Which magnesium is best

Which magnesium should I use? (Complete guide + best choice)

Magnesium is one of the most popular supplements right now—and for good reason. The mineral supports hundreds of processes in the body, from energy to muscle function and relaxation. But as soon as you want to buy magnesium, you'll discover that there are countless types: citrate, bisglycinate, oxide, malate, taurate… and so on.

The big question is: which magnesium should you use?
In this article, we'll explain it clearly and you'll discover why magnesium citrate and magnesium bisglycinate are the best choices for most people.

Why do so many people take magnesium?

Magnesium is involved in over 300 enzymatic processes in the body. It supports, among other things:

✅ normal muscle function
✅ normal functioning of the nervous system
✅ reduction of fatigue
✅ normal energy metabolism
✅ maintain strong bones and teeth
✅ normal psychological function (mental resilience)

Because magnesium has such a broad spectrum of effects, people often use it in situations such as a busy life, sports activities, stress, tension or as a supplement to a less varied diet.

But… not every form of magnesium is absorbed equally well. And that's precisely the difference.

Why are there so many types of magnesium?

Magnesium is a mineral and cannot exist as a supplement on its own. Therefore, it is combined with another substance (e.g., citric acid or an amino acid). This creates a magnesium compound.

This connection mainly determines:

• How well your body absorbs it (bioavailability)
• How gentle it is on the stomach and intestines
• What it is often used for (relaxation, muscles, energy, bowel movements)

Some shapes are therefore super popular… but in practice they are not the best choice.

The 2 best choices: magnesium citrate & magnesium bisglycinate

1) Magnesium citrate > Popular, effective and widely applicable

Magnesium citrate is magnesium bound to citric acid. It is one of the most commonly used forms because it:

✅ is well absorbed by the body
✅ widely applicable (muscles, energy, general support)
✅ often has a beneficial effect on bowel movements
✅ a top choice as “ all-round magnesium ”

Who is magnesium citrate ideal for?

• People looking for a well-absorbable magnesium for daily use
• People who take magnesium for muscles and energy
• People who notice that stress and pressure cause physical tension
• People who are sensitive to constipation (citrate may have a slightly gentler effect)

Additional benefit:
Magnesium citrate is often chosen as an “entry-level form”: effective, well-known and easy to use.

2) Magnesium bisglycinate > The best choice for relaxation and sensitivity

Magnesium bisglycinate (also called magnesium glycinate) is magnesium combined with the amino acid glycine. This makes it a real favorite, especially among people who take magnesium for relaxation.

✅ highly absorbable
✅ gentle on the stomach and intestines
✅ ideal for stress and tension
✅ is often chosen for the evening

Who is magnesium bisglycinate ideal for?

• People who want magnesium for peace of mind
• People who want to use it in their evening routine
• People with a sensitive stomach/intestines
• People who do not tolerate magnesium oxide well

Many people find bisglycinate to be the “most comfortable” form: no strange side effects, no bloating and usually no laxative effect.

Magnesium Citrate vs. Bisglycinate: Which Should You Choose?

Good question, because both are great. It mainly depends on your goal:

Choose magnesium citrate if you…
✅ looking for an all-round magnesium
✅ want support for muscles and energy
✅ also want to support your bowel movements

Choose magnesium bisglycinate if you…
✅ mainly looking for relaxation and peace
✅ want to take magnesium in the evening
✅ are sensitive to your stomach/intestines

Tip: Many people use citrate during the day and bisglycinate in the evening, but one type is often enough.

Why magnesium oxide is less good (and still sells a lot)

Magnesium oxide is unfortunately one of the most common forms of magnesium in cheap supplements. Not because it's the best, but because it's cheap to produce and seems to contain a lot of "elemental magnesium" on the label.

The problem?
👉 Magnesium oxide is poorly absorbed by the body.

What you often see:

• Lower bioavailability
• Increased risk of stomach/intestinal complaints
• You need more to achieve the same effect, so not that cheap after all.

That is why many people ultimately opt for citrate or bisglycinate once they notice the difference.

In short:

✅ Citrate and bisglycinate = good absorption, effective
❌ Oxide = lower absorption, often “cheap but less ideal”

Other types of magnesium (briefly explained)

You'll also find many other forms online. A brief explanation:

• Magnesium malate : Often mentioned for energy (malic acid), but less popular than citrate/bisglycinate. It is well absorbed, but has a sour taste due to the malic acid.
• Magnesium taurate : Magnesium with taurine is often chosen for specific preferences. We recommend simply taking a separate taurine supplement if you think this form is best for you. Taurine is almost free, and if you buy magnesium citrate and taurine separately, you'll likely save even more and get two quality products.
• Magnesium L-threonate : Expensive, often marketed around “brain,” but not necessarily needed for most people looking for a magnesium supplement.
• Magnesium chloride : A reasonably absorbable form of magnesium, but better options are available. The taste and stomach effects can also be issues with this form of magnesium.

For 90% of people:
Magnesium citrate or bisglycinate is the smartest choice.

When is the best time to take magnesium?

During the day (morning/afternoon)
➡️ Magnesium citrate often fits well here, especially if you use it for energy/muscles.

Evening
➡️ Magnesium bisglycinate is popular in the evening routine because of its gentle and relaxing character.

With or without food?

• Eating is often the most comfortable
• For a sensitive stomach, “after the meal” is usually ideal

How much magnesium do you need?

This varies by person and situation (diet, exercise, stress). Many supplements have a practical daily dose, often divided into 1–2 doses.

Important: More isn't always better. Choose quality and good absorption over a cheap form with high milligram counts on the label.

Common mistake: choosing “highest mg” instead of uptake

A common mistake is that people choose magnesium oxide because it says "400 mg magnesium." But if your body barely absorbs it, you'll ultimately get less benefit.

Therefore, this is a better approach:

✅ Choose a shape with good absorption
✅ Check if it is gentle on your stomach/intestines
✅ Match the form with your goal (all-round vs. relaxation)

And that is exactly why we keep coming back to: magnesium citrate and magnesium bisglycinate .

Conclusion: which magnesium should I use?

If you're unsure about which magnesium to take, keep it simple:

✅ Magnesium citrate is the best all-around choice
✅ Magnesium bisglycinate is ideal for relaxation and sensitivity
❌ Magnesium oxide is often less effective due to low absorption

Looking for a magnesium supplement that actually works? Citrate and bisglycinate are the smartest choices for most people.
