Why people are interested

Functions as a cofactor across energy metabolism, neuromuscular signalling and many enzymatic reactions.

Outcome map

One ingredient. Different questions.

Each row answers a separate question; evidence strength can differ by outcome.

01
Filling an intake gap
Magnesium is an essential nutrient, and a supplement can add magnesium when dietary intake is inadequate.
Level A
02
Self-reported sleep
One four-week bisglycinate trial found a small change on a self-reported insomnia scale, with limited certainty and no meaningful replication.
Level C
03
Objective sleep
Bisglycinate-specific evidence does not establish better sleep duration, onset, deep sleep, REM or sleep architecture.
Level D
04
Form superiority
Current comparisons do not establish that bisglycinate is clinically more effective or better tolerated than every other magnesium form.
Level D
05
Healthy aging and lifespan
Human trials do not establish prevention of frailty, dementia or fractures, slower biological aging, or longer life.
Level D

How it may work

Functions as a cofactor across energy metabolism, neuromuscular signalling and many enzymatic reactions.

What people have studied

Magnesium is essential, but an essential nutrient is not automatically a sleep treatment. A 2025 bisglycinate trial found a small four-week change on a self-reported insomnia scale; objective sleep benefit, form superiority and healthy-aging benefit are not established.

What to consider

High supplemental intakes can cause gastrointestinal effects, impaired kidney function increases toxicity risk, and some medicines interact; persistent insomnia or medically complex use needs qualified professional review.

Local pathway

Compound, elemental amount and format require finished-product clearance.
