HelloPharmacist Scorecard of Zymex by SP Standard Process

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

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 1 of its 7 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (1,680 mg) without saying how much of each component you get.

Zymex contains 7 ingredients, with calcium as the primary active component. The product also includes beet and date palm as active ingredients.

Calcium is included for its established role in supporting bone health and helping maintain healthy calcium levels in the body. Beet is present for its potential effects on exercise performance and muscle soreness.

Date palm rounds out the active lineup. The remaining ingredients — lactose, a proprietary blend, whey, defatted wheat, and enzymatically processed Tillandsia usneoides — appear to be supporting or processing agents.

The product also contains inactive ingredients including honey, calcium lactate, and calcium stearate.

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

This product doesn't appear to be marketed for a specific use, so we graded its ingredients' overall clinical evidence instead.

Strong

Strong clinical evidence supports its ingredients for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredients' overall clinical evidence instead.
  • On file: Hyperkalemia — rated "Effective" (Calcium) (Natural Medicines).
  • On file: Dyspepsia — rated "Effective" (Calcium) (Natural Medicines).
  • On file: Hypocalcemia — rated "Effective" (Calcium) (Natural Medicines).
  • On file: Kidney failure — rated "Effective" (Calcium) (Natural Medicines).
  • On file: Corticosteroid-induced osteoporosis — rated "Likely Effective" (Calcium) (Natural Medicines).

Calcium in this product is effective for kidney failure, dyspepsia (indigestion), low blood calcium (hypocalcemia), high potassium levels (hyperkalemia), and is likely effective for osteoporosis. Beet has possibly effective evidence for athletic performance and exercise-induced muscle soreness, though evidence for its effects on chronic obstructive pulmonary disease is possibly ineffective.

The evidence isn't established in the data we hold for beet's effects on cholesterol levels or cognitive function. Date palm's effectiveness for aging skin, mouth sores, labor induction, and pre-eclampsia has insufficient reliable evidence to rate.

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 4 of the 4 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 4 of 4.
  • General safety write-ups exist for 4 of 4.
  • 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, but high amounts can cause problems. The most common side effects from oral calcium are belching, constipation, diarrhea, bloating, and stomach upset.

Rarely, case reports have raised concerns about a serious skin and soft-tissue condition (calciphylaxis) and kidney stones. There is some concern that very high doses — over 1,500 to 2,000 mg daily — might increase the risk of advanced prostate cancer and possibly cardiovascular disease, though research on this is mixed and has been criticized.

Beet is generally well tolerated as a food; concentrated supplements lack complete safety data, so use caution. Common side effects are red or black stools, which are harmless.

Rarely, large amounts might cause low blood calcium (hypocalcemia) or kidney damage. Calcium is likely safe in pregnancy at recommended amounts and possibly unsafe above that; stay within recommended intake unless your doctor advises otherwise.

During breastfeeding, adequate calcium can be met with recommended amounts — check with your provider. We hold no pregnancy or breastfeeding data for beet, whey, defatted wheat, or the processed Tillandsia usneoides.

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

Why this rating?
  • 3 of the 4 matched ingredients can interact with medications — Beet, Calcium, Whey Protein.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: heart-rhythm medications; lithium; Parkinson's medications.
  • For scale: 947 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.

Before taking Zymex, check your medications against these types: HIV integrase inhibitors like dolutegravir and elvitegravir (Major — timing needed), intravenous ceftriaxone (Major — must separate by 48 hours), levothyroxine and other thyroid drugs (Moderate — separate doses by 4 hours), sotalol and other heart rhythm drugs (Moderate), diltiazem and other calcium-channel blockers (Moderate), raltegravir (Moderate), and drugs that depend on liver enzymes CYP3A4 or CYP1A2 (Moderate to Minor with beet). If you take any of these, run them through the interaction checker below.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with strong clinical evidence behind its ingredients' uses. Major medication interactions have been identified, and safety information is well characterized.

This product's calcium can support bone health and correct low calcium levels, and beet may help with exercise performance. However, if you take levothyroxine, certain HIV medications, sotalol, or intravenous ceftriaxone, you'll need to talk with your pharmacist about timing or whether this is right for you.

Each ingredient & the kinds of drugs it affects

For each ingredient in Zymex 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.

Beet3 drug types · 861 drugs

Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, beet might increase the levels of CYP3A4 substrates.
In vitro research suggests that betanin, the major pigment in beet, competitively inhibits CYP3A4 in a dose-dependent manner similarly to strong CYP3A4 inhibitor ketoconazole.

Likelihood Possible Evidence D
Antihypertensive Drugs

Beet and beetroot contain nitrates, which can cause vasodilation, potentially leading to lower blood pressure. However, a study published in the European Journal of Clinical Nutrition using concentrated beetroot juice found no significant impact on blood pressure or heart rate in different age groups. Other small clinical studies suggest that while beet consumption might transiently lower blood pressure due to vessel dilation, there's no consistent evidence of a lasting effect. Overall, the theoretical risk of reduced blood pressure due to beet's nitrate content exists, but studies generally indicate a low and temporary impact rather than a sustained decrease.

Likelihood Possible Evidence A
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, beet might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research suggests that beet induces CYP1A2 enzymes.

Likelihood Possible Evidence D
Beet full monograph & interactions

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

Whey4 drug types · 53 drugs

Levodopa

Theoretically, whey protein might decrease levodopa absorption.
Small clinical studies show that concomitant ingestion of protein or high doses of leucine or isoleucine (100 mg/kg) and levodopa can exacerbate tremor, rigidity, and the "on-off" syndrome in patients with Parkinson disease.

Likelihood Probable Evidence D
Bisphosphonates

Theoretically, whey protein might reduce the absorption of bisphosphonates.
Whey protein contains minerals such as calcium that bind bisphosphonates in the gut. Advise patients to take bisphosphonates at least 30 minutes before whey protein, but preferably at a different time of day.

Likelihood Probable Evidence D
Quinolone Antibiotics

Theoretically, whey protein might decrease quinolone absorption.
Whey protein contains minerals, such as calcium, that can bind to quinolones in the gut. To avoid this interaction, advise patients to take oral quinolones at least 2 hours before or 4-6 hours after whey protein.

Likelihood Probable Evidence D
Tetracycline Antibiotics

Theoretically, whey protein might decrease tetracycline absorption.
Whey protein contains minerals, such as calcium, that bind to tetracyclines in the gut. To avoid this interaction, advise patients to take oral tetracyclines at least 2 hours before or 4-6 hours after whey protein.

Zymex by SP Standard Process: Common Questions

Does Zymex by SP Standard Process interact with any medications?
Yes. Based on its ingredients, Zymex has a known interaction with 946 medications, including 12 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Zymex contains 8 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.
What is calcium in Zymex used for?
Calcium supports bone health and helps prevent osteoporosis, and it's effective for correcting low blood calcium, kidney failure, and indigestion. It also helps regulate potassium levels in your body.
What does the beet in this product do?
Beet may help with athletic performance and reduce exercise-induced muscle soreness, though the evidence is still emerging. It's included as an active ingredient, not just a filler.
Will this cause constipation?
Constipation is one of the most common side effects of oral calcium supplements. Other common ones are belching, diarrhea, bloating, and stomach upset — reactions vary by person. Starting with a smaller amount or taking it with food may help.
Is this safe to take during pregnancy?
Calcium is likely safe during pregnancy at recommended amounts, but should not exceed your doctor's recommended intake without their guidance. The pregnancy and breastfeeding safety data we hold covers only calcium — ask your pharmacist or doctor about the other ingredients in this specific product for personalized advice.
Can I take this if I have prostate cancer concerns?
Calcium at very high doses — over 1,500 to 2,000 mg daily — has been linked in some research to increased prostate cancer risk, especially advanced forms. If you have a personal or family history of prostate cancer, discuss your calcium intake and this product with your doctor.
What are the red or black stools I've heard about?
Beet can cause red or black stools, which is harmless discoloration and not a sign of bleeding. It's a normal response to the pigments in beet and will pass on its own.
