Introduction
Finding the right supplement routine can often feel like a balancing act, particularly when one mineral comes in so many different forms. If you are currently looking at two different bottles—perhaps one labelled magnesium glycinate and another as Magnesium Citrate Tablets 750mg—you may be wondering if it is safe to use both. At Swiss Peak Health, we believe that understanding the "why" behind your supplementation is just as important as the "what."
This article explores whether you can take magnesium and magnesium citrate together, how different forms interact with your body, and the best ways to structure your daily routine for maximum benefit. We will look at the science of bioavailability (how well your body absorbs a substance), the specific roles of various magnesium salts, and the safety limits you should keep in mind. Our goal is to help you navigate these choices with confidence, ensuring your wellness routine is both effective and transparent.
Quick Answer: Yes, you can take different forms of magnesium together, provided your total daily intake remains within the recommended safety limits. Combining forms like magnesium citrate for digestion and magnesium glycinate for sleep can be a strategic way to target multiple wellness goals simultaneously.
The Basics of Magnesium Supplementation
Magnesium is an essential mineral and electrolyte required for more than 300 biochemical reactions in the human body. It is involved in everything from energy production and DNA synthesis to muscle contraction and nerve transmission. However, magnesium does not exist as a standalone molecule in supplements; it must be bound to another substance to remain stable.
This "carrier" molecule determines the name of the supplement and, more importantly, how the body absorbs and uses it. When people ask if they can take "magnesium" and "magnesium citrate" together, they are usually referring to combining citrate with another popular form, such as magnesium glycinate, malate, or oxide.
Understanding Magnesium Citrate
Magnesium citrate is a form of magnesium bound with citric acid. It is one of the most common and well-researched forms available in the UK. One of its defining characteristics is its high bioavailability. Research suggests that organic magnesium salts, like citrate, are generally better absorbed by the gut than inorganic forms like magnesium oxide. For a fuller breakdown of what it is used for, see our guide to What Is Magnesium Citrate For? Practical Uses and Benefits.
Mechanically, magnesium citrate acts as an osmotic laxative. This means it draws water into the intestines, which softens the stool and stimulates bowel movements. Because of this, many people use it specifically to support digestive regularity.
Understanding Other Common Forms
To understand the impact of combining forms, it helps to know what the "other" magnesium is likely to be. If you want a more direct comparison, our guide to Can I Take Magnesium Citrate and Glycinate? walks through the practical differences.
- Magnesium Glycinate: Bound to the amino acid glycine. It is known for being very gentle on the stomach and is frequently used to support relaxation, calm, and sleep.
- Magnesium Malate: Bound to malic acid. This form is often associated with energy production and muscle recovery, making it a favourite for those managing everyday fatigue.
- Magnesium Oxide: A smaller molecule with a high percentage of elemental magnesium but lower absorption rates. It is often used for short-term digestive relief.
Can You Take Magnesium and Magnesium Citrate Together?
The short answer is yes. There is no known negative chemical interaction that occurs when you swallow two different forms of magnesium at the same time. In fact, many high-quality "complex" supplements already contain a blend of three or four different types of magnesium to ensure the body has multiple pathways for absorption.
Taking magnesium citrate alongside another form can be a highly effective strategy if you have multiple health priorities. For example, you might want the digestive support offered by citrate while also seeking the nervous system support associated with glycinate.
The Synergy of Combined Forms
When you combine different forms, you are essentially "hedging your bets" on absorption. The body uses different transporters in the intestinal lining to move minerals into the bloodstream. By providing magnesium bound to different carriers (like an organic acid and an amino acid), you may optimise the total amount of magnesium that successfully enters your system. If you want a closer look at the label math, our guide to Elemental Magnesium in Magnesium Citrate Explained breaks it down.
However, the primary concern when combining supplements is the total "elemental" magnesium dose.
The Importance of Elemental Magnesium
When reading a supplement label, you will often see two different numbers. One is the total weight of the compound (e.g., Magnesium Citrate 750mg), and the other is the amount of "elemental" magnesium. Elemental magnesium refers to the actual weight of the magnesium mineral itself, excluding the weight of the citric acid or glycine it is bound to.
For instance, our Magnesium Citrate Tablets 750mg are formulated to provide a clear, potent dose of elemental magnesium. If you are taking two different supplements, you must add the elemental values together, not the total compound weights.
UK Dosing Guidelines
In the UK, the Food Standards Agency (FSA) and other health bodies provide guidance on daily intake. For most adults, the recommended daily allowance (RDA) for magnesium sits between 310mg and 420mg, depending on age and sex.
| Group | Recommended Daily Amount (mg) |
|---|---|
| Men (19–64 years) | 300 mg |
| Women (19–64 years) | 270 mg |
Note: These are the amounts needed from all sources, including food. When supplementing, the UK government suggests that doses up to 400mg of supplemental magnesium are generally considered safe for short-term use for most adults.

Key Takeaway: Combining magnesium forms is safe and potentially beneficial for absorption, but you must monitor the total "elemental" magnesium across all supplements to stay within the recommended daily limits of roughly 300–400mg.
Why Combine Magnesium Citrate with Other Forms?
Most people choose to combine magnesium citrate with another form to achieve a specific "dual-action" effect. Because magnesium affects so many different systems, one form might not be the perfect fit for every goal.
1. Digestion and Relaxation
This is the most common reason for combination. If someone experiences occasional constipation but also struggles with "tired but wired" feelings at night, they might take magnesium citrate in the morning to support regularity and magnesium glycinate in the evening to support the nervous system. If that sounds familiar, our Sleep collection is a natural place to explore.
2. Muscle Recovery and Energy
Athletes often look for a blend. Magnesium citrate is excellent for replenishing general magnesium levels lost through sweat, while magnesium malate may support the Krebs cycle (the process by which our cells create energy). For this kind of routine-building, you may also want to browse the Recovery & Anti-Aging collection.
3. Avoiding Digestive Sensitivity
While magnesium citrate is well-absorbed, taking a very high dose of it all at once can cause loose stools due to its osmotic effect. By splitting the dose—taking half as citrate and half as a gentler form like glycinate—many people find they can reach their target magnesium levels without any digestive discomfort.
How to Structure Your Magnesium Routine
If you have decided to take magnesium and magnesium citrate together, timing is the most effective way to manage your routine.
Step 1: Determine Your Total Goal
Calculate how much elemental magnesium you need. If you eat a diet rich in leafy greens and nuts, you might only need 150–200mg of supplemental magnesium. If your diet is lower in these foods, you might aim closer to 300mg.
Step 2: Split the Timing
Divide your doses between the morning and the evening.
- Morning: Take your magnesium citrate. This supports energy metabolism throughout the day and encourages digestive regularity, and it can fit neatly alongside our Energy collection.
- Evening: Take your "gentle" magnesium (like glycinate). This allows the glycine component to support relaxation and sleep quality, making it a sensible match for our Stress & Calm collection.
Step 3: Monitor and Adjust
Start with a lower dose of each and see how your body responds. If your stools become too loose, reduce the amount of magnesium citrate. If you feel too groggy in the morning, adjust the timing of your evening dose.
Potential Side Effects and Cautions
While magnesium is generally very safe, taking too much—especially when combining multiple products—can lead to side effects.
Digestive Issues
The most common sign that you have exceeded your "bowel tolerance" is diarrhoea or abdominal cramping. This is almost always caused by the osmotic effect of the magnesium drawing too much water into the gut. If this happens, simply reduce the dose of magnesium citrate or spread your intake more thinly across the day.
Kidney Function
Your kidneys are responsible for filtering out excess magnesium. If you have any history of kidney disease or reduced renal function, you must consult your GP before starting or combining magnesium supplements. In these cases, the body can struggle to clear the mineral, leading to a build-up in the blood (hypermagnesemia).
Medication Interactions
Magnesium is a chemically active mineral that can interfere with how certain medications are absorbed.
- Antibiotics: Magnesium can bind to certain antibiotics (like tetracyclines and quinolones), preventing the body from absorbing the medicine. Take them at least two hours apart.
- Thyroid Medication: Magnesium can interfere with the absorption of levothyroxine. It is usually recommended to separate these by at least four hours.
- Osteoporosis Meds (Bisphosphonates): Magnesium can reduce the effectiveness of these drugs.
Note: Always consult a healthcare professional if you are taking prescription medication, particularly for blood pressure, heart rhythm, or bone density, before adding multiple magnesium supplements to your diet.

Lifestyle Factors for Magnesium Absorption
Supplementation is most effective when supported by a healthy lifestyle. Certain factors can either help or hinder how well you absorb the magnesium you take.
Factors That Help
- Vitamin D: Healthy levels of Vitamin D are associated with better magnesium absorption in the gut.
- Healthy Gut Microbiome: A diet rich in prebiotic fibres (like inulin or chicory root) can lower the pH of the distal colon, which may increase the solubility and absorption of magnesium.
Factors That Hinder
- Excessive Phytic Acid: Found in unfermented grains and some legumes, phytates can bind to magnesium and prevent absorption.
- High Alcohol Intake: Alcohol acts as a diuretic and increases the amount of magnesium excreted by the kidneys.
- High Caffeine Intake: Like alcohol, excessive caffeine can slightly increase the loss of minerals through urine.

FAQ
1. Is it better to take magnesium citrate in the morning or at night?
Magnesium citrate is generally best taken in the morning or afternoon. Because it supports energy metabolism and has a mild osmotic effect on the bowels, taking it earlier in the day ensures that its digestive benefits occur during your waking hours rather than disrupting your sleep. If sleep is your main goal, our guide to Best Magnesium for Sleep: Is Citrate or Glycinate Better? goes into more detail.
2. Can I take magnesium citrate and magnesium glycinate at the same time?
Yes, you can take them together. Many people find that taking a smaller dose of each allows them to enjoy the digestive support of citrate and the calming effects of glycinate without overwhelming their digestive system with a single high dose of one form. For a deeper comparison, see Is Magnesium Glycinate or Citrate Better for You?.
3. What happens if I take too much magnesium?
The most common side effect of excessive magnesium intake is diarrhoea, nausea, and stomach cramps. In rare cases of extreme over-supplementation, it can lead to more serious issues like low blood pressure or lethargy, which is why it is important to stay within the FSA-recommended guidelines.
4. Does magnesium citrate interact with other vitamins?
Magnesium citrate works well with most vitamins, particularly Vitamin D and Vitamin B6, which can help with its absorption and utilisation. However, it can compete for absorption with high doses of zinc or calcium, so it is often best to take these minerals at different times of the day.
