HelloPharmacist Scorecard of CLM by Loomis Enzymes

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

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 5 of its 12 active ingredients.
  • “Proprietary Enzyme Blend” is a proprietary blend — the label gives one combined amount (40 mg) without saying how much of each component you get.

CLM contains 12 ingredients total: digestive enzymes Amylase, Protease, Lipase, Cellulase, Glucoamylase, Hemicellulase, and Alpha-Galactosidase that are meant to break down fats, proteins, and carbohydrates in food. It also includes a proprietary enzyme blend, plus herbal extracts for their traditional wellness effects: Hops Flower, Chamomile, Valerian Root, Passionflower, and Lemon Balm.

The inactive ingredients are cellulose (a plant fiber), water, and phytase.

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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: pH balance and digestive support.
  • We looked for evidence on: Anxiety, Dyspepsia, Flatulence, Insomnia, Generalized anxiety disorder (GAD), Acid-base balance — and 1 related terms.
  • The strongest evidence on file: Valerian is rated "Possibly Effective" for Insomnia (Natural Medicines).
  • Also on file: Passion Flower is rated "Possibly Effective" for Pre-procedural anxiety, Insomnia.
  • Also on file: Lipase is rated "Insufficient Reliable Evidence To Rate" for Dyspepsia.

Evidence for the digestive enzymes—Lipase, Protease, and others—is not established in our data for the conditions listed (inflammatory bowel disease, indigestion). The herbal ingredients have varying support: Valerian Root is rated Possibly Effective for insomnia, and Passionflower is Possibly Effective for both insomnia and pre-procedural anxiety.

Lemon Balm is Possibly Effective for cold sores, stress, and depression. Hops Flower, Chamomile, and the remaining enzyme claims lack sufficient 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 7 of the 7 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 7 of 7.
  • General safety write-ups exist for 7 of 7.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Protease and Lipase are generally well tolerated, though people with serious digestive conditions should use them only under medical guidance. Rare occupational exposure to airborne protease has caused allergic reactions in workers.

The herbal ingredients are generally well tolerated short-term in most healthy adults but carry safety concerns: Chamomile can trigger allergic reactions in people sensitive to ragweed and related plants, and occupational exposure to chamomile dust has caused severe respiratory symptoms. Valerian may cause dizziness, drowsiness, vivid dreams, and withdrawal symptoms if stopped abruptly after long-term use.

Passionflower and Lemon Balm can cause drowsiness; one case report linked a passion flower product to severe nausea, vomiting, and heart rhythm abnormalities. For pregnancy and breastfeeding: Protease and Lipase lack sufficient safety data and are not recommended without medical advice.

Chamomile, Valerian, Passionflower, and Lemon Balm are all advised against in pregnancy due to insufficient data or possible uterine effects; breastfeeding safety is similarly unknown or not recommended without checking with your doctor first.

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?
  • 5 of the 7 matched ingredients can interact with medications — Lemon Balm, Hops, Valerian, Passion Flower, German Chamomile.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 1,018 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 CLM, check with your pharmacist if you use Warfarin or other blood thinners (Moderate risk), CNS depressants like benzodiazepines or sleep aids (Moderate risk from four herbal ingredients), estrogens or hormone replacement therapy (Moderate risk from Hops and Chamomile), contraceptives (Moderate risk from Chamomile), alprazolam (Xanax) (Moderate risk from Valerian), or alcohol with sedative intent (Moderate risk from Valerian). Additionally, Passionflower and Lemon Balm carry Minor interactions with drugs metabolized through CYP3A4, and Hops with CYP1A2 and CYP3A4 substrates.

No interactions are documented for the digestive enzymes we could check.

Likelihood Possible Evidence D
Contraceptive Drugs

Theoretically, large amounts of German chamomile might reduce the effectiveness of oral contraceptives.
In vitro, German chamomile has demonstrated antiestrogenic activity. Theoretically, concomitant use of large amounts of German chamomile might interfere with contraceptive drugs through competition for estrogen receptors.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, German chamomile might inhibit CYP2C9 and increase levels of drugs metabolized by these enzymes.
In vitro evidence shows that German chamomile might inhibit CYP2C9. So far, this interaction has not been reported in humans. However, there might be an increase in the levels of drugs metabolized by CYP2C9 in patients taking German chamomile.

Likelihood Possible Evidence D
Cytochrome P450 2D6 (Cyp2D6) Substrates

Theoretically, German chamomile might inhibit CYP2D6 and increase levels of drugs metabolized by these enzymes.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, German chamomile might inhibit CYP3A4 and increase levels of drugs metabolized by these enzymes.
In vitro evidence shows that German chamomile might inhibit CYP3A4. So far, this interaction has not been reported in humans. However, there might be an increase in the levels of drugs metabolized by CYP3A4 in patients taking German chamomile.

Likelihood Possible Evidence D
Estrogens

Theoretically, large amounts of German chamomile might reduce the effectiveness of estrogens.
In vitro, German chamomile has demonstrated antiestrogenic activity. Theoretically, large amounts of German chamomile might interfere with hormone replacement therapy through competition for estrogen receptors.

Likelihood Possible Evidence D
Tamoxifen (Nolvadex)

Theoretically, large amounts of German chamomile might interfere with the activity of tamoxifen.
In vitro, German chamomile has demonstrated antiestrogenic activity.

Likelihood Possible Evidence D
Warfarin (Coumadin)

German chamomile might increase the effects of warfarin and increase the risk of bleeding.
In one case, a 70-year-old female taking warfarin developed retroperitoneal hematoma and bilateral recti muscle bleeding along with an INR of 7.9 following ingestion of German chamomile tea 4-5 cups daily and use of a topical chamomile-based lotion applied 4-5 times daily.

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

Theoretically, German chamomile might inhibit CYP1A2 and increase levels of drugs metabolized by these enzymes.
In vitro and animal research shows that German chamomile might inhibit CYP1A2. So far, this interaction has not been reported in humans. However, there might be an increase in the levels of drugs metabolized by CYP1A2 in patients taking German chamomile.

Likelihood Possible Evidence D

Valerian Root Extract6 drug types · 902 drugs

Alcohol (Ethanol)

Valerian can have additive sedative effects when used concomitantly with alcohol.
Valerian has sedative effects. Theoretically, valerian might have an additive sedative effect when combined with alcohol. Excessive sedation has been reported in an alcohol-abusing individual who took valerian and Gingko biloba. However, the potential interaction between valerian and alcohol has been disputed in other research. Limited evidence suggests that a combination of valerian 160 mg and lemon balm 80 mg (Euvegal) does not cause further deterioration in reaction ability and reaction rate when taken with alcohol as compared to the effects of alcohol alone.

Likelihood Possible Evidence B
Alprazolam (Xanax)

Valerian can have additive sedative effects when used with alprazolam. Also, valerian in high doses might modestly increase alprazolam levels, though this is not likely to be clinically significant.
Valerian has sedative effects. Theoretically, valerian might cause additive sedation when combined with alprazolam. Also, a small pharmacokinetic study shows that taking valerian extract 1000 mg daily (providing 11 mg valerenic acid) might increase alprazolam levels by about 19%. This might be due to valerian's mild inhibition of cytochrome P450 3A4 (CYP3A4). Despite being statistically significant, this increase is not likely to be clinically significant.

Likelihood Possible Evidence B
Cns Depressants

Valerian can have additive sedative effects when used concomitantly with CNS depressant drugs.
Theoretically, concomitant use of valerian and drugs with sedative and anesthetic properties may cause additive therapeutic and adverse effects.

Likelihood Possible Evidence D
Glucuronidated Drugs

Valerian might weakly inhibit glucuronidation and increase concentrations of drugs metabolized by UGT1A1 and UGT2B7.
In vitro research shows that methanolic valerian extract and valerenic acid might competitively inhibit UDP-glucuronosyltransferase (UGT) 1A1 (UGT1A1) and UGT2B7.

Likelihood Possible Evidence D
Cytochrome P450 2D6 (Cyp2D6) Substrates

Valerian does not seem to have a clinically relevant effect on levels of drugs metabolized by CYP2D6.
Although some in vitro evidence suggests that valerian affects CYP2D6, clinical pharmacokinetic (PK) studies show that valerian is unlikely to affect the CYP2D6 enzyme. In one PK study, taking valerian 1000 mg (providing about 11 mg valerenic acid) nightly for 14 days did not affect the metabolism of dextromethorphan, a CYP2D6 substrate. In another PK study, taking valerian 125 mg three times daily for 28 days did not affect metabolism of debrisoquine, an accepted CYP2D6 probe-substrate.

Likelihood Unlikely Evidence B
Cytochrome P450 3A4 (Cyp3A4) Substrates

Valerian does not seem to have a clinically relevant effect on levels of drugs metabolized by CYP3A4.
Although some in vitro evidence suggests that valerian extract might inhibit or induce CYP3A4, clinical pharmacokinetic (PK) studies show that valerian does not have a clinically significant effect on the CYP3A4 enzyme. In one PK study, taking valerian 125 mg three times daily for 28 days did not affect metabolism of midazolam, an accepted CYP3A4 probe-substrate. In another PK study, taking valerian 1000 mg (providing about 11 mg valerenic acid) nightly for 14 days modestly increases levels of alprazolam, a CYP3A4 substrate, suggesting mild inhibition of CYP3A4. However, this mild inhibition is unlikely to be clinically relevant.

Likelihood Possible Evidence B

Hops Flower Extract4 drug types · 863 drugs

Cns Depressants

Theoretically, concomitant use of hops with sedative drugs might cause additive sedation.
Some animal research shows that hops has sedative effects.

Likelihood Possible Evidence D
Estrogens

Theoretically, concomitant use of large amounts of hops might interfere with hormone replacement therapy due to competition for estrogen receptors.
In vitro research suggests that certain hops constituents can competitively bind to estrogen receptors. However, most hops extracts contain very small amounts of these constituents.

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

Hops extract does not seem to affect the metabolism of CYP1A2 substrates.
In vitro research suggests that flavonoid constituents of hops inhibit CYP1A2 enzyme activity. However, a pharmacokinetic study in healthy postmenopausal patients shows that taking a standardized extract of spent hops containing prenylated phenols, as 59.5 mg twice daily for 2 weeks, does not affect levels of caffeine, a CYP1A2 probe substrate.

Likelihood Unlikely Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, hops extract might alter metabolism of CYP3A4 substrates; however, this effect may not be clinically significant.
Animal research suggests that specific constituents of hops, called lupulones, can induce hepatic CYP3A4 enzyme activity. However, a pharmacokinetic study in healthy postmenopausal patients with normal metabolism shows that taking a standardized extract of spent hops containing prenylated phenols, as 59.5 mg twice daily for 2 weeks, decreases the concentration of alprazolam, a CYP3A4 probe substrate, by 7.6%. This reduction is unlikely to be clinically relevant.

Likelihood Possible Evidence D

Passionflower3 drug types · 836 drugs

Cns Depressants

Concomitant use of passion flower with sedative drugs might cause additive effects and side effects.
Research in animals and humans shows that passion flower has sedative effects which can be additive when used with sedative medications like lorazepam.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, passion flower might decrease the effects of CYP3A4 substrates.
In vitro research suggests that passion flower can induce CYP3A4 enzymes, albeit to a much lower degree than rifampin, a known CYP3A4 inducer.

Likelihood Possible Evidence D
Organic Anion-Transporting Polypeptide Substrates (Oatp)

Theoretically, passion flower might reduce the bioavailability of OATP2B1 and OATP1A2 substrates.
In vitro research shows that the passion flower constituents apigenin and vitexin inhibit OATP2B1 and OATP1A2. This inhibition may be dose-dependent. One specific high-flavonoid passion flower extract (Valverde) seems to inhibit OATP2B1 and OATP1A2, while another extract with a lower flavonoid concentration (Arkocaps) shows less potent inhibition. OATPs are responsible for the uptake of drugs and other compounds into the body; however, the specific activities of OATP2B1 and OATP1A2 are not well characterized.

Likelihood Possible Evidence D

Lemon Balm Aerial Parts Extract2 drug types · 264 drugs

Cns Depressants

Theoretically, concomitant use of lemon balm might have additive effects with CNS depressant drugs.
Lemon balm seems to have CNS depressant activity in animals and in humans.

Likelihood Possible Evidence B
Thyroid Hormone

Theoretically, lemon balm might interfere with thyroid hormone replacement therapy.
In vitro, constituents of lemon balm extract bind to thyroid stimulating hormone (TSH), preventing TSH receptor-binding and leading to the inhibition of TSH-stimulated adenylate cyclase activity. In animals, lemon balm extract has been shown to decrease levels of circulating TSH and inhibit thyroid secretion.

CLM by Loomis Enzymes: Common Questions

Does CLM by Loomis Enzymes interact with any medications?
Yes. Based on its ingredients, CLM has a known interaction with 1,017 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
CLM contains 12 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 this help my digestion?
The enzyme blend is designed to aid digestion, but the evidence for most of these enzymes isn't established in our data. Valerian and Passionflower are included more for relaxation and sleep than digestive support.
Can I take this before bed?
Possibly—Valerian and Passionflower are traditionally used for sleep and are rated Possibly Effective for insomnia. However, all four herbal ingredients (Hops, Chamomile, Valerian, Passionflower, and Lemon Balm) can cause drowsiness, so avoid activities requiring alertness until you know how you respond. Don't combine with other sleep aids or alcohol without checking with your pharmacist first.
Is this safe if I'm pregnant or breastfeeding?
No—the safety data advises against the herbal ingredients during pregnancy, and breastfeeding safety is either unknown or not recommended without medical advice. Talk to your doctor or pharmacist about whether this product is right for you.
What are these enzymes supposed to do?
Amylase breaks down carbohydrates, Protease breaks down proteins, and Lipase breaks down fats. The others—Cellulase, Glucoamylase, Hemicellulase, and Alpha-Galactosidase—target other carbohydrates and fiber, and a proprietary blend provides additional enzyme activity.
Why is chamomile in an enzyme product?
Chamomile is included for its traditional calming effects and has some research support for relieving digestive discomfort, though the evidence isn't established in our data. It pairs with the other herbal extracts—Valerian, Passionflower, and Lemon Balm—to support relaxation alongside digestion.
Will this interact with my birth control or hormone therapy?
Possibly—Chamomile and Hops both have theoretical interactions with estrogens and contraceptives because of their plant-based estrogen-like activity. Check with your pharmacist with your specific medications before starting.
