Each Astaxanthin softgel typically provides:
AstaPure® Astaxanthin Oil 42mg (providing Astaxanthin Oleoresin 4mg)

Typically Astaxanthin Oil comes in a maximum of 10% output of Astaxanthin. So you will commonly see products advertised for 12mg of Astaxanthin for relatively cheap - the reality is you are getting 12mg of material but maximum output from that will be 1.2mg Astaxanthin - sometimes even less. 

We use very high grade AstaPure® Astaxanthin to ensure you get a concentrated and standardised extract delivery, providing at least 4mg of Astaxanthin Oleoresin in each softgel.
