Nutritional supplements and vitamin types for health support

Nutritional supplements, including fish oil and various vitamins, serve as essential supports for maintaining health when balanced diets are difficult to sustain. Omega-3 fatty acids, which the body cannot produce naturally, are noted for their positive effects on cardiovascular health, brain function, and eye health. While cold-water fish like salmon and mackerel are rich in these acids, supplements provide a practical alternative. When selecting fish oil, it is important to consider EPA and DHA ratios, purity, and the absence of heavy metals.

Vitamins are categorized into water-soluble groups, such as B and C, and fat-soluble groups, including A, D, E, and K. Each plays a specific role: Vitamin C supports immunity and iron absorption; B vitamins assist in energy metabolism and nervous system health; Vitamin D is critical for bone health; Vitamin A aids vision; Vitamin E protects cells; and Vitamin K is involved in blood clotting and bone metabolism.
