Proper intake of vitamins and micronutrients plays a vital role in supporting metabolic function, strengthening the immune system, maintaining cellular health, and reducing oxidative stress. Deficiencies in essential nutrients such as Vitamin D, B-complex vitamins, Vitamin C, and key minerals may negatively affect energy levels, neurological function, and overall well-being. For optimal absorption and effectiveness, dietary supplements should be used according to individual nutritional needs and preferably under the guidance of a healthcare professional or nutrition specialist.
