Why I Get Slightly Bored of the Glycinate vs Citrate Conversation
I have had the glycinate versus citrate conversation roughly four thousand times. That is not an exaggeration. It is a genuinely useful conversation, and if you want the full version of it, I have written it up in the post Magnesium Glycinate vs Citrate: Which One Should You Take? That covers the basics well.

But here is the thing. Those two forms are not the whole story. Not even close. There are people who come into the shop in Paignton and neither of those forms is actually the right answer for them. They leave with something different, and it works better. That is what this post is about.
If you already know the glycinate and citrate story and you are wondering what else exists, you are in the right place. Let me walk you through the three forms that do not get enough credit: malate, threonate, and taurate. I will tell you who each one suits, and I will be honest about where the evidence is stronger or weaker.
A Quick Word on Why the Form Matters at All
Magnesium does not float around on its own in a capsule. It is always bound to something else, and that something else changes how the magnesium behaves in your body. It affects how well it is absorbed, where it tends to end up, and what side effects you might get. Two products can both say "magnesium" on the label and behave completely differently once you swallow them.
This is why buying the cheapest tub of magnesium oxide from a supermarket is usually a waste of money. Low absorption, poor tolerance, and you end up taking more to get less. The form is the whole decision.
Magnesium Malate: The One for People Who Feel Tired and Achy
Malate is magnesium bound to malic acid. Malic acid is involved in how the body produces energy at a cellular level, specifically in a process called the citric acid cycle. That is not a wild claim; it is basic biochemistry.
Who tends to find malate useful? People who describe themselves as feeling tired in a way that sleep does not fix. People whose muscles feel heavy or uncomfortable without obvious reason. No supplement will cure or treat any condition, and if you have persistent fatigue or muscle symptoms, please talk to your GP before you do anything else.
But as a form of magnesium, malate is well tolerated and tends to sit gently on the stomach. Some people find it slightly more energising than glycinate, which is why I generally suggest glycinate for evening use and malate is worth considering if you want to take magnesium in the morning without feeling sluggish.
Magnesium Threonate: The Brain-Focused Form
This is the interesting one. Threonate is a newer form, and it is the only form of magnesium that has been specifically researched for its ability to cross the blood-brain barrier. The reason it gets attention is that the brain has its own magnesium requirements, and raising magnesium levels in the rest of the body does not automatically mean the brain gets more.
Threonate is bound to threonic acid, a metabolite of vitamin C. The research into it is still relatively early compared to forms like citrate or glycinate, and I will not overstate what we know. But it is the form I point people towards when their primary concern is cognitive function, concentration, or mental clarity rather than sleep or muscle support.
If you have already read the post on magnesium forms and you are taking glycinate for sleep but still feel mentally foggy, threonate is worth considering as an additional or alternative option. Some people run both. Some switch entirely.
I will be honest about the downside: threonate products tend to be more expensive, and you often need a higher dose by capsule count to hit the effective level of elemental magnesium. You are paying for specificity. Whether that specificity matters for you depends on what you are trying to support.
Magnesium Taurate: The Cardiovascular Support Form
Taurate is magnesium bound to taurine. Both magnesium and taurine have EFSA-authorised roles that relate to normal muscle function and normal electrolyte balance. Taurine also has relevance to cardiovascular tissues, which is why taurate attracts interest from people thinking about heart health as part of a broader supplement routine.
I want to be precise here. No supplement will cure or fix any cardiovascular condition, and supplements are not a substitute for medical care. If you have any diagnosed cardiovascular condition or you are on medication for blood pressure or heart rhythm, talk to your GP before adding magnesium taurate or any other supplement to your routine. That is not a legal disclaimer being read out; that is just sensible advice.
For people without those concerns who want magnesium and want the additional context of taurine in the same capsule, taurate is a genuinely interesting option. It is well absorbed, generally gentle on the digestive system, and the combination is logical rather than gimmicky.
We stock Viridian Magnesium Taurate (112mg, 90 Capsules), and it is one of the cleaner products in that category. Viridian do not use unnecessary fillers, which matters to a lot of our customers.

How These Three Forms Compare
| Form | Bound to | Best suited for | Absorption | Cost |
|---|---|---|---|---|
| Malate | Malic acid | Energy support, daytime use, muscle comfort | Good | Moderate |
| Threonate | Threonic acid | Cognitive support, brain magnesium levels | Good (crosses blood-brain barrier) | Higher |
| Taurate | Taurine | Cardiovascular context, electrolyte balance | Good | Moderate |
| Glycinate | Glycine | Sleep, relaxation, sensitive stomachs | Very good | Moderate |
| Citrate | Citric acid | General use, constipation support | Very good | Lower |
What to Do if You Are Not Sure Which Form You Need
Start with what your main concern actually is. Not the vague sense that you should take magnesium, but what you specifically want to support.
- Sleep and wind-down - Glycinate is still my first recommendation here. Viridian Magnesium Bisglycinate is a good product for this.
- Daytime energy support and muscle comfort - Malate is worth trying instead of or alongside glycinate.
- Mental clarity and cognitive support - Threonate is the specific form to look at.
- General magnesium levels and digestive tolerance - Citrate is still solid value. Magnesium Citrate 450mg Capsules by LSC Supplements is our own label and I am proud of it.
- Cardiovascular context with taurine - Taurate is the logical choice, and the Viridian taurate product is the one I trust.
If you are taking multiple supplements or you are on any medication at all, a quick word with your GP before you start is always the right move. Magnesium interacts with certain medications, including some antibiotics and blood pressure drugs.
FAQ
Is magnesium threonate available in the UK?
Yes, though the range is smaller than for glycinate or citrate. It is more commonly found through specialist supplement retailers than supermarkets. Check the elemental magnesium per serving on any product you consider, because the capsule count needed can be higher than other forms.
Can I take more than one form of magnesium at the same time?
Some people do. A common approach is malate in the morning and glycinate in the evening. The main thing to watch is your total elemental magnesium intake across both products. There is no universal upper limit that applies to everyone, but very high doses can cause digestive discomfort. If you are unsure what a sensible total looks like for you, ask a pharmacist or your GP.
Why does magnesium taurate not get mentioned as often as glycinate?
Mostly because glycinate has had more marketing behind it in recent years. Taurate is not a new or fringe form. It is just quieter. The cardiovascular context it sits in means it tends to attract a more specific type of customer rather than the broad sleep and stress market that glycinate targets.
Is magnesium malate the same as magnesium citrate?
No. Both are well absorbed organic forms, but they are bound to different acids. Malic acid is involved in cellular energy production. Citric acid is a different organic acid with different roles. Malate does not have the mild laxative effect that citrate can produce at higher doses, which is one reason some people prefer it.
Do any of these forms contain allergens?
The magnesium compound itself does not contain common allergens. The capsule shell, fillers or manufacturing processes could introduce allergens depending on the brand. Always check the product label. Viridian products are notably free from unnecessary additives, which is part of why I stock them.
