Magnesium Chloride Hexahydrate vs Magnesium Chloride

It’s well-known that magnesium chloride is the best form of magnesium. But it’s still not that simple, given the differences between typical magnesium chloride vs magnesium chloride HEXAHYDRATE. 

The hexahydrate form contains six water molecules bound to each magnesium chloride molecule. Why does that matter, though? It all comes back to bioavailability. This form is much better absorbed by the body, so your cells can actually use more of the magnesium you take in.

We’ll talk more about the differences between magnesium chloride hexahydrate vs magnesium chloride below, and why the distinction matters for energy, stress recovery, muscle tension, and overall nutrient absorption.

But if you’re just looking for the best way to take advantage of the hexahydrate form, your search ends at Flewd Stresscare. Every magnesium bath soak delivers the most usable magnesium with targeted vitamins, minerals, and amino acids to help your body recover faster.

Key Takeaways on Magnesium Chloride Hexahydrate vs Magnesium Chloride

Feature

Magnesium Chloride Hexahydrate

Magnesium Chloride (General)

Chemical Form

Fully hydrated form of magnesium chloride with 6 water molecules (MgCl₂·6H₂O)

Base compound (MgCl₂), may be anhydrous or partially hydrated

Solubility in Water

Very high solubility; dissolves quickly and evenly in water

Good solubility, but can dissolve more slowly or inconsistently depending on grade

Bioavailability

Highly bioavailable; body absorbs and uses it efficiently

Generally well-absorbed, but less predictable than pure hexahydrate

Structure Consistency

Fixed, stable hydration state (always 6 water molecules)

Hydration level can vary between products and batches

Common Formats

Bath soaks, topical sprays, oils, and clinical-grade topical products

Flakes, pellets, tablets, and some oral supplements

Digestive Tolerance

Very gentle when used topically; bypasses the digestive system

Oral forms may cause GI upset in some people (depending on dose and format)

Used In Flewd Stresscare?

Yes – core magnesium source in all soaks

No – Flewd is built specifically around the hexahydrate form

What is Magnesium Chloride?

Magnesium chloride is a salt made from magnesium and chloride ions. It’s found naturally in seawater and salt lakes, and it’s one of the most dependable sources of magnesium because it dissolves so easily in water. That matters for topical absorption.

This form releases magnesium in a form that your body can actually use for energy production, nerve function, muscle relaxation, and stress recovery. This alone makes magnesium chloride better than most other forms, such as magnesium taurate vs glycinate.

Most magnesium chloride is found in flakes, powders, oils, or lotions. People use it for everything from muscle soreness to sleep support because it absorbs way better than most other types. 

But here’s where the nuance between magnesium chloride hexahydrate vs magnesium chloride comes into play. “Magnesium chloride” can refer to a variety of hydration states. Some versions are partially dehydrated, some have residual moisture, and others exist in pure anhydrous form.

These differences affect solubility, absorption, and overall bioavailability. That matters for anyone using magnesium no matter the goal. So, let’s introduce the other half of our magnesium chloride vs magnesium chloride hexahydrate comparison.

What is Magnesium Chloride Hexahydrate?

The magnesium chloride hexahydrate is the most hydrated form of this particular mineral. It has six molecules attached to each magnesium chloride unit. That totally changes the way your body absorbs and uses it - for the better!

Those water molecules improve stability. It makes the compound smaller and highly soluble, too, so it’s way easier for your body to soak up the magnesium and ensure it actually reaches your cells where it can get put to use. 

Magnesium chloride hexahydrate is also exceptionally gentle, which can make a huge difference for anyone who has tried other forms of magnesium and dealt with digestive side effects.

It’s available in all the same forms as other types of magnesium chloride - bath soaks, sprays, and topical applications. Remember, the body doesn’t waste effort breaking down this mineral with transdermal methods. The magnesium enters the bloodstream effortlessly, where it can support ATP energy production, ease muscle tension, calm overstimulated nerves, steady stress responses, and improve sleep quality.

This is the form used in clinical-grade topical magnesium products for a reason: it delivers the highest usable magnesium with the least irritation or loss along the way. But is it really the right epsom salt substitute for you?

Magnesium Chloride Hexahydrate vs Magnesium Chloride: Is One Better Than the Other?

You can see why the distinction between magnesium chloride hexahydrate vs magnesium chloride is so important. While both come from the same base compound, they behave very differently once they hit your body.

Regular magnesium chloride can be a little hit or miss in terms of purity and hydration level. That influences how well it dissolves and how much usable magnesium you actually absorb. 

In contrast, you know magnesium chloride hexahydrate has a consistent structure with six bound water molecules. It’s way more soluble and predictable. That extra hydration gives your body a cleaner, easier path to pull magnesium into the bloodstream, especially topically.

We think the differences between magnesium chloride hexahydrate vs magnesium chloride tell you everything you need to know. Hexahydrate dissolves instantly, spreads evenly in water or on skin, and delivers a higher percentage of elemental magnesium your body can actually use.

This translates to better support for energy production, muscle relaxation, sleep quality, and stress recovery compared to partially hydrated or anhydrous magnesium chloride. But don’t just take our word for it. Feel the difference firsthand at Flewd Stresscare.
