The bottom line No known interaction

We found no known interaction between Collagen Type I (native) and Meclofenamate 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 Meclofenamate states a food rule worth keeping to.

Interaction report

Collagen Type I (native) and Meclofenamate

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 Meclofenamate and Collagen Type I (native) 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 Collagen Type I (native) at all — not against Meclofenamate, 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.

What to actually watch for

What Collagen Type I (native) Itself Has Been Linked To

This is not an interaction — nothing below involves Meclofenamate. It is the side-effect record for Collagen Type I (native) on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Collagen Type I (native), this list is the first place to look.

  • Stomach upset Additional detail

    “Orally, dyspepsia occurred in one patient in one clinical trial.”

Everything above comes from the Natural Medicines adverse-effect record for Collagen Type I (native) — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Meclofenamate’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Meclofenamate column appears here.

How to take them

Some Meclofenamate Products Have a Food Rule — Collagen Type I (native) Should Not Break It

At least one FDA label for a product containing Meclofenamate says to take it with food. If you take Collagen Type I (native) on an empty stomach out of habit, keep them separate — and take Meclofenamate 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 Meclofenamate 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.

If gastrointestinal complaints occur (see WARNINGS and PRECAUTIONS ), meclofenamate sodium may be administered with meals or with milk (see CLINICAL PHARMACOLOGY for a description of food effects).

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

Overlapping uses

What Meclofenamate Is Prescribed For, and What Collagen Type I (native) Has Been Studied For

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

Meclofenamate is prescribed for: Meclofenamate sodium capsules are used in adults to relieve mild to moderate pain, reduce fever, and treat the signs and symptoms of rheumatoid arthritis, osteoarthritis, juvenile arthritis, and ankylosing spondylitis (a type of spinal arthritis). They are also used for acute painful shoulder, acute gouty arthritis, primary dysmenorrhea (painful periods), and idiopathic heavy menstrual bleeding. This medication is not recommended for use in children, as adequate safety and effectiveness studies have not been carried out in that age group.

Collagen Type I (native) has been studied for:

  • Osteoarthritis studied, not established Collagen Type I (native) has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Collagen Type I (native) for osteoarthritis

    Oral collagen type I might have a moderate effect on pain and function in patients with osteoarthritis.

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 Meclofenamate on your own; if you are taking Collagen Type I (native) for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

From our pharmacist’s overview on the Meclofenamate page

“Meclofenamate (Meclomen) is a prescription NSAID for pain and arthritis, a class of drug that is already hard on the stomach and kidneys, so this list deserves real care rather than a quick skim. Five of its 32 supplement and herbal interactions rate major, clustered around two dangers: alcohol (beer and wine both raise the risk of sto…”

About Collagen Type I (native)

What is Collagen Type I (native)?

  • Skin health and wrinkles
  • Joint comfort and arthritis
  • Bone strength
  • Hair and nail support
  • Wound and tissue repair

Type I collagen is the most abundant protein in human skin, bones, and tendons, and it is sold as a supplement to support skin, joints, and bones. 'Native' (undenatured) Type I collagen keeps its natural triple-helix structure rather than being broken down into peptides. Early research is promising for skin and joints, but evidence is still limited, and most products are generally well tolerated.

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

Collagen Type I (native): dosing

There is no official standardized dose for native Type I collagen, and the right amount depends on the specific product. Doses used in studies vary widely depending on the form (powder versus tablet) and whether the collagen is native or hydrolyzed.The safest approach is to follow the directions on the product label and not exceed them.

Taking Collagen Type I (native) and Meclofenamate Together: Common Questions

Is it safe to take Collagen Type I (native) with Meclofenamate?
We do not list a known interaction between Collagen Type I (native) and Meclofenamate. 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 Collagen Type I (native) and Meclofenamate at the same time of day?
At least one FDA label for a product containing Meclofenamate says to take it with food. If you take Collagen Type I (native) on an empty stomach out of habit, keep them separate and take Meclofenamate with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Meclofenamate products can differ — so check the directions on your own box. This is about absorption, not an interaction.
Are Collagen Type I (native) and Meclofenamate 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. This page lists the shared uses and how strong the evidence is for Collagen Type I (native) in each. That is a conversation for your prescriber, especially if Meclofenamate is being adjusted to a target.
Does Meclofenamate interact with any supplements?
Yes. Meclofenamate has documented interactions with 32 supplements in our database — Collagen Type I (native) is not one of them. The Meclofenamate interaction page linked on this page lists every one, ranked by severity.
