Why runners need a multivitamin
Running is one of the most metabolically demanding sports. Every kilometer you run consumes essential micronutrients that your body needs to produce energy, transport oxygen, repair muscles and keep your immune system active. The International Society of Sports Nutrition (ISSN) has documented that endurance athletes lose significant amounts of iron, zinc, magnesium and B vitamins through sweat, urine and metabolic effort (ACSM).
The most common deficiencies in runners are vitamin D3 (up to 56% of athletes have insufficient levels according to recent studies), iron (especially in female runners), vitamin B12, zinc and magnesium. A multivitamin does not replace a good diet, but acts as a nutritional insurance that covers the gaps that high-volume training can create.
Key vitamins and minerals for runners
Not all vitamins have the same impact on runner performance. These are the ones you should prioritize when choosing a multivitamin:
- Vitamin D3: Regulates calcium absorption for bone health, improves muscle function and strengthens the immune system. It is the most common deficiency in athletes, especially at high latitudes or when training indoors. Recommended dose: 1000-2000 IU daily.
- Iron: Essential for hemoglobin production, which transports oxygen to muscles. Runners lose iron through sweat, microhematuria (foot impact) and menstruation in women. Look for chelated forms like iron bisglycinate for better absorption.
- Vitamin B12: Involved in red blood cell production and energy metabolism. Its deficiency causes chronic fatigue and anemia. Fundamental for vegetarian or vegan runners.
- Zinc: Key for muscle recovery, protein synthesis and immune function. Runners who train at high volume can lose up to 1mg of zinc per liter of sweat.
- Magnesium: Participates in over 300 enzymatic reactions, including muscle contraction and energy production (ATP). Its deficiency causes cramps, fatigue and poor sleep quality.
- Vitamin C: Antioxidant that protects against oxidative stress from intense exercise. Promotes collagen synthesis, essential for tendons and joints.
- Vitamin E: Another potent antioxidant that protects cell membranes from free radical damage generated during prolonged aerobic exercise.
The 8 best multivitamins for runners
1. Optimum Nutrition Opti-Men - Best for male runners
Best for: male runners at medium-high volume, competition preparation
Optimum Nutrition is synonymous with quality in sports supplementation, and their Opti-Men is the most complete multivitamin on the market for male athletes. The formula includes over 75 active ingredients: 25 essential vitamins and minerals, a free amino acid blend (glutamine, BCAAs), an antioxidant phytochemical complex and digestive enzymes to maximize absorption of all nutrients.
For runners, the generous doses of vitamin D3 (1000 IU), vitamin B12 (100mcg), zinc (15mg) and magnesium (80mg) stand out. The amino acid complex adds an extra layer of recovery that other multis do not offer. With three tablets a day you cover practically all your micronutrient needs, even during high mileage periods. It is the smartest investment for runners who want a complete nutritional insurance.
2. HSN Evovits - Best value for money
Best for: budget-conscious runners, long-term daily use
HSN has proven that quality and affordable pricing can coexist in the same bottle. Evovits is their flagship multivitamin, formulated with 12 vitamins and 10 minerals in highly bioavailable forms. It includes vitamin D3, iron bisglycinate, zinc, magnesium and the complete B complex, everything a runner needs to maintain performance and keep their immune system in shape.
HSN's competitive advantage is the price: at about 14 euros per bottle of 120 capsules (four months of supply with one capsule per day), the monthly cost is just 3.50 euros. It is a Spanish brand with in-house manufacturing and rigorous quality control. If you are looking for a multi that covers the essentials without paying premium international brand prices, Evovits is the smartest choice on the market.
3. Solgar VM-75 - Best pharmaceutical quality
Best for: demanding runners, pharmacy purchase, food intolerances
Solgar has been manufacturing supplements under pharmaceutical standards for over 75 years, and their VM-75 is one of the most respected formulas on the market. What sets Solgar apart is the quality of their mineral forms: all minerals are chelated (bisglycinate, citrate), guaranteeing up to three times higher absorption than the oxide forms used by many cheap competitors.
The formula includes 13 vitamins and 12 minerals at real therapeutic doses, not token amounts. Notable are vitamin D3 at 1000 IU, iron bisglycinate at 10mg, zinc at 15mg and the entire B complex at high doses.

Best for: runners who want antioxidant extras, comprehensive use
NOW Foods is one of the most respected supplement brands in the world, with over 50 years of experience and GMP certification. Their Adam Superior Men's Multi goes beyond basic vitamins and minerals by including CoQ10 (a key coenzyme for cellular energy production), lycopene, grape seed extract and other phytochemicals with antioxidant power.
For runners, this formula is especially interesting because CoQ10 participates directly in the mitochondrial electron transport chain, where the ATP that fuels your muscles is produced. The vitamin D3, B12, zinc and magnesium doses are adequate to cover the needs of a medium-to-high volume runner. With two daily tablets and a price of about 22 euros per bottle, it offers an excellent balance between complete formula and cost.

6. Centrum Performance - Best mainstream pharmacy brand
Best for: runners looking for a well-known pharmacy brand
Centrum is probably the most well-known multivitamin brand in the world, backed by Haleon (formerly GSK Consumer Healthcare).

Centrum's advantage is availability: you can find it at any pharmacy, supermarket or health store. The formula broadly covers basic micronutrient needs with a single daily tablet, simplifying supplementation. The doses are conservative compared to sports brands like Optimum Nutrition, but sufficient for recreational runners at moderate volume who want a basic nutritional insurance.

With 15 vitamins and 10 minerals at sport-level doses (vitamin D3 at 2000 IU, vitamin B12 at 200mcg, iron at 18mg), Alive! Sport is a step above generic multis. The extra electrolyte contribution makes sense for runners who sweat a lot or train in warm climates.

How to choose a multivitamin for running
With so many options on the market, these criteria will help you filter and choose the right multivitamin for your runner profile:
- Training volume: If you run 3-4 days per week at moderate pace, a basic multi like HSN Evovits or Nutravita will suffice. If you train 5-6 days with quality sessions (intervals, tempo, long runs), you need more complete formulas like Opti-Men or Alive! Sport.
- Mineral forms: Prioritize chelated minerals (bisglycinate, citrate, picolinate) over oxide forms. The absorption difference can be 200-300%. Solgar and NOW Foods excel in this regard.
- Real vs token doses: Many cheap multis include vitamins and minerals in doses that do not even reach 50% of the RDA. Check that vitamin D3 is at least 1000 IU, iron at 8-14mg and zinc at 10-15mg.
- Useful extras: CoQ10, digestive enzymes, electrolytes and natural antioxidants provide real value for runners. Added amino acids (as in Opti-Men) are a recovery bonus.
- Stomach tolerance: If you have a sensitive stomach, choose single daily dose formulas with gentle iron forms (bisglycinate instead of sulfate).
When and how to take your multivitamin
The timing and method of taking your multivitamin directly influence its effectiveness:
- With breakfast or your main meal: Always with foods containing healthy fats (avocado, olive oil, nuts). Vitamins A, D, E and K are fat-soluble and need fat for proper absorption.
- Never before training: Iron and some minerals can cause stomach discomfort if you train right after taking them. Leave at least 2 hours between intake and your session.
- Avoid simultaneous coffee and tea: The tannins in coffee and tea reduce iron absorption by up to 60%. If you have coffee at breakfast, take the multi with lunch or wait 30 minutes between coffee and the tablet.
- Separate from calcium: If you take calcium separately, do not take it at the same time as your multi if it contains iron: calcium competes with iron for absorption. Separate them by at least 2 hours.
- Consistency over timing: The most important thing is daily consistency. Choose a time that fits your routine and maintain the habit. Benefits become noticeable after 4-8 weeks of continuous use.
Frequently asked questions
Do runners need to take a multivitamin?
It depends on your diet and training volume. Runners who train more than 4 days per week lose significant micronutrients through sweat (iron, zinc, magnesium) and have higher requirements for B vitamins and vitamin D. If your diet does not cover those needs or you train at high volume, a multivitamin acts as a very useful nutritional insurance. An annual blood test helps you know if you have real deficiencies.
What is the most important vitamin for runners?
Vitamin D3 is probably the most critical. It regulates calcium absorption (bone health), muscle function, the immune system and recovery. ISSN studies show that up to 56% of athletes have insufficient levels, especially at high latitudes or when training indoors. Iron is equally crucial, especially for female runners, due to its role in oxygen transport to muscles.
When is the best time to take a multivitamin?
Ideally take it with breakfast or your main meal, always with foods containing healthy fats. Vitamins A, D, E and K are fat-soluble and need fat for absorption. Avoid taking it right before training as it can cause stomach discomfort. If your multivitamin contains iron, do not take it with coffee or tea because tannins reduce its absorption by up to 60%.
Can you combine a multivitamin with other running supplements?
Yes, but with precautions. A multivitamin is compatible with whey protein, creatine and omega-3. However, avoid combining it with individual supplements of the same vitamins already in the multi to avoid exceeding recommended daily doses. For example, if your multi already has 1000 IU of vitamin D3, do not add another vitamin D supplement without consulting your doctor. Iron and calcium compete for absorption, so separate them by at least 2 hours.
Is there a difference between multivitamins for male and female runners?
Yes, there are important differences. Female runners need more iron (especially premenopausal women, who lose iron through menstruation in addition to sweat), more folic acid and more calcium. Men typically need more zinc and magnesium. That is why specific formulas like Opti-Men and Opti-Women from Optimum Nutrition exist. If you choose a unisex multivitamin, make sure the iron and zinc doses match your profile.
