Since you're starting fresh, a base of these 7 supplements is a sensible place to begin for your goals.
Morning: Iron, Protein, Vitamin C, Creatine and Vitamin D. Midday: Electrolytes. Evening: Magnesium.
Why it's included: You asked to include Electrolytes. Considered for heavy sweating or hot conditions.
Possible benefits
No product matched these filters — try relaxing them.
Why it's included: You asked to include Iron. Considered by those prone to low iron; confirm need via testing.
Possible benefits
No product matched these filters — try relaxing them.
Why it's included: You asked to include Protein. Considered when it's hard to reach protein targets through meals, when training a lot, or when meals are irregular.
Possible benefits
No product matched these filters — try relaxing them.
Why it's included: You asked to include Magnesium. Considered by people whose diet may fall short, or who are very active.
Possible benefits
No product matched these filters — try relaxing them.
Why it's included: A good pairing with Iron. Vitamin C helps the body absorb non-heme iron (the form in plant foods) — a classic pairing for anyone minding their iron.
Possible benefits
No product matched these filters — try relaxing them.
Why it's included: A good pairing with Protein. Protein supplies muscle's building blocks and creatine supports high-intensity effort — the staple stack for people who lift.
Possible benefits
No product matched these filters — try relaxing them.
Why it's included: A good pairing with Magnesium. Magnesium is needed by enzymes involved in how the body activates and uses vitamin D — a reason people taking D often mind their magnesium too.

Morning, with vitamin C; space apart from tea/coffee.
After exercise or at breakfast, to top up protein.
After breakfast; take with iron if you supplement iron.
A small amount at a set time daily — consistency matters more than timing.
After breakfast with some dietary fat for absorption.
Around and during exercise for hydration.
In the evening, for relaxation and recovery.
Magnesium is needed by enzymes involved in how the body activates and uses vitamin D — a reason people taking D often mind their magnesium too.
Why it works: The steps that convert vitamin D into its active form and put it to work rely on magnesium-dependent enzymes. Magnesium is also a mineral many people fall short on, so some pair it with D as part of the base. Many also take magnesium in the evening for a sense of calm.
Vitamin C helps the body absorb non-heme iron (the form in plant foods) — a classic pairing for anyone minding their iron.
Why it works: Non-heme iron is harder to absorb, but vitamin C helps convert it into a more absorbable form. That's why people on plant-forward diets, or anyone prone to low iron, often take vitamin C alongside iron.
Protein supplies muscle's building blocks and creatine supports high-intensity effort — the staple stack for people who lift.
Why it works: Adequate protein supports maintaining and building muscle alongside training, while creatine monohydrate is one of the best-studied aids for short, high-intensity effort. Their roles differ, so they're used together rather than as substitutes.
For people who sweat a lot, magnesium and electrolytes are often discussed together as part of hydration and mineral balance.
Why it works: Sweating from exercise or heat loses electrolytes like sodium and potassium — and some magnesium too. That's why endurance athletes and people in hot conditions sometimes add magnesium alongside an electrolyte drink.

Our AI assistant can explain why this combination, how to take it, and more.
Electrolytes lost through sweat, and iron, which some endurance athletes watch. Iron is also one to avoid overdoing, so if you're unsure, checking levels with a healthcare provider is safest.
Hydration and electrolytes around the run, plus energy and protein from food, are the basics. Treat supplements as a top-up and adjust to your training load and how you feel.
Build mileage gradually, prevent injury with rest days and proper shoes, and keep carbohydrate energy and fluids topped up. Supplements matter mainly for electrolytes in long or hot runs, and iron when a test confirms you are low.
Choose one relevant outcome before starting, record a baseline, and review it at the interval in the guide. Do not use a supplement feeling as a diagnosis.
Take iron only when a test confirms deficiency and under guidance; taken otherwise it can harm. Over-drinking water on long efforts risks hyponatraemia. Menstrual disturbance, stress fractures or extreme fatigue can signal under-fuelling (RED-S) and warrant care. Athletes should check anti-doping contamination risk and their sport's rules.
