Endurance runners put their bodies under physical stress for hours. Intervals, tempo, and long runs sap the body of all the resources that it has. Runners need appropriate and sufficient nutrition, and hydration to recover and adapt to ever-increasing loads. Apart from their macro/micro-nutrient requirements, many endurance runners seek supplements with their desire to improve their performance.
This article will provide essential information about supplements, specifically for endurance runners. Before we begin, let us define and clarify some concepts.
There are supplements and there are ergogenic aids. Many times, these are used interchangeably. To guide our readers, we will follow the below-mentioned definition.
|Supplements raise your health to baseline levels.||Ergogenic aids raise your physical and mental performance above your baseline levels|
|Supplements can be used when the body is deficient in certain nutrients and obtaining the nutrients from food is not viable.||Ergogenic aids raise your performance without any consideration of your nutritional deficiencies.|
|Supplements are mostly food-based.||Ergogenic aids can be food, drugs, mechanical aids, blood transplants, etc.|
|Supplements are mostly legal, yet it makes sense to consult a nutritionist||Ergogenic aids may or may not be legal. It is imperative that one consults nutritionists on its legality.|
A simple analogy can help differentiate between supplements and ergogenic aids. Imagine your body to be a car. Nutrients and Supplements are gears and fuels in the car. Whole food provides appropriate nutrients to keep the car conditioned that might wear due to use. It also supplies sufficient fuel for the car to run optimally. Ergogenic aids are nitro-fuel that is added on top of your fuel to enhance the speed of the car.
So it makes sense that one keeps the car in good condition and replenishes the fuel in the car first before adding nitro-fuel to enhance performance.
Although most of the nutrients can be obtained from food, there could be several reasons why the nutrients from food may not be a viable source
Before considering specific supplements, one must understand nutritional deficiencies that are commonly observed in endurance runners. In general, nutritional deficiencies are due to the following factors:

In no specific order, the top nutrition deficiencies observed in endurance runners are
|Deficiency can cause|
Additionally, there are specific energy and mineral requirements that are needed during endurance runs so that runners don’t bonk during long runs. These are
Below are broad guidelines on when to take the supplements. It is recommended that one consults a nutritionist or a doctor before taking the supplements.
|Iron||On an empty stomach, preferably early morning||If the stomach gets upset, then have it near meals. Have it with vitamin C or food containing Vitamin C as it helps in absorption|
|Vitamin B12||Early morning preferably on an empty stomach||If the stomach gets upset, then have it near meals.|
|Vitamin D||Have it with meals for better absorption||Preferably have it with Calcium supplements|
|Calcium||Have it with meals||Preferably have it with Vitamin D|
|Zinc||2 hours before or after meals||Don’t have it on empty stomach|
|Magnesium||Closer to bedtime||It helps relax the body. So preferably have it just before bed.|
In the quest for finding supplements, most endurance runners miss two very important macronutrients: Proteins and Essential Fatty Acids
There is a mistaken belief that **proteins **are only needed for bodybuilders or weightlifters. Endurance running causes lots of wear and tear in the muscles, tendons, bones, etc. Proteins are needed not only to repair but also to build necessary adaptions to the stress & load.
Most runners, don’t pay heed to essential fatty acids. Fats along with carbohydrates are taken for granted because it is abundantly used in most cooking around the world. However, these fats may not contain essential fatty acids.
Essential fatty acids are needed for proper cellular function, hormone production, development, and functioning of the nervous system.
It is very difficult to figure out protein and essential fatty acid deficiencies from biomarkers. We recommend that endurance runners get their diet checked by sports nutritionists to ensure that their diets have proteins and essential fatty acids in the right amount.
|Protein||After workouts, have a fast-absorbing protein like whey.
Before bed, have a slow-releasing protein like casein so that your body gets a steady dose of protein when the body is recovering during the night
|Keep the quantity of protein supplementation to 20-30 grams per dosage.
Spread the dosage across the day so that the body has a steady dose of amino acids rather than large dosages at the far ends of the day.
|Essential Fatty Acids||Anytime of the day, along with meals||Fats get along better with other fats in the meals. Having it on empty stomach may cause acid reflux.|
There are various minerals, compounds, elements that are touted as ergogenic aids. Very few are legal. Out of the ‘legal’ ergogenic aids, most do not have enough evidence to claim that they can help improve running endurance. However, many nutritionists and many firms use few articles or studies as evidence to sell ergogenic aids. Very few ergogenic aids have meta-studies proving the efficacy. Here are a few of them who are helpful for endurance running.

Before anyone starts experimenting with ‘Ergogenic Aids’, we recommend that runners get their nutrition in order. Once they know that there are deficiencies that cannot be fixed with food alone, supplements can be taken. After this, runners can focus on Ergogenic aids.
We recommend that endurance runners get their vitamin & minerals profiles checked. Based on the report, then get either a doctor’s prescription or nutritionist’s recommendation or both to fix the deficiencies.
We also recommend that you first focus on deficiencies related to your demographics and then focus on occupation/sports-related deficiencies.
