HelloPharmacist Scorecard of Psor-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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Oct 8, 2026

What’s inside

Partial disclosure
Ingredient Transparency · database check
Partial

Most active ingredients list an amount, but at least one is hidden in a blend or missing.

Why this rating?
  • The label discloses an exact amount for 2 of its 4 active ingredients.
  • “Proprietary Enzyme Blend” is a proprietary blend — the label gives one combined amount (84 mg) without saying how much of each component you get.

The active ingredients listed are lipase, cellulase, lecithin, a proprietary enzyme blend, and borage oil powder. Our data discusses lipase mainly in relation to digestive conditions such as inflammatory bowel disease and dyspepsia, lecithin in relation to Alzheimer disease, anxiety, and bipolar disorder, and borage in relation to eczema and ADHD.

The proprietary blend is listed as a group, and its component ingredients are the individual items named above. The product also lists inactive ingredients: microcrystalline cellulose, cellulose, water, and phytase.

These are non-active components that help form the capsule and product.

Does it work?

Couldn't assess
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
Not assessable

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: pH balancing system.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

For lipase, the evidence for inflammatory bowel disease, dyspepsia, and prematurity is rated Insufficient Reliable Evidence To Rate. For lecithin, Alzheimer disease is rated Likely Ineffective, while age-related cognitive decline, TPN-associated hepatic steatosis, anxiety, and bipolar disorder are rated Insufficient Reliable Evidence To Rate.

For borage, atopic dermatitis (eczema) is rated Possibly Ineffective, and ADHD, acute respiratory distress syndrome, and alcoholism are rated Insufficient Reliable Evidence To Rate. We hold no effectiveness rating for cellulase or the proprietary enzyme blend.

The evidence, ingredient by ingredient Lecithin Lipase Borage

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 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Lipase is generally well tolerated in supplement form, but people with serious digestive conditions should use it only under medical guidance. Its pregnancy entry has no rating on file, and the safety notes say there is little safety data on supplemental lipase in pregnancy, so use it only if your doctor advises it.

Breastfeeding has not been well studied, so check with your healthcare provider first. Lecithin is rated Likely Safe in pregnancy.

Its breastfeeding notes say to check with your healthcare provider first, and it can cause allergic skin reactions in people with egg or soy allergies. Borage is rated Likely Unsafe in pregnancy, and the safety data advises against it because of possible liver-toxic alkaloids.

We hold no pregnancy or breastfeeding entry for cellulase or the enzyme blend.

Side effects, ingredient by ingredient Lecithin Lipase Borage

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 3 matched ingredients can interact with medications — Borage.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 227 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.

Double-check with your doctor or pharmacist before taking this product if you use anticoagulant or antiplatelet drugs, phenothiazines, or CYP3A4 inducers, all rated Moderate in our data. Borage is the ingredient responsible for all three.

We could not check cellulase or the proprietary enzyme blend, so their medication interactions are not covered here.

Check your own medication Run your meds through the checker above

The bottom line

Scorecard at a glancePartially disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product may be of interest to people looking into lipase, lecithin, or borage for the uses covered in our data, though the evidence for most of those uses is not established. People with serious digestive conditions, people who are pregnant or breastfeeding, and anyone taking blood thinners, seizure-related or antipsychotic medications, or CYP3A4-affected drugs should be especially careful.

Talk it over with your own doctor or pharmacist before you start.

Each ingredient & the kinds of drugs it affects

For each ingredient in Psor-Rbs 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.

Borage Oil, Powder3 drug types · 226 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, borage seed oil may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In healthy individuals, borage seed oil supplementation does not seem to affect platelet aggregation. However, gamma-linolenic acid, a constituent of borage seed oil, seems to decrease platelet aggregation by 45% and increase the risk of bleeding by 40% in animal and clinical research.

Likelihood Possible Evidence B
Cytochrome P450 3A4 (Cyp3A4) Inducers

Theoretically, taking borage with drugs that induce CYP3A4 might increase levels of pyrrolizidine alkaloid (PA) toxic metabolites.
Although borage seed oil contains little to no PAs, some borage plant parts, such as the leaf, flower, and seed, can contain hepatotoxic PAs. Hepatotoxic PAs are substrates of CYP3A4, which converts these chemicals into toxic metabolites. Tell patients to avoid borage preparations that are not certified and labeled as hepatotoxic PA-free.

Likelihood Possible Evidence D
Phenothiazines

Theoretically, taking borage sed oil with phenothiazines might increase the risk of seizures.
Borage seed oil contains gamma-linolenic acid (GLA). There is concern that taking supplements containing GLA might cause seizures, or lower the seizure threshold, when taken with phenothiazines. This is based on limited data from two reports published in the 1980s. In one report, three patients with schizophrenia who had received phenothiazines developed EEG changes suggestive of temporal lobe epilepsy after starting treatment with evening primrose, another source of GLA. However, none experienced an actual seizure. In the other report, two patients with schizophrenia who were stabilized on phenothiazines developed seizures when evening primrose 4 grams daily was added. One of these patients had a prior history of seizures. It is unclear whether evening primrose had any additive epileptogenic effects with the phenothiazines, but there is no evidence that taking GLA-containing supplements alone can cause seizures.

Lecithin is rated Likely Ineffective for Alzheimer disease in our data. Its ratings for anxiety and bipolar disorder are Insufficient Reliable Evidence To Rate.
