The bottom line No known interaction

We found no known interaction between Body Protective Compound 157 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.

Body Protective Compound 157 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 Body Protective Compound 157 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 Body Protective Compound 157 at all — not against Levothyroxine, 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 Levothyroxine’s Own FDA Label Lists

This is not an interaction — none of it involves Body Protective Compound 157. These are the most notable effects listed in the ADVERSE REACTIONS section of Levothyroxine’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 change in thyroid levels Worth acting on
  • Bone thinning Worth acting on
  • Muscle weakness Worth acting on
  • A heart attack Worth acting on
  • Heart failure Worth acting on
  • Wheezing Worth acting on
  • Seizures Worth acting on
  • Chest pain Worth acting on
  • Shortness of breath Worth acting on
  • A severe allergic reaction Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Levothyroxine. Read the label on DailyMed › Body Protective Compound 157’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Body Protective Compound 157 side to compare — that is a limit of the record, not a statement that Body Protective Compound 157 has no side effects.

How to take them

Some Levothyroxine Products Have a Food Rule — Body Protective Compound 157 Should Not Break It

At least one FDA label for a product containing Levothyroxine says to take it on an empty stomach. Most supplements — Body Protective Compound 157 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 Body Protective Compound 157 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.

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 Body Protective Compound 157

What is Body Protective Compound 157?

Body Protective Compound 157

  • Gut healing and inflammation
  • Wound healing
  • General tissue repair and recovery

BPC 157 is a synthetic peptide that has shown promising healing effects in animal and laboratory studies, but it has not been proven safe or effective in well-designed human trials. It is not an approved drug or a legal dietary supplement in many places, so we cannot recommend it; talk to your doctor or pharmacist before considering it.

Synthetic peptide (a lab-made chain of 15 amino acids based on a sequence found in human gastric juice) · Injectable solution, oral capsules, nasal sprays, and topical preparations sold as research chemicals or compounded products

An interaction check asks whether these two react with each other — it does not ask whether Body Protective Compound 157 is a good idea for someone in your situation. Here is what our Body Protective Compound 157 record says about it on its own.

Body Protective Compound 157: dosing

There is no established, scientifically validated dose for BPC 157 in humans. Because it has not gone through proper clinical testing, no health authority has set a safe or effective amount.Doses suggested on websites and forums are not backed by solid human research, and we will not list specific amounts because doing so could imply they are safe or proven.

About Levothyroxine

What Is Levothyroxine Used For?

Brand names: Euthyrox, Levothroid, Unithroid, Synthroid, Levoxyl, Levo-T, Eltroxin, Estre, Levothyroxine, Novothyrox, Levolet

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.

Taking Body Protective Compound 157 and Levothyroxine Together: Common Questions

Is it safe to take Body Protective Compound 157 with Levothyroxine?
We do not list a known interaction between Body Protective Compound 157 and Levothyroxine. 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.
Should I take Body Protective Compound 157 and Levothyroxine at the same time of day?
At least one FDA label for a product containing Levothyroxine says to take it on an empty stomach, and supplements are usually taken with a meal — so taking them together at breakfast is the easy mistake. Where that applies, keep Levothyroxine on its own and move Body Protective Compound 157 to a meal later in the day. Food instructions belong to the product rather than the ingredient, so check the directions on your own box. This is about absorption, not an interaction.
Does Levothyroxine interact with any supplements?
Yes. Levothyroxine has documented interactions with 50 supplements in our database — Body Protective Compound 157 is not one of them. The Levothyroxine interaction page linked on this page lists every one, ranked by severity.
