HelloPharmacist Scorecard of Rbs 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.
What’s inside
Low disclosure
Rbs contains 12 ingredients, most of them digestive enzymes. The active enzymes include Protease (a protein-digesting enzyme), Lipase (a fat-digesting enzyme), and several others: Amylase, Cellulase, Glucoamylase, Hemicellulase, and Alpha-Galactosidase.
The product also includes Artichoke Leaf Extract, Chamomile, Lecithin, and Wheat Germ. The inactive ingredients are Phytase, Cellulose, and Water.
Does it work?
Couldn't assess
Effectiveness data is established for only a few ingredients. Artichoke Leaf Extract is possibly effective for high cholesterol (hyperlipidemia) and indigestion (dyspepsia).
Lecithin is likely ineffective for Alzheimer disease, but evidence is insufficient to rate it for age-related cognitive decline, liver fat buildup, anxiety, or bipolar disorder. Lipase shows insufficient evidence for inflammatory bowel disease, indigestion, or prematurity.
We hold no effectiveness ratings for the other enzymes in this product.
How safe is it?
Well-documented data
Protease is generally well tolerated for most adults, though it may cause digestive upset or allergic reactions in some people. Lipase is also generally well tolerated in supplement form, but people with serious digestive conditions should use it only under medical guidance.
Lecithin is considered generally safe in food and supplement amounts and is likely safe in pregnancy; check with your doctor before using supplements, and check with your healthcare provider if breastfeeding. Artichoke Leaf Extract is generally well tolerated but may cause abdominal pain, diarrhea, bloating, hunger, or nausea.
People with an allergy to ragweed, chrysanthemums, daisies, or other plants in the daisy family may react to artichoke. Anaphylaxis to artichoke, though rare, has been reported.
Protease and Artichoke are best avoided during pregnancy and breastfeeding due to insufficient safety data.
Meds to double-check
Moderate interaction found
Blood pressure medications (antihypertensive drugs) — artichoke may lower blood pressure further. Diabetes medications (antidiabetes drugs) — artichoke may increase the risk of low blood sugar.
Ask your pharmacist whether you take any drugs processed by your liver via CYP2C19 or CYP2B6 pathways, as artichoke may theoretically raise their levels.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
Rbs is an enzyme supplement that may help with digestion, though the evidence for most individual enzymes is limited. If you take blood pressure or diabetes medications, check your specific drugs with the tool on this page — artichoke can interact with both.
Talk to your pharmacist or doctor before starting, especially if you're pregnant, breastfeeding, or have a history of allergies to plants in the daisy family.

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.
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.
Tamoxifen (Nolvadex)
Theoretically, large amounts of German chamomile might interfere with the activity of tamoxifen.
In vitro, German chamomile has demonstrated antiestrogenic activity.
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.
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.
Kelp
Amiodarone (Cordarone)
Theoretically, combining Fucus vesiculosus with amiodarone might cause excessively high iodine levels.
Fucus vesiculosus contains high concentrations of iodine. Amiodarone contains 37.3% iodine and can increase iodine levels. Concomitant use might increase the risk of having excessive iodine levels and adversely affecting thyroid function. Monitor thyroid function.
Antithyroid Drugs
Due to its iodine content, Fucus vesiculosus might alter the effects of antithyroid drugs.
Fucus vesiculosus contains high concentrations of iodine. Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking Fucus vesiculosus while using antithyroid drugs could alter the effects of the antithyroid drugs.
Lithium
Concomitant use of Fucus vesiculosus and lithium has resulted in hyperthyroidism.
There is a case of hyperthyroidism occurring in a patient taking Fucus vesiculosus and lithium. Monitor thyroid hormones closely in patients taking lithium and Fucus vesiculosus concomitantly.
Thyroid Hormone
Due to its iodine content, Fucus vesiculosus might alter the effects of thyroid hormone.
Fucus vesiculosus contains high concentrations of iodine. Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking Fucus vesiculosus while using thyroid hormone could alter the effects of thyroid hormone.
Anticoagulant/Antiplatelet Drugs
Theoretically, taking Fucus vesiculosus with antiplatelet or anticoagulant drugs might increase the risk of bruising and bleeding.
In vitro evidence suggests that a constituent of Fucus vesiculosus, known as fucoidan, has anticoagulant effects. However, in clinical research, fucoidan does not seem to have significant anticoagulant activity when taken orally, possibly due to poor absorption.
Cytochrome P450 2C8 (Cyp2C8) Substrates
Theoretically, concomitant use of Fucus vesiculosus with CYP2C8 substrates might increase the risk for adverse effects.
In vitro research shows that fucoidan, a constituent of Fucus vesiculosus, inhibits CYP2C8. This interaction has not been reported in humans.
Cytochrome P450 2C9 (Cyp2C9) Substrates
Theoretically, concomitant use of Fucus vesiculosus with CYP2C9 substrates might increase the risk for adverse effects.
In vitro research shows that fucoidan, a constituent of Fucus vesiculosus, inhibits CYP2C9. This interaction has not been reported in humans.
Cytochrome P450 2D6 (Cyp2D6) Substrates
Theoretically, concomitant use of Fucus vesiculosus with CYP2D6 substrates might alter the effects of these substrates.
In vitro research shows that fucoidan, a constituent of Fucus vesiculosus, both inhibits and induces CYP2D6. This interaction has not been reported in humans.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, concomitant use of Fucus vesiculosus with CYP3A4 substrates might increase the risk for adverse effects.
In vitro research shows that fucoidan, a constituent of Fucus vesiculosus, inhibits CYP3A4. This interaction has not been reported in humans.
Artichoke Leaf Extract
Antidiabetes Drugs
Theoretically, artichoke leaf extract may increase the risk of hypoglycemia when taken with antidiabetes drugs.
A meta-analysis of small clinical studies shows that taking artichoke leaf extract for 8-12 weeks can modestly reduce fasting plasma glucose when compared with placebo.
Antihypertensive Drugs
Theoretically, artichoke leaf extract may increase the risk of hypotension when taken with antihypertensive drugs.
A meta-analysis of small clinical studies in patients with hypertension shows that taking artichoke can reduce systolic blood pressure by around 3 mmHg and diastolic blood pressure by around 2 mmHg when compared with placebo.
Cytochrome P450 2B6 (Cyp2B6) Substrates
Theoretically, artichoke might increase serum levels of drugs metabolized by CYP2B6.
In vitro research shows that artichoke leaf extract inhibits CYP2B6 activity. However, this interaction has not been reported in humans.
Cytochrome P450 2C19 (Cyp2C19) Substrates
Theoretically, artichoke might increase serum levels of drugs metabolized by CYP2C19.
In vitro research shows that artichoke leaf extract inhibits CYP2C19 activity. However, this interaction has not been reported in humans.
Wheat Germ
Antidiabetes Drugs
Theoretically, taking wheatgrass with antidiabetes drugs might lower blood glucose levels and increase the risk of hypoglycemia.
Animal research shows that taking wheatgrass stimulates the release of insulin from beta-cells and lowers blood glucose.
