11 supplements for people who work out that you can buy on Amazon

Fitness gurus recommend workout supplements as one way to maintain muscle mass and speed recovery after a rigorous routine. These supplements are typically taken pre-workout or after exercising. Pre-workout supplements target performance, while post-workout supplements target recovery. 

Make sure you match your use of pre-and post-workout supplements to your activity. Endurance-type sports like biking, running and swimming require more carbohydrates to replace glycogen stores in the liver and muscle. If you are strength training, you may need fewer carbs but more protein.

These picks include 10 best-selling supplements you can find on Amazon. If you're an Amazon Prime member, you can have them delivered to your door in 24 hours. You can join or start a 30-day free trial to shop.

Creatine can be taken either before or after a workout to help increase muscle mass and performance over time. Try Nutricost Creatine Monohydrate Micronized Powder 500G, on sale for 40% off at around $20 on Amazon.
