magnesium glycinate
Reddit take
AI summary of the Reddit excerpts below — not a quote
Magnesium glycinate is a highly popular supplement on Reddit, primarily valued for its high bioavailability and its effectiveness in aiding sleep and reducing muscle cramps. While it is frequently recommended as a foundational supplement alongside Vitamin D and Omega-3, it is notable for causing paradoxical reactions in a subset of users, where instead of calming the nervous system, it triggers anxiety or insomnia.
Pros
- Highly effective for eliminating nocturnal muscle and calf cramps.
- Improves sleep quality, with users reporting feeling more well-rested upon waking.
- Superior absorption and bioavailability compared to magnesium oxide.
- Helps reduce physical tension, such as jaw clenching and general evening stress.
Cons
- Can cause paradoxical anxiety, racing heart, or restlessness in sensitive individuals.
- May lead to severe insomnia for some, preventing sleep until early morning hours.
- Potential for headaches, which users often attribute to the glycine component.
Caveats
- Reactions to the glycine carrier are highly individual; what is sedating for one person may be stimulating for another.
- Some users report no noticeable effects even after consistent use for a week or more.
- Dosages mentioned by users vary widely, from 160mg to 800mg daily.
Best for
- Individuals seeking a magnesium form that is easy on the stomach with high absorption.
- People suffering from chronic nighttime leg cramps.
- Those looking for a natural sleep aid to improve restfulness.
Avoid if
- You have a known sensitivity to glycine.
- You experience increased heart rate or 'brain fog' after taking amino acid-bound minerals.
- Initial doses result in increased anxiety or disrupted sleep patterns.
This summary uses balanced time weighting with about a 6-month half-life. The evidence is based on mentions from 2025 with a median age of approximately 310 days; while magnesium is a stable product, users should consider this a snapshot of community sentiment from that period.

What redditors said (10 of 134)
I wanted to mention that inositol, which I take with magnesium glycinate and theanine, resolved my insomnia which had been going on for 11 months.
The only ones I recommend to others (despite having a large *expensive pee* stack myself) are Vit D and Magnesium (glycinate)
Can confirm, even without sleep issues, magnesium glycinate (or bisglycinate, same thing) makes me wake up feeling more well rested.
I recently tried to make the switch from oxide to glycinate (I'd also heard of how it's easier for the body to absorb) and, unfortunately, the glycinate kept me up with HORRIBLE anxiety...
Mag glycinate puts most people to sleep
I started taking magnesium glycinate for tight pelvic floor (200mg). Not only has it helped my pelvic muscles, it’s greatly reduced my anxiety.
glycinate is the good stuff but probably makes up like 20-30% of that mix at most. Next time just grab straight glycinate, it's worth the extra few bucks
Glycinate is a very good one that has good absorption
Magnesium glycinate is better absorbed and calming; oxide less so and can cause digestive upset.
next time get straight glycinate, way better absorption
