Best Selling Vitamins 

Vitamins have many functions in the human body, from supporting your immune system to keeping your skin and hair looking as healthy as possible. Many supplements combine multiple vitamins into a single pill, making it even easier to increase your vitamin intake. In addition to single bottles of vitamins, GNC has a Vitapak program designed to make it easy to get the right nutrients based on your age and health concerns. Each Vitapak program comes with a combination of nutritious products in one daily and convenient pack. Some of GNC’s best selling multivitamins and Vitapak programs can be found in the GNC Women’s and GNC Mega Men® brands. 

Best Selling Supplements 

Fish oil is one of the best selling supplements due to its high concentration of omega-3 fatty acids. The two key types of omega-3 fatty acids are EPA and DHA, which support heart, brain, skin, eye, and joint health. If you don't get enough in your diet, taking a supplement can help make up for what you're missing.  

Testosterone supplements are also one of the best selling supplements on the market. As men age, their testosterone levels tend to decrease, leading to reduced energy levels and  libido. Testosterone supplements are designed to support men’s testosterone levels, making them popular among bodybuilders and other fitness enthusiasts.  

Best Selling Protein Powders 

Other best selling health products help users feel their best, including high-quality protein powders. Protein is crucial to supporting healthy muscles, but many foods containing protein also contain high levels of fat or sugar. That’s why a protein powder or drink can be a great option!  

Best Selling Energy Drinks 

If you need a pick-me-up during the day, consider a caffeinated energy drink. It's important to look for a product that doesn't have as much sugar as soda and other sweetened beverages.
