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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

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 0 of its 4 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (1,000 mg) without saying how much of each component you get.

Zymex contains 4 active ingredients blended together: carrot, organic beet, rice, and enzymatically processed Spanish moss. Carrot is a source of vitamin A, while beet contains betalains and nitrates thought to support circulation and exercise recovery.

The product is filled into gelatin capsules with water and calcium stearate as inactive ingredients.

Does it work?

Moderate 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.

Moderate

Some 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: Athletic performance — rated "Possibly Effective" (Beet) (Natural Medicines).
  • On file: Exercise-induced muscle soreness — rated "Possibly Effective" (Beet) (Natural Medicines).
  • On file: Vitamin A deficiency — rated "Possibly Effective" (Carrot) (Natural Medicines).

The evidence is mixed and limited. Beet shows possibly effective evidence for athletic performance and exercise-induced muscle soreness — meaning some studies support it, but more research is needed.

The data doesn't establish that beet helps with COPD or that it affects cholesterol or brain function one way or another. Carrot is possibly effective for vitamin A deficiency; for cancers and fibromyalgia, there isn't enough reliable evidence to say either way.

Evidence for rice and Spanish moss isn't established in the data we hold.

The evidence, ingredient by ingredient Carrot Beet

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Carrot and beet are both generally well tolerated when eaten as foods. As concentrated supplements in this product, they're less studied, so use some caution.

A small number of people are allergic to carrot — allergic reactions can include hives, swelling, asthma, or diarrhea. Beet commonly causes harmless red or dark-colored stools.

In rare cases, very large amounts of beet have been linked to low blood calcium (hypocalcemia) and kidney damage. There isn't enough data on concentrated beet supplements during pregnancy or breastfeeding; carrot concentrates are also not well studied in those periods, though eating carrot as a food is fine.

Side effects, ingredient by ingredient Carrot Beet

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 2 matched ingredients can interact with medications — Beet.
  • The most serious interaction on file is rated Moderate.
  • For scale: 862 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, double-check any medications metabolized through CYP3A4 substrates (your pharmacist can tell you if yours are) — beet can moderately increase their blood levels. Also check blood pressure medications, as beet's nitrates may lower your pressure further.

A smaller concern: ask if you take any CYP1A2 substrates, since beet may theoretically weaken them.

The bottom line

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

Zymex is worth asking your pharmacist about if you take any regular medications — especially blood pressure drugs, statins, or anything metabolized by CYP3A4. If you're pregnant, breastfeeding, or allergic to carrot, talk with your pharmacist or doctor first.

organic 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.

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 861 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Zymex contains 4 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.
Will Zymex help my athletic performance?
Beet, one of the active ingredients, shows possibly effective evidence for athletic performance and exercise-induced muscle soreness. That means some studies support it, but the evidence isn't definitive yet. Talk to your pharmacist about whether it's a fit for your goals.
Can I take Zymex if I'm pregnant or breastfeeding?
The safety data isn't clear enough to say either way for the concentrated beet and carrot in this supplement. Eating carrot as a food is fine during both pregnancy and breastfeeding, but concentrated supplements haven't been well studied. Talk with your doctor or pharmacist for personalized advice.
Why are my stools red or dark after taking this?
That's beet. Red or dark-colored stools are a normal, harmless side effect of beet supplements and don't mean anything is wrong. It should resolve once you stop taking the product.
Is anyone allergic to Zymex?
A small number of people are allergic to carrot. Allergic reactions can include hives, swelling of the throat, asthma, or diarrhea. If you've had a carrot allergy before, skip this product and talk to your pharmacist about alternatives.
Does Zymex contain any fillers?
The product contains gelatin, water, and calcium stearate as inactive ingredients — these are binders and capsule materials. The four active ingredients are carrot, beet, rice, and Spanish moss.
