Astaxanthin Complex 4mg (42mg Oil) Microalgae 90 Vegan Softgels

What Astaxanthin Complex Provides

Each vegan softgel contains 42mg of microalgae complex oil, delivering 4mg of active astaxanthin from Haematococcus pluvialis alongside lutein and zeaxanthin — worth being clear that the astaxanthin content specifically is 4mg, not the full 42mg oil weight, which includes the carrier oil and other carotenoids. As covered in more detail in our complete astaxanthin guide, 4mg daily sits within the commonly referenced range for general antioxidant support, with some research suggesting 6-8mg specifically for eye or skin-focused goals — this product’s optional two-softgel dose (8mg astaxanthin) would fall within that higher range if you’re specifically targeting those areas.

It’s worth being accurate about the framing of the 4mg dose as somehow avoiding “temporary spikes in antioxidant levels” — this isn’t something we found established in the research, and is best read as marketing rationalization rather than a documented pharmacological consideration; the dose is reasonable simply because it matches commonly referenced research amounts, not because of any spike-related mechanism.

This astaxanthin is sourced from microalgae cultivated in closed, climate-controlled systems rather than open ponds — a genuine quality consideration, since closed cultivation generally reduces contamination risk from other, potentially toxic cyanobacteria species that can affect open-pond sourcing. The capsules use vegan seaweed-derived shells, manufactured to GMP standards in the UK, and are free from gluten, dairy, lactose, and yeast.

Astaxanthin’s research base is strongest for eye health and skin protection specifically, with more preliminary evidence for other claimed benefits — worth keeping expectations proportionate to which specific area you’re most interested in.

Take one softgel daily with a meal containing some fat for better absorption; up to two softgels daily is an option for those wanting the higher end of the research range. This product isn’t suitable for children under 3 years. Store in a cool, dry place away from sunlight. Speak to your GP before use if you’re pregnant, breastfeeding, or taking medication.
