Spirulina.Guru

Membership

Independent spirulina research, member-supported

Mechanistic depth, honest brand reviews, and clinical protocols — funded by readers, not by the industry. Join from $7/month.

What members get

120+ mechanistic deep-dives

Every signaling pathway, transcription factor, and clinical mechanism — referenced from peer-reviewed literature, written in plain English. The depth you can't find on any other supplement site.

Detailed brand reviews

Beyond the public brand directory: individual brand deep-dives with Certificate of Analysis interpretation, supply chain notes, and our honest verdict on whether it's worth your money.

Specific clinical protocols

Condition-specific dosing guides built from intervention trial data: cardiovascular risk, metabolic syndrome, perimenopause, athletic recovery, post-viral fatigue.

Quarterly evidence updates

We track new spirulina research in real time and summarize what changed your assumptions — and what didn't. Members get the digest first.

Member-only Q&A

Submit your specific situation (anonymized) and get a researched answer. No medical advice — informational only, evidence-grounded.

Ad-free, sponsor-free, MLM-free

Membership funds independence. We never accept brand sponsorships. We never recommend products on commission unless we'd already buy them ourselves.

Frequently asked

Why a paywall on a health site?

Because the alternative is sponsorships, affiliate-driven 'top 10' lists, or MLM partnerships — and that's how 99% of supplement content already works. Membership is what lets us stay honest. Free tier remains substantial: ~300+ articles covering recipes, basic science, safety, and brand directory.

What's in the free tier?

All editorial pieces, all recipes, all community content, the brand directory, safety guidance, and ~30 foundational science articles. You can navigate, search, and read those forever without an account.

Can I cancel?

Yes, anytime. Monthly auto-renews unless cancelled. Annual gives a full refund within the first 14 days. Founder tier is non-refundable after 14 days since it's a one-time payment.

Do you give medical advice?

No. Everything on this site is informational and evidence-grounded. We summarize mechanistic literature and clinical trials, but treatment decisions belong to you and your clinician.

Is this for clinicians or consumers?

Both. The mechanistic content is technical enough for clinicians; the recipes and safety content is accessible to everyone. Members read for whatever depth they want.
