Dr. Rick's Insights

What’s the Difference & Better Creatine Supplement? By Dr. Rick Cohen, M.D. Creatine remains one of the most scientifically supported supplements in sports and clinical nutrition — enhancing strength, muscle performance, and recovery. Yet new delivery systems, such as liposomal creatine, have emerged with claims of improved absorption and fewer digestive side effects. So what does the research suggest? And how does it compare to traditional creatine monohydrate? What Is Liposomal Creatine? Liposomal creatine is a next-generation formulation where creatine molecules are encapsulated inside microscopic lipid (fat) spheres called liposomes. These structures protect creatine from degradation in the digestive tract...

What the Research Actually Shows By Dr. Rick Cohen, M.D. Over the past decade, scientists have begun uncovering a fascinating relationship between omega-3 fatty acids and testosterone regulation in men. While omega-3s are best known for supporting heart and brain health, emerging evidence shows they also influence hormone production, testicular function, and inflammation balance — all key elements in maintaining healthy testosterone levels. Why Omega-3s Matter for Hormonal Health Omega-3 fatty acids — primarily EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) — are structural fats incorporated into every cell membrane in the body, including those of the testes, pituitary, and...

Omega-3 Fatty Acid Testing By Dr. Rick Cohen, M.D. The Omega-3 Index Test is one of the most evidence-based biomarkers of long-term heart and brain health. This simple blood test measures the percentage of key omega-3 fatty acids—EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid)—in red blood cell membranes, providing insight into cardiovascular resilience, inflammation balance, and cellular performance. Unlike short-term plasma levels that fluctuate with meals, the Omega-3 Index reflects long-term intake and tissue integration of omega-3s over the previous 3–4 months. What Is the Omega-3 Index? The Omega-3 Index represents the combined percentage of EPA and DHA in red...

What Is Magnesium Glycinate? By Dr. Rick Cohen, M.D. Mag Glycinate 510 provides a highly absorbable clinical dose of magnesium — one of the most critical yet commonly deficient minerals in modern health. Magnesium supports more than 300 enzymatic reactions, influencing energy, muscle function, heart rhythm, and brain performance. Over half of adults in the United States fall short on daily magnesium intake, leading to fatigue, cramps, poor sleep, and even elevated stress or anxiety. Magnesium glycinate is a chelated form of magnesium in which magnesium is bound to the amino acid glycine. This structure enhances absorption and minimizes digestive...
