Short answer

Take it with a meal that has fat, because astaxanthin is a fat-soluble carotenoid. Time of day doesn't matter; taking it consistently does.

Full Protocol

Timing
Take it with a meal that has fat, because astaxanthin is a fat-soluble carotenoid. Time of day doesn't matter; taking it consistently does.
Dosage
4-12mg daily is the commonly studied range. It is taken in one daily stack, with no dose disclosed (Bryan Johnson).
Form
Natural astaxanthin from microalgae is the most common supplement form. Synthetic astaxanthin offers scale, purity, consistency and possibly better absorption (David Watumull, on The Doctor's Farmacy). Food sources include salmon (especially wild), salmon roe, krill oil, shrimp and lobster; their red-pink color comes from astaxanthin.
Notes
Astaxanthin has a strong safety record, including long use in animal feed (David Watumull, on The Doctor's Farmacy). As a carotenoid, it does not turn into vitamin A, so there is no vitamin A toxicity risk. The ITP lifespan gain was seen only in male mice, and the sex difference needs more study.

    The timing of administration greatly affected astaxanthin bioavailability including the area under the curve (AUC(0-168), 2,968 + or - 959 microg h/l in the before-meal group vs. 7,219 + or - 3,118 microg h/l in the after-meal group), indicating high availability in the after-meal group.
