HelloPharmacist Scorecard of Klamath Shores Blue Green Algae by American Health

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

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 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains a single active ingredient: Klamath Lake blue-green algae, a freshwater algae sourced from Klamath Lake. The capsule also holds inactive ingredients (gelatin, vegetable magnesium stearate, and silica) that serve as binders and flow agents.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Blue-green Algae's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: Natural plant-based nutrition and wellness support.
  • We looked for evidence on: Athletic performance, Cognitive Impairment, Dyslipidemia, Memory, Mental alertness, Metabolic syndrome — and 4 related terms.
  • The closest evidence on file: Blue-green Algae is rated "Insufficient Reliable Evidence To Rate" for Athletic performance (Natural Medicines).
  • Also on file: Blue-green Algae is rated "Insufficient Reliable Evidence To Rate" for Cognitive Impairment, Dyslipidemia, Memory, Mental alertness, and more.

The evidence for this product is mixed. It's rated possibly effective for high blood pressure (hypertension).

However, for acne, hay fever (allergic rhinitis), iron deficiency anemia, and arsenic poisoning, we don't have enough reliable evidence to say whether it works. The data we hold doesn't establish effectiveness for those uses.

The evidence, ingredient by ingredient Blue-green Algae

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 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Blue-green algae is generally well tolerated when taken by mouth. The most common side effects reported are stomach cramps, bloating, diarrhea, dizziness, fatigue, gas, headache, nausea, and vomiting.

Allergic reactions, including rashes, itching, and in rare cases severe reactions like anaphylaxis, have been reported. There's also a caution about quality: some blue-green algae products can be contaminated with toxins or heavy metals, so source and purity matter.

Pregnancy and lactation safety data isn't on file for this ingredient, so talk with your doctor or pharmacist if you're pregnant, planning to become pregnant, or breastfeeding.

Meds to double-check

Moderate interaction found

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 1 matched ingredient can interact with medications — 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: 327 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.

Before you take Klamath Shores Blue Green Algae, check with your pharmacist if you're on blood thinners or antiplatelet drugs (like warfarin or aspirin)—there's a Moderate risk of increased bleeding. Also double-check if you take immunosuppressants or diabetes drugs; both carry Moderate interaction risks.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

This product may be worth considering if you're interested in managing blood pressure and can tolerate the side effects. If you take blood thinners, diabetes drugs, or immunosuppressants, talk with your pharmacist first—we need to make sure it won't interfere.

Because contamination can be an issue with algae products, quality and source matter. Your pharmacist can help you weigh the benefits and risks for your situation.

Klamath Lake Blue Green 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.
