Riboflavin's Role in Your Health

Riboflavin, or Vitamin B2, plays a crucial role in maintaining overall health. It helps convert food into energy, supports cellular function, and keeps skin, eyes, and the nervous system healthy. Deficiency can lead to symptoms like sore throat, swelling of mucous membranes, and skin disorders. Including riboflavin-rich foods like eggs, nuts, dairy, and green vegetables in your diet ensures you get enough of this vital nutrient. Supplements can also help, especially for those with dietary restrictions. Remember, balance is key. Too much riboflavin can cause issues just as much as too little. Always consult with a healthcare provider before making significant changes to your diet or supplement regimen. Understanding riboflavin's importance empowers you to make informed choices for better health.
