Although there are so many products claiming and promising of a better result than others, remember that nutrition will always be the key. However, a supplement may also add up to your overall fitness and health, especially when training for a competition.

If you are always monitoring your health when you run on a day-to-day basis, you will also be conscious of what you eat. Thus, you will need to get enough nutrients, minerals, and vitamins to pursue your training.

But nowadays, you will have a hard time keeping up with proper nutrition because of your tight schedule and other responsibilities. It is the reason why you need to keep up by taking supplements.

That’s why our fitness experts have put together the five essential supplements that runners will benefit most not only used for running outside but also for running inside and hit the treadmill. Bear in mind that these supplements are also found in many food groups and are safe to consume.

I. ​​Iron Supplement To Fight Your Fatigue

​This supplement is especially important for female runners because they are more prone to iron deficiency than males. Why? It is because female athletes undergo menstruation every month, which adds up to the risk of having anemia.

Moreover, studies have claimed that runners are very prone to iron deficiency. Although the reason is still unclear, it may point out to the reason that of excessively sweating during training.

If a runner may experience anemia, he or she may feel abnormally fatigued on his or her everyday life. Fatigue may decrease the capacity to keep on going and make training so difficult to handle. 

If you are a runner and your iron levels are low, you should try taking iron supplements, particularly ferrous sulfate.

For women, they could take up to 15 grams of iron, while men could take 10 grams each day. And because iron helps in muscle oxygenation, it will assist in enhancing the VO2max, which can increase an athlete’s performance

II. Calcium Supplement For Your Bone Density

People should understand the connection between calcium and bone density. You see, low calcium levels may cause osteoporosis, and having osteoporosis will end your running career. 

Thus, you need to take it seriously. But, if you get enough of calcium in your meals, then you won’t have to worry.

However, in a study by the Cooper Clinic, results have claimed that 75% of runners have lacked vitamin D. Vitamin D helps the body absorb calcium found in food to keep your bones strong and away from the risk of fractures and injuries from running.

So, you may need the combination of vitamin D and calcium for better absorption.

III. Caffeine Supplement To Boost Up Your Performance

Caffeine serves as a performance enhancer among many athletes. More than 2/3 of the total population of Olympic athletes gain performance through caffeine supplements.

Other than boosting up your mental alertness and sharpness, it also helps in increasing your body’s capacity to turn fat into energy.

It also helps in increasing reacting time and coordination. Plus, it helps you get rid of the insight of effort to make your running effortless and natural.

Besides, caffeine also helps you recover after running. But, it will only assist you if used with carbohydrates. Recent studies have proven that drinking supplement containing caffeine and carbs will help your body recreate glycogen storage up to 66%.

And if you want enhanced performance, you will want to consume caffeine immediately during or before your runs. Experts suggest that the intake of caffeine per day is approximately 550 milligrams, which is equal to around five cups of your favorite coffee.

IV. ​Whey Protein To Sustain Your Nutritional Needs

Protein is a vital nutrient in the body, especially for muscle growth. It composes around 17% of a person’s total body weight. Plus, it helps in your body regulation, and it maintains normal processes, including hydration, cellular healing, and fluid balance.

For daily consumption, protein is equal to around 0.36 grams per pound of weight. Although a lot of people take up more than the protein they need, runners still need a demanding amount of protein to sustain their proper nutrition.

As an athlete, you should consider consuming whey protein since it does not contain so many calories.

But, how can whey protein boost up your abilities as a runner? Whey protein restores the protein that you break down as you go running. It also aids you in building up lean tissue, which helps in your general muscle healing.

If your protein becomes lower than normal, you are more prone to injuries, and you may even lose more muscle mass. For runners, the recommended whey protein supplement is approximately 40 to 60 grams each day.

Remember to take whey protein before you start your daily runs for faster muscle recovery. However, if you opt to take it after your training, it will still work.

V. Creatine For Your Muscle Growth And Retrieval

Although many perceive that creatine is for weight lifters, it is not always the case! Every athlete will need some amino acid to get through their training. Creatine can even boost up your capacity for enhanced muscle growth and recovery process.

When you engage in running, creatine helps offset the adverse effects of cellular damage and muscle soreness and inflammation.

If you consume creatine supplements on a daily basis, it may lower your submaximal VO2 levels. It enables your body to use up oxygen more efficiently while you are active. It also helps you run faster in hot weather as it enhances your body’s capacity to remove sweat, and improves your heart rate.

A lot of runners consume creatine in the “loading phase” and in the “maintenance phase”. The loading phase lasts up to five days to create the requisite creatine levels, which is about 20 grams per day. The maintenance phase, on the other hand, will require about five grams of creatine per day.

​With the five supplements mentioned above, we have gathered the five best supplements for runners available on the market. Here are as follows:
