Glycine + Captopril, Hydrochlorothiazide
Captopril, Hydrochlorothiazide brand names: Capozide, Acezide.
We found no known interaction between Glycine and Captopril, Hydrochlorothiazide 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.
Glycine and Captopril, Hydrochlorothiazide
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, Hydrochlorothiazide and Glycine 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.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Why No Interaction Is Listed for Captopril, Hydrochlorothiazide
Interactions in our licensed database are recorded against drug classes, not just single drug names. Captopril, Hydrochlorothiazide is filed under 9 classifications — including ace inhibitors (aceis), thiazide diuretics, diuretic drugs. Glycine has documented interactions with 1 drug class — the most serious being clozapine (clozaril) (moderate) — and none of Captopril, Hydrochlorothiazide’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 Captopril, Hydrochlorothiazide Is Prescribed For, and What Glycine Has Been Studied For
These two come up together because they touch the same health topic — not because they do the same job. Captopril, Hydrochlorothiazide is a prescription medicine with approved uses on its FDA label. Glycine is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.
Captopril, Hydrochlorothiazide is prescribed for: Captopril and hydrochlorothiazide tablets are used to treat high blood pressure (hypertension). The two ingredients work together to lower blood pressure more effectively than either one alone. This combination may be started as initial therapy or substituted when a patient has already been adjusted on both ingredients separately. It is approved for patients with normal kidney function, and is used more cautiously in those with impaired kidney function.

Stroke studied, not established Glycine has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows
Glycine for stroke
It is unclear if sublingual glycine is beneficial in patients with acute ischemic stroke.
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, Hydrochlorothiazide on your own; if you are taking Glycine for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Glycine
What is Glycine?
- Sleep quality and insomnia
- Relaxation
- Cognitive function
- Metabolic health
- General wellness
Glycine is a non-essential amino acid your body makes on its own and that also appears in protein-rich foods. It is most studied for improving sleep quality, where early research is promising but limited, and it appears generally well tolerated at common doses. Talk with your pharmacist or doctor before starting it, especially if you take other medicines or have a health condition.
Amino acid (made synthetically or by the body) · Powder, capsules, tablets
An interaction check asks whether these two react with each other — it does not ask whether Glycine is a good idea for someone in your situation. Here is what our Glycine record says about it on its own.
Glycine: dosing
There is no official standardized dose of glycine for any health condition. In sleep studies, a few grams taken before bedtime have been used, but the best dose for an individual is not established.The safest approach is to follow the directions on the product label and start with the lowest amount.
