Introduction
Magnesium is an essential mineral that your body requires for hundreds of different biochemical reactions. From supporting muscle function to maintaining a steady heartbeat and keeping your energy levels consistent, its role in your daily well-being is undeniable. However, not all magnesium is created equal. If you have ever looked at a supplement shelf, you have likely noticed a variety of names like "citrate," "bisglycinate," "malate," or "oxide."
At Swiss Peak Health, we believe that understanding what you are putting into your body is the first step toward reaching your peak. Choosing the wrong form of magnesium might lead to digestive discomfort or simply mean you aren’t getting the support you expected. The two most popular and effective forms are magnesium citrate and magnesium bisglycinate.
In this article, we will break down the chemistry, the benefits, and the practical differences between these two versions of the mineral. By the end, you will know exactly which one fits your routine and how to choose the right supplement for your needs.
Why the Form of Magnesium Matters
When you take a magnesium supplement, you aren't just swallowing pure magnesium metal. Because magnesium is highly reactive, it must be bound to another molecule to remain stable. This "carrier" molecule determines how well your body absorbs the mineral (its bioavailability) and how it behaves once it enters your digestive system.
The process of binding a mineral to an organic molecule is often called chelation. A chelated mineral is usually easier for the body to recognise and absorb compared to inorganic salts like magnesium oxide. Both citrate and bisglycinate are organic forms, but they use very different carriers.
Quick Answer: The main difference lies in the carrier molecule. Magnesium citrate is bound to citric acid and is often used to support digestive regularity. Magnesium bisglycinate is bound to the amino acid glycine, making it highly absorbable and very gentle on the stomach, often preferred for relaxation and sleep support.
Understanding Magnesium Citrate
Magnesium citrate is one of the most widely used and studied forms of the mineral. It is created by combining magnesium with citric acid, an organic compound found naturally in citrus fruits.
How It Works in the Body
Because citric acid is highly soluble in water, magnesium citrate is very easy for the body to break down. Once it reaches your stomach, it dissociates quickly, allowing the magnesium ions to be absorbed through the intestinal wall.
One unique characteristic of magnesium citrate is its "osmotic" effect. It has a natural ability to pull water into the intestines. This increases the volume and softness of the stool, which is why many people find it helpful for maintaining regular bowel movements.
Common Uses for Citrate
Most people choose magnesium citrate when they want a highly bioavailable magnesium that also provides a little help with digestion. It is also a favourite for active individuals and athletes because it is cost-effective and helps replenish mineral stores lost through sweat.
- Digestive Support: If you feel "backed up" or occasionally sluggish in your digestive habits, the citrate form may help.
- Daily Maintenance: It is an excellent all-rounder for general wellness.
- Efficiency: It is absorbed much better than cheaper forms like magnesium oxide.

Understanding Magnesium Bisglycinate
Magnesium bisglycinate (often simply called magnesium glycinate) is considered the "premium" form of magnesium. In this version, the magnesium is bound to two molecules of glycine. Glycine is an amino acid that serves as a building block for proteins and also acts as a calming neurotransmitter in the brain.
The Power of Chelation
The "bis" in bisglycinate refers to the two glycine molecules. This double-bond creates a very stable structure. Unlike other forms that might break apart early in the digestive tract and cause irritation, bisglycinate often stays intact until it reaches the optimal site for absorption. This is why it is widely regarded as the most "gentle" form of magnesium available.
Common Uses for Bisglycinate
Because glycine itself has calming properties, this form is the top choice for evening routines. It is also the go-to for anyone who has a sensitive stomach or finds that other magnesium supplements cause "the runs."
- Rest and Relaxation: The combination of magnesium and glycine may support a calmer state of mind.
- Sleep Routines: Many people find that taking bisglycinate before bed supports a more restful night.
- Sensitive Stomachs: Because it doesn't have the osmotic (laxative) effect of citrate, it is much easier on the gut.
Key Takeaway: If you want digestive help, go with Citrate. If you want a gentle supplement for rest and mood support, go with Bisglycinate.
Direct Comparison: Citrate vs. Bisglycinate
To help you decide, it is useful to see how these two compare across a few key categories.
| Feature | Magnesium Citrate | Magnesium Bisglycinate |
|---|---|---|
| Carrier Molecule | Citric Acid | Glycine (Amino Acid) |
| Bioavailability | High | Very High |
| Digestive Impact | May promote bowel regularity | Very gentle / No laxative effect |
| Best Time to Take | Morning or Afternoon | Evening or Before Bed |
| Primary Goal | General health & digestive flow | Calm, sleep support, & muscle relaxation |
| Cost | Generally more affordable | Often slightly more expensive |

Bioavailability: Why Absorption Is King
You might see a supplement bottle that claims to have 500mg of magnesium, but that doesn't mean your body will actually use all 500mg. Bioavailability refers to the amount of the nutrient that actually enters your bloodstream to be used by your cells.
Inorganic magnesium salts, such as magnesium oxide or magnesium carbonate, often have very low bioavailability—sometimes as low as 4% to 10%. This means most of the mineral stays in your gut, where it can cause cramping and diarrhoea.
Both citrate and bisglycinate have much higher absorption rates. However, magnesium bisglycinate is generally considered the winner in this category. Because the magnesium is "hidden" between the amino acids, it can use the body’s amino acid transport pathways, which are often more efficient than the pathways used by standard mineral ions.
Myth: "Higher dosage always means better results." Fact: A lower dose of a highly bioavailable form (like bisglycinate) is often more effective—and much more comfortable—than a high dose of a poorly absorbed form (like oxide).
The Importance of Elemental Magnesium
When reading a supplement label for a product like our Magnesium Citrate Tablets 750mg, it is important to understand the difference between the "total weight" and the "elemental weight."
Magnesium is always bound to something else. For example, in magnesium citrate, the "citrate" part takes up some of the weight.
- Total Weight: This is the weight of the entire compound (magnesium + citric acid).
- Elemental Magnesium: This is the actual amount of pure magnesium in the tablet.
At Swiss Peak, we prioritise transparency. We ensure our labels clearly state the strength so you know exactly how much of the actual mineral you are getting in each serving. Always look for the "elemental" amount to ensure you are meeting your daily requirements.
How to Choose the Right Form for Your Lifestyle
Still unsure which one is right for you? Let's look at a few common scenarios.
Scenario 1: The Busy Professional Under Stress
If you find yourself feeling "wired but tired" at the end of the day, you may benefit from magnesium bisglycinate. The glycine bond supports the nervous system and may help you transition from a high-stress workday into a calm evening. It is also less likely to cause an emergency trip to the bathroom during a meeting.
Scenario 2: The Fitness Enthusiast
If you are active, hit the gym regularly, or enjoy long hikes, your body uses magnesium rapidly for muscle contraction and energy production. Magnesium citrate is an excellent choice here. It is highly effective at replenishing stores and helps keep your digestive system moving if you are consuming a high-protein diet, which can sometimes be constipating.
Our Magnesium Citrate Tablets 750mg product page shows serving size and elemental magnesium details if you want the exact specs.
Scenario 3: The Person with a Sensitive Gut
Some people find that even a small amount of vitamin C or certain minerals can upset their stomach. If this sounds like you, avoid the citrate form. Magnesium bisglycinate is specifically designed to be easy on the digestive tract. It is "buffered," meaning it doesn't react as aggressively with stomach acid.
What to Expect When Starting Magnesium
When you start a new supplement routine, it is important to have realistic expectations. Magnesium is not a "magic pill" that works instantly. While some people notice a difference in their digestive habits or muscle comfort within a few hours, other benefits take time.
The First Few Days
You might notice a slight change in your bowel habits (especially with citrate) or a feeling of relaxation shortly after taking bisglycinate. If you experience loose stools, it is a sign that you have either taken too much or that the form you chose (citrate) is too strong for your gut.
After 2–4 Weeks
This is when most people start to notice the cumulative benefits. Your cellular stores of magnesium begin to level out. You may find that you feel less run down in the afternoons or that your sleep quality feels more consistent.
Long Term
Consistency is the key to magnesium supplementation. Maintaining healthy levels supports bone density, cardiovascular health, and metabolic function over the long term.
Bottom line: Magnesium is a foundational mineral. Whether you choose citrate for its efficiency or bisglycinate for its gentleness, the most important factor is taking it daily.
Possible Side Effects and Safety
Magnesium is generally very safe for most adults. Because it is water-soluble, your body is usually quite good at flushing out any excess through urine or stool. However, there are a few things to keep in mind.
- Digestive Issues: As mentioned, magnesium citrate can cause loose stools if taken in high doses. This is usually harmless but can be inconvenient.
- Kidney Function: If you have underlying kidney issues, your body may struggle to clear magnesium. It is essential to consult a healthcare professional before starting any mineral supplement in this case.
- Medication Interactions: Magnesium can interfere with the absorption of certain antibiotics and blood pressure medications. Always leave a gap of at least two hours between taking magnesium and other medications.
Note: We recommend that anyone who is pregnant, breastfeeding, or under medical supervision consults their GP before adding a magnesium supplement to their routine.
Building Your Daily Wellness Routine
Magnesium doesn't have to work alone. In fact, it often works better when part of a broader wellness strategy. Many of our customers at Swiss Peak Health find that magnesium pairs exceptionally well with other functional supplements.
- For Sleep Support: Combine magnesium bisglycinate with our Sleep Mushroom Cacao Blend in the evening for a powerful wind-down ritual.
- For Energy: Use magnesium citrate alongside our Functional Mushroom Coffee in the morning to support energy metabolism without the jitters.
- For Recovery: Pair your magnesium with our CBD Muscle & Joint Balm after a workout to support both internal and external recovery.

More importantly, we use independent third-party lab testing. This means you don't have to take our word for it—you can see the results for yourself.
We focus on transparency because we know that when you trust your supplements, you are more likely to stick to your routine. And a consistent routine is the only way to reach your peak.
How to Read a Magnesium Label
To ensure you are getting a high-quality product, follow these three steps when reading a label:
- Check the Form: Does it say "Magnesium Oxide" or "Magnesium Citrate/Bisglycinate"? Look for the latter two for better results.
- Look for Elemental Weight: Make sure the label specifies how much actual magnesium is in the serving, not just the weight of the whole tablet.
- Check the Additives: Avoid products with unnecessary artificial colours or heavy fillers. Our tablets are designed to be as clean as possible while remaining easy to swallow.
Practical Tips for Success
- Start Low and Go Slow: If you are new to magnesium, start with one tablet daily. See how your stomach reacts before increasing to the full recommended serving.
- Timing is Everything: Take citrate in the morning for energy and digestion; take bisglycinate in the evening for rest.
- Take with Food: While not always necessary, taking magnesium with a meal can further reduce the chance of an upset stomach and may help absorption.
- Stay Hydrated: Since magnesium (especially citrate) affects how your body handles water, make sure you are drinking enough fluids throughout the day.
Summary: Which One Should You Buy?
Choosing between magnesium citrate and bisglycinate doesn't have to be complicated. It comes down to your personal goals and how your digestive system behaves.
- Choose Magnesium Citrate if: You want a cost-effective, highly absorbable all-rounder that helps keep your digestion regular. It is great for active people and those who don't have a particularly sensitive stomach.
- Choose Magnesium Bisglycinate if: You are focused on relaxation, better sleep, or muscle recovery. It is the best choice for anyone who suffers from digestive sensitivity or wants the most "premium" absorption possible.
At Swiss Peak Health, we are proud to offer British-made, lab-tested supplements that help you achieve your wellness goals for less. We believe that by providing clear information and honest products, we can help you navigate the world of wellness with confidence.
Key Takeaway: Both forms are superior to cheap alternatives like magnesium oxide. The "best" one is simply the one that fits your specific lifestyle needs and stays consistent in your daily routine.

FAQ
Is it okay to take both magnesium citrate and bisglycinate together?
Yes, many people find that a combination works well. You might take a citrate supplement in the morning for energy and digestive support, and a bisglycinate supplement in the evening to help you unwind. Just ensure your total elemental magnesium intake stays within the recommended daily limits.
Does magnesium citrate cause diarrhoea?
In some people, yes. Because it pulls water into the bowel, it has a mild laxative effect. If you experience loose stools, try reducing your dose or switching to magnesium bisglycinate, which is much gentler on the digestive tract.
How long does it take for magnesium bisglycinate to help with sleep?
While some people feel a sense of relaxation within an hour of taking it, the most significant benefits for sleep quality usually appear after 2 to 4 weeks of consistent use. This allows your body's cellular magnesium levels to reach an optimal state.
Can I take magnesium on an empty stomach?
You can, but it isn't always recommended. Taking magnesium with food can help buffer the mineral and reduce the risk of nausea or stomach upset. If you are taking magnesium bisglycinate specifically for its gentle properties, it is usually well-tolerated even without a full meal.
