How Vitamin B12 and Folate Support Healthy Blood

Vitamin B12 and Folate work together to form and mature these cells.
If either vitamin is missing:
- Red blood cells become large, weak, and irregular

- This leads to fatigue, low energy, and pale skin
This condition is known as Megaloblastic Anemia.
So, getting enough of both vitamins is essential to prevent anemia and maintain oxygen flow in the body.
