Is it safe to have fish oil for nursing mother?which one is the best brand?

Safe and recommended: Not only is fish oil safe, but highly recommended as the best source of dha in breast milk, which is important for the health of your baby's brain & eyes. There is no single best brand but i recommend brands that have undergone "pharmaceutical-grade molecular distillation" to remove toxins & which are emulsified to improve digestion. Good brands include nordic naturals, pharmax, designs for health.

Hype: Krill oil and fish oil are the new snake oil, both are high in omega 3 fatty acids which are extremely fragile. Omega 3 fish oils reduce triglycerides by impairing the liver's ablility to make them. However the oxidative stress caused by fish oil actually raises LDL cholesterol. Some day we may use the phrase "this is just more fish /krill oil" or "here comes the fish/krill oil salesman".
