> A special form of magnesium called magnesium L-threonate may be especially helpful for the brain because it appears to raise brain magnesium levels more effectively than some other forms.

The study that made this claim was performed by the person who patented magnesium L-threonate and sells it at a high price. They go after any company that tries to sell cheap generic versions. The study was in mice and only showed small increases.

Magnesium L-threonate doesn’t get absorbed into your body and go into your brain as a lot of the supplement podcasts and social media posts have been implying. Magnesium supplements like this dissociate into their components in your digestive tract. Magnesium and threonate get absorbed separately. So if magnesium L-threonate has some special properties, it would be because threonate does something to improve absorption or maybe has other effects in the body, but that’s a big if. Remember that the person claiming it works better has been making a lot of money off of that one study.

If you have the cash and don’t mind paying the price then there’s no reason to switch. Many people find that magnesium glycinate, which is cheap, works just as well if not better. Glycine supplementation has been found independently to improve sleep, so taking a magnesium supplement that dissociates into magnesium and glycinate might be helpful in its own way.

Magnesium builds up in the body. Some people are deficient and get strong effects from initially correcting the deficiency. Take high doses for too long and you can start accumulating enough to get into excessive magnesium range, which brings problems. That was previously a rare observation but it’s occurring more as people get into magnesium supplements from podcasts that encourage constant high dose protocols and repeat claims that everyone is severely deficient. Keep the dose moderate.

> And they all wanted to put me on prescription sleeping pills. I said no to that. Sleeping pills can cause dependence, and they often treat the symptom rather than the underlying cause. As a software developer, I am used to finding and fixing the underlying problem instead of relying on the quick fixes these doctors were offering me.

“Sleeping pills” could mean a lot of things. Few doctors will put a patient on long-term hypnotics with high dependence liability like Ambien in the 2020s. Most doctors are hesitant to prescribe them at all in the current environment, and when they do it’s short term. I would be very surprised if you went to multiple doctors who offered to prescribe you something like that as a new patient without a complicated history. Even the people with significant long term insomnia complain about how hard it is to get doctors to prescribe those.

What they usually recommend is weaker medications with somnolence as a side effect, but the effect is weaker and doesn’t target pathways prone to addiction. Trazodone, doxepin, and a few others are common. These are not in the same category as what people think of as “sleeping pills” like Ambien that have higher dependence and addiction liability. They should not be dismissed together as one big category of drugs that are all bad for you.
