Introduction
Many health-conscious individuals in the UK find themselves staring at a shelf of supplements, wondering which specific "version" of a mineral they actually need. Magnesium is a prime example, as it rarely exists on its own; it is almost always bound to another molecule to help your body absorb it. Magnesium glycinate and magnesium citrate are two of the most popular forms, but they serve different primary purposes. If you are struggling to choose between the calming effects of one and the digestive support of the other, you may be asking if it is possible—or even beneficial—to use both. At Swiss Peak Health, we believe that understanding the science behind your supplements is the first step toward peak wellness, and our magnesium supplements collection is a good place to start exploring the range. This article explores whether you can take both magnesium glycinate and citrate, how to time your doses for the best results, and the safety considerations you need to know.
Quick Answer: Yes, you can safely take both magnesium glycinate and magnesium citrate together. Combining them allows you to benefit from the superior absorption and calming properties of glycinate while utilizing the digestive support of citrate, provided your total daily intake remains within recommended safety limits.
Understanding the Difference: Citrate vs Glycinate
To understand why you might want to combine these two, we must first look at what makes them unique. Magnesium is a "team player" mineral; it needs a carrier molecule to pass through the intestinal wall and enter the bloodstream. The molecule it is "chelated" (bound) to determines how the supplement behaves in your body.
What is Magnesium Citrate?
Magnesium citrate is magnesium bound with citric acid. This is an organic salt that is highly "osmotic," meaning it has a natural ability to pull water into the intestines. Because of this mechanism, it is widely recognised for its ability to support digestive regularity and provide relief from occasional constipation.
Beyond digestion, magnesium citrate is highly bioavailable. Bioavailability refers to the proportion of a nutrient that enters the circulation when introduced into the body and is so able to have an active effect. Because it is absorbed relatively quickly, it is often a preferred choice for general magnesium replenishment. If you want a specific product example, our Magnesium Citrate Tablets 750mg are the form most people are comparing here.
What is Magnesium Glycinate?
Magnesium glycinate consists of magnesium bound to the amino acid glycine. Glycine is a neurotransmitter that has its own calming effect on the brain. When these two are paired, the result is a supplement that is exceptionally gentle on the digestive tract.
Unlike the citrate form, glycinate does not typically have a laxative effect. It is often recommended for those with sensitive stomachs or for individuals looking to support muscle relaxation, sleep quality, and a sense of calm. If sleep is your main goal, our sleep supplements collection is a natural next step. The glycine molecule acts as a chaperone, helping the magnesium pass through the gut with very little irritation.
Can You Take Both Together?
The short answer is yes. In fact, many people find that a "blended" approach is more effective than taking a single form. By taking both, you are essentially targeting different physiological needs. For a deeper comparison, read our guide on Which Magnesium is Best Citrate or Glycinate for You?.
The Synergistic Approach Taking both forms allows you to address two common wellness goals simultaneously. For example, if you require the calming support of glycinate for a better night's rest but also find that your digestion is somewhat sluggish, using a combination allows you to address both without relying on a single high dose of one form that might cause unwanted side effects.
Avoiding the "Flush" One common issue with magnesium citrate is that in high doses, the osmotic effect can be too strong, leading to loose stools. By splitting your "magnesium budget" between citrate and glycinate, you can reach your daily target for elemental magnesium without overwhelming your digestive system.
Key Takeaway: Combining magnesium forms is a strategy to maximise benefits while minimising side effects. It allows for a more tailored approach to mineral supplementation based on individual digestive tolerance and wellness goals.
Bioavailability and Absorption Mechanisms
The reason we can take both forms effectively lies in how the body processes them. Our internal "transport" systems for minerals are complex.
Magnesium Citrate Absorption When you take magnesium citrate, it dissolves easily in stomach acid. Once it reaches the small intestine, it is absorbed through "passive diffusion." This is a process where molecules move from an area of high concentration to an area of low concentration. Because citrate dissolves so well, it creates a high concentration that moves efficiently into the blood. For a deeper breakdown of elemental weight, see How Much Magnesium is in a Bottle of Magnesium Citrate?.
Magnesium Glycinate Absorption Magnesium glycinate uses a different pathway. Because the magnesium is bound to an amino acid, the body treats it more like a protein. It often uses "dipeptide channels" in the gut. These are specialized "doors" that allow amino acids to pass through. This is why glycinate is so gentle; it doesn't rely as heavily on the osmotic processes that can irritate the bowel. If you want a more detailed side-by-side comparison, our guide on Magnesium Citrate or Glycinate: Which is Better for Sleep? is worth a look.
Practical Dosing: How to Take Both
If you decide to incorporate both into your routine, the "when" is just as important as the "how much." Most experts suggest a split routine to align with the body's natural rhythms.
The Morning/Evening Protocol
Morning: Magnesium Citrate Taking magnesium citrate in the morning or early afternoon is often ideal. Because it may support energy metabolism and keeps the digestive system moving, it fits well into a daytime routine. If you are using it for muscle recovery after a morning workout, this timing is particularly effective, and our recovery collection is a helpful place to browse.
Evening: Magnesium Glycinate Magnesium glycinate is almost always best taken in the evening, roughly 30 to 60 minutes before bed. The calming influence of the glycine, combined with the muscle-relaxing properties of magnesium, helps signal to the nervous system that it is time to unwind. If you are building a more consistent bedtime routine, our calm supplements collection is a useful companion.
Step-by-Step: Starting Your Combined Routine
- Calculate your current intake: Look at your diet and any multivitamins you already take to see how much magnesium you are already consuming.
- Start low: If you are new to supplements, start with a low dose of one form (e.g., 100mg of glycinate) for a few days to check your tolerance.
- Introduce the second form: Once you are comfortable, add the citrate form, perhaps with breakfast.
- Monitor your digestion: If you experience loose stools, reduce the citrate dose. If you feel too groggy in the morning, slightly reduce the glycinate dose.
- Be consistent: Like most minerals, the benefits of magnesium are cumulative. It can take several weeks of consistent use to notice a significant change in your baseline wellness.
Understanding Elemental Magnesium
One of the most confusing aspects of magnesium supplementation is the difference between the "compound weight" and the "elemental weight."
When you see a bottle that says Magnesium Citrate 750mg, that 750mg refers to the total weight of the magnesium plus the citric acid. The actual amount of pure magnesium—the "elemental" magnesium—is only a fraction of that total weight (for citrate, it is typically around 15-16%). If you want the dosage side of that conversation broken down in more detail, read Finding the Right Daily Magnesium Citrate Dosage.
At Swiss Peak Health, we prioritise transparency in our labelling. Our Magnesium Citrate tablets are formulated to provide a potent dose while remaining within the safe daily guidelines provided by the UK Food Standards Agency (FSA). Always check the "Supplement Facts" on the back of the bottle to see the actual amount of elemental magnesium you are receiving.
UK Guidelines and Safety Limits
The UK government and the FSA provide clear guidance on the maximum "safe upper limit" for magnesium from supplements. For adults, the general recommendation is not to exceed 400mg of elemental magnesium per day from supplements alone (unless directed by a GP). If you want a practical walkthrough of timing and tolerance, see How Do I Take Magnesium Citrate for Wellness.
Exceeding this limit regularly can lead to:
- Diarrhea and stomach cramping
- Nausea
- Lethargy
- In extreme cases, more serious cardiac or kidney issues
It is important to remember that these limits apply to the supplemental amount, not the amount you get from food like spinach, nuts, and seeds. The body is very good at regulating magnesium from food, but it is less efficient at managing very high doses from concentrated supplements.
Who Should Exercise Caution?
While magnesium is generally very safe, certain individuals need to be more careful, especially when combining different forms.
Those with Kidney Concerns The kidneys are responsible for filtering excess magnesium out of the body. If your kidney function is impaired, magnesium can build up in the blood, leading to a condition called hypermagnesemia. If you have any history of kidney disease, always consult your GP before starting a magnesium regimen.
Individuals on Specific Medications Magnesium can interact with several common medications. It can bind to certain drugs in the digestive tract, preventing them from being absorbed properly.
- Antibiotics: Magnesium can interfere with the absorption of tetracyclines and quinolones. It is usually recommended to take magnesium at least 2 hours before or 4-6 hours after an antibiotic.
- Osteoporosis Medications (Bisphosphonates): Magnesium can reduce how much of the medication the body absorbs.
- Thyroid Medication: Magnesium may decrease the efficacy of levothyroxine.
- Blood Pressure Medications: Since magnesium can naturally lower blood pressure, taking it alongside prescription medication may cause your pressure to drop too low.
Note: Always speak with a healthcare professional or pharmacist if you are taking prescription medication. They can help you create a "dosing window" to ensure your supplements don't interfere with your medicine.

The Role of Magnesium in the Modern UK Diet
Despite being present in many foods, many UK adults do not meet the recommended daily intake for magnesium. Modern soil depletion and the prevalence of processed foods have made it harder to get enough of this mineral through diet alone.
Furthermore, "lifestyle magnesium burners" are common. High stress levels, high caffeine intake, and regular alcohol consumption can all cause the body to excrete magnesium more quickly. This is why many find that a high-quality supplement, like our Swiss Peak Magnesium Citrate, helps bridge the gap between their dietary intake and their body's actual needs. If you want to compare the wider range, shop all products makes it easy to explore.
Why Quality Matters (The Swiss Peak Standard)
Not all magnesium supplements are created equal. Many cheaper options on the high street use "magnesium oxide." While oxide has a high amount of elemental magnesium, its bioavailability is notoriously poor—often as low as 4%. This means most of it stays in your gut, which often leads to digestive upset without providing the systemic benefits you are looking for.
By choosing Swiss Peak Health, you are opting for premium, UK-manufactured supplements that are:
- Third-party lab tested: We verify every batch for purity and potency.
- 100% Vegan and Gluten-free: We believe wellness should be accessible to everyone.
- Transparently Dosed: We provide clear information on elemental magnesium so you can dose with confidence.
You can verify our standards anytime through our lab reports. Our mission is simple: peak health for less. We provide science-backed, high-quality nutrition without the "premium" price tag often found in the wellness industry.
How to Choose the Right Form for Your Goals
If you are still undecided on whether to take one or both, consider your primary wellness goal:
| Goal | Primary Recommendation | Why? |
|---|---|---|
| Better Sleep & Calm | Magnesium Glycinate | The glycine bond supports the nervous system and is ultra-gentle. |
| Digestive Regularity | Magnesium Citrate | The osmotic effect helps soften stool and supports movement. |
| Muscle Recovery | Both (Split Dose) | Citrate for daytime replenishment; Glycinate for nighttime repair. |
| High Sensitivity | Magnesium Glycinate | The amino acid pathway bypasses most digestive irritation. |
| General Deficiency | Magnesium Citrate | Highly bioavailable and cost-effective for daily mineral levels. |

Maximising the Benefits of Your Magnesium Routine
To get the most out of taking both glycinate and citrate, consider these lifestyle factors:
1. Watch Your Zinc Intake While zinc is another essential mineral, very high doses of supplemental zinc (usually over 140mg per day) can interfere with magnesium absorption. If you are taking a high-strength "immune support" complex, check the zinc levels.
2. Hydrate Properly Since magnesium citrate works by drawing water into the bowel, it is essential to stay hydrated. Drinking enough water ensures the citrate can do its job effectively without leaving you feeling dehydrated.
3. Monitor Your Stress When we are stressed, our bodies "dump" magnesium. If you are going through a particularly hectic period at work or home, you might find you need to be more diligent with your evening glycinate dose to help your nervous system recover.
Conclusion
Combining magnesium glycinate and magnesium citrate is a safe and effective way to enjoy the broad spectrum of benefits this mineral offers. By using citrate to support your digestion and general mineral levels during the day, and glycinate to support your sleep and relaxation at night, you create a comprehensive mineral routine that works with your body’s natural clock.
At Swiss Peak Health, we are committed to helping you achieve your health goals through transparency and quality. Whether you are looking to improve your sleep, support your recovery, or simply maintain everyday balance, our UK-manufactured supplements provide a reliable foundation.

FAQ
Can I take magnesium glycinate and citrate at the exact same time?
Yes, you can take them together, but many people prefer to split them. Taking citrate in the morning can support daytime digestion and energy, while taking glycinate in the evening leverages its calming properties for better sleep. If you are still deciding between the two, our guide on Which Magnesium Is Best For Sleep Glycinate Or Citrate? compares the forms in more detail.
Will taking both forms cause a "laxative effect"?
It depends on the dose of the citrate form. Magnesium citrate is known for its osmotic effect which can loosen stools, while glycinate is much gentler. By combining them, you can often get the magnesium you need with a smaller dose of citrate, reducing the likelihood of digestive urgency compared to taking a high dose of citrate alone. For a clearer breakdown of serving size and compound weight, see How Much Magnesium is in a Bottle of Magnesium Citrate?.
Is it better to take these supplements with food?
While magnesium can be taken on an empty stomach, taking it with a meal can often improve tolerance and reduce the risk of nausea. For magnesium citrate specifically, taking it with food may help slow down the osmotic effect, making it even gentler on your digestive system.
How long does it take to feel the benefits of combining these forms?
For digestive support from the citrate form, many people notice a difference within 6 to 12 hours. For the calming and sleep-supporting benefits of glycinate, it may take a few nights of consistent use. For systemic benefits like improved muscle function or reduced tiredness, it typically takes 2 to 4 weeks of daily supplementation to notice a significant change.
