HelloPharmacist Scorecard of Spirulina & Astaxanthin Blue Complex by California Gold Nutrition

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

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 4 of its 7 active ingredients.
  • “Spirulina Astaxanthin Complex Blend” is a proprietary blend — the label gives one combined amount (1 Gram(s)) without saying how much of each component you get.

Spirulina & Astaxanthin Blue Complex contains 7 active ingredients: chlorophyll, astaxanthin (listed twice in the formulation), spirulina (blue-green algae), phycocyanin (twice), and total carotenoids. Chlorophyll is the green pigment in plants; astaxanthin is a reddish carotenoid antioxidant from algae; spirulina is a nutrient-dense blue-green algae; and phycocyanin is a protein-pigment complex from spirulina that gives it its blue color.

The product also contains inactive ingredients — hydroxypropyl methylcellulose (a thickener and capsule binder), natural vanilla flavor, and silicon dioxide (an anti-caking agent).

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: Hypertension — rated "Possibly Effective" (Blue-green Algae) (Natural Medicines).

The evidence backing these ingredients is limited. Spirulina is rated possibly effective for high blood pressure — human research shows promise, though the effect may be modest.

Chlorophyll, astaxanthin, and phycocyanin have insufficient reliable evidence for the conditions studied so far — age-related macular degeneration, cognitive decline, skin aging, athletic performance, wound healing, and others all lack enough solid data in our files to rate them. That doesn't mean they don't work; it means the evidence we have isn't strong enough yet to say.

The evidence, ingredient by ingredient Blue-green Algae Chlorophyll Astaxanthin

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.

Chlorophyll is generally well tolerated in short-term use, but long-term safety data are sparse. The most common side effect is photosensitization — increased sensitivity to sunlight that can cause blisters (pseudoporphyria) in rare cases, especially with sun exposure.

Astaxanthin appears well tolerated in studies; the most common side effects are abdominal pain, diarrhea, and red-colored stools at higher doses. Spirulina is also generally well tolerated, though some users report abdominal cramps, bloating, diarrhea, dizziness, fatigue, flatulence, headache, nausea, and vomiting.

Rarely, allergic reactions including anaphylaxis have occurred. Quality and contamination vary among spirulina products — some batches have contained toxins or heavy metals.

Neither chlorophyll nor astaxanthin should be used during pregnancy or while breastfeeding — there isn't enough safety data, and the manufacturers advise against it. Spirulina also carries a contamination risk and insufficient safety data in pregnancy and lactation — avoid unless your doctor advises otherwise.

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?
  • 3 of the 3 matched ingredients can interact with medications — Chlorophyll, Blue-green Algae, Astaxanthin.
  • 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: 1,146 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 this, double-check with your doctor or pharmacist if you're on methotrexate (a moderate interaction risk with chlorophyll), photosensitizing drugs like certain antibiotics or anti-inflammatory medications, blood thinners or antiplatelet drugs, immune-suppressing medications, or diabetes medications. Astaxanthin may also affect how your liver processes medications broken down by CYP3A4 and CYP2B6 enzymes — a large group including heart and blood pressure drugs.

No interactions are documented for phycocyanin and total carotenoids in our data.

The bottom line

Scorecard at a glancePartially disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

This product may be worth considering if you're interested in antioxidants and your doctor agrees it's appropriate for you. However, if you take any prescription medications — especially blood thinners, methotrexate, immune suppressors, diabetes drugs, or drugs that make you sun-sensitive — you need to check with your own doctor or pharmacist before starting it.

Pregnant or breastfeeding? Skip it unless your healthcare provider gives you the green light.

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.

Spirulina & Astaxanthin Blue Complex by California Gold Nutrition: Common Questions

Does Spirulina & Astaxanthin Blue Complex by California Gold Nutrition interact with any medications?
Yes. Based on its ingredients, Spirulina & Astaxanthin Blue Complex has a known interaction with 1,145 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Spirulina & Astaxanthin Blue Complex contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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.
Can I take this if I'm pregnant or breastfeeding?
No — chlorophyll and astaxanthin should be avoided during pregnancy and breastfeeding because there isn't enough safety data. Spirulina also carries a contamination risk and unknown safety in pregnancy and lactation. Talk with your doctor or pharmacist before taking this if you're pregnant, planning to become pregnant, or breastfeeding.
What are the most common side effects?
Chlorophyll can cause photosensitization (sun sensitivity). Astaxanthin may cause abdominal pain, diarrhea, or red-colored stools. Spirulina may cause abdominal cramps, bloating, diarrhea, dizziness, fatigue, nausea, or headache. Most users tolerate it well, but effects vary.
Does this product actually work?
Spirulina is rated possibly effective for high blood pressure based on human research. Chlorophyll and astaxanthin lack enough reliable evidence for the uses we've looked at — age-related macular degeneration, cognitive decline, skin aging, and others — so we can't say they're effective based on current data.
Is there a risk of contamination in spirulina products?
Yes — the quality and purity of spirulina products vary, and some batches have contained toxins or heavy metals. This is why safety data are limited and pregnancy/breastfeeding is advised against.
What is phycocyanin and why is it in this product?
Phycocyanin is a blue protein-pigment complex naturally present in spirulina that gives it its blue color. We have no interaction data on file for it, so we can't assess its safety with medications.
Should I stop taking my blood thinner to use this product?
No — never stop a blood thinner without your doctor's approval. Spirulina may theoretically increase bleeding risk if used with blood thinners or antiplatelet drugs. Talk with your doctor or pharmacist before adding this product if you're on these medications.
