Vitamin K also supports calcium regulation in bones and arteries, promoting strong bones and cardiovascular health. It exists in two main forms: K1 (phylloquinone), found in green leafy vegetables, and K2 (menaquinone), found in fermented foods and animal products. Adequate intake is vital to maintain ...

Vitamin E is a fat-soluble antioxidant that helps protect cells from damage caused by free radicals. It plays a vital role in maintaining healthy skin, eyes, and immune function. Vitamin E also supports proper blood flow by preventing blood clots and promoting vessel health. It is found naturally in foods like nuts, seeds, vegetable oils, and green leafy vegetables. Due to its antioxidant properties, it contributes to slowing oxidative stress and may aid in reducing the risk of certain chronic d...

Vitamin D3 hydroxyvitamin, also known as 25c -hydroxyvitamin D or calcidiol, is the primary circulating form of vitamin D in the blood. It is produced in the liver when vitamin D3 (cholecalciferol) is metabolized and serves as a key marker for assessing vitamin D levels in the body. Calcidiol helps regulate calcium and phosphate balance, supporting bone health, immune function, and overall cellular processes. Measuring its levels can help diagnose vitamin D deficiencies or monitor supplementatio...

Vitamin D3, or cholecalciferol, is a fat-soluble vitamin crucial for maintaining healthy bones and teeth. It helps the body absorb calcium and phosphorus, which are essential for bone mineralization. Vitamin D3 also supports immune function, muscle health, and overall well-being. The body produces it naturally when the skin is exposed to sunlight, but it can also be obtained from foods like fatty fish, egg yolks, and fortified products, or through supplements. Adequate levels are essential to pr...

Vitamin C, also known as ascorbic acid, is a water-soluble vitamin essential for human health. It plays a key role in collagen synthesis, wound healing, and maintaining healthy skin, blood vessels, and bones. As a powerful antioxidant, it helps protect cells from damage caused by free radicals. Vitamin C also enhances the absorption of iron from plant-based foods and supports immune function. Since the body cannot produce or store it, regular intake through diet or supplements is necessary. Comm...

Vitamin B6, also known as pyridoxine, is a water-soluble vitamin essential for numerous physiological functions. It plays a key role in amino acid metabolism, neurotransmitter synthesis, and hemoglobin production. B6 supports brain development, immune system function, and the conversion of food into energy. It is found in various foods, including poultry, fish, potatoes, bananas, and fortified cereals. Deficiency can lead to symptoms like irritability, depression, anemia, and nerve-related issue...

Vitamin B2 (Riboflavin) is a water-soluble vitamin essential for energy production and cellular function.
