  • Supplements That Support Optimal Health and Longevity

    The concept of longevity supplements refers to dietary supplements that are often marketed or believed to promote overall health, well-being, and potentially extend lifespan.

    Immunosenescence refers to the gradual decline in the immune system's function as a person ages. This decline affects both the innate and adaptive branches of the immune system, making older individuals more vulnerable to infections, chronic diseases, cancer, and less responsive to vaccines.

  • The role of Curcumin, Citrus Bergamot, and Berberine in supporting optimal cardiovascluar health*

    Curcumin, bergamot, and berberine offer potential benefits in stabilizing soft plaque by reducing cholesterol levels, managing inflammation, and controlling blood sugar.*

    While they can be useful adjuncts in cardiovascular health, they should be used alongside a healthy diet, exercise, and any prescribed medications. More large-scale human studies are needed to fully confirm their effects on plaque stabilization, but their natural properties offer promise for supporting heart health.

  • Carnivore? Keto? Vegetarian or Vegan? What IS the best choice? What does the evidence show?

    If you're looking for a balanced, sustainable, and evidence-backed diet, the Mediterranean diet is often considered one of the best choices. It promotes heart health, supports weight management, and is nutritionally balanced. If you have more specific health goals (e.g., improving blood sugar control), a modified Mediterranean / low-carb or paleo approach might work well. Ultimately, the best choice is one that contains little or no added sugar (read labels), is not processed, aligns with your health goals, provides adequate nutrition, and is sustainable for your lifestyle.
