Best Amino Acid Supplements
Criteria Used for Evaluation
Most of these offer similar benefits, but some manufacturers have other items also packed into their combinations that you may feel you need or don’t need. These types typically offer three key benefits that will help you obtain more endurance for your workouts. First, the amino acids will help you feel more energetic prior to your workout. Many of them are developed to be taken a certain amount of time before you exercise so that by the time you exercise, you’ll feel the energy lift. Of course, the more energetic you feel, the more working out you’ll be able to do, and the stronger you’ll get. That is why a proper diet for runners is crucial.
Second, they are designed to help you build up lean muscle faster as you exercise. Amino acids help you retain muscle tissue better after every exercise, meaning that you’ll get stronger faster than if you worked out without using them. Since strength is a key factor in obtaining better endurance, this is a huge plus.
Third, amino acids help to prevent fatigue and muscle soreness after you are done with your workouts. Since they help provide better blood circulation to your muscles, you won’t feel as much pain and you’ll recover much faster. That will allow you to work out more often, feel less pain, and achieve your endurance and strength goals much faster.
Some of these products offer other benefits, like electrolytes for a hydration boost, for instance. Whether you need electrolytes or not is up to you, and it depends on your diet and any other sports drinks you might digest either pre or post-workout.
These types usually feature several different types of amino acids in them, and the combination types of specific amino acids can vary. On top of the amino acids packed into them, sometimes you’ll also find other beneficial ingredients, in them, like caffeine or electrolytes.
There are two very common combinations of amino acids, although not all products offer one of these two combinations. The first combination is leucine, valine, and isoleucine. This combination of amino acids usually focuses on helping your body quickly build up muscle, meaning you’ll get stronger faster and obtain more endurance through your workouts. While you’ll also get a pre-workout energy boost and faster muscle recovery as well, this combination’s main strength is building up lean muscle quickly.
The second combination is leucine, glutamine, and citrulline malate. That combination offers an effective energy boost as the major benefit focus. While you’ll also get the faster muscle build-up and the muscle recover benefits, you’ll feel a stronger energy boost with that combination.
Some of these products also pack in a small dose of caffeine into them, and since you take them prior to your workout, the caffeine will help give you more energy and stronger mental focus before your exercises. Any supplement with caffeine in it will also provide a nice energy lift before your workout.
Occasionally, you’ll also find electrolytes in some of these products. Electrolytes are included in some of these products because electrolytes help boost your hydration so that you won’t dehydrate and you feel better during your workout.
How effective the endurance increase you get from the supplement you pick is going to be important. Since different products offer different benefit levels, how you measure an endurance increase depends on a few factors. First, all of these types of products are made to help you build up muscle faster so that you become stronger, and that will increase your endurance levels overall.
Second, these products will help you feel less soreness and fatigue so that your muscles recover faster, often increasing your ability to work out more often, and also to work out for longer. Obviously, by doing that, you’ll gain more endurance as well.
Third, these products are meant to be taken prior to your workouts, so you’ll actually feel an energy boost when you start exercising. Some of them add caffeine to their ingredients so you really feel more energy, and others rely on more natural methods. Caffeine will give you a better pre-workout energy boost, but not everybody is into relying on caffeine for this, so that will be a matter of personal preference for you.
The value of these products can be measured by what they offer to you, and how much they cost. Most of the products on this list don’t cost too much, but some are more expensive than others. However, even if you wind up buying something that costs less, you should still get a lot of endurance to help out of the product. So, don’t worry about having to stay in your budget, since you’ll still find a great product.
