Outcome map
One ingredient. Different questions.
Each row answers a separate question; evidence strength can differ by outcome.
- 01Level A
Filling an intake gap
Magnesium is an essential nutrient, and a supplement can add magnesium when dietary intake is inadequate.
- 02Level C
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.
- 03Level D
Objective sleep
Bisglycinate-specific evidence does not establish better sleep duration, onset, deep sleep, REM or sleep architecture.
- 04Level D
Form superiority
Current comparisons do not establish that bisglycinate is clinically more effective or better tolerated than every other magnesium form.
- 05Level D
Healthy aging and lifespan
Human trials do not establish prevention of frailty, dementia or fractures, slower biological aging, or longer life.
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.
