Medically reviewed by · Updated June 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Diacylglycerol and Captopril 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.

Diacylglycerol and Captopril

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 Captopril and Diacylglycerol 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 Diacylglycerol at all — not against Captopril, 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 Captopril’s Own FDA Label Lists

This is not an interaction — none of it involves Diacylglycerol. These are the most notable effects listed in the ADVERSE REACTIONS section of Captopril’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. 10 of them are worth acting on rather than waiting out — marked below.

  • A stroke or mini-stroke Worth acting on
  • Bleeding in the gut Worth acting on
  • High potassium Worth acting on
  • Low sodium Worth acting on
  • Unsteadiness Worth acting on
  • A heart attack Worth acting on
  • Pancreatitis Worth acting on
  • Yellowing of the skin or eyes Worth acting on
  • Heart failure Worth acting on
  • Fainting Worth acting on

Showing the 10 most notable of 55 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 Captopril. Read the label on DailyMed › Where a percentage is shown, it is the share of 9,625 voluntary FDA FAERS reports for Captopril that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Diacylglycerol’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Diacylglycerol side to compare — that is a limit of the record, not a statement that Diacylglycerol has no side effects.

Overlapping uses

What Captopril Is Prescribed For, and What Diacylglycerol Has Been Studied For

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

Captopril is prescribed for: Captopril tablets are used to treat high blood pressure (hypertension), heart failure, and left ventricular dysfunction (weakened pumping function of the heart) in stable patients after a heart attack. For the heart attack indication, it helps improve survival and reduces the chance of developing full heart failure. Captopril tablets are also used to slow the progression of diabetic nephropathy (kidney damage caused by diabetes) in people with type 1 (insulin-dependent) diabetes who have retinopathy and significant protein in their urine. It reduces the risk of the kidneys failing to the point of needing dialysis or a transplant.

Diacylglycerol has been studied for:

  • Diabetes studied, not established Diacylglycerol has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Diacylglycerol for diabetes

    Most clinical research suggests that oral diacylglycerol does not improve glycemic control in adults with type 2 diabetes. However, it may modestly reduce triglyceride levels in some people.

  • Diabetic nephropathy studied, not established Diacylglycerol has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Diacylglycerol for diabetic nephropathy

    It is unclear if oral diacylglycerol can slow the progression of nephropathy in adults with diabetes.

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 Captopril on your own; if you are taking Diacylglycerol 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 Captopril page

“Anyone taking captopril (Capoten), an ACE inhibitor for high blood pressure and heart failure, should treat this list with genuine care rather than a quick skim. Most of the ingredients here act on blood pressure itself, some dropping it lower than intended and others, tyramine among them, pushing it back up and working against the med…”

  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Diacylglycerol is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).

About Diacylglycerol

What is Diacylglycerol?

  • Weight management
  • Reducing body fat
  • Lowering blood triglycerides
  • Healthy cooking oil substitute

Diacylglycerol (DAG) is a type of fat found naturally in small amounts in many edible oils and was once sold as a specialty cooking oil marketed for weight and fat management. Evidence for meaningful weight-loss benefits over regular cooking oils is weak and mixed, and one major DAG oil product was pulled from the market over a processing-related contaminant concern. Talk with your pharmacist or doctor before relying on it for any health purpose.

Edible oil component (derived from vegetable oils such as soybean and rapeseed) · Cooking oil, salad dressings, and processed food products

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

Diacylglycerol: dosing

There is no established or standardized dose of diacylglycerol for any health benefit. When sold as a cooking oil, it was simply used in place of regular oil in everyday cooking.If you come across a diacylglycerol product, follow the label directions and do not assume that using more will give you any extra benefit.

Taking Diacylglycerol and Captopril Together: Common Questions

Is it safe to take Diacylglycerol with Captopril?
We do not list a known interaction between Diacylglycerol and Captopril. 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.
Are Diacylglycerol and Captopril 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 Diacylglycerol in each. That is a conversation for your prescriber, especially if Captopril is being adjusted to a target.
Does Captopril interact with any supplements?
Yes. Captopril has documented interactions with 166 supplements in our database — Diacylglycerol is not one of them. The Captopril interaction page linked on this page lists every one, ranked by severity.
