Sports Nutrition in an Active City

Milton Keynes has a thriving fitness culture.

How to Choose Safe and Effective Supplements

Start by identifying your goals, whether that is muscle growth, endurance, recovery, weight management or general wellbeing. Protein, creatine and electrolytes are some of the most widely researched supplements, while many other products have weaker evidence. For competitive athletes, products tested under schemes such as Informed Sport reduce the risk of contamination with banned substances.

Read labels carefully, avoid proprietary blends that hide ingredient quantities and be cautious with high-stimulant pre-workout products. If you have a medical condition, are pregnant or take medication, speak to a GP or registered dietitian before starting any supplement.

Sports Nutrition Trends

Plant-based protein is one of the fastest-growing categories, driven by interest in vegan and flexitarian diets. Clean-label products with fewer additives and natural sweeteners are increasingly popular. Ready-to-drink protein shakes and functional snacks reflect the demand for convenience. Personalised nutrition, based on fitness trackers, DNA testing and blood biomarkers, is an emerging trend among data-driven athletes. Sustainability is also influencing packaging, with more brands using recyclable materials and refill options.

Frequently Asked Questions

Do I need supplements to get fit?

No. A balanced diet with enough protein, carbohydrates, healthy fats, fruit and vegetables is the foundation of good performance. Supplements simply add convenience or help fill specific gaps.

Is creatine safe?

Creatine monohydrate is one of the most widely studied supplements and is generally considered safe for healthy adults at recommended doses. Anyone with a medical condition should speak to a doctor first.

What does Informed Sport certification mean?

Informed Sport is a testing programme that checks supplements for substances banned in sport. Certified products are a safer choice for athletes subject to anti-doping testing.
