Real Results, Real People

"It's important to focus on ensuring optimum health to handle the training loads, and as I'm pushing 40 it's doubly important. Magnesium is such an important supplement to maintain bone density as we age, help with sleep, mood regulation and overall energy levels, that it's something I always supplement. Protein Rebel's magnesium trumps other options by being from natural sources, unflavoured and mixes well in anything so that I can take it with juice or in an evening cup of tea."

"Power Up is far more enjoyable than my previous supplement as it mixes so easily without the clumps. I mix a spoon into a glass of water an hour or so before bed for a refreshing drink with a hint of citrus and the best night's sleep!"

SCIENCE
The number and quality of research into the positive affect’s magnesium has on runners is growing fast. We have summarised them in the following blog article:
• Document: How to use magnesium to improve your running
• Link: https://proteinrebel.com/blogs/blog/how-to-use-magnesium-to-improve-your-running
• Key Finding: The blog emphasizes that magnesium is a crucial mineral for runners, as it is lost through sweat and plays a vital role in over 300 bodily functions. It highlights that many people are deficient, and runners may need 10-20% more magnesium daily to account for losses during exercise.
Benefits for Performance and Recovery
• Key Finding: Magnesium is said to improve performance by boosting energy levels, preventing lactic acid build up, and increasing muscle power. For recovery, it helps to speed up muscle repair, reduce soreness, and support better sleep, which is essential for the body's natural healing process. The article suggests taking a highly bioavailable form, like magnesium citrate, before bed for optimal absorption.
We have searched the internet and spoken to academics about the positive effects of magnesium for runners. The following 5 research papers provide more details:

3. Boost Your Recovery: Magnesium May Reduce Muscle Soreness in Just 7 Days
• Document: One week of magnesium supplementation lowers IL-6, muscle soreness and increases post-exercise blood glucose in response to downhill running
• Link: https://pubmed.ncbi.nlm.nih.gov/31624951/
• Key Finding: This study's abstract concludes that magnesium supplementation reduced muscle soreness after strenuous exercise. The methodology involved providing a supplement daily for 7 days prior to a running time trial.
5. Stop Cramps on the Trail: Severe Cramps Reduced by More Than Half
• Document: A Magnesium-Rich Electrolyte Hydration Mix Reduces Exercise Associated Muscle Cramps in Half-Marathon Runners: Direct Original Research
