| Description | Cofactor for 300+ enzymes, including those that activate vitamin D and produce ATP. Low intake is common in Western diets. | One of the better-absorbed, inexpensive forms: in a randomized comparison it raised magnesium levels more than amino-acid chelate or oxide. Its laxative effect is useful for constipation but limits the dose some people tolerate. |
| Timing note | Evening or bedtime is popular because some people find it relaxing. Consistency matters more than timing. | Any time of day, with a glass of water. Larger doses loosen stools — it's also sold as a laxative. |

If you take both
Usually unnecessary — both supply magnesium, and the amounts add up.
Pick one form, or add up the elemental magnesium on both labels.
