HelloPharmacist Scorecard of Pyruvate 600 mg by NOW Sports
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
This product contains 2 active ingredients: pyruvate and calcium pyruvate (a calcium salt form of pyruvate). The capsules also contain inactive ingredients — hypromellose, hydroxypropyl cellulose, stearic acid, and silicon dioxide — which serve as binders and fillers to hold the capsule together.
Does it work?
Not established
For pyruvate, the evidence is mixed. It's rated possibly effective for weight loss (obesity) based on available studies.
For heart failure (congestive heart failure), high cholesterol (hyperlipidemia), and a skin condition called ichthyosis, the evidence is too thin — we rate it insufficient to say whether it works. Calcium itself is effective for kidney failure, upset stomach (dyspepsia), low blood calcium (hypocalcemia), high potassium levels (hyperkalemia), and likely effective for bone loss (osteoporosis).
How safe is it?
Well-documented data
Pyruvate is generally well tolerated in short studies, but high doses can cause digestive upset — bloating, diarrhea, flatulence, and loose stools are the main side effects. In one trial, nearly 6 in 10 people taking high-dose pyruvate reported diarrhea.
Pyruvate may also raise triglyceride (blood fat) levels. The safety data advises against pyruvate during pregnancy and breastfeeding because information is limited.
Calcium is safe at recommended doses, though very high amounts can cause constipation, diarrhea, stomach upset, and rarely kidney stones. Adequate calcium is important in pregnancy and breastfeeding — stay within recommended amounts and check with your provider.
There's some concern in research about very high calcium intake (over 1500–2000 mg daily) and prostate cancer risk, though the evidence is mixed and debated.
Meds to double-check
Major interaction found
Check with your pharmacist before taking this product if you're on dolutegravir (Tivicay) or elvitegravir (Vitekta) — these are Major interactions requiring careful dose spacing. Also flag ceftriaxone (Rocephin) if given intravenously, levothyroxine (Synthroid) for thyroid, sotalol (Betapace) for heart rhythm, raltegravir (Isentress), diltiazem (Cardizem), or calcipotriene (Dovonex).
The calcium in this product can reduce how your body absorbs or uses them.
The bottom line
Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Major medication interactions have been identified, and safety information is well characterized.
This product is mainly for people interested in pyruvate's possible role in weight management, combined with calcium for bone and digestive health. If you take HIV drugs (especially integrase inhibitors), thyroid medication, heart drugs, or antibiotics like ceftriaxone, you need to talk with your pharmacist before starting — spacing and timing matter.
Pregnant or breastfeeding? Skip the pyruvate part; the safety data isn't there.

Formula
Pyruvate, or pyruvic acid, is a biochemical compound that’s involved in a number of metabolic processes in the body, including the metabolism of fat, proteins, and carbohydrates, the storage of glycogen, and the production of cellular energy. Pyruvate is necessary for the citric acid cycle (or Krebs cycle), which is the process through which our cells produce energy in the form of adenosine triphosphate (ATP). ATP is the body’s primary chemical fuel and powers many vital functions, including energy production, muscle contraction, and cellular fuel replenishment.

Pyruvate 600 mg by NOW Sports Drug Interactions
HelloPharmacist Interaction Report
NOW Sports Pyruvate 600 mg contains calcium pyruvate, which interacts with several medications.
The most serious interaction is with the HIV integrase inhibitors dolutegravir (Tivicay) and elvitegravir (Vitekta) — both ranked Major severity. Calcium reduces levels of these drugs significantly; you'll need to space doses carefully (dolutegravir 2 hours before or 6 hours after; elvitegravir 2 hours before or after calcium).
There's also a Major-severity caution with ceftriaxone (Rocephin): intravenous calcium can cause dangerous precipitation in lungs and kidneys, so these shouldn't be used within 48 hours of each other.
Read the full breakdown — every affected drug type, severity by severity
Moderate interactions affect several other medications. Calcium reduces absorption of the thyroid drug levothyroxine (Synthroid) and the heart rhythm medication sotalol (Betapace) — both need spacing from calcium doses.
The HIV drug raltegravir (Isentress) may have reduced levels, though dose adjustment typically isn't needed. Calcium can also theoretically reduce the effect of the heart medication diltiazem (Cardizem) and increase the risk of high blood calcium (hypercalcemia) when combined with calcipotriene (Dovonex), a vitamin D analog for psoriasis.
Altogether, these interactions span 167 individual medications. Pyruvate itself has no documented interactions in our data.

For each ingredient in Pyruvate 600 mg with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Calcium
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
