Why Do I Need Nutritional Supplements?

CrossFit, in a nutshell, is a lifestyle of healthy living through exercise and proper nutrition. Whether you choose to do CrossFit to lose weight, build muscle, or both, adequate nutrition is the pillar you build your progress on. However, the energy and process to build muscles may need a little bit more than a mere healthy diet. That’s where CrossFit nutrition supplements come in.

CrossFit is all about high-intensity exercise. This type of training uses more energy, burns more fat and calories, and stimulates muscle building. Our muscles need some time to heal and to perform better. Supplements can help to build them properly. 

Nutritional supplements provide the body with the needed help to become more athletic and your CrossFit workouts to become more productive.

Before you begin supplementing:

Find out what supplements you need and which ones won't work for your DNA type before you buy them. DNA diet programs use proprietary algorithms to classify people into different diet types based on their nutritional preferences.

Gene Food identifies the most appropriate diet for you based on over 120 genetic factors. In addition, you receive personalized health and diet recommendations based on your genetics.

Your diet should match your DNA. That means you can trust your diet and supplement plan to work.

Different Types Of Supplements
