Dr. Berg Magnesium Glycinate Review: A Sleep Supplement That Skips the Filler
Key Features
Glycinate Form
Uses magnesium glycinate, one of the most bioavailable and gut-friendly forms of magnesium, bound to the amino acid glycine for better absorption.
Sleep Support
Glycine plays a role in calming the nervous system. Many users report falling asleep faster and staying asleep longer after consistent use.
Muscle Relaxation
Helps ease muscle cramps and tension, particularly in the legs and back. A useful addition to any nighttime recovery routine.
Clean Formula
Free from synthetic fillers, artificial flavors, and common allergens. Each capsule delivers 400mg of elemental magnesium from glycinate.
Our Experience
We tested Dr. Berg’s Magnesium Glycinate over a four-week stretch, taking two capsules about 30 minutes before bed each night. The first thing worth noting is the capsule size — they’re on the larger side, but manageable with a full glass of water.
By the end of the first week, the difference in sleep onset was noticeable. Falling asleep took roughly 15 minutes less on average compared to the baseline week without supplementation. The deeper change showed up around week two: fewer middle-of-the-night wake-ups and noticeably less leg restlessness after evening workouts.
Stomach tolerance was solid throughout the trial. Some magnesium forms cause digestive issues, but glycinate stayed gentle even at the full recommended dose. Morning grogginess was never a problem — if anything, waking up felt a bit smoother than usual. For the price point, this formula delivers clean magnesium in a form your body can actually use.
