When you’re feeling sluggish, eat a protein bar. Protein is essential to consume in order to maintain energy and keep the body going. It is used to help develop and maintain almost every part of the body. It makes hormones and enzymes, while also helping keep your muscles, bones, blood, and hair and nails healthy. Tip: Try Premier Protein Bars; they contain 30g of protein, no artificial sweeteners, flavors or colors, and come in a variety of flavors.
