The Omega-3 Supplementation Guide
A blueprint for choosing the right fish oil supplement — filled with specific recommendations, guidelines for interpreting testing data, and dosage protocols.
Most of the cholesterol in our body is made by the body itself and minimally influenced by the cholesterol we eat. The recommendation to limit dietary cholesterol to less than 300 milligrams per a day was not backed by quality research and is no longer recommended. In addition, saturated fat increases large LDL, but not the more harmful small LDL. As a result, there is little evidence to support the theory that saturated fat increases heart disease risk. Dr. Krauss believes that the foods in which the nutrients are consumed are more important than the nutrients themselves. For example while saturated fat alone is not strongly associated with heart disease risk, red meat is high in saturated fat and has been strongly associated with heart disease risk. In this clip, Dr. Ronald Krauss debunks common myths of dietary cholesterol and saturated fat.

A type of lipoprotein. LDL is formed in the liver and transports lipid molecules to the cells. Often referred to as the “bad cholesterol,” LDL can drive the progression of atherosclerosis if it becomes oxidized within the walls of arteries. LDL particles exist in different sizes, ranging from large, fluffy molecules to small, dense molecules. Some evidence suggests that LDL particles increase the risk of developing heart disease, whereas the large, fluffy type of LDL may be cardioprotective.[1]

- Omega-3 supplementation combined with exercise improves body composition and cardiometabolic health more effectively than exercise alone, including a notable 10% decrease in triglyceride levels.
- Engaging in 30 minutes of vigorous daily exercise can offset up to five years of age-related heart health decline, but long sitting durations may undermine this benefit.
- Strawberry consumption boosts thinking speed and lowers systolic blood pressure by 3% in older adults.
- High-intensity interval training reduces arterial plaque size by 1.2% in coronary artery disease patients after six months, potentially slowing or reversing disease progression.
- Long-term, high-dose omega-3 supplementation—2 to 4 grams daily—effectively improves heart function in people with heart failure.
