Supplements for Runners: A Practical Guide to Endurance, Energy & Recovery
Supplements for Runners
A practical, evidence-based look at what supports endurance, steady energy and recovery on the road and trail.
Running asks a lot of the body — long aerobic efforts, repeated impact, and the recovery needed to do it again tomorrow. A few well-researched supplements can support energy and recovery alongside a solid training plan and diet.
Maca for stamina
A traditional Peruvian root used to support energy and vitality through high-mileage training weeks.
Ashwagandha for recovery
An adaptogen studied for helping the body manage training stress and support recovery (Kaul et al., 2016).
Creatine for intervals
Best known for power, but useful for runners doing sprint work and hill repeats (Kreider et al., 2017).
Lion’s Mane for focus
Long runs are as much mental as physical — Lion’s Mane is studied for nerve and cognitive support.
How they fit a runner’s week
Think of it as: maca for day-to-day energy, ashwagandha in heavy blocks to help you absorb load, creatine if you mix in speed sessions, and lion’s mane for those long-run mental miles. Start with one and build from there.
Will creatine make me gain weight as a runner?
Creatine can cause a small initial water-weight increase in muscle. Many runners still use it for interval/sprint work; if you’re weight-sensitive, trial it in a base-building phase.
When should I take maca?
Most people take it daily, often in the morning. It pairs well with a smoothie or oats.
Are these safe during marathon training?
Generally yes for healthy adults, but training load is individual. If pregnant, breastfeeding, under 18, or on medication, check with a healthcare professional first.
