Short answer
Magnesium contributes to the reduction of tiredness and fatigue and to normal functioning of the nervous system and muscles. Bisglycinate is a chelated form that many people find gentle on the stomach—a practical choice in the evening.
Key takeaways
- Magnesium contributes to reduced tiredness and normal energy-yielding metabolism.
- It contributes to normal nervous-system and muscle function.
- Bisglycinate avoids the frequent laxative downside of magnesium oxide.
Why the form matters
Not all magnesium salts behave the same. Oxide is often poorly absorbed and can trigger digestive upset. Bisglycinate is chelated, generally well absorbed and well tolerated, which makes it a sensible pick for everyday use.
That is the form we carry in WeightWorld Magnesium Bisglycinate on HA Nutrition.
Sleep, stress and cramps
Magnesium contributes to normal psychological function and normal functioning of the nervous system, which is why people often use it during stressful periods or before bed.
It also contributes to normal muscle function—hence its popularity for night cramps. Taking it in the evening with food is usually the most practical routine.
