NutriStack
Krill Oil and Omega-7, a synergy.
Krill oil supplies omega-3s in phospholipid form plus astaxanthin, complementing omega-7 palmitoleic acid for lipid and metabolic support; many sea-source omega-7 products are co-formulated with marine omega-3s.

Synergy
What is happening. Krill oil supplies omega-3s in phospholipid form plus astaxanthin, complementing omega-7 palmitoleic acid for lipid and metabolic support; many sea-source omega-7 products are co-formulated with marine omega-3s.
Mechanism. Palmitoleic acid supports insulin sensitivity and lipid metabolism while krill phospholipid omega-3s and astaxanthin add anti-inflammatory and antioxidant activity, giving complementary metabolic effects.
Recommendation. Reasonable to combine and take with food. Be aware that some omega-7 sources (for example, certain fish-derived oils) already contain omega-3s, so account for total marine oil intake.
