Nutrition for Energy & Performance

Introduction

What you eat has a direct impact on how you feel and perform — whether at work, in the gym, or during day-to-day activities. In Ireland, low energy is one of the most common complaints people mention to GPs, and nutrient deficiencies are often part of the reason.

This article looks at how nutrition fuels energy and performance, and which nutrients are essential to keep your body working at its best.

1. Energy Starts with Your Diet

Carbohydrates, proteins, and fats are your body’s main energy sources. If any are lacking, your body may struggle to perform daily tasks, let alone intense exercise.

2. The Role of Vitamins & Minerals

• B Vitamins (especially B12) help convert food into usable energy.

• Iron carries oxygen in the blood to your muscles and organs.

• Magnesium supports muscle contraction and relaxation.

• Vitamin D plays a role in muscle function and immunity.

3. Hydration Matters

Even mild dehydration can cause fatigue, poor concentration, and slower recovery times.

4. Nutrition & Recovery

Nutrients like protein, omega-3 fatty acids, and antioxidants help repair muscle tissue after exercise and reduce inflammation.

When to Get Tested

If you’re feeling constantly tired, struggling to focus, or not recovering well from exercise, a Vitamin or Nutrition blood test can highlight any deficiencies.

At PURE Pharmacy, your blood draw will be carried out by a trained phlebotomist in a private consultation room, with results in 3 business days or less.
