Introduction
If you have spent any time researching wellness routines, you have likely noticed that magnesium is rarely just "magnesium." It comes in many different forms, each promising slightly different results. Two of the most frequently discussed are magnesium bisglycinate and magnesium citrate. While both provide this essential mineral, they act on the body in distinct ways.
At Swiss Peak Health, we often hear from people who feel stuck between these two choices — explore our Sleep collection if you’re wondering how different formats fit into an evening routine. You might want the digestive support that one offers, but you also want the relaxation benefits of the other. The good news is that you do not necessarily have to choose one over the other. Taking them in combination is a practical strategy used by many to cover multiple wellness bases.
This article will explore how these two forms work, why they are often used together, and how to build a routine that suits your specific lifestyle. We will look at absorption rates, timing, and what to watch out for to ensure you are getting the most out of your supplements.
Quick Answer: Yes, you can take magnesium bisglycinate and magnesium citrate together. These forms are complementary; citrate is often used for digestive regularity, while bisglycinate is a gentle option for relaxation and sleep support.
Understanding the Difference: Bisglycinate vs. Citrate
Before combining supplements, it is helpful to understand what makes them different. Magnesium is a reactive mineral, so it must be bound to another molecule—a "carrier"—to remain stable and be absorbed by your body. The carrier determines how the magnesium behaves once it enters your system.
What is Magnesium Bisglycinate?
Magnesium bisglycinate (often referred to simply as magnesium glycinate) is a chelated form of the mineral. In this version, magnesium is chemically bound to two molecules of glycine, which is an amino acid. Glycine is naturally found in protein-rich foods and acts as a calming neurotransmitter in the brain.
Because it is bound to an amino acid, the body recognises it as a nutrient to be absorbed through protein channels rather than typical mineral pathways. This makes it highly bioavailable—meaning a large percentage of the mineral actually reaches your bloodstream. It is widely considered the "gentlest" form of magnesium, making it a popular choice for those with sensitive stomachs.
What is Magnesium Citrate?
Magnesium citrate is a magnesium salt that is bound with citric acid. This form is also well-absorbed, but it works through a different mechanism. Citrate is "osmotic," which means it has a natural ability to draw water into the intestines.
This process helps to soften the stool and support healthy bowel movements. While it is excellent for those looking to maintain regularity, taking too much at once can lead to loose stools. For this reason, many people view citrate as a functional form of magnesium for digestive health.
The Logic of Taking Them Together
The primary reason to take both magnesium bisglycinate and magnesium citrate together is to gain the unique benefits of each without the drawbacks of taking a high dose of just one form.
Many people find that a high dose of magnesium citrate causes digestive upset, even if they need that amount of magnesium to support their overall wellness. By "splitting" the source, you can get the digestive support from a smaller dose of citrate and fill the rest of your daily requirement with the gentle bisglycinate.
Common reasons for combining these forms include:
- Targeted Support: You may want digestive regularity in the morning but want to support a calm state of mind before bed.
- Sensitivity Management: You need a higher total amount of magnesium but find that citrate alone causes discomfort.
- Broad-Spectrum Absorption: Using different pathways for absorption (amino acid channels vs. osmotic salts) may help ensure more of the mineral is utilised by the body.
Key Takeaway: Combining different forms of magnesium allows you to customise your intake based on your specific needs—such as digestive regularity and evening relaxation—without overwhelming your digestive system.
Bioavailability and How They Are Absorbed
Bioavailability refers to the proportion of a substance that enters the circulation when introduced into the body and is so able to have an active effect. Magnesium is notoriously difficult for the body to absorb. In fact, we only absorb about 30% to 40% of the magnesium we eat from food.
Magnesium Bisglycinate has high bioavailability because the glycine molecules protect the magnesium from being broken down by stomach acid or binding with other substances (like phytates in grains) that could block its absorption. This "stealth" entry into the body is why it rarely causes a laxative effect.
Magnesium Citrate also has good bioavailability compared to cheaper forms like magnesium oxide, but its osmotic nature means that some of the magnesium stays in the gut to do its work there. This is why it is effective for digestion but slightly less efficient at raising systemic magnesium levels than bisglycinate.
Elemental Magnesium: Reading the Label Correctly
When you look at a supplement bottle, you might see a high number like "1,000mg" on the front. However, it is vital to distinguish between the total compound weight and the elemental magnesium.
The total weight includes the carrier (the glycine or citric acid). Elemental magnesium is the actual amount of the mineral itself. For example, magnesium citrate is usually about 11% to 16% elemental magnesium. If a tablet contains 750mg of magnesium citrate, you may only be getting around 100mg of actual magnesium.
When combining two different products, always check the "Amount Per Serving" section on the back of the label to find the elemental weight. This helps you stay within the recommended daily limits and ensures you are not under-dosing or over-dosing. Our Magnesium Citrate Tablets 750mg | 60 Servings are designed to provide a clear, practical dose of the mineral to help you manage your daily intake with ease.
Building a Routine: Morning vs. Evening Timing
One of the best ways to take these two forms together is to stagger your timing. This aligns the specific characteristics of each supplement with your body’s natural daily rhythms.
The Morning Approach (Citrate)
Many people choose to take magnesium citrate in the morning or early afternoon. Since it supports digestive regularity, taking it earlier in the day allows it to work through the digestive tract when you are active. It can also support energy metabolism throughout the day, as magnesium is a key component in the production of ATP (the body's energy currency). If you are building a daytime stack, take a look at our Energy collection for complementary options.
The Evening Approach (Bisglycinate)
Magnesium bisglycinate is almost universally recommended for evening use. Because glycine has its own calming properties, it may help you unwind after a long day. Many people find that taking bisglycinate about 30 to 60 minutes before bed supports better sleep quality and helps the body transition into a relaxed state. A soothing evening drink like our Sleep Mushroom Cacao Blend | 60 Servings can also be a nice ritual alongside an evening magnesium.
| Feature | Magnesium Citrate | Magnesium Bisglycinate |
|---|---|---|
| Best Timing | Morning / Midday | Evening / Before Bed |
| Primary Goal | Digestion & Regularity | Relaxation & Sleep Quality |
| Stomach Impact | May cause loose stools | Very gentle |
| Absorption | Good | Excellent |
Practical Tips for Starting a Combined Routine
If you are new to using both, don't rush into high doses. Magnesium is a mineral that your body needs to adjust to.
- Start Low and Go Slow: Begin with a small dose of one form for a few days. Once you know how your body reacts, add the second form.
- Monitor Your Digestion: If you notice your stools becoming too loose, you may be taking too much citrate. You can reduce the citrate and increase the bisglycinate to maintain your total magnesium levels.
- Consistency is Key: Magnesium is not a "one-off" supplement. Most people notice the best results when they maintain a consistent daily routine for several weeks.
- Stay Hydrated: Because magnesium (especially citrate) interacts with water in your gut, staying well-hydrated helps the supplement work effectively and prevents any potential discomfort.
Bottom line: A "split-dose" strategy—taking citrate in the morning and bisglycinate at night—is the most effective way for most people to combine these supplements without digestive issues.
Factors That Influence Your Magnesium Needs
While general guidelines exist, several factors in your daily life might mean you require more support from a combination of magnesium supplements.
Activity Levels and Exercise
When you sweat, you lose electrolytes, including magnesium. Those who exercise regularly may find that a combination of these supplements helps with muscle recovery and prevents the cramping that can sometimes follow a hard workout. Magnesium citrate is often used post-workout to help replenish lost minerals and support muscle relaxation. To complement mineral support, some customers also explore our NMN = NAD+ Supplement (600mg per Serving) for cellular energy and recovery.
Stress and Busy Lifestyles
The body uses up magnesium faster during times of high stress. When your "fight or flight" response is active, magnesium is excreted more rapidly through the urine. If you have a particularly demanding week, using magnesium bisglycinate in the evening may help support your nervous system and replenish those depleted stores. For daytime mental clarity while managing stress, consider our Lion's Mane Gummies | 2000mg 30 Pack as part of a balanced routine.
Dietary Habits
If your diet is high in processed foods, sugar, or caffeine, you might be getting less magnesium than you think. Phytic acid (found in some grains) and oxalates (found in spinach) can also interfere with how much magnesium you absorb from food. Supplementing with both forms ensures that you are bridging the gap left by dietary inconsistencies.
Safety, Dosing, and UK Guidelines
In the UK, the NHS and other health bodies suggest that the amount of magnesium you need depends on your age and sex. Generally, for adults, the recommended daily intake is between 270mg and 300mg from all sources, though many wellness practitioners suggest that higher amounts may be beneficial for certain goals.
It is important to note that the "Tolerable Upper Limit" for supplemental magnesium—the amount you take in addition to your food—is often cited as 350mg per day. Exceeding this limit is generally safe for short periods, but doing so long-term can lead to a build-up of the mineral, particularly if your kidneys are not functioning at 100%.
Note: If you have a history of kidney issues, always consult a healthcare professional before starting or combining magnesium supplements. The kidneys are responsible for filtering out excess magnesium, and if they are compromised, levels can become too high.
Potential Interactions to Watch For
Magnesium is a powerful mineral that can interact with certain medications and other supplements. When you are taking two different forms, these interactions remain the same, but it is worth being mindful of them.
- Antibiotics: Magnesium can bind to certain antibiotics (like tetracyclines), preventing them from being absorbed properly. It is usually recommended to wait at least two hours between taking magnesium and an antibiotic.
- Blood Pressure Medication: Since magnesium can support healthy blood pressure, taking it alongside prescription medication might cause blood pressure to drop too low.
- Bisphosphonates: These are often used for bone health. Magnesium can interfere with their absorption, so they should be taken at least two hours apart.
- Zinc Supplements: Taking very high doses of zinc (over 140mg) alongside magnesium may interfere with how the magnesium is absorbed.
If you are under medical supervision or taking any regular prescription medication, it is always a wise idea to speak with your GP or a pharmacist before adding new supplements to your routine.
Why Quality and Sourcing Matter
When choosing your magnesium, look for brands that prioritise transparency. Because supplements are not regulated in the same way as medicines, the quality can vary wildly between brands.
At Swiss Peak Health, we believe that high-quality wellness should be accessible to everyone. All our products, including our magnesium range, are British-made and undergo independent third-party lab testing. This ensures that what is written on the label is exactly what is inside the bottle, with no hidden fillers or contaminants. For other examples of our UK-made formulations, see the Marine Collagen Tablets 1200mg | 30 Servings which follow the same manufacturing standards.
Using a trusted source for both your citrate and bisglycinate means you can be confident that your "combined" routine is safe and effective. We focus on providing high-strength, affordable options like our Magnesium Citrate Tablets 750mg | 60 Servings to help you hit your daily targets without the unnecessary hype.
Myth: "Higher strength always means a better supplement." Fact: Bioavailability and the form of the mineral (like bisglycinate) often matter more than the total milligrams. A smaller dose of a well-absorbed form is often more effective than a huge dose of a poorly absorbed one like magnesium oxide.
Signs You Might Be Taking Too Much
While magnesium is generally very safe, your body will usually let you know if you have overdone it. Because we are combining two forms, it is easier to accidentally exceed your "bowel tolerance."
Common signs of excess magnesium include:
- Diarrhea or loose stools: This is the most common sign and is usually caused by the osmotic effect of magnesium citrate.
- Nausea or stomach cramping: Often a sign that you should take your supplement with food rather than on an empty stomach.
- Lethargy: If you feel overly tired or "heavy," you might be taking too much of the calming bisglycinate.
If you experience these, simply lower your dose for a few days. Most symptoms resolve quickly once the excess magnesium is cleared from your system.
How to Choose the Best Format
When taking magnesium citrate and bisglycinate together, you have options in terms of format—tablets, capsules, or powders.
- Tablets/Capsules: These are the most convenient for most people. They allow for precise dosing and are easy to include in a morning or evening pill organiser. They are also tasteless, which is a bonus as some magnesium powders can have a slightly metallic or bitter aftertaste.
- Powders: These are often used for magnesium citrate because they can be mixed into a drink. This can be helpful for hydration, but it is harder to measure an exact dose compared to a tablet.
For a combined routine, many people find that a high-quality tablet, such as those we provide, offers the most consistency. It allows you to know exactly how many milligrams of elemental magnesium you are getting from each form every single day. If you prefer other supplement formats, explore our All Products collection to compare options across formats and benefit areas.
Conclusion
Combining magnesium bisglycinate and magnesium citrate is a sensible, effective way to support your wellness from two different angles. By using the digestive-friendly citrate in the morning and the calming bisglycinate in the evening, you can tailor your mineral intake to match your body's needs. This approach helps you avoid the common digestive side effects of high-dose magnesium while ensuring your systemic levels remain optimal.

- Adjust the ratio based on how your digestion feels over the following week.
FAQ
1. Is it safe to take both magnesium bisglycinate and citrate at the same time?
Yes, it is perfectly safe to take them simultaneously. Many people find it more effective to split the doses between morning and evening to match the specific benefits of each form, but there is no harmful interaction between the two. Just ensure your total daily intake of elemental magnesium remains within the recommended guidelines.
2. Which form is better for sleep, bisglycinate or citrate?
Magnesium bisglycinate is generally considered superior for sleep support. This is because it is bound to glycine, an amino acid that has its own calming effect on the brain. While citrate can help you relax by supporting muscle function, it doesn't have the same specific neurotransmitter-supportive properties that make bisglycinate a favourite for evening routines.
3. Will taking both cause more stomach upset?
Not necessarily. In fact, combining them may reduce stomach upset compared to taking a high dose of citrate alone. Because bisglycinate is very gentle on the digestive tract, you can use it to reach your desired magnesium levels while keeping your citrate dose low enough to avoid a laxative effect.
4. How long does it take to see results from a magnesium routine?
While some people notice a difference in digestive regularity or relaxation within a day or two, it usually takes consistent use for 3 to 4 weeks to fully replenish the body's magnesium stores. Results vary depending on your starting levels, your diet, and how well your body absorbs the specific forms you are taking. For targeted cellular energy and recovery support, customers often combine magnesium with products like our NMN NAD+ Gummies | 30 Pack or the NMN tablet option mentioned earlier.
