Magnesium is one of the most popular minerals in the wellness worldand for good reason. It supports normal muscle function, contributes to normal psychological function, and helps with normal energy-yielding metabolism. But when you start shopping for supplements, you quickly realise there isnt just one type of magnesium.
Two of the most common options are magnesium bisglycinate and magnesium citrate. Both can be great supplements, but they suit different goals, routines, and sensitivities.
In this guide, well break down the key differences, who each one is best for, and how to choose the right magnesium for you.
Why magnesium matters
Magnesium contributes to:
- Normal muscle function
- Normal functioning of the nervous system
- Normal psychological function
- Reduction of tiredness and fatigue
- Normal energy-yielding metabolism
- Maintenance of normal bones
Because magnesium plays a role in so many processes, its often used as a foundation nutrientespecially for people with busy lifestyles, high stress, or active training schedules.
Magnesium bisglycinate: what it is
Magnesium bisglycinate (sometimes called magnesium glycinate) is magnesium bound to the amino acid glycine.
Why that matters: this form is often chosen for its gentle feel on digestion and its reputation as a calming, well-tolerated option.
Magnesium bisglycinate is often best for:
- People who want a gentler magnesium option
- Those focused on relaxation and evening routines
- People who are sensitive to digestive upset
- Anyone who wants magnesium support without a laxative effect
Many people take magnesium bisglycinate as part of a wind-down routine, especially if theyre building a consistent habit with their daily supplements.
Magnesium citrate: what it is
Magnesium citrate is magnesium bound to citric acid.
This form is widely used and commonly chosen for digestive support, because it can have a more noticeable effect on bowel regularity for some people.
Magnesium citrate is often best for:
- People who want magnesium plus digestive support
- Those who experience occasional constipation
- People who tolerate magnesium well and prefer a more active form
If your main goal is regularity, magnesium citrate is often the first option people trybut its not always the best fit if youre sensitive.
The key differences (simple breakdown)
1) Digestion and tolerance
This is usually the biggest deciding factor.
- Magnesium bisglycinate: typically gentler; less likely to cause loose stools
- Magnesium citrate: can be more likely to loosen stools, especially at higher doses
If youve tried magnesium before and it upset your stomach, bisglycinate is often the more comfortable next step.
2) Your main goal
Ask yourself: what do you want magnesium to do in your routine?
- For relaxation, stress support, and evening routines: bisglycinate is often preferred
- For bowel regularity and digestive support: citrate is often preferred
Both are useful supplements, but the best one is the one that matches your goal.
3) Timing and routine fit
You can take either form at a time that suits you, but many people find:
- Bisglycinate fits well in the evening (wind-down routine)
- Citrate fits well earlier in the day, especially if youre assessing digestive effects
If youre trialling magnesium citrate, it can be smart to avoid taking it right before a long commute or a busy morning until you know how you respond.
Which one should you choose?
Heres a quick decision guide:
Choose magnesium bisglycinate if:
- You want a gentle, well-tolerated magnesium
- Youre focused on relaxation, calm, and sleep routines
- Youve had digestive side effects from magnesium in the past
- You want magnesium support without changing bowel habits
Choose magnesium citrate if:
- Your priority is digestion and regularity
- You tend toward constipation
- You want a widely used, straightforward magnesium option
- You tolerate magnesium well and dont mind a stronger digestive effect
If youre still unsure, many people start with bisglycinate for comfort and consistency, then consider citrate later if digestion is the main goal.
Can you take both?
Some people do use both formsfor example, bisglycinate in the evening and citrate earlier in the day.
However, its important to:
- Avoid stacking too high a total dose
- Introduce one change at a time so you can tell whats working
- Check other supplements you take (multiminerals can already include magnesium)
If youre on medication or managing a health condition, its always best to check with a healthcare professional.
Tips for taking magnesium supplements
To get the most from magnesium supplements:
- Start with a lower dose and increase gradually
- Take with food if youre sensitive
- Be consistent for at least 23 weeks before judging results
- If using citrate, monitor bowel changes and adjust as needed
Also note: magnesium can interact with some medications (including certain antibiotics and thyroid medication). Spacing doses can matterask a pharmacist if youre unsure.

Final thoughts
Magnesium bisglycinate and magnesium citrate are both effective, popular supplements but theyre not interchangeable.
If you want a gentler, calming option, magnesium bisglycinate is often the best place to start. If your main focus is bowel regularity and digestive support, magnesium citrate may be the better fit.
Choose the one that matches your goal, start low, stay consistent, and build a routine you can actually stick to.
