HelloPharmacist Scorecard of Green Nutrients by NF NutriPlex Formulas

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
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 2 of its 7 active ingredients.
  • “Green Nutrients Food Complex Proprietary Blend” is a proprietary blend — the label gives one combined amount (640 mg) without saying how much of each component you get.

Green Nutrients contains seven active ingredients: alfalfa powder, parsley powder, dandelion powder, spinach powder, wheatgrass powder, broccoli powder, and Icelandic kelp powder, plus a proprietary blend labeled "Green Nutrients Food Complex." These are whole-food powders meant to provide nutrients from leafy and cruciferous vegetables and herbs. The product also contains three inactive ingredients—cellulose, croscarmellose sodium, and silica—which are fillers and binders.

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: Colorectal cancer — rated "Possibly Effective" (Broccoli) (Natural Medicines).

The evidence for most of these ingredients is not established in the data we hold. Alfalfa, parsley, dandelion, spinach, and wheatgrass all carry "Insufficient Reliable Evidence To Rate" for the conditions they're claimed to help—including diabetes, high cholesterol, joint pain, and liver health.

Broccoli is the one exception: it's rated Possibly Effective for reducing colorectal cancer risk. For all other uses listed, the evidence is insufficient or not on file.

The evidence, ingredient by ingredient Alfalfa Parsley Dandelion Spinach Broccoli Laminaria

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 6 of the 6 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 6 of 6.
  • General safety write-ups exist for 6 of 6.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Alfalfa is generally well tolerated but carries a "Possibly Unsafe" rating in pregnancy and lactation because it has estrogen-like activity. The most common side effects are digestive—abdominal discomfort, diarrhea, and gas.

Parsley is safe at food amounts but supplements and large doses aren't well studied; in very high doses it can cause serious effects like hemolytic anemia and kidney damage. Dandelion is generally well tolerated as a supplement but can cause allergy symptoms, diarrhea, or heartburn in some people.

Spinach is safe and nutritious as food, including in pregnancy and breastfeeding. Broccoli is safe as food; concentrated extracts are less studied.

Icelandic kelp is generally safe but can deliver very high and variable amounts of iodine, which may affect the thyroid—it's best avoided in pregnancy and breastfeeding unless a doctor directs otherwise. Kelp can also concentrate arsenic, which is a serious concern with long-term use.

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?
  • 6 of the 6 matched ingredients can interact with medications — Alfalfa, Spinach, Laminaria, Dandelion, Parsley, 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; heart-rhythm medications; lithium.
  • For scale: 865 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 your exact medications against this product if you take warfarin or other blood thinners—alfalfa carries a Major-severity interaction that can reduce how well they work. Also double-check if you're on diabetes drugs, thyroid medications, photosensitizing drugs, contraceptive pills, hormone therapy, immunosuppressants, potassium-sparing diuretics, ACE inhibitors, antithyroid drugs, amiodarone, digoxin, or any drug metabolized by CYP1A2 or CYP2A6.

All of these carry Moderate-severity interactions with one or more ingredients in this product.

The bottom line

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

If you're on warfarin or any other blood thinner, diabetes medication, thyroid medication, or potassium-regulating drugs, check with your pharmacist or doctor before taking this product. If you're pregnant or breastfeeding, talk with your doctor first—alfalfa and kelp carry specific safety concerns.

The evidence that these ingredients work for any particular health claim is very limited.

Each ingredient & the kinds of drugs it affects

For each ingredient in Green Nutrients 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.

Alfalfa, Powder6 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, Powder full monograph & interactions

Dandelion, Powder7 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, Powder full monograph & interactions

Parsley, Powder8 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, Powder full monograph & interactions

Broccoli, Powder2 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, Powder full monograph & interactions

Spinach, Powder2 drug types · 88 drugs

Antidiabetes Drugs

There are claims that spinach leaves have hypoglycemic effects. Evidence from clinical research suggests that consumption of a spinach-rich meal reduces post-meal blood glucose levels. Theoretically, spinach might have additive effects with antidiabetes drugs and increase the risk of hypoglycemia. Monitor blood glucose levels closely. Dose adjustments might be necessary. Some antidiabetes drugs include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, pioglitazone (Actos), rosiglitazone (Avandia), and others.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Spinach contains vitamin K, which can interfere with the activity of warfarin.
In human research, although eating spinach with one meal does not result in coagulation test results outside the therapeutic range, daily consumption for one week necessitates dose adjustment of warfarin. Individuals using anticoagulants should consume a consistent daily amount of spinach to maintain the effect of anticoagulant therapy.

Likelihood Possible Evidence D
Spinach, Powder full monograph & interactions

Icelandic Kelp Powder6 drug types · 69 drugs

Ace Inhibitors (Aceis)

Theoretically, laminaria might increase the risk of hyperkalemia when taken with ACEIs.
Laminaria contains potassium.

Likelihood Possible Evidence D
Amiodarone (Cordarone)

Theoretically, combining laminaria with amiodarone might cause excessively high iodine levels.
Amiodarone contains 37.3% iodine and can increase iodine levels. Concomitant use with laminaria supplements, some of which may contain as much as 1000 mcg iodine, might increase the risk of adverse effects from iodine, including altered thyroid function.

Likelihood Possible Evidence D
Antithyroid Drugs

Due to its iodine content, laminaria might alter the effects of antithyroid drugs.
Some laminaria supplements contain up to 1000 mcg of iodine. Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking laminaria could theoretically alter the effects of antithyroid drugs.

Likelihood Possible Evidence D
Digoxin (Lanoxin)

Theoretically, laminaria might increase the risk of hyperkalemia, which could increase the effects and adverse effects of digoxin.
Laminaria contains potassium.

Likelihood Possible Evidence D
Potassium-Sparing Diuretics

Theoretically, laminaria might increase the risk of hyperkalemia when taken with potassium-sparing diuretics.
Laminaria contains potassium.

Likelihood Possible Evidence D
Thyroid Hormone

Due to its iodine content, laminaria might alter the effects of thyroid hormone.
Some laminaria supplements contain up to 1000 mcg of iodine. Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking laminaria could theoretically alter the effects of thyroid hormone.

Green Nutrients by NF NutriPlex Formulas: Common Questions

Does Green Nutrients by NF NutriPlex Formulas interact with any medications?
Yes. Based on its ingredients, Green Nutrients has a known interaction with 865 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?
Green Nutrients contains 7 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.
Is it safe to take this if I'm on warfarin?
No—not without checking with your doctor first. Alfalfa in this product is high in vitamin K, which can reduce how well warfarin works to prevent clots. This is a Major-severity interaction, so you'll need close monitoring if you take both.
Can I take this while pregnant or breastfeeding?
Alfalfa in this product is rated Possibly Unsafe in pregnancy because it has estrogen-like activity. Kelp is best avoided while breastfeeding due to iodine, which can affect the infant's thyroid. Talk with your doctor or pharmacist before use.
Will this help with my diabetes or weight?
The evidence isn't established in our data. Most ingredients are rated Insufficient Reliable Evidence for diabetes, weight, or similar conditions. If you take diabetes medication, this product could theoretically lower your blood sugar further—monitor closely and check with your doctor first.
What are the most common side effects?
Digestive upset is the most common—gas, diarrhea, and stomach discomfort, especially from alfalfa and dandelion. These are usually mild, but if you have a sensitive gut, start low and increase slowly.
Does this contain iodine?
Yes, through the Icelandic kelp powder. Kelp can deliver variable and sometimes very high amounts of iodine, which may affect your thyroid. If you take thyroid medication or antithyroid drugs, check with your pharmacist before starting.
What is wheatgrass in this formula for?
We hold no interaction or effectiveness data for wheatgrass, so we can't tell you what role it plays in this product or whether it works for any condition.
