### Top Supplements & Fuel for Runners in the UK
- Vitamin D3 - Why it matters: Essential for bone strength, muscle function, and immunity. In the UK, the NHS recommends considering a daily supplement during the autumn and winter months (October to March) due to limited sunlight. - Omega-3 (Fish Oil) - Why it matters: Helps reduce post-run joint stiffness, inflammation, and aids recovery. Dedicated endurance options like RunnerVits High-Strength Omega-3 offer clean, batch-tested support. - Magnesium (Citrate or Bisglycinate) - Why it matters: Supports muscle relaxation, nervous system function, and sleep quality, which is critical when mileage increases. - Electrolytes & Hydration Formulas - Why it matters: Replenishes vital salts (sodium, potassium, magnesium) lost through sweat on long or hot runs. Tailored options include Precision Hydration (via sweat testing) or quick-dissolving tabs from OTE Sports. - Carbohydrate Gels & Energy Drinks - Why it matters: Serves as the primary fuel source for sessions lasting over 60-90 minutes. UK brands like OTE Sports Marathon Nutrition provide high-carb energy gels and drinks designed by runners. - Protein Powder / Essential Amino Acids (EAAs) - Why it matters: Aids in muscle repair and prevents tissue breakdown after heavy long-runs or speedwork. Brands like Myprotein UK offer targeted whey and EAA blends.
