Fish Oil
Description
Fish oil is derived from the tissues of oily fish and is a rich source of omega-3 polyunsaturated fatty acids. These essential fatty acids, particularly EPA and DHA, are crucial components of cell membranes and play a significant role in various physiological functions throughout the body. The primary active compounds, EPA and DHA, are vital for brain development and function, vision, and immune system regulation. They are incorporated into phospholipids in cell membranes, influencing membrane fluidity and cell signaling pathways, which are critical for overall cellular health. Fish oil supplements are widely used to increase the intake of these beneficial omega-3s, especially for individuals who do not consume enough oily fish. It is recognized for its anti-inflammatory properties and its contributions to maintaining cardiovascular, neurological, and joint health.

Anti-Inflammatory Support
Impact
Highest effect
Typical dose:1000–3000 mg
Fish oil is a foundational supplement for managing inflammation. Its components, EPA and DHA, are incorporated into cell membranes and enzymatically converted into specialized pro-resolving mediators (SPMs) that actively turn off the inflammatory process. This helps reduce chronic inflammation and supports cardiovascular and joint health.

Cardiovascular Support
Impact
Highest effect
Typical dose:500–2000 EPA+DHA mg
Rich in the Omega-3 fatty acids EPA and DHA, which are integral to cell membranes throughout the body. They have extensive clinical evidence for improving lipid profiles (especially triglycerides), reducing systemic inflammation, and supporting endothelial function, which is critical for blood vessel health.

Typical dose:500–2000 EPA+DHA mg
The Omega-3s EPA and DHA are crucial for resolving inflammation throughout the body, which is a key factor in long-term health. They are integral components of brain cell membranes, supporting cognitive function, and also play a significant role in maintaining heart health and healthy blood lipid levels.

Energy
Impact
High effect
Typical dose:500–2000 EPA+DHA mg
The omega-3 fatty acids EPA and DHA are integral components of mitochondrial membranes. Healthy membranes allow for more efficient energy production (ATP synthesis). Additionally, their anti-inflammatory properties can combat the low-grade inflammation that contributes to feelings of fatigue and malaise.

Testosterone Support
Impact
High effect
Typical dose:500–2000 EPA+DHA mg
The health of cell membranes in the Leydig cells of the testes is critical for proper hormone production. Omega-3s improve membrane fluidity and function. Studies suggest that higher omega-3 intake is associated with improved testicular function and higher levels of Luteinizing Hormone (LH), a precursor signal for testosterone production.

Interactions
Positive Interactions
Vitamin E
Protects omega-3 fatty acids from oxidation, maintaining their potency and efficacy.
Vitamin D
Fish oil, being a fatty acid source, can enhance the absorption of fat-soluble vitamins like Vitamin D.
Coenzyme Q-10
Offers synergistic benefits for cardiovascular health and acts as an antioxidant.
Curcumin
Demonstrates synergistic anti-inflammatory effects when combined with fish oil.
Astaxanthin
Provides synergistic antioxidant and anti-inflammatory benefits, with absorption potentially enhanced by the fats in fish oil.
Lycopene
Absorption of this fat-soluble antioxidant may be enhanced by the presence of fats from fish oil.
carotenoids
Absorption of these fat-soluble antioxidants may be enhanced by the presence of fats from fish oil.
Negative Interactions
Ginkgo
High doses of fish oil, when combined with Ginkgo, may increase the risk of bleeding due to potential additive antiplatelet effects.
Vitamin K
High doses of fish oil may interfere with normal blood clotting mechanisms, potentially impacting the effectiveness of Vitamin K, which is crucial for coagulation.
