Glycine and Magnesium
A classic sleep stack: glycine lowers core body temperature while magnesium glycinate relaxes muscles and calms the nervous system.
Glycine
A calming amino acid for sleep, collagen, and metabolic health.
Magnesium
A master mineral involved in 300+ enzyme reactions.
Great to combine
These two are frequently stacked together; they complement each other and are commonly taken at the same time.
How to take them
Glycine
- Dose
- 3 g before bed for sleep; up to 10 g/day for collagen support
- Timing
- 30–60 minutes before bed for sleep; with meals for collagen/metabolic goals
Magnesium
- Dose
- 200–400 mg elemental magnesium per day
- Timing
- Evening for sleep support; with food to reduce GI upset
Frequently asked
Can you take Glycine and Magnesium together?
Yes, they are commonly taken together. A classic sleep stack: glycine lowers core body temperature while magnesium glycinate relaxes muscles and calms the nervous system.
What's the best time to take Glycine and Magnesium?
Around the same time works well. Glycine: 30–60 minutes before bed for sleep; with meals for collagen/metabolic goals. Magnesium: Evening for sleep support; with food to reduce GI upset.
How do Glycine and Magnesium interact?
Synergy: Work better together than alone. A classic sleep stack: glycine lowers core body temperature while magnesium glycinate relaxes muscles and calms the nervous system.
Related pairings
Glycine + NAC
NAC provides cysteine while glycine provides another rate-limiting precursor; together they are more effective at raising glutathione than either alone (GlyNAC protocol).
Creatine + Glycine
Glycine is one of the three amino acids the body uses to synthesise creatine endogenously.
L-Glutamine + Glycine
Both are conditionally essential under stress and support gut and immune function through complementary pathways.
Glycine + L-Tryptophan
Glycine (inhibitory) and tryptophan-derived serotonin/melatonin work through complementary pathways to support sleep.
