Support digestive comfort with alkalising magnesium Each capsule provides 144mg of elemental magnesium from magnesium hydroxide, one of the highest elemental magnesium doses per capsule in the range. Magnesium hydroxide is traditionally used as an antacid and gentle osmotic laxative, and in supplement form it serves a dual purpose: providing meaningful systemic magnesium alongside gastrointestinal benefits for those who experience acid reflux, heartburn or constipation.When magnesium hydroxide encounters stomach acid, it reacts to form magnesium chloride and water, neutralising excess acid in the process. The magnesium chloride produced is then available for absorption. Any unabsorbed magnesium hydroxide passes to the intestines where it draws water by osmosis, softening stool and supporting regular bowel movements. This dual action makes it a practical choice for older adults or anyone who needs magnesium supplementation alongside digestive comfort. The vegetarian capsule shell is hydroxypropyl methylcellulose. Key benefits: Supports digestive comfort and a settled stomach Regular bowels and comfortable digestion Gentle alkalising effect on the gut Each capsule contains: %NRV* Magnesium 144 mg 38% † Nutrient Reference Value (NRV*) not established Magnesium Hydroxide, Hydroxypropyl Methylcellulose (capsule). Magnesium Hydroxide, Hydroxypropyl Methylcellulose (capsule). Directions for use:Take 1 capsule per day with food.Taking with a meal ensures optimal conditions for the conversion to absorbable magnesium chloride and provides the acid neutralising benefit at the time it is most useful. If using specifically for constipation support, the capsule can be taken in the evening to encourage a morning bowel movement.For those primarily seeking magnesium for muscle relaxation, sleep or stress without the gastrointestinal effects, Magnesium Bisglycinate or Magnesium Malate may be more appropriate choices. Magnesium Hydroxide is the best fit when antacid support and gentle bowel regulation are also desired alongside systemic magnesium replenishment.
