitiza), the capsule prescribed for chronic constipation, by changing how much of the drug your gut absorbs. That calls for real vigilance, because most are fiber and bulking products like psyllium and glucomannan, exactly what constipation patients often try…”

About Amino Acid Therapy

What is Amino Acid Therapy?

Muscle building and recovery
Mood and sleep support
Fatigue and energy
Nutritional support
Wound healing

Amino acid therapy means using individual amino acids (the building blocks of protein) as supplements to support muscle, mood, sleep, or general nutrition. Some specific amino acids have good evidence for certain uses, but the broad idea of treating many conditions with custom amino acid blends is not well proven. Talk to your pharmacist or doctor before starting, especially if you have kidney or liver problems.

Individual amino acids (building blocks of protein) · Capsules, tablets, powders, intravenous (IV) solutions, and protein-based supplements

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

Amino Acid Therapy: dosing

There is no single standard dose for "amino acid therapy," because the right amount depends on the specific amino acid and the reason you are taking it. Doses studied for one amino acid do not apply to others.The safest approach is to follow the directions on the product label and not exceed them. They can help you decide whether a supplement is appropriate and at what amount.

About Lubiprostone

What Is Lubiprostone Used For?

Brand name: Amitiza

Lubiprostone capsules are used to treat three types of constipation-related conditions in adults: chronic idiopathic constipation (CIC) — long-term constipation with no clear cause; opioid-induced constipation (OIC) — constipation caused by opioid pain medicines in adults with chronic non-cancer pain; and irritable bowel syndrome with constipation (IBS-C).

For OIC, lubiprostone has not been shown to work in people taking diphenylheptane opioids such as methadone. For IBS-C, approval is specifically for women 18 years of age and older. The brand Amitiza carries all three of these indications.
