HelloPharmacist Scorecard of Bio-Greens by MBi Nutraceuticals

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 1 of its 10 active ingredients.

Bio-Greens contains 10 ingredients. The active ones are dandelion leaf and root, kale, broccoli, alfalfa, parsley, spirulina algae (a blue-green algae), wheat grass, barley grass, and chlorella algae — plus a fiber ingredient we could not evaluate.

These are all plant-based components often used in greens supplements for their nutrient density. The product also contains three inactive ingredients: magnesium stearate, silica, and vegetable cellulose, which serve as binders and capsule material.

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
Strong

Clinical evidence supports at least one of this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: normalize body functions with natural vitamins and minerals.
  • We looked for evidence on: Malnutrition, Fatigue, Constipation, Dyspepsia, Flatulence, Diarrhea — and 4 related terms.
  • The strongest evidence on file: Barley is rated "Likely Effective" for Hypercholesterolemia (Natural Medicines).
  • Also on file: Alfalfa is rated "Insufficient Reliable Evidence To Rate" for Dyspepsia, Hypercholesterolemia.
  • Also on file: Dandelion is rated "Insufficient Reliable Evidence To Rate" for Constipation, Dyspepsia, Flatulence.

The evidence for most of these ingredients is limited. Barley grass is listed as likely effective for high cholesterol and heart disease risk.

Broccoli is possibly effective for colorectal cancer prevention. Spirulina algae is possibly effective for high blood pressure.

The rest — including dandelion, kale, alfalfa, parsley, wheat grass, and chlorella — have insufficient reliable evidence to rate them for their claimed uses in this product. In short, we don't have solid proof that this combination works for any specific condition.

The evidence, ingredient by ingredient Dandelion Kale Broccoli Alfalfa Parsley Blue-green Algae Couch Grass Barley

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 9 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 9 of 9.
  • General safety write-ups exist for 9 of 9.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Most of these ingredients are generally well tolerated in food amounts, but concentrated supplements raise more concern. Dandelion can cause diarrhea, heartburn, and stomach discomfort, and rarely anaphylaxis in sensitive people; it's also not well studied at supplement doses.

Alfalfa is best avoided at supplement strength during pregnancy because of its estrogen-like compounds. Parsley in large doses may cause hallucinations, anemia, or kidney damage, and shouldn't be used during pregnancy in medicinal amounts.

Barley contains gluten and can trigger allergic reactions. Chlorella may cause photosensitivity (sun sensitivity) and rare anaphylaxis.

Spirulina quality varies widely and can be contaminated with toxins or heavy metals. Kale as food is generally considered safe during pregnancy and breastfeeding, but concentrated forms are less studied.

Wheat grass has insufficient safety data for pregnancy and breastfeeding.

Meds to double-check

Major interaction found
Known Interaction Concern · database check
Major identified

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

Why this rating?
  • 7 of the 9 matched ingredients can interact with medications — Alfalfa, Dandelion, Parsley, Barley, Chlorella, among others.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications; lithium.
  • For scale: 840 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.

Check with your pharmacist before taking Bio-Greens if you use warfarin or other blood thinners (anticoagulants or antiplatelet drugs) — alfalfa, dandelion, parsley, chlorella, and spirulina may increase bleeding risk or reduce warfarin's effectiveness. Diabetes medications (antidiabetes drugs) — dandelion, alfalfa, parsley, and spirulina may lower blood sugar too much.

Water pills or diuretics — dandelion and parsley may interact. Birth control pills or hormone therapy — alfalfa may reduce effectiveness.

Immunosuppressants — alfalfa and spirulina may interfere. Liver-metabolized drugs (CYP1A2 and CYP2A6 substrates) — dandelion, broccoli, and parsley may change drug levels.

Fluoroquinolone antibiotics — dandelion may reduce absorption. Use the medication checker below for your specific drugs.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with clinical evidence supporting its stated purpose. Major medication interactions have been identified, and safety information is well characterized.

Bio-Greens is a multi-ingredient greens supplement with limited proven effectiveness for any specific condition. If you take warfarin, diabetes drugs, blood thinners, birth control, hormone therapy, immunosuppressants, or certain antibiotics, you need to check this product with your pharmacist first — the interactions are real and could affect how your medications work.

Even if you're on other prescriptions, run them through the checker on this page before you start. Talk with your pharmacist about whether this product makes sense for you.

Each ingredient & the kinds of drugs it affects

For each ingredient in Bio-Greens 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.

Alfalfa6 drug types · 583 drugs

Warfarin (Coumadin)

Theoretically, alfalfa might reduce the anticoagulant activity of warfarin.
Alfalfa contains a large amount of vitamin K. This could theoretically interfere with the activity of warfarin.

Likelihood Probable Evidence D
Antidiabetes Drugs

Theoretically, alfalfa might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal research suggests that alfalfa decreases blood sugar in diabetic mice. Also, in one case report, a diabetic patient experienced hypoglycemia after consuming alfalfa extract. Monitor blood glucose levels closely. Dose adjustments might be necessary.

Likelihood Possible Evidence D
Contraceptive Drugs

Theoretically, alfalfa might interfere with the activity of contraceptive drugs.
Alfalfa contains coumestrol, a phytoestrogen, and isoflavonoids, which have estrogenic effects.

Likelihood Possible Evidence D
Estrogens

Theoretically, alfalfa might interfere with hormone therapy.
Alfalfa contains coumestrol, a phytoestrogen, and isoflavonoids, which have estrogenic effects.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, alfalfa might decrease the efficacy of immunosuppressive therapy.
In vitro research and human case reports suggest that alfalfa may have immunostimulant effects.

Likelihood Possible Evidence D
Photosensitizing Drugs

Theoretically, concomitant use of alfalfa with photosensitizing drugs might have additive effects.
Animal research suggests that excessive doses of alfalfa may increase photosensitivity, possibly due to its chlorophyll content. It is unclear if this effect would be clinically relevant in humans.

Likelihood Possible Evidence D
Alfalfa full monograph & interactions

Dandelion7 drug types · 457 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, taking dandelion root along with anticoagulant or antiplatelet drugs might increase the risk of bruising and bleeding.
In vitro research suggests that dandelion root inhibits platelet aggregation.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, dandelion might increase the risk for hypoglycemia when used with antidiabetes drugs.
Laboratory research suggests that dandelion extract may have moderate alpha-glucosidase inhibitor activity and might also increase insulin secretion. Also, in a case report, a 58-year-old woman with type 2 diabetes who was being treated with insulin developed hypoglycemia 2 weeks after beginning to eat salads containing dandelion.

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

Theoretically, dandelion might increase levels of drugs metabolized by CYP1A2.
Laboratory research suggests that dandelion might inhibit CYP1A2. So far, this interaction has not been reported in humans. However, until more is known, watch for an increase in the levels of drugs metabolized by CYP1A2 in patients taking dandelion.

Likelihood Possible Evidence D
Glucuronidated Drugs

Theoretically, dandelion might increase the clearance of drugs that are UDP-glucuronosyltransferase substrates.
There is some preliminary evidence that dandelion might induce UDP-glucuronosyltransferase, a phase II enzyme.

Likelihood Possible Evidence D
Lithium

Theoretically, through diuretic effects, dandelion might reduce excretion and increase levels of lithium.
Animal research suggests that dandelion has diuretic properties. As diuretics can increase serum lithium levels, the dose of lithium might need to be decreased when taken with dandelion.

Likelihood Probable Evidence D
Potassium-Sparing Diuretics

Theoretically, dandelion might increase the risk of hyperkalemia when taken with potassium-sparing diuretics.
Dandelion contains significant amounts of potassium.

Likelihood Possible Evidence D
Quinolone Antibiotics

Theoretically, dandelion might lower fluoroquinolone levels.
Animal research shows that dandelion reduces absorption of ciprofloxacin and can lower levels by 73%. However, this effect has not been reported in humans.

Likelihood Possible Evidence D
Dandelion full monograph & interactions

Parsley8 drug types · 443 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, parsley might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
Animal research suggests that parsley has antiplatelet effects.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, parsley might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal research suggests that parsley might decrease blood glucose. Monitor blood glucose levels closely. Dose adjustments might be necessary.

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

Theoretically, parsley might increase serum levels of CYP1A2 substrates.
Laboratory research suggests that parsley can inhibit CYP1A2.

Likelihood Possible Evidence D
Diuretic Drugs

Theoretically, parsley might enhance or interfere with the effects of diuretic drugs.
Animal research suggests that parsley seed extract increases urine elimination. Parsley leaf and root might also interfere with diuretic therapy due their purported aquaretic effects.

Likelihood Possible Evidence D
Pentobarbital (Nembutal)

Theoretically, parsley might increase the duration of pentobarbital effects.
Animal research suggests that parsley juice prolongs the action of pentobarbital, perhaps by decreasing cytochrome P450 levels. It is not known if this occurs in humans or if this applies to other barbiturates or sedatives.

Likelihood Possible Evidence D
Sirolimus (Rapamune)

Theoretically, large quantities of parsley might increase sirolimus levels.
In one case report, an adult female with a history of kidney transplant presented with elevated blood sirolimus levels, approximately 4-7 times greater than previous measures, after daily consumption of a juice containing approximately 30 grams of parsley for 7 days. Sirolimus levels returned to normal a week after the parsley juice was discontinued.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, large amounts of parsley leaf and root might decrease the effects of warfarin.
Parlsey contains vitamin K.

Likelihood Possible Evidence D
Aspirin

Theoretically, aspirin might increase the severity of allergic reactions to parsley.
In one case, severe urticaria and swelling were reported after taking aspirin with parsley in an individual with a known mild parsley allergy.

Likelihood Unlikely Evidence D
Parsley full monograph & interactions

Chlorella Algae2 drug types · 337 drugs

Photosensitizing Drugs

Theoretically, chlorella might have additive effects with photosensitizing drugs.
Chlorella has been reported to cause photosensitization. In five case reports, patients who had ingested chlorella exhibited swelling followed by erythematopurpuric lesions on sun-exposed areas of the body. Theoretically, concomitant use with photosensitizing drugs may exacerbate effects.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, chlorella might reduce the clinical effects of warfarin.
Chlorella contains significant amounts of vitamin K. There is at least one case report of warfarin therapy becoming sub-therapeutic after initiation of chlorella supplements.

Likelihood Possible Evidence D
Chlorella Algae full monograph & interactions

Spirulina Algae3 drug types · 327 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, spirulina blue-green algae might increase the risk of bleeding if used with other anticoagulant or antiplatelet drugs. However, this is unlikely.
Spirulina blue-green algae have shown antiplatelet and anticoagulant effects in vitro. However, one preliminary study in 24 patients receiving spirulina blue-green algae 2.3 grams daily for 2 weeks showed no effect on platelet activation or measures of clotting time.

Likelihood Unlikely Evidence D
Antidiabetes Drugs

Theoretically, taking blue-green algae with antidiabetes drugs might increase the risk of hypoglycemia.
Human research shows that spirulina blue-green algae can have hypoglycemic effects in patients with diabetes, at least some of whom were using antidiabetes drugs. However, blue-green algae does not seem to improve glycated hemoglobin (HbA1c) levels in patients with diabetes. A meta-analysis of animal studies also suggests that spirulina blue-green algae have hypoglycemic effects.

Likelihood Possible Evidence B
Immunosuppressants

Theoretically, concurrent use of blue-green algae might interfere with immunosuppressive therapy.
Blue-green algae have been shown to stimulate the immune system.

Likelihood Possible Evidence D
Spirulina Algae full monograph & interactions

Broccoli2 drug types · 187 drugs

Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, broccoli might reduce the levels and effects of drugs metabolized by CYP1A2.
Pharmacokinetic research in humans shows that eating 500 grams of fresh broccoli daily for 6-12 days can increase CYP1A2 activity by 10% to 200%. Induction of CYP1A2 activity by broccoli is attributed to its glucosinolate constituents.

Likelihood Possible Evidence B
Cytochrome P450 2A6 (Cyp2A6) Substrates

Theoretically, broccoli might reduce the levels and effects of drugs metabolized by CYP2A6.
Pharmacokinetic research in humans shows that eating 500 grams of broccoli daily for 6 days increases CYP2A6 activity by 135% to 550%. Induction of CYP2A6 activity is attributed to its glucosinolate constituents.

Likelihood Possible Evidence B
Broccoli full monograph & interactions

Barley Grass1 drug type · 1 drug

Triclabendazole (Egaten)

Theoretically, barley might decrease the clinical effects of triclabendazole.
Animal research suggests that a diet supplemented with barley can reduce the bioavailability of triclabendazole when taken concomitantly. This effect has not been shown in humans.

Bio-Greens by MBi Nutraceuticals: Common Questions

Does Bio-Greens by MBi Nutraceuticals interact with any medications?
Yes. Based on its ingredients, Bio-Greens has a known interaction with 840 medications, including 2 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Bio-Greens contains 11 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.
Does this product contain any gluten?
Yes. Barley grass, one of the active ingredients, contains gluten. If you have celiac disease or gluten sensitivity, this product is not appropriate for you.
Can I take this while pregnant?
No — at least not without checking with your doctor first. Alfalfa is marked as possibly unsafe during pregnancy because of its estrogen-like compounds, and parsley shouldn't be used in medicinal amounts while pregnant either. Kale and barley as foods are okay, but this is a concentrated supplement, not just food.
Is this safe while breastfeeding?
The safety data are very limited. Kale and barley as foods are considered fine, but concentrated supplements of most of these ingredients — especially parsley, alfalfa, chlorella, and wheat grass — lack enough safety information. Talk with your doctor or pharmacist before taking it while nursing.
Can this product cause side effects?
Yes. The most common ones are stomach upset, diarrhea, bloating, and gas — especially from dandelion, alfalfa, broccoli, and spirulina. Chlorella can cause nausea and photosensitivity (sun sensitivity on your skin). Rare but serious reactions like anaphylaxis have been reported with dandelion, parsley, barley, and chlorella in sensitive people.
Does this help with high cholesterol or heart disease?
Barley grass in this product is listed as likely effective for high cholesterol and heart disease. The other ingredients don't have established proof for these conditions. One ingredient alone doesn't guarantee the whole product will work, so talk with your doctor about whether this fits your needs.
What if I'm allergic to ragweed or daisies?
Be cautious. Dandelion is in the same plant family as ragweed, daisies, and chrysanthemums. If you have allergies to those plants, you may react to dandelion in this product. Check with your pharmacist before use.
