Not all sports are created equal. Football, for instance, is among the most physically demanding. To be their best on the field, football players tend to require more supplements than athletes in certain other sports. (See Muscle-Building Supplements That Actually Work.)

But supplements for football players can be expensive, so it’s important to know which ones are most helpful. If you’re a football player, here are some of the best:

Vitamin B12

Acccording to The Academy of Nutrition and Dietetics, vitamin B12 helps transport oxygen to red blood cells and tissues, boosting blood flow and increasing endurance so you can work harder, faster and longer.

Branched Chain Amino Acids

BCAAs are essential nutrients that build muscle protein and reduce perceived fatigue. The most important BCAAs are isoleucine, leucine and valine.

Omega 3s

Found in fish oil supplements, omega 3 fatty acids speed recovery and help alleviate sore muscles. They may also increase overall cardiovascular efficiency and improve joint health.

Pickle Juice

This relatively inexpensive supplement is used to replenish vital electrolytes lost during intense training. It’s also been proven to work wonders for relieving leg cramps. A 2010 study in the Journal of the American College of Sports Medicine found that drinking pickle juice relieved cramps faster than a sports drink or pure water.
