HelloPharmacist Scorecard of Green Foods Complex by ProCaps Laboratories

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

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 5 of its 5 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Green Foods Complex has 5 active ingredients — spirulina powder, barley grass powder, chlorella powder, wheat grass powder, and blue-green algae powder. Each is a whole-food plant source: spirulina and blue-green algae are nutrient-dense microalgae; barley grass and wheat grass are young cereal grasses; chlorella is a freshwater algae.

The product contains no other inactive ingredients listed. These ingredients work together as a concentrated green-food blend.

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

This product doesn't appear to be marketed for a specific use, so we graded its ingredients' overall clinical evidence instead.

Strong

Strong clinical evidence supports its ingredients for:

Why this rating?
  • The label markets general wellness (“General nutrition and wellness support”), not a specific health condition, so there is no single claim to grade against clinical-evidence data.
  • Since the label doesn't commit to one use, we graded the ingredients' overall clinical evidence instead.
  • On file: Coronary heart disease (CHD) — rated "Likely Effective" (Barley) (Natural Medicines).
  • On file: Hypercholesterolemia — rated "Likely Effective" (Barley) (Natural Medicines).
  • On file: Pregnancy-related iron deficiency — rated "Possibly Effective" (Chlorella) (Natural Medicines).
  • On file: Hypertension — rated "Possibly Effective" (Blue-green Algae) (Natural Medicines).

The evidence for this product's ingredients varies. Barley grass is likely effective for high cholesterol and heart disease prevention.

Spirulina is possibly effective for high blood pressure. The other ingredients — chlorella, wheat grass, and blue-green algae — have been studied for various uses (fatigue, liver health, anemia, brain tumors, depression), but the evidence isn't established enough to rate them, according to the data we hold.

The evidence, ingredient by ingredient Blue-green Algae Barley Chlorella Couch Grass

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 4 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 4 of 4.
  • General safety write-ups exist for 4 of 4.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Spirulina and blue-green algae are generally well tolerated, but quality and purity vary widely — some products can be contaminated with toxins or heavy metals. Common side effects include abdominal cramps, bloating, diarrhea, nausea, fatigue, and headache.

Rare but serious allergic reactions including anaphylaxis have been reported. Chlorella is also generally well tolerated short term but has limited long-term safety data and similar quality concerns.

Barley grass is safe as a food but contains gluten; concentrated supplements aren't well studied in pregnancy or breastfeeding. Wheat grass has limited human safety data.

There isn't enough pregnancy and breastfeeding safety information for spirulina, blue-green algae, chlorella, or wheat grass to know whether they're safe — talk with your doctor or pharmacist for personalized advice if you're pregnant or nursing.

Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 3 of the 4 matched ingredients can interact with medications — Barley, Chlorella, Blue-green Algae.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications.
  • For scale: 627 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 medications against this product if you take blood thinners or antiplatelet drugs (like warfarin, aspirin, or clopidogrel); diabetes medications; drugs that suppress your immune system; warfarin specifically (chlorella may reduce its effectiveness); or triclabendazole for parasitic infections. All of these carry Moderate-severity interactions with one or more ingredients here.

Formula

Wheat & barley grass Chlorella Spirulina Blue-green algae

Green Foods Complex is a gluten-free blend of the most popularly supplemented green foods, including wheat grass and barley grass, as well as spirulina, chlorella and blue-green algae. These diverse green foods owe their rich color to the chlorophyll they contain and together these five ingredients deliver a comprehensive and concentrated array of vitamins, minerals, enzymes and phytonutrients. More than just natural antioxidants, the ingredients in Green Foods Complex help supply your body with protective compounds and building blocks necessary for tissue growth and maintenance, as well as the ingredients required to support a healthy liver. Rather than choose a single "green food", our Green Foods Complex is packed with 100 milligrams each of barley grass, wheat grass, blue-green algae, chlorella and spirulina. Green Foods Complex is a complementary belnd of two gluten-free cereal grasses, along with the three most important microalgae to help support your cardiovascular, nervous, immune and detoxification systems. Each carefully chosen ingredient contributes the natural benefits of green foods that are so lacking in our modern diet. Although we all try to do our best and eat our "greens" every day, we don't always succeed and our Green Foods Complex makes it convenient and easy to receive the wonderful goodness of those vital, healthy "greens" every day.

Each ingredient & the kinds of drugs it affects

For each ingredient in Green Foods Complex 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.

Chlorella, Powder2 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, Powder full monograph & interactions

Spirulina, Powder3 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, Powder full monograph & interactions

Barley Grass, Powder1 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.

Green Foods Complex by ProCaps Laboratories: Common Questions

Does Green Foods Complex by ProCaps Laboratories interact with any medications?
Yes. Based on its ingredients, Green Foods Complex has a known interaction with 627 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Green Foods Complex contains 5 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 gluten?
Yes — barley grass, one of the five active ingredients, contains gluten. If you have celiac disease or gluten sensitivity, this product isn't right for you.
What are the most common side effects?
The algae and grass ingredients may cause abdominal cramps, bloating, diarrhea, nausea, fatigue, or headache, especially when you first start. These tend to be mild, and many people don't experience them at all.
Is this safe to take during pregnancy or breastfeeding?
There isn't enough safety data to know either way for most of these ingredients. Barley grass as a concentrated supplement also hasn't been well studied in pregnancy or while breastfeeding. Talk with your doctor or pharmacist before using this if you're pregnant or nursing — they can help you decide what's right for your situation.
Can this help with my high cholesterol?
Barley grass, one of the five ingredients, is likely effective for high cholesterol and heart disease. The other ingredients haven't been proven for this purpose in the evidence we have.
What's in the powder — are there fillers?
The product lists no inactive ingredients, so it's the five active powders only — no fillers or binders added.
Could this cause an allergic reaction?
Yes. Allergic reactions, including rare severe ones like anaphylaxis, have been reported with spirulina, blue-green algae, and chlorella. If you've had allergies to algae or grasses before, be cautious and talk to your pharmacist first.
