Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 5 of its 5 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Para Thyrolate contains 5 active ingredients: calcium, papain, iodine, thyroid, and parathyroid. Calcium supports bone health and is used to correct low blood calcium (hypocalcemia).

Papain is a protein-digesting enzyme from papaya. Iodine is essential for thyroid function and is used to prevent iodine deficiency and radiation exposure.

Thyroid and parathyroid are glandular extracts. The product also contains gelatin, rice flour, and vegetable lubricant as inactive ingredients.

Does it work?

Strong evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Strong

Clinical evidence supports at least one of this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Thyroid gland support and function.
  • We looked for evidence on: Iodine deficiency, Hyperthyroidism, Hypocalcemia, Thyroid cancer, Thyroid storm, Hypothyroidism — and 3 related terms.
  • The strongest evidence on file: Calcium is rated "Effective" for Hypocalcemia (Natural Medicines).
  • Also on file: Iodine is rated "Likely Effective" for Iodine deficiency.
  • Also on file: Iodine is rated "Possibly Effective" for Thyroid storm.

Calcium is effective for kidney failure, indigestion (dyspepsia), low blood calcium (hypocalcemia), high potassium levels (hyperkalemia), and likely effective for osteoporosis. Iodine is likely effective for preventing iodine deficiency and protecting against radiation exposure, and possibly effective for mouth sores (oral mucositis) and gum disease (periodontitis).

Papain's effectiveness is not established in our data — the evidence for cancer, tooth decay, radiation skin damage, muscle soreness, shingles, and intestinal parasites is insufficient to rate.

The evidence, ingredient by ingredient Calcium Papain Iodine

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Calcium is generally well tolerated at recommended doses, though high amounts can cause problems. Common oral side effects include belching, constipation, diarrhea, gas, and stomach upset.

Rarely, very high doses have been linked to kidney stones and calciphylaxis (a serious calcification disorder). Some research suggests very high calcium intake (over 1500–2000 mg daily) may be associated with increased prostate cancer and cardiovascular disease risk, though these findings have limitations.

Iodine is well tolerated in normal dietary amounts but high doses can trigger thyroid problems, including goiter, hypothyroidism, or hyperthyroidism. Common side effects include nausea, diarrhea, headache, metallic taste, and rarely severe allergic reactions.

Papain is generally tolerated as a food, but concentrated supplements may irritate the digestive tract and cause allergic reactions in sensitive people; high doses have rarely caused severe gastritis or esophageal perforation. Pregnancy: calcium and iodine are likely safe at recommended amounts in pregnancy — adequate intake is important — but use only the amount your doctor advises and avoid high-dose products.

Papain is possibly unsafe in pregnancy; concentrated papain and unripe papaya should be avoided. Breastfeeding: calcium and iodine are safe at recommended amounts — though excess iodine can pass into breast milk — but follow medical guidance.

Papain has insufficient safety data in breastfeeding; supplemental papain is best avoided.

Known Interaction Concern · database check
Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 3 of the 3 matched ingredients can interact with medications — Iodine, Papain, Calcium.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; heart-rhythm medications; lithium.
  • For scale: 176 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

If you take dolutegravir or elvitegravir (HIV medications), ceftriaxone (an antibiotic), warfarin (a blood thinner), levothyroxine (thyroid hormone), sotalol (a beta-blocker), diltiazem (a heart drug), calcipotriene (for psoriasis), lithium (for mood), antithyroid drugs, or amiodarone (for heart rhythm), check with your doctor or pharmacist before taking this product — calcium, iodine, and papain each have documented interactions that may affect how these drugs work. The interaction severity ranges from Moderate to Major.

Each ingredient & the kinds of drugs it affects

For each ingredient in Para Thyrolate with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Calcium18 drug types · 168 drugs

Ceftriaxone (Rocephin)

Co-administration of intravenous calcium and ceftriaxone can result in precipitation of a ceftriaxone-calcium salt in the lungs and kidneys.
Avoid administering intravenous calcium in any form, such as parenteral nutrition or Lactated Ringers, within 48 hours of intravenous ceftriaxone. Case reports in neonates show that administering intravenous ceftriaxone and calcium can result in precipitation of a ceftriaxone-calcium salt in the lungs and kidneys. In several cases, neonates have died as a result of this interaction. So far there are no reports in adults; however, there is still concern that this interaction might occur in adults.

Likelihood Probable Evidence D
Dolutegravir (Tivicay)

Calcium seems to reduce levels of dolutegravir.
Advise patients to take dolutegravir either 2 hours before or 6 hours after taking calcium supplements. Pharmacokinetic research suggests that taking calcium carbonate 1200 mg concomitantly with dolutegravir 50 mg reduces plasma levels of dolutegravir by almost 40%. Calcium appears to decrease levels of dolutegravir through chelation.

Likelihood Probable Evidence B
Elvitegravir (Vitekta)

Calcium seems to reduce levels of elvitegravir.
Advise patients to take elvitegravir either 2 hours before or 2 hours after taking calcium supplements. Pharmacokinetic research suggests that taking calcium along with elvitegravir can reduce blood levels of elvitegravir through chelation.

Likelihood Probable Evidence B
Aluminum

Calcium citrate might increase aluminum absorption and toxicity. Other types of calcium do not increase aluminum absorption.
Calcium citrate can increase the absorption of aluminum when taken with aluminum hydroxide. The increase in aluminum levels may become toxic, particularly in individuals with kidney disease. However, the effect of calcium citrate on aluminum absorption is due to the citrate anion rather than calcium cation. Calcium acetate does not appear to increase aluminum absorption.

Likelihood Possible Evidence B
Bictegravir/Emtricitabine/Tenofovir Alafenamide (Biktarvy)

Calcium might decrease levels of bictegravir/emtricitabine/tenofovir alafenamide by reducing its absorption when taken in a fasting state.
Advise patients that bictegravir/emtricitabine/tenofovir alafenamide and calcium can be taken together if taken with food. However, if taken on an empty stomach, bictegravir/emtricitabine/tenofovir alafenamide should not be taken with, or 2 hours after, calcium containing products.

Likelihood Probable Evidence D
Bisphosphonates

Calcium reduces the absorption of bisphosphonates.
Advise patients to take bisphosphonates at least 30 minutes before calcium, but preferably at a different time of day. Calcium supplements decrease absorption of bisphosphonates.

Likelihood Probable Evidence C
Calcipotriene (Dovonex)

Taking calcipotriene with calcium might increase the risk for hypercalcemia.
Calcipotriene is a vitamin D analog used topically for psoriasis. It can be absorbed in sufficient amounts to cause systemic effects, including hypercalcemia. Theoretically, combining calcipotriene with calcium supplements might increase the risk of hypercalcemia.

Likelihood Possible Evidence B
Digoxin (Lanoxin)

Using intravenous calcium with digoxin might increase the risk of fatal cardiac arrhythmias.
Hypercalcemia increases the risk of fatal cardiac arrhythmias with digoxin. However, one retrospective analysis of clinical data suggests that intravenous calcium does not increase the risk of dysrhythmias or mortality in patients receiving digoxin.

Likelihood Possible Evidence B
Diltiazem (Cardizem, Others)

Theoretically, calcium may reduce the therapeutic effects of diltiazem.
Hypercalcemia can reduce the effectiveness of verapamil in atrial fibrillation. Theoretically, calcium might increase this risk of hypercalcemia and reduce the effectiveness of diltiazem.

Likelihood Probable Evidence D
Levothyroxine (Synthroid, Others)

Calcium seems to reduce the absorption and effectiveness of levothyroxine.
Advise patients to take levothyroxine and calcium supplements at least 4 hours apart. Calcium reduces levothyroxine absorption, probably by forming insoluble complexes. Calcium carbonate supplements reduce effectiveness of levothyroxine in patients with hypothyroidism.

Likelihood Probable Evidence B
Lithium

Theoretically, concomitant use of calcium and lithium may increase this risk of hypercalcemia.
Clinical research suggests that long-term use of lithium may cause hypercalcemia in 10% to 60% of patients. Theoretically, concomitant use of lithium and calcium supplements may further increase this risk.

Likelihood Possible Evidence B
Quinolone Antibiotics

Calcium seems to reduce the absorption of quinolone antibiotics.
Advise patients to take oral quinolones at least 2 hours before or 4-6 hours after calcium supplements or calcium-fortified foods. Taking calcium at the same time as oral quinolones can reduce quinolone absorption. Calcium binds to quinolones in the gut.

Likelihood Probable Evidence B
Raltegravir (Isentress)

Calcium may reduce levels of raltegravir.
Pharmacokinetic research shows that taking a single dose of calcium carbonate 3000 mg along with raltegravir 400 mg twice daily modestly decreases the mean area under the curve of raltegravir, but the decrease does not necessitate a dose adjustment of raltegravir. However, a case of elevated HIV-1 RNA levels and documented resistance to raltegravir has been reported for a patient taking calcium carbonate 1 gram three times daily plus vitamin D3 (cholecalciferol) 400 IU three times daily in combination with raltegravir 400 mg twice daily for 11 months. It is thought that calcium reduced raltegravir levels by chelation, leading to treatment failure.

Likelihood Possible Evidence B
Sotalol (Betapace)

Calcium seems to reduce the absorption of sotalol.
Advise patients to separate doses by at least 2 hours before or 4-6 hours after calcium. Calcium appears to reduce the absorption of sotalol, probably by forming insoluble complexes.

Likelihood Possible Evidence B
Tetracycline Antibiotics

Calcium seems to reduce the absorption of tetracycline antibiotics.
Advise patients to take oral tetracyclines at least 2 hours before, or 4-6 hours after calcium supplements. Taking calcium at the same time as oral tetracyclines can reduce tetracycline absorption. Calcium binds to tetracyclines in the gut.

Likelihood Probable Evidence C
Thiazide Diuretics

Taking calcium along with thiazides might increase the risk of hypercalcemia and renal failure.
Thiazides reduce calcium excretion by the kidneys. Using thiazides along with moderately large amounts of calcium carbonate increases the risk of milk-alkali syndrome (hypercalcemia, metabolic alkalosis, renal failure). Patients may need to have their serum calcium levels and/or parathyroid function monitored regularly.

Likelihood Probable Evidence C
Verapamil (Calan, Others)

Theoretically, calcium may reduce the therapeutic effects of verapamil.
Hypercalcemia can reduce the effectiveness of verapamil in atrial fibrillation. Theoretically, use of calcium supplements may increase this risk of hypercalcemia and reduce the effectiveness of verapamil.

Likelihood Probable Evidence D
Calcium Channel Blockers

Intravenous calcium may decrease the effects of calcium channel blockers; oral calcium is unlikely to have this effect.
Intravenous calcium is used to decrease the effects of calcium channel blockers in the management of overdose. Intravenous calcium gluconate has been used before intravenous verapamil (Isoptin) to prevent or reduce the hypotensive effects without affecting the antiarrhythmic effects. But there is no evidence that dietary or supplemental calcium when taken orally interacts with calcium channel blockers.

Likelihood Unlikely Evidence D
Calcium full monograph & interactions

Iodine3 drug types · 7 drugs

Amiodarone (Cordarone)

Combining iodine with amiodarone might cause excessively high iodine levels.
Amiodarone contains 37.3% iodine and can increase iodine levels. Concomitant use with iodine might increase the risk of having excessive iodine levels and adversely affecting thyroid function. Monitor thyroid function.

Likelihood Probable Evidence D
Antithyroid Drugs

Iodine might alter the effects of antithyroid drugs.
Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking iodine while using antithyroid drugs could alter the effects of the antithyroid drugs.

Likelihood Probable Evidence D
Lithium

Combining iodine with lithium might have additive hypothyroid effects.
Lithium can inhibit thyroid function. Several case reports suggest that concomitant use of lithium and potassium iodide can reduce thyroid function in otherwise healthy adults. Monitor thyroid function.

Likelihood Probable Evidence D
Iodine full monograph & interactions

Papain1 drug type · 2 drugs

Warfarin (Coumadin)

Theoretically, papain might increase the effects and side effects of warfarin.
In one case report, a patient previously stable on warfarin was found to have an international normalization ratio (INR) of 7.4, which was attributed to ingestion of a supplement containing papain from papaya extract.

Para Thyrolate by Progressive Professional from Progressive Laboratories: Common Questions

Does Para Thyrolate by Progressive Professional from Progressive Laboratories interact with any medications?
Yes. Based on its ingredients, Para Thyrolate has a known interaction with 176 medications, including 7 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Para Thyrolate contains 5 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I take Para Thyrolate if I'm pregnant or breastfeeding?
Calcium and iodine are likely safe in pregnancy and breastfeeding at recommended amounts — in fact, adequate intake is important — but use only the amount your doctor advises and avoid high-dose products. Iodine in excess can pass into breast milk. Papain, however, is possibly unsafe in pregnancy; concentrated papain and unripe papaya should be avoided, and supplemental papain has insufficient safety data in breastfeeding, so it's best avoided then. Talk with your doctor or pharmacist for personalized guidance.
What are the most common side effects of calcium in this product?
The most common side effects are belching, constipation, diarrhea, gas, and stomach upset. These tend to happen with oral calcium and are generally mild.
What is papain and does it actually work?
Papain is a protein-digesting enzyme from papaya. The evidence for its effectiveness — whether for cancer, tooth decay, muscle soreness, shingles, or intestinal parasites — is insufficient to rate. It's generally tolerated as a food, but concentrated supplements may irritate the digestive tract or cause allergic reactions in sensitive people.
Why can't calcium be taken at the same time as my levothyroxine?
Calcium forms insoluble complexes with levothyroxine, meaning they bind together and your body can't absorb the thyroid hormone properly. This reduces how well the medicine works. Taking them at least 4 hours apart prevents this problem.
Can I take this product if I'm on a blood thinner like warfarin?
Papain in this product has a documented Moderate interaction with warfarin — it may increase the blood-thinning effects and raise your bleeding risk. Additionally, calcium can theoretically interact with warfarin. You need to check with your doctor or pharmacist before starting this product if you take any blood thinner.
What side effects can iodine cause?
At normal amounts, iodine is well tolerated. Common side effects include nausea, diarrhea, headache, goiter (enlarged thyroid), metallic taste, and thyroid problems like hypothyroidism or hyperthyroidism. High doses have rarely caused severe allergic reactions. If you have a thyroid condition, talk with your doctor before taking supplemental iodine.
