Vitamins and minerals are the invisible backbone powering your immune function, energy, and recovery—but understanding their roles and relationships isn’t always straightforward.
Take vitamin A, vital for maintaining healthy skin and mucous membranes—the first physical barrier defending against infections. It supports cell development and vision. But beware: too much vitamin A supplements can be toxic, so aim for balanced intake primarily from food sources like chicken liver, eggs, and vibrant vegetables, or consider cod liver oil if dietary options are limited.
Vitamin D, our immune modulator sunshine hormone, requires magnesium for activation. Fatty fish and egg yolks provide sources, but sunlight and supplementation are often necessary to reach optimal serum levels over 75 nmol/L. This is crucial because deficiency is linked to poorer outcomes in infections like COVID-19.
Vitamin E stands as a key antioxidant shield, clearing free radicals alongside vitamin C and glutathione. Nuts and seeds are its natural sources, but quality supplements like Jarrow Formulas Toco-Sorb ensure a mix of vitamin E precursors for maximum benefit.
Vitamin K2 deserves attention, often missing from Western diets. Unlike K1 found in leafy greens, K2 (from liver, aged cheese, or natto) supports bone and vascular health, potentially beneficial in preventing deficiencies that might contribute to conditions seen in illnesses such as COVID-19.
Minerals like magnesium regulate energy production, immune cell balance, and vitamin D metabolism.
Zinc serves as an immune sentinel, reducing viral replication and supporting enzymatic pathways, best absorbed away from grains and legumes.
Vitamin C, the antioxidant powerhouse, protects cells and supports immune responses, while B vitamins fuel energy and DNA repair.
Their synergy is critical: each micronutrient depends on others, forming a network where imbalances compromise the whole system. Personalized supplementation means understanding your body’s specific needs, current status through lab tests, and health context.
