Magnesium is a vital mineral involved in over 300 biochemical reactions in the body, yet many adults fail to meet their daily magnesium needs through diet alone. Supplementing with magnesium can help, but with various forms available, it’s essential to choose the right one for your health goals.
Two of the most popular options are Magnesium Glycinate and Magnesium Citrate. If you’re unsure which one is right for you—whether you’re looking to improve sleep, manage stress, or relieve constipation—this magnesium glycinate vs citrate comparison guide will help you decide. Let's explore!
Magnesium Glycinate vs. Magnesium Citrate: An In-depth Comparison
Factor | Magnesium Glycinate | Magnesium Citrate |

Cost | Higher cost | More affordable |
Magnesium Glycinate: Benefits and Best Uses
Magnesium Glycinate is formed by combining magnesium and glycine which forms the most bioavailable compound. Being highly bioavailable, it can be well-absorbed by the body, making it most effective for supplementation. It consists of around 14.1% of elemental magnesium.
Key Benefits of Magnesium Glycinate:
Promotes Relaxation and Sleep: The calming effects of magnesium and glycine together can relax the muscles and central nervous system, enhancing sleep quality.
Supports Muscle & Nerve Health: By improving mineral absorption, alleviating muscle function, promoting relaxation, and preventing nerve discomfort, it supports nerve and muscle function.
Eases Digestive Issues: As this form of magnesium is gentle on the stomach and less likely to contribute to indigestion, it is an ideal option for people with chronic digestive issues or sensitive stomachs.
Reduces Stress & Boosts Mood: Replenishes lost magnesium levels which reduces cortisol levels (stress hormones) and stabilizes mood.
When to Choose Magnesium Glycinate?
- If you are struggling with insomnia or poor sleep quality.
- If you are experiencing chronic stress or anxiety.
- If you need a gentle option for sensitive stomachs.

Magnesium Citrate: Benefits and Best Uses
Magnesium citrate is another popular supplement with a combination of magnesium and citric acid that is highly bioavailable, meaning it can be easily absorbed by the body. This supplement consists of around 16% elemental magnesium, making it most suitable for those who get inadequate amounts of this mineral from their diet.
Key Benefits of Magnesium Citrate:
Relieves Constipation: According to MedlinePlus, by drawing out water into the intestine, magnesium citrate softens the stool and eases bowel movements.
Improves Bone Health: Citrate promotes effective calcium absorption which helps improve bone strength and density.
Treats Magnesium Deficiency: Due to its higher bioavailability (easily absorbed), magnesium citrate can increase magnesium levels.
Balances Electrolytes: Maintains electrolyte balance that is essential for energy production and proper hydration.
When to Choose Magnesium Citrate?
- If you are experiencing constipation or irregular bowel movements.
- You are looking for a budget-friendly magnesium supplement.
- You need a quick magnesium boost.
