Marrow vs. Fish Oil: The Better Fat Source for Brain Health Why Healthy Fats Matter for the Brain

Your brain is nearly 60% fat. That means the quality of fats you eat directly impacts focus, memory, and mood. For years, fish oil has been the go-to supplement for brain health, thanks to its omega-3 content.

But fish oil isn’t perfect — and there’s an older, more complete source of brain-friendly fats that’s been overlooked: bone marrow.

The Downsides of Fish Oil

Fish oil isn’t bad — but it comes with baggage:

• Oxidation risk → fish oil spoils quickly, and rancid oil is harmful.
• Contamination → heavy metals and PCBs can be found in poorly sourced oils.
• Fishy aftertaste & burps → one of the top complaints.
• Limited nutrient profile → mostly DHA and EPA, without supporting co-factors.

In other words, it’s helpful, but not the full package.

Why Bone Marrow Is the Smarter Brain Food

Bone marrow has been a prized food in ancestral diets for thousands of years. Modern science shows why:

• Omega-3 fatty acids → support brain cell structure and signaling.
• CLA (conjugated linoleic acid) → helps regulate inflammation and metabolism.
• Vitamin K₂ → directs calcium away from arteries and into bones, while also supporting brain health.
• Alkylglycerols (AKGs) → immune-supporting fats also linked to resilience and cell health.
• Healthy saturated fats → fuel for brain energy and hormone balance.

Instead of a single nutrient, marrow delivers a broad spectrum of fats and co-factors your brain can actually use.
