Which supplements should you use?
There is a variety of different supplements with all of them carrying unique purposes and benefits. Some supplements can help you stay focused and feel more energized, some can help maximize muscle growth, and some can be beneficial to your overall health in general. Below we will be covering the 3 main types of supplements that you can/should use on a daily basis.

Vitamins are a crucial supplement for people who have deficiencies in certain areas of nutrition. The most common vitamins people take are Fish Oil, Vitamins B and C, Magnesium, and Iron. Vitamin deficiencies occur when an individual either has a poor diet or fails to consume enough food in relation to how much energy they're exerting throughout the day. Vitamin deficiencies can affect your ability to exercise consistently and can lead to an increase to health risk or injuries.

Protein powder can help maximize muscle growth, repair muscle tissue, and make enzymes and hormones. Protein powder helps aid in weight management, muscle growth, recovery after exercise, and aids in meeting recommended daily nutrient goals. The two main types of protein powders are whey and casein. Whey is a water-soluble milk protein which is the most common form of protein. Whey contains all the amino acids that the human body usually obtains through food. The body absorbs whey quickly and easily. The next common protein powder is casein. Like whey, casein contains all of the essential nutrients for the human body. The only difference is that casein is a slow acting protein meaning its takes your body longer to digest it so this protein is best to be taken before bed.

Pre-workout is beneficial in many different ways. Pre-workout has caffeine within the product and can help keep you energized and keep you focused. For individuals who don't like coffee but need caffeine to stay awake pre workout is great for you. Pre-workout also helps with recovery and ease the fatigue through an intense workout. This supplement is meant to be taken 15-30 minutes before you workout for maximum efficiency.
