Potato + Levothyroxine
Levothyroxine brand names: Euthyrox, Levothroid, Unithroid, Synthroid, Levoxyl, and others.
We found no known interaction between Potato and Levothyroxine 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 Levothyroxine states a food rule worth keeping to, and 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.
Potato and Levothyroxine
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 Levothyroxine and Potato 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.
Potato 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 Levothyroxine
Interactions in our licensed database are recorded against drug classes, not just single drug names. Levothyroxine is filed under 3 classifications — including thyroid hormone, oral drugs. Potato has documented interactions with 2 drug classes — the most serious being succinylcholine (moderate) and thrombolytic drugs (moderate) — and none of Levothyroxine’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.
Potato Does Interact With Other Medications
Potato has 7 moderate known drug interactions in our database — Levothyroxine isn’t one of them. If you take anything else, check it against the full list below.

Potato in Pregnancy & Breastfeeding
When unblemished, ripe potatoes are used orally in food amounts. There is insufficient reliable information available about the safety of medicinal use of potato in pregnancy and lactation.

Some Levothyroxine Products Have a Food Rule — Potato Should Not Break It
At least one FDA label for a product containing Levothyroxine says to take it on an empty stomach. Most supplements — Potato included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Levothyroxine on its own and move Potato to a meal later in the day.
This may not be true of your version. Food instructions belong to the product, not the ingredient: two Levothyroxine 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.
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.
What Levothyroxine Is Prescribed For, and What Potato Has Been Studied For
These two come up together because they touch the same health topic — not because they do the same job. Levothyroxine is a prescription medicine with approved uses on its FDA label. Potato is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.
Levothyroxine is prescribed for: Levothyroxine replaces or supplements the thyroid hormone your body isn't making enough of. It's used for hypothyroidism — an underactive thyroid — in adults, children, and even newborns, whether the cause is the thyroid gland itself, the pituitary gland, or the hypothalamus in the brain. It's also used alongside surgery and radioiodine treatment in people with certain types of thyroid cancer, to help suppress the hormone that can stimulate cancer growth. It is not meant for weight loss, treating benign thyroid nodules in people who have enough iodine, or for hypothyroidism during recovery from a temporary condition called subacute thyroiditis.

Cancer studied, not established Potato has been studied for this. Natural Medicines rates the evidence: Possibly Ineffective Read what the research shows
Potato for cancer
A meta-analysis of 7 observational studies shows that potato consumption is not associated with a reduced risk of cancer-related death. A meta-analysis of 56 studies shows that total daily potato intake is not associated with the overall incidence of cancer, and also is not associated with the incidence of cancers of the gastrointestinal tract, colon, rectum, pancreas, stomach, breast, kidney, lung, or bladder.

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 Levothyroxine on your own; if you are taking Potato 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 Levothyroxine page
“Levothyroxine replaces a hormone your body measures in tiny amounts, so small shifts in its blood level show up in how you feel, and I treat this list with genuine care. Nearly everything on it does one of two things: blocks the pill from being absorbed in the gut, the way everyday minerals like calcium do by binding it into complexes,…”

About Potato
What is Potato?
- Digestive complaints and heartburn
- Minor skin irritation or burns (topical folk use)
- Joint or muscle aches (traditional poultice)
- Source of carbohydrates and potassium in the diet
- Eye puffiness (cosmetic folk use)
Potato is a common food, and as a supplement it is mostly used in folk remedies such as raw potato juice for stomach upset or as a topical poultice. Solid scientific evidence for these uses is very limited. The edible tuber is safe as food, but green, sprouted, or raw potato in large amounts can contain natural toxins, so use caution and talk to your pharmacist before using potato as a remedy.
Solanum tuberosum · Solanaceae · Tuber (and sometimes raw potato juice); leaves and sprouts are not used and can be toxic · Whole cooked potato (food), raw potato juice, topical poultice, starch
An interaction check asks whether these two react with each other — it does not ask whether Potato is a good idea for someone in your situation. Here is what our Potato record says about it on its own.
Potato: dosing
There is no established standardized dose of potato as a supplement or remedy. As a food, normal portions are part of a regular diet.For folk remedies like raw potato juice, no proven safe or effective dose exists.
