I usually use Viva Natural's Astaxanthin, but when they were out of stock on Amazon, I started looking for an alternative. I came across Cheeky Nutrition's Astaxanthin. Most of the Astaxanthin's available have soy oil in them, and other not so great ingredients. Although it is not made with olive oil , (which I wish they would would consider instead of sunflower oil) for the price, and quality, I believe this brand's Astaxanthin is worth looking into, and purchasing. FYI it is manufactured in the UK, which has stricter guidelines than the US. 6 month's supply for $20. You can't beat quantity ,with quality, for this price!
