Magnesium Glycinate

Most people are deficient. Most magnesium supplements don’t absorb. This one does.

The science

Magnesium is involved in over 300 enzymatic processes — including muscle contraction, protein synthesis, and nervous system regulation. Clinical deficiency is common. Subclinical deficiency is widespread. Standard blood tests measure serum magnesium, which reflects only 1% of total body stores — meaning you can be functionally deficient with normal lab results.

The glycinate form is chelated to glycine — an amino acid with its own calming properties. This is why magnesium glycinate consistently outperforms cheaper forms in sleep and stress trials. Multiple RCTs show improvements in sleep onset, sleep duration, and subjective recovery. If you’re training hard, sleeping poorly, or chronically tense, this is where the evidence points.

How to take it

2 capsules, 30–60 minutes before sleep. Magnesium glycinate’s effect on the nervous system is best used as part of a sleep routine. You can split the dose — 1 capsule with dinner, 1 before bed — if you prefer.

Common questions

What’s the difference between glycinate and oxide?
Absorption. Magnesium oxide — the cheapest and most common form in supermarket supplements — has a bioavailability of around 4%. Magnesium glycinate is chelated to glycine, which dramatically increases uptake. If you’ve taken magnesium before and felt nothing, you were almost certainly taking the wrong form.

Does magnesium glycinate actually improve sleep?
The evidence is consistent. Multiple RCTs show reductions in sleep onset time and improvements in sleep quality, particularly in adults with subclinical deficiency — which is the majority. The glycinate form adds a second mechanism: glycine itself has sleep-promoting effects demonstrated in independent trials.

How long before bed should I take it?
30–60 minutes. At this window, magnesium glycinate supports the transition to sleep without morning grogginess. Some people find it works better split — one capsule with an evening meal and one before bed.

What are the signs of magnesium deficiency?
Poor sleep, muscle cramps or twitching, chronic fatigue, anxiety or irritability, and headaches. Most standard blood tests won’t catch functional deficiency — serum magnesium reflects only a fraction of total body stores. Subclinical deficiency is far more common than the clinical version.

Is it safe for daily long-term use?
Yes. Magnesium is an essential mineral your body uses continuously. Long-term daily supplementation at standard doses (200–400mg elemental) is well-tolerated in healthy adults with no established downside to consistent use.
