myBrainCo difference
Multi-Mag Hydration is a multi-action performance formula designed to support key physiological processes involved in physical activity and recovery. It combines four bioavailable forms of magnesium with HMB, electrolytes, taurine, and carnitine, each selected for their complementary roles in muscle function, energy metabolism, and hydration balance. Together, these ingredients work synergistically to support training demands, endurance, and recovery as part of an active lifestyle.
Each serving delivers a total of 365mg of elemental magnesium from four complementary forms: magnesium orotate, aspartate, citrate, and ma. Magnesium orotate and aspartate are commonly used to support cellular energy production and metabolic pathways, while magnesium ma plays a role in ATP production and muscle energy metabolism through its involvement in the Krebs cycle. Magnesium citrate contributes to normal muscle function and electrolyte balance, supporting neuromuscular activity during periods of physical demand. Providing magnesium in multiple bioavailable forms supports efficient absorption and utilisation to meet the demands of training, recovery, and active lifestyles.
Each serving provides a clinically relevant dose of HMB (3 g as calcium HMB), a metabolite of the amino acid leucine involved in muscle protein metabolism. HMB is commonly used to support normal muscle function and recovery, and to help limit muscle protein breakdown during periods of increased training load or physical stress. By supporting the balance between muscle protein breakdown and synthesis, HMB complements resistance training, active lifestyles, and the maintenance of muscle function and mass with age.
This formula includes a balanced blend of key electrolytes to support fluid balance, hydration status, and neuromuscular function during physical activity. Electrolytes such as sodium and potassium play an important role in maintaining normal muscle contraction, nerve signalling, and fluid distribution, particularly when losses increase through sweat. Taurine contributes to cellular hydration and electrolyte regulation, supporting neuromuscular function and hydration balance during training and active lifestyles.
This formula includes L-carnitine tartrate and taurine, selected for their roles in cellular energy metabolism and endurance support. L-carnitine contributes to mitochondrial energy production by supporting the transport of fatty acids into cells for energy use, while taurine supports neuromuscular function and cellular resilience during periods of physical demand. Together, these ingredients support efficient energy utilisation and endurance as part of training, exercise, and active lifestyles.

Frequently asked questions
Multi-Mag Hydration is designed to support muscle function, hydration, and energy metabolism during physical activity and active lifestyles. It provides 365 mg of elemental magnesium from four complementary forms, alongside electrolytes to support fluid balance, a clinically relevant dose of HMB to support muscle protein metabolism and recovery, and taurine and carnitine to support cellular energy utilisation and endurance. Together, these ingredients help support training demands, recovery, and the maintenance of normal muscle function as we age.
Multi-Mag Hydration can be taken at the time that best suits your routine and activity level. It’s commonly used before training to support hydration and muscle function, during exercise to help maintain electrolyte balance, or after training to support recovery and replenishment following sweat loss. It can also be taken at any time of day on non-training days to support daily magnesium intake, hydration, and normal muscle function.
If you are pregnant or breastfeeding, we recommend consulting your healthcare professional before using Multi-Mag Hydration. While the ingredients in Multi-Mag Hydration are commonly used to support hydration and muscle function, nutritional needs can vary during pregnancy, and individual circumstances should always be considered. A qualified healthcare practitioner can help determine whether this product is appropriate for you and advise on suitable intake during pregnancy.

Multi-Mag Hydration is suitable for long-term use when taken as directed.
The ingredients are included at levels designed to support normal muscle function, hydration, and energy metabolism as part of an active lifestyle. As with any supplement, individual needs can vary, so if you plan to use Multi-Mag Hydration long term, or have a medical condition or take medications, it’s best to consult your healthcare professional for personalised advice.
If you are taking medications, it’s best to consult your healthcare professional before using Multi-Mag Hydration. Magnesium and other electrolytes can interact with certain medications, including some antibiotics and thyroid medications, by affecting absorption. A qualified practitioner can advise whether Multi-Mag Hydration is appropriate for you and recommend how to space it from any medications if needed.
