Key Takeaways

  • Astaxanthin did not extend lifespan in mice in a recent study due to a lower dose and altered timing compared to an earlier positive study.
  • The life-extending dose of Astaxanthin in mice equates to several grams in humans, which is impractical through supplements or food.
  • Continue taking Astaxanthin for its other benefits, including UV protection, skin elasticity, reduced inflammation, eye protection, and lipid-lowering effects.

Supplements & Protocols Mentioned

  • Astaxanthin: Dose associated with life extension in mice is several grams in humans; typically, people take 8 to 12 mg.
  • Astaxanthin: Started at 12 months of age in mice for positive effects; timing varied in the newer study.

Bottom Line

Continue using Astaxanthin for its non-lifespan-related health benefits, but be aware that achieving life-extending doses is impractical.
