It can also make our heart healthier by lowering our cholesterol and blood pressure, which are like numbers that tell us how healthy our heart is. So, taking NAC can help us feel better and stay healthy.
  • It even boosts our immune system by making more white blood cells and T-cells to fight off infections.

It’s important to talk to a doctor before taking NAC to make sure it’s safe for you. Taking too much could cause side effects like nausea or headaches, so it’s best to follow the recommended dosage.
