Why Do Runners Need Supplements?

Running puts extra demands on our bodies over and above what a regular diet can handle. Should we consider using supplements? Here's why runners might consider incorporating supplements into their routine:

  • Increased Nutrient Demands: High-intensity training uses essential nutrients at a faster rate than that used by sedentary people.
  • Enhanced Recovery: Certain supplements can accelerate muscle repair and reduce inflammation post-run.
  • Performance Optimization: Some supplements directly impact energy production and endurance.
  • Injury Prevention: Proper supplementation can strengthen bones, joints, and connective tissues.
  • Immune System Support: Intense training can temporarily suppress immune function, making runners more ill-prone.
  • Hydration and Electrolyte Balance: Long-distance running causes significant fluid and electrolyte loss, which needs to be replenished.

Top 10 Best Supplements For Runners In 2024

1. Iron

Iron is essential for creating hemoglobin and myoglobin – the proteins that help transport oxygen in your blood and muscles. Your endurance and athletic performance can take a severe hit without enough iron.

Who’s at Risk of Deficiency:

Runners, especially women, and vegetarians, are likelylikelier to have low iron levels. Here are the main reasons:

  • Menstruation: Women lose iron during their period.
  • Foot Strike Hemolysis: Running can break down red blood cells from the repeated impact.
  • Sweat Loss: Believe it or not, you also lose iron when you sweat.

Signs You’re Low on Iron:

  • Constant fatigue and weakness
  • Struggling to catch your breath during workouts
  • Lower performance and stamina

How to Get More Iron:

  • From Your Diet: Foods like red meat, poultry, fish, lentils, spinach, and iron-fortified cereals are excellent sources.
  • Supplements: If your diet isn’t enough, iron supplements (like ferrous sulfate or ferrous gluconate) can help—but it’s essential to take them under a doctor’s supervision to avoid iron overload.

2. Vitamin D

Vitamin D is crucial because it helps your body absorb calcium, essential for strong bones. It also plays a significant role in supporting your immune system.

Who’s at Risk of Deficiency:

  • Limited Sun Exposure: If you live in northern areas or it’s winter, you might not get enough sunlight.
  • Darker Skin: People with darker skin don’t produce as much vitamin D from the sun.
  • Training Indoors: Spending a lot of time training inside can limit your sun exposure, too.

What Happens When You’re Low on Vitamin D:

  • A higher risk of stress fractures
  • Muscle weakness
  • A weaker immune system

How to Get More Vitamin D:

  • Sun Exposure: Aim for 10-30 minutes of midday sunlight a few times a week.
  • Dietary Sources: You can also get vitamin D from foods like fatty fish (salmon, mackerel), fortified dairy products, and egg yolks.
  • Supplements: If you’re not getting enough from the sun or food, vitamin D3 (cholecalciferol) is the best form to take as a supplement.

3. Omega-3 Fatty Acids

Omega-3s, especially EPA and DHA, are powerful anti-inflammatory agents that help support heart health and boost brain function.
