When we think of muscle development or gains, the only nutrient we focus on is protein. However, the protein you consume is not entirely beneficial if it is not assimilated and utilised correctly. Vitamin B12 foods play an important role in this process. If your goal is to build muscle fast, you need to ensure that your daily intake of b12 foods is well-regulated. 

B12 Foods Benefits

Vitamin B12 foods are just as important in muscle gain as macronutrients. They help improve your protein metabolization and boost your training performance. Here are some benefits of b12 rich foods that help you boost your gaining cycle: 

1. Protein and Fat Breakdown

This is the primary function of vitamin B 12 rich foods. They help metabolise the proteins that you consume to be broken down into amino acids. These amino acids are absorbed directly into the muscles, allowing them to repair themselves and grow in size. Vitamin B12 also helps metabolise fats to produce energy. This is one of the primary reasons for fatigue in individuals who have a Vitamin B12 deficiency. 

2. Synthesis of Red Blood Cells 

Vitamin B12 and biotin rich foods are known to help improve the synthesis of red blood cells. This is very important for bodybuilders and athletes as the red blood cells are responsible for transporting oxygen to various organs. With increased red blood cell synthesis, the energy levels are elevated as oxygen supply to vital organs is also boosted. This helps improve overall training performance which is vital to building muscles faster. 

3. Healthy Neurological Function 

Vitamin B12 rich foods are also known to improve your neurological function. This is important for muscle control. When you have better muscle control, your performance during weight training also improves. It also reduces the chances of any injuries that may prevent you from being consistent with your training.

To consume a Vitamin B12 diet that supports your muscle gain goals, you need to consume suitable food sources. Here is a list of the best foods to improve your Vitamin B12 intake:
