DESCRIPTION: This is why I recommend 250mg a day of a pollutant-free source of long-chain omega-3 fatty acids.

Why not just eat fish or take fish oil? See:
• PCBs in Children’s Fish Oil Supplements (
• Dioxins in U.S. Farm-Raised Catfish (
• Omega 3s, Prostate Cancer, and Atrial Fibrillation (
• Fish Consumption and Suicide (
• Fish and Diabetes (
• ALS (Lou Gehrig’s Disease): Fishing for Answers (
• How Long to Detox From Fish Before Pregnancy? (
• Is Fish “Brain Food” for Older Adults (

How else can we protect our brains? See, for example:
• Preventing Brain Loss with B Vitamins?(
• The Alzheimer’s Gene: Controlling ApoE (
• Cholesterol and Alzheimer’s Disease (
• Reducing Glycotoxin Intake to Prevent Alzheimer’s (

This concludes my 2016 update of the latest science omega-3’s—I hope it was useful!
