Our body requires essential vitamins and minerals to function normally. A healthy lifestyle, therefore, not only serves for physical well-being but also serves one's own psychological well-being. A wholesome and balanced lifestyle is necessary. Yet, our busy modern lifestyle may not be the best to cater a balanced and holistic lifestyle. Many may not intake enough essential vitamins and minerals, especially when the body requires extra vitamins and minerals, such as growth and pregnancy. Supplements and health devices, therefore, may support this kind of modern lifestyle.
