# Best supplements for runners in Britain 🇬🇧

For most runners in the UK, the best supplements are those that support energy, recovery, bone health and endurance\. You don't need a cupboard full of powders and pills - a few targeted supplements can be more useful, depending on your mileage, diet and race goals.

The key principle is to supplement a genuine nutritional need rather than automatically taking everything marketed to runners.

## The 6 supplements worth considering

!ZERO | Electrolyte Drink Tablets | Sugar Free Hydration | HIGH5

1\. Electrolytes - for long runs and hot weather

(Useful for endurance)

Replace sodium lost through sweat, particularly on long runs, in warm weather or if you sweat heavily. They are not essential for every short, easy run.

UK option: HIGH5 ZERO Hydration\. Product listing: View price and availability\.

---

![Holland Barrett Vitamin D 1000 IU - Immune Support - McGrocer](

2\. Vitamin D3 - for bone and muscle health

(Particularly relevant in Britain)

The NHS advises adults to consider 10 micrograms (400 IU) daily during autumn and winter. Year-round supplementation may be appropriate if you get little sun exposure.

Example: Holland & Barrett Vitamin D3 1000 IU\. View product\. Note that 1,000 IU is 25 micrograms, above the standard UK daily recommendation.

!Optimum Nutrition Gold Standard Whey Powder | Holland & Barrett

3\. Protein powder - for recovery

Convenient if your diet doesn't provide enough protein, especially when combining running with strength training. A shake is optional if you already eat enough protein-rich foods.

Example: Optimum Nutrition Gold Standard Whey\. View product\.

![SIS GO Isotonic Gel Variety pack - THE FUELLING HUB](

4\. Carbohydrate gels - for long-distance running

Particularly useful for longer training sessions and races, often around 90 minutes or more. They supply quick energy and help you maintain pace. Practise taking them during training.

Example: SiS GO Energy Gel\. View product\.

---

!Beet It Beetroot Juice Shots for Endurance | The Feed

5\. Beetroot nitrate - for potential performance gains

May modestly improve endurance or exercise efficiency in some runners. Benefits vary, and products differ in their actual nitrate content. A concentrated shot is more practical than an ordinary beetroot capsule with an unverified nitrate dose.

Example: Amacx Beet Shot\. View product\.

---

!MaxiMuscle Caffeine Tablets 175g

6\. Caffeine - for hard sessions and races

One of the better-supported performance aids for endurance exercise. It may reduce perceived effort, but can cause jitters, stomach problems, palpitations or poor sleep. Coffee may be sufficient; tablets aren't necessary.

Best used selectively before key sessions, not automatically before every run.

These choices reflect guidance from the British Nutrition Foundation and the International Olympic Committee: the best-supported performance aids include caffeine and nitrate, while sports foods can help meet energy needs and vitamin or mineral supplements are most valuable when they address a real need. www.nutrition.org.ukpmc.ncbi.nlm.nih.gov

## What about iron and magnesium?

- Iron\: Don't take it just because you run. Low iron can contribute to fatigue and reduced performance, but unnecessary iron can be harmful. If you're unusually tired, breathless or struggling to recover, ask your GP whether a blood count and ferritin test are appropriate. - Magnesium\: Most runners don't need a supplement if their diet is adequate. Evidence that extra magnesium prevents ordinary exercise-related cramps is limited. - Creatine monohydrate\: Worth considering if you do regular strength training, sprint intervals or repeated high-intensity efforts. It is less directly useful for pure endurance running and can increase body weight through water retention.

The NHS and sports-nutrition guidance are good starting points for deciding whether you need supplements at all. www.nutrition.org.ukpmc.ncbi.nlm.nih.govdoi.org

## Let me narrow this down for you

The best combination depends on the type of running you do.

1\. What distance do you mainly run?

5K / 10K

Half marathon / marathon

Ultra / trail running

General fitness / parkrun

---

2\. What's your main goal?

Run faster and improve endurance

Recover better and feel less tired

Prevent injuries and stay healthy

Weight management

---

3\. What's your usual diet?

Mixed diet

Vegetarian

Vegan

---

4\. Monthly budget

Under £20

£20-£40

£40+
