Solution of Magnesium by Allergy Research Group is a liquid magnesium supplement designed for individuals who prefer or require an oral solution over capsules or tablets. This aqueous form may support muscle relaxation, nerve function, and healthy energy metabolism. It's particularly suited for those with swallowing difficulties, sensitive digestion, or a need for flexible, adjustable dosing.
Why It's Worth Considering: Allergy Research Group formulates for practitioners and clinically informed consumers; the liquid delivery format allows for precise dose titration and may offer convenient absorption for those who don't tolerate solid-dose magnesium well.

| Feature | Glycinate | Citrate | Oxide | L-Threonate | Taurate |
|---|---|---|---|---|---|
| Bioavailability | High (chelated) | Moderate-High | Low (4-5%) | Moderate | Moderate-High |
| Best For | Sleep, anxiety, cramps | Constipation, general | Budget (low absorption) | Cognitive function | Heart health |
| GI Tolerance | Excellent | Moderate | Poor (laxative) | Good | Good |
| Laxative Effect | None | Mild–Moderate | Strong | None | None |
| Evidence | Strong | Strong | Weak | Emerging | Moderate |
Magnesium glycinate (bisglycinate chelate) is widely considered the best form for sleep, anxiety, and muscle cramps due to high bioavailability and zero laxative effect. Citrate is better for constipation. Threonate may be superior for cognitive function as it crosses the blood-brain barrier. Oxide has only 4-5% absorption and is primarily a laxative.
No. Unlike magnesium citrate and oxide which draw water into the intestines (osmotic laxative effect), glycinate is chelated and absorbed through a different pathway that does not affect GI motility. It is the most GI-friendly magnesium form available.
Take 1-2 hours before bed for sleep benefits. The glycine component promotes relaxation via GABA receptor activity. For general supplementation, any time works, glycinate does not require food for absorption.
Standard blood tests (serum magnesium) are unreliable, only 1% of body magnesium is in the blood. Signs include muscle cramps, poor sleep, anxiety, eye twitches, chocolate cravings, and headaches. Since 80%+ of adults are suboptimal, supplementation is generally recommended.
Yes, but separate from zinc, calcium, and iron by 2+ hours (they compete for absorption). Magnesium pairs well with Vitamin D3, K2, and B6 taken together.
The RDA is 310-420mg/day for adults. Most functional medicine practitioners recommend 400-600mg for therapeutic benefit. Start with the product's recommended dose and adjust based on response.
