Mag-Tab®SR is magnesium lactate paired with a sustained-release formulation. Magnesium lactate is a highly absorbable form of magnesium, easy on the stomach, and known to be highly bioavailable. This form of magnesium, combined with our sustained-release technology, enables Mag-Tab®SR to deliver magnesium lactate gradually to the body, maintaining steady magnesium levels around the clock. The body utilizes and circulates this form of magnesium more efficiently compared to immediate-release forms. This is an unparalleled formulation, as most magnesium supplements are immediate-release capsules or uncoated tablets.

Magnesium deficiency can induce symptoms and increase susceptibility to stress, and acute and chronic stress can trigger magnesium deficiency. This is known as the vicious circle, describing the bi-directional relationship between magnesium levels and stress.

When you’re under physical or emotional stress, your body releases stress hormones like adrenaline and cortisol. On the other hand, Magnesium acts as a natural nervous system relaxant. When magnesium levels are low, the stress response stays “on” longer. You may feel more anxious, restless, or fatigued. Sleep quality often declines, worsening the cycle.

How to break the cycle and restore balance? Eat a magnesium-rich diet, practice mindfulness, breathing, or yoga. But most of all, supplement with Mag-Tab®SR.

Low magnesium levels are a common and serious problem for those with Chronic Alcohol Use Disorder. Individuals with alcohol use disorder often have a poor and unbalanced diet. They may prioritize alcohol consumption over eating nutritious meals, which are the main source of magnesium. Alcohol provides "empty calories" that fill the body without providing essential vitamins and minerals, including magnesium. This reduced dietary intake further contributes to the deficiency.
