What is Mag-on Energy Gel?


Mag-on energy gels is an energy gel from Japan that contain 50 mg of highly absorbable water-soluble magnesium, plus valuable sodium, and 120 kcal of energy.

Studies show that the more active you are, the more magnesium you need.

  • Scientists have linked a high level of magnesium in blood to improved muscle performance, which means that you can improve your performance by ensuring an adequate supply of this important mineral.
  • Plus, magnesium appears to lower lactate levels in your blood and exercising without sufficient magnesium will lead to increased oxygen consumption and heart rate.
  • Magnesium also plays a major role in strengthening your immune system. It works similarly to an antioxidant by strengthening your defenses and protecting you from diseases.

What is in Mag-on Energy Gel?


Maltodextrin, fructose, grapefruit juice/citric acid, fragrance, malic acid, magnesium hydroxide, glycine, caffeine

How does it taste like?

When it comes to taste and consistency, Mag-On Energy Gels redefine the experience. If you lean towards a more liquid texture, Mag-On is your ideal choice. Renowned for its distinct tart, fruity flavors, it sets itself apart from typical Western brands like GU and SiS.

During my trial, I found Mag-On's gels to be refreshingly light and pleasantly tart. While Lemon was a tad too sour for my liking, Pink Grapefruit and AO Mikan were a delightful surprise, especially on warm days. In my book, Mag-On earns a solid A for both taste and consistency.

Ready to indulge your taste buds and elevate your performance? Mag-On Energy Gels are your passport to a flavorful and energizing running experience! 🍋🍊

How’s the packaging of Mag-on energy gels?

While the shape aligns with Western market standards, Mag-On's packaging stands out at a longer 12 cm, justifying its generous content of 120 calories and 30g of carbohydrates.

What truly sets Mag-On apart is its unique opening mechanism. Featuring a pre-cut tear at the "lid" of the bottle-shaped sachet, this distinct design, highlighted in a contrasting color, offers an effortless rip. This user-friendly feature ensures a perfect opening, allowing you to easily consume the refreshing watery gel inside.

With Mag-On, convenience meets excellence, making your fueling experience as smooth as your run. Embrace the future of energy gel packaging with Mag-On Energy Gels! 🏃‍♂️✨

Each different flavours come with different motivational quotes:

  • “Well done is better than well said.”
  • “Gray skies are just clouds.”
  • “After a storm comes a calm.”
  • “Winners don’t wait for chances. They take them.”
  • “One finds limits by pushing them.”
  • “Make yourself stronger than your excuses.”

Very inspiring!

How did it perform? Does it work for me?

I put Mag-On Energy Gels to the ultimate test during a 20 km easy run, and here's my firsthand experience:

Taste Test:

  • Lemon: Surprisingly tart, but it did cause some mild throat discomfort.
  • Pink Grapefruit & AO Mikan: Perfect balance of sourness, providing a delightful taste experience.

Performance Insights:

  • A shot of 120 calories, 30g of carbohydrates, and 25g of caffeine every 20 minutes delivered a powerful boost, keeping me energized and focused throughout the run.
  • The sachet's small "lid" piece was hard to manage but created an ideal opening for the watery gel.
  • Three caffeine gels proved excessive for me; opting for non-caffeinated flavors would have been a better choice.
  • Despite the longer packaging, Mag-On Energy Gels proved compact and easily fit into any fuel-carrying gear.


With a potent combination of 120 calories, 30g of carbohydrates, and 50 mg of essential magnesium in every 41g package, they redefine the standards of energy gels.

What sets Mag-On apart is its delightful tart flavor and watery consistency, making it a perfect choice for extended training runs, marathons, and ultra-distance races. Especially in hot and humid conditions, its lightness and fruity goodness make it the ultimate companion for your athletic endeavors.

Yes, the packaging might be slightly larger, but it's a small trade-off for the energy-packed benefits it delivers. Mag-On Energy Gels have proven themselves as exceptional fuel for endurance athletics.

Don't just take our word for it—experience the greatness for yourself! 🏃‍♂️
