Micronutrients & recovery
Chronic metabolic stress from aging and high-fat feeding causes systemic carnitine insufficiency, characterized by reduced skeletal muscle free carnitine levels and compromised mitochondrial fuel switching.
Aging and chronic overeating can deplete your body's natural carnitine stores, particularly in muscle. This depletion impairs your mitochondria's ability to switch between burning fat and sugar efficiently, contributing to insulin resistance.

Consistent with this prediction whole body carnitine dimunition was identified as a common feature of insulin-resistant states such as advanced age, genetic diabetes, and diet-induced obesity.
Why this rating
Consistent findings across multiple rodent models (ZDF, HF, aging) and strong correlation with insulin resistance.
