Talk to a clinician first
This is a supplement we won’t link to a specific product without clinician context. Once we offer clinician partner pathways, this is where they’ll appear.
If you’re working with a doctor or qualified practitioner, they can advise on dose, brand, and monitoring.
Your experience
If you’ve tried Spirulina, you can log how it went. This stays on your device — only you see it.
We frame these as personal experience, not medical claims. Self-reported subjective outcomes are influenced by placebo, regression to the mean, and parallel lifestyle changes. We’ll never present ratings as equivalent to RCT evidence.
