Not all omega-3 supplements are equal. Natural Stacks' Krill Oil is built around a single insight: the way omega-3 fatty acids are delivered to your cells matters as much as the dose. Unlike standard fish oil, where EPA and DHA are carried as triglycerides, krill oil binds these fatty acids to phospholipids - the same structure as your cell membranes - which research suggests may result in significantly better bioavailability.

Why krill over fish oil?

Two double-blind crossover trials support krill oil's absorption advantage. One study in 24 healthy volunteers found that krill oil increased plasma EPA and DHA more effectively than fish oil at equivalent doses [1]. A second crossover trial confirmed higher EPA+DHA incorporation into plasma phospholipids from krill oil compared to fish oil, noting an unexpectedly high free fatty acid content as a possible contributing factor [2].

Optimised DHA:EPA ratio

Most omega-3 supplements have more EPA than DHA - a legacy of low-grade fish oil sourcing. Natural Stacks flips this deliberately. Each serving delivers 160mg DHA and 80mg EPA, because DHA is the predominant structural fatty acid in the brain and nervous system. A small amount of Friend of the Sea-certified tuna oil is included to achieve this ratio.

Research in healthy elderly participants found that omega-3 fatty acids in phospholipid form - as found in krill oil - may support cognitive function, with the authors noting this effect was particularly associated with the phosphatidylcholine-bound EPA and DHA in krill [3].

1.5mg Astaxanthin per serving

Astaxanthin is a fat-soluble carotenoid produced by the microalgae Haematococcus pluvialis - the same algae that krill feed on, and the reason wild salmon are pink. It is considered one of the most potent antioxidants found in nature. Most krill oil products don't disclose their astaxanthin content; Natural Stacks provides 1,500mcg (1.5mg) per serving - substantially more than most competing products.

Anti-inflammatory support

A randomised, double-blind, placebo-controlled trial on 90 patients found that daily krill oil supplementation may significantly support the body's normal inflammatory response, with effects observed within 7 to 14 days of supplementation [4].

Sourcing and purity

Krill is harvested from the pristine Antarctic Ocean and cold-pressed immediately on board the vessel to preserve biological integrity. Each batch goes through a proprietary purification process and is lab-tested for heavy metals, toxins, and oxidation.
