Can you tell me about different forms of magnesium?

Here's a summary of the different forms of magnesium mentioned by Andrew Huberman and their typical uses:

1. Magnesium Threonate: Can support cognitive function and promote the transition into sleep. It has the ability to cross the blood-brain barrier, which makes it helpful for enhancing the depth and onset of sleep and possibly neuroprotection in the brain. This form should be taken about 30 to 60 minutes before bedtime 1 2 3.

2. Magnesium Bisglycinate: An alternative to magnesium threonate, it does not have known cognitive enhancing effects but seems comparable to threonate for promoting transition into and depth of sleep 1 4.

3. Magnesium Malate: Typically used for muscle recovery and restoration of magnesium stores in the periphery as opposed to the brain, making it more suitable for those looking to alleviate muscle soreness rather than induce sleepiness 2.

4. Magnesium Citrate: Known for its laxative effect, this form of magnesium is less appropriate for sleep induction and more often used for gastrointestinal regulation 2 5.

It is important to approach any new supplement with caution, especially magnesium, as it can be involved in heart rhythm and other significant bodily functions. Always consult with a healthcare provider before beginning any new supplementation regimen to ensure safety and proper use 2.
