Hi  – astaxanthin is an antioxidant found in various seafoods and is what gives them that red/pink color (ex. salmon).

There’s a ton of research on its benefits and it’s rather safe for anyone to take. The general dosage recommendation is between 6 to 8mg and doses of up to 20-50mg astaxanthin have been tolerated, although the exact toxicity and upper limit is not known. If you’re interested in the studies, you can read more about it here.

The seafood source is always key – I like the one from Dr. Mercola for that reason. It’s lab controlled so no contamination. It’s available in the B Better Fullscript dispensary here.

As with any supplement, I do recommend cycling on and off of them every few months. The same goes for astaxanthin. It’s a powerful antioxidant which can help act as a natural sunblock, so I always time my “on astaxanthin” months during the summer to help prevent sun damage.
