Magnesium Oxide vs. Glycinate: Which Has Better Absorption 

Understanding magnesium and its different forms, such as magnesium oxide and magnesium glycinate, is like discovering the diverse superheroes working within your body. 

These minerals play crucial roles in maintaining balance, supporting various bodily functions, and ensuring you stay strong and healthy.

Let’s explore the fascinating world of magnesium and its different teams – oxide and glycinate.

What is Bioavailability And Why Does It Matter?

Think of magnesium as a crucial helper for your body’s balance. Magnesium is found in foods like nuts, seeds, and green leafy vegetables. 

Now, let’s talk about bioavailability, focusing on magnesium.

Certain foods, like nuts and seeds, provide magnesium that your body can easily absorb – we call this high bioavailability. It’s like magnesium is in a form that your body quickly recognizes and puts to good use. On the flip side, some processed foods may contain magnesium in a form that’s not as easy for your body to absorb – we call this low bioavailability. It’s like the magnesium is wearing a disguise that makes it a bit more challenging for your body to take in and use effectively.

Choosing foods with high magnesium bioavailability is like giving your body magnesium in its most powerful and accessible form. Your body can then use it efficiently to support things like muscle function, energy production, and even a healthy heartbeat.

So, opting for magnesium-rich foods with high bioavailability is like ensuring that your magnesium is ready to carry out its mission in your body – keeping you strong, energised, and in tip-top shape!

What Is Magnesium Oxide?

Imagine magnesium oxide as a special team player in the world of minerals. It’s like a combination of magnesium and oxygen, working together to support your body.
