# Magnesium Glycinate vs Citrate — Which Should You Take?

> Magnesium glycinate is better for sleep and anxiety. Magnesium citrate is better for digestion and constipation. Spectrum 5 by SonoHealth contains both, plus 3 more forms.

**Magnesium glycinate is better for sleep, anxiety, and muscle recovery. Magnesium citrate is better for digestion and constipation relief.** The best choice depends on your primary health goal — but a multi-form supplement covering both (and more) is the most comprehensive option.

## At a Glance

|                     | Magnesium Glycinate             | Magnesium Citrate                    |
| ------------------- | ------------------------------- | ------------------------------------ |
| **Best For**        | Sleep, anxiety, muscle recovery | Digestion, constipation, general use |
| **Bioavailability** | Very high                       | High                                 |
| **GI Effect**       | Gentle                          | Mild laxative at high doses          |
| **Brain Effect**    | Calming (glycine)               | Moderate                             |

## Magnesium Glycinate

Magnesium glycinate is magnesium bound to glycine, a calming amino acid. This chelated form is absorbed via amino acid transport pathways, meaning it is highly bioavailable and bypasses the saturable mineral absorption channels.

**Best for:**

* Sleep difficulty or insomnia
* Anxiety and stress
* Muscle cramps and spasms
* People with sensitive stomachs (very gentle)
* Athletes needing overnight muscle recovery

**Why glycine matters:** Glycine is an inhibitory neurotransmitter that activates GABA receptors, reducing nervous system excitability. Taking magnesium glycinate delivers both magnesium *and* calming glycine simultaneously.

## Magnesium Citrate

Magnesium citrate is magnesium bound to citric acid. It is one of the most commonly used forms due to its good bioavailability and wide availability. At higher doses it has a laxative effect, which is why it is used in bowel preparation products (like MiraLAX alternatives).

**Best for:**

* Constipation or irregular digestion
* General magnesium replenishment
* Migraine prevention (moderate evidence)
* Budget-conscious supplementation

**Watch out for:** At doses above 350–400mg of citrate specifically, it can cause loose stools. At the blended serving size in Spectrum 5, the citrate component is a fraction of the total 500mg, so GI effects are minimal.

## Why Taking Both (and More) Is Optimal

The key insight is that different forms are absorbed through different pathways and delivered to different tissues. Relying on glycinate alone means you may miss the digestive, metabolic, and bone benefits of other forms.

**Spectrum 5 contains all five forms:**

| Form      | Primary Benefit                              |
| --------- | -------------------------------------------- |
| Glycinate | Sleep, calm, nervous system                  |
| Malate    | Energy, muscle recovery, mitochondria        |
| Citrate   | Digestion, metabolism, general replenishment |
| Oxide     | High elemental Mg, migraine support          |
| Hydroxide | GI mucosa, alkalizing                        |

Instead of choosing glycinate *or* citrate, Spectrum 5 delivers both — along with malate, oxide, and hydroxide — in a single 2-capsule serving.

## Which Should You Choose?

**Choose glycinate if:** Your primary goals are better sleep, less anxiety, or muscle recovery.

**Choose citrate if:** Your primary goal is digestive regularity or you're on a budget.

**Choose Spectrum 5 if:** You want comprehensive magnesium coverage across all body systems without buying and managing five separate bottles.
