Minerals
Chromium
A trace mineral that enhances insulin sensitivity.
Chromium potentiates the action of insulin, improving glucose uptake into cells and supporting healthy blood sugar regulation. This is relevant for longevity because insulin resistance and elevated blood sugar are major drivers of aging, cardiovascular disease, and neurodegeneration. A systematic review found that chromium supplementation improved HbA1c and fasting glucose in people with type 2 diabetes.
Dosage
RDA: 35mcg for men, 25mcg for women (adequate intake)
Optimal for longevity: Researchers suggest 35-200mcg daily, particularly for individuals with blood sugar concerns.
Deficiency signs
Difficult to assess due to lack of reliable biomarkers; marginal deficiency may be common in diets high in refined carbohydrates
- Blood sugar fluctuations
- Increased hunger and cravings
- Fatigue after meals
- Difficulty losing weight
