Conjugated Linoleic Acid (cla) + Amitriptyline
Amitriptyline brand name: Elavil.
We found no known interaction between Conjugated Linoleic Acid (cla) and Amitriptyline 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 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.
Conjugated Linoleic Acid (cla) and Amitriptyline
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 Amitriptyline and Conjugated Linoleic Acid (cla) 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.
Conjugated Linoleic Acid (cla) safety at a glance
Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Why No Interaction Is Listed for Amitriptyline
Interactions in our licensed database are recorded against drug classes, not just single drug names. Amitriptyline is filed under 15 classifications — including tricyclic antidepressants (tcas), antidepressant drugs, cytochrome p450 2c19 (cyp2c19) substrates. Conjugated Linoleic Acid (cla) has documented interactions with 3 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), antihypertensive drugs (moderate) and ramipril (altace) (moderate) — and none of Amitriptyline’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.

About Conjugated Linoleic Acid (cla)
What is Conjugated Linoleic Acid (cla)?
- Weight loss
- Improving body composition
- Sports and muscle support
- Reducing inflammation
- General wellness
CLA is a fatty acid found naturally in meat and dairy, and supplements are usually made from safflower oil. While it is popular for fat loss and body composition, research results are mixed and any real-world effect appears small at best. It is likely safe for short-term use in most healthy adults, but talk to your pharmacist or doctor before starting it.
Fatty acid (often sourced from safflower or sunflower oil) · Softgels, capsules, oil
An interaction check asks whether these two react with each other — it does not ask whether Conjugated Linoleic Acid (cla) is a good idea for someone in your situation. Here is what our Conjugated Linoleic Acid (cla) record says about it on its own.
Conjugated Linoleic Acid (cla): dosing
There is no official or standardized dose of CLA. Doses used in studies have varied widely, and it is not clear which amount, if any, is most effective.The best approach is to follow the directions on the product label and not exceed the recommended amount.

About Amitriptyline
What Is Amitriptyline Used For?
Brand name: Elavil
Amitriptyline HCL and Amitriptyline Hydrochloride tablets are used to relieve symptoms of depression. Depression that originates from within the body (called endogenous depression) tends to respond better than other types of depression.
