Marine Magnesium Citrate Powder - Easy Mix, 40 Servings - Made for Runners, Cyclists & Endurance - Gentle on The Stomach, Promotes Sleep, Prevents Cramp - Power Up, Magnesium Powder by Protein Rebel

## Features

- HIGHEST QUALITY MAGNESIUM SUPPLEMENTS FOR RUNNERS:- Protein Rebel’s Power Up high strength magnesium supplement is designed for runners by runners. Unlike the vast majority of magnesium powder supplements, it contains 100% pure magnesium carefully harvested in small amounts from the Irish Sea, and nothing else! Marine magnesium is one of the most essential and reliable nutrients for runners and other endurance athletes, boosting energy and endurance, preventing cramp, aiding in hydration, and most importantly - encouraging a good night’s sleep!
- CONVENIENT SERVING SIZE & MIXABILITY:- Each sustainable metal tin contains 40 servings of 2.5g (one teaspoon). Each serving contains 275mg of elemental magnesium. This provides incredible value, with one tin lasting over a month when used daily. The powder blends easily and immediately with water, leaving no unpleasant lumps unlike lower quality competitors. While our magnesium powder is completely pure and unflavoured, it does come with the slight citrus taste of natural magnesium.
- ESSENTIAL FOR ENDURANCE ATHLETES:- Magnesium is arguably the single most important of all running electrolytes and minerals supplements. After food and water, it is the next thing endurance athletes need to be prioritising. It supports energy production, regulates muscle and nerve function, and aids in recovery. It can help prevent muscle cramps, reduce fatigue, and improve overall performance. Magnesium also plays a role in bone health and blood sugar regulation and helps get a good night’s sleep.
- VERSATILE & EASY TO USE:- Can be easily mixed into water, juices, or smoothies to suit your preferences. It dissolves easily in liquid and leaves no sludge at the bottom. Beyond helping you on your run, Power Up is also highly effective for those who need magnesium for sleep, as a brain fog supplement, as anti muscle cramp supplements and more due to its high purity. Another common use is magnesium for restless legs which may be experienced by runners in downtime.
- COMPACT & SUSTAINABLE:- The 100g tin is lightweight, portable and 100% recyclable, fitting onto any kitchen or work surface making it easy to incorporate into your daily routine. It can even be reused or repurposed as a storage tin. We are so proud of our UK made marine magnesium powder and have put so much work into making it blend better than other competing products that if you aren’t 100% happy within 30 days, we will replace or refund with no questions asked. Power Up your running now!
