Astaxanthin supplements are promoted as increasing physical endurance, reducing inflammation, and lowering triglyceride levels. But can they really do this? Also, astaxanthin supplements are relatively expensive, with some costing more than $1 per day. Which supplements have what they claim and are the best value?
To answer these questions, ConsumerLab.com recently reviewed the scientific evidence for astaxanthin and selected and rigorously tested popular astaxanthin supplements. Testing determined the amount and form (natural or synthetic) of astaxanthin. ConsumerLab.com also checked levels of lead, cadmium, arsenic and mercury in each supplement to determine if any were contaminated with heavy metals — a potential concern because astaxanthin is typically produced from algae.
Our tests identified many high quality products which contained what they claimed and were not contaminated with heavy metals. However, we found that among these, cost varied widely: Some quality products were 3 times more expensive than others for the same amount of high-quality astaxanthin.
