Omega-3 Recommendation for someone with heart disease
1 gram of EPA+DHA per day. Still fish first, then supplements
Omega-3 Recommendation for someone with heart disease and high triglycerides
2-4 grams of EPA+DHA per day
Supplements under a physicians supervision
How does the body break down triglycerides
hydrolysis into monoglycerides and diglyceride
What is one of the most important functions of Fat in the body?
