Drug & supplement interaction

Vitamin E + Semaglutide

Semaglutide brand names: Ozempic, Rybelsus, Wegovy.

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

We found no known interaction between Vitamin E and Semaglutide 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.

Vitamin E and Semaglutide

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 Semaglutide and Vitamin E 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.

Vitamin E safety at a glance

Vitamin E overall Use caution Usual dietary amounts are safe, but high-dose long-term supplements may raise the risk of bleeding and other harms.
Pregnancy Possibly Safe When used orally and appropriately. The tolerable upper intake level (UL) during pregnancy is 800 mg for those 14-18 years of age and 1000 mg for those 19 years... Read the full pregnancy detail
Breastfeeding Likely Safe When used orally in amounts that do not exceed the tolerable upper intake level (UL). The UL during lactation is 800 mg for those 14-18 years of age and 1000 mg... Read the full breastfeeding detail

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.

How we checked

Why No Interaction Is Listed for Semaglutide

Interactions in our licensed database are recorded against drug classes, not just single drug names. Semaglutide is filed under 2 classifications — antidiabetes drugs, oral drugs. Vitamin E has documented interactions with 8 drug classes — the most serious being alkylating agents (moderate), anticoagulant/antiplatelet drugs (moderate) and antitumor antibiotics (moderate) — and none of Semaglutide’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.

Keep it in perspective

What to actually watch for

No Interaction Found — But Data Suggests Vitamin E and Semaglutide May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. One of them is worth acting on rather than waiting out — marked below.

  • Raised blood pressure Worth acting on Additional detail

    Vitamin E

    “In an analysis of 3 trials, taking vitamin E 400 IU with vitamin C 1000 mg daily for 14-22 weeks during gestation appears to increase the risk of gestational hypertension by 30% compared to placebo in patients at risk of pre-eclampsia. However, the risk of pre-eclampsia itself was not increased.”

Special populations

Vitamin E in Pregnancy & Breastfeeding

Pregnancy Possibly Safe

When used orally and appropriately. The tolerable upper intake level (UL) during pregnancy is 800 mg for those 14-18 years of age and 1000 mg for those 19 years and older. However, maternal supplementation is not generally recommended unless dietary vitamin E falls below the RDA. No serious adverse effects were reported with oral intake of 400 IU per day starting at weeks 9-22 of pregnancy in healthy patients or those at high risk for pre-eclampsia, or with 600-900 IU daily during the last two months of pregnancy. However, some preliminary evidence suggests that taking vitamin E supplements might be harmful when taken in early pregnancy. A case-control study found that taking a vitamin E supplement during the first 8 weeks of pregnancy is associated with a 1.7-9-fold increase in odds of congenital heart defects. However, the exact amount of vitamin E consumed during pregnancy in this study is unclear. Until more is known, advise patients to avoid taking a vitamin E supplement in early pregnancy unless needed for an appropriate medical indication.

Lactation Likely Safe

When used orally in amounts that do not exceed the tolerable upper intake level (UL). The UL during lactation is 800 mg for those 14-18 years of age and 1000 mg for those 19 years and older.

Lactation Possibly Unsafe

When used orally in amounts that exceed the UL due to increased risk of adverse effects.

Overlapping uses

What Semaglutide Is Prescribed For, and What Vitamin E Has Been Studied For

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

Semaglutide is prescribed for: Semaglutide is available as Wegovy (injection and tablet) and Ozempic (injection), and each product has its own approved uses. Wegovy injection is approved — alongside diet and exercise — to reduce excess body weight in adults and in children aged 12 and older with obesity, to lower the risk of serious heart events (heart attack, stroke, or cardiovascular death) in adults with obesity or overweight who also have established heart disease, and for treatment of a liver condition called MASH (metabolic dysfunction-associated steatohepatitis, formerly called NASH) with moderate-to-advanced scarring in adults. Wegovy tablets share the cardiovascular risk reduction and weight management uses in adults, but are not approved for MASH or for use in children. Ozempic injection is approved to improve blood sugar control in adults with type 2 diabetes (alongside diet and exercise) and to reduce the risk of major cardiovascular events in adults with type 2 diabetes who also have established heart disease.

Read the rest of what Semaglutide is prescribed for

All forms are used alongside a reduced-calorie diet and increased physical activity. Ozempic is not approved for type 1 diabetes. The MASH approval for Wegovy injection is an accelerated approval, meaning continued approval may depend on results from a confirmatory study.

Vitamin E has been studied for:

  • Scarring studied, not established Vitamin E has been studied for this. Natural Medicines rates the evidence: Possibly Ineffective Read what the research shows

    Vitamin E for scarring

    Topical vitamin E does not seem to improve scar appearance.

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 Semaglutide on your own; if you are taking Vitamin E 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 Semaglutide page

“Semaglutide (Ozempic, Rybelsus, Wegovy) lowers blood sugar, and so do most of the 256 supplements on this page, which is why I read this list with real vigilance rather than a shrug. Nearly all of the entries either add to its glucose-lowering effect and raise the risk of hypoglycemia, or push sugar the other way and blunt it, as niaci…”

About Vitamin E

What is Vitamin E?

Vitamin E
  • General antioxidant support
  • Skin and hair care
  • Heart health
  • Eye health (age-related conditions)
  • Immune support

Vitamin E is an essential fat-soluble vitamin and antioxidant that most people get in adequate amounts from a normal diet. Supplements can help correct a true deficiency, but high-dose vitamin E has not been clearly proven to prevent heart disease or cancer and may carry risks. Talk to your pharmacist or doctor before taking high doses.

Vitamin E is a nutrient, not a plant part; it is found in plant oils, nuts, seeds, and leafy greens · Softgels, capsules, oral liquid, chewable tablets, topical oils and creams

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

Vitamin E: dosing

Vitamin E needs are usually met through a normal diet. There is a recommended daily intake set by health authorities, and there is also an upper limit for supplements that should not be exceeded without medical guidance, because higher amounts raise the risk of side effects.Because the right amount depends on your age, health, and diet, it is best to follow the product label and avoid high-dose products unless a healthcare provider recommends them.

Taking Vitamin E and Semaglutide Together: Common Questions

Is it safe to take Vitamin E with Semaglutide?
We do not list a known interaction between Vitamin E and Semaglutide. 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.
Do Vitamin E and Semaglutide have any of the same side effects?
Yes — our sources link each of them separately to 4 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Are Vitamin E and Semaglutide 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 Vitamin E in each. That is a conversation for your prescriber, especially if Semaglutide is being adjusted to a target.
How was the Vitamin E and Semaglutide combination checked?
Interactions in our licensed database are recorded against drug classes. Semaglutide is filed under 2 classifications, and Vitamin E has documented interactions with 8 drug classes — none of Semaglutide's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Vitamin E interact with any other medications?
Yes. Vitamin E has 764 documented drug interactions in our database — Semaglutide is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Semaglutide interact with any supplements?
Yes. Semaglutide has documented interactions with 256 supplements in our database — Vitamin E is not one of them. The Semaglutide interaction page linked on this page lists every one, ranked by severity.
