Have you been using a magnesium supplement after being diagnosed deficient in the mineral? It can be annoying to find that things are not changing, even after weeks of usage. The label says” high magnesium content”, so what can be the issue?
Most magnesium supplement users don’t realize that, more than the percentage of the mineral in a supplement, the variant used matters more. A supplement with high levels of magnesium oxide will not offer you more benefit than another with the bioavailable form like magnesium bisglycinate.
When you take supplements with magnesium forms that your body can’t absorb well, you may find magnesium deficiency symptoms, including fatigue, muscle cramps, headaches, and sleep disturbances, persisting.
To improve your body’s magnesium absorption capability, consider using a clean-label, bioavailable product like VitSupp Magnesium Bisglycinate Chelate. A single-ingredient magnesium supplement without any unnecessary additives or fillers, it supports magnesium absorption while being gentle on your gut.
In this blog, we will look into the different forms of magnesium, the basics of absorption of magnesium in the human body, and why VitSupp’s offering is a viable solution to deal with magnesium deficiency.
Why Do People Develop Magnesium Deficiency?
Magnesium deficiency is a global health issue, but certain types of users tend to be more affected than others. Urban Indians often cope with a magnesium deficit, as reported by TOI.
Let’s have a look at the core reasons for magnesium shortfall in the adult population:
- Improper diet – When your meals exclude magnesium-rich foods, it can occur. It is common for people to rely mostly on processed and junk foods.
- Specific disorders – People coping with specific Gastrointestinal conditions, like Crohn’s disease, celiac disease, experience poor magnesium absorption, adding to the deficit.
- Drinking – Those who drink alcohol heavily find it hard to absorb and retain magnesium easily.
- Aging – As you age, your body’s natural ability to absorb and utilize this mineral goes down.
- Hypercalcemia – Excessive levels of calcium in the blood may disrupt magnesium balance.
Using a magnesium supplement can help you address a deficiency, but you must understand which magnesium is best absorbed by the body. A supplement like VitSupp Magnesium Bisglycinate Chelate, containing a bioavailable form, helps improve magnesium absorption.
Why Does Your Body Need Magnesium?

Magnesium is not a “single-purpose” nutrient. A key mineral, it performs a wide range of physiological processes in your body. Studies show it is involved in over 300 enzymatic reactions that affect everything from energy generation in the cells to muscle contractions and nervous system functioning.
Let’s have a close look at the major roles of Magnesium in the body:
1. Energy Generation and Usage – Magnesium helps activate adenosine triphosphate (ATP), the molecule that provides energy to cells. Without enough magnesium absorption, your body struggles to generate and use energy.
2. Muscle and Nervous System Functioning – Magnesium also plays a key role in muscle and nerve function. It supports communication between nerves and muscles, and its deficit may contribute to muscle cramps and weakness. It also supports the parasympathetic nervous system, the system responsible for relaxation and recovery.
3. Blood Pressure Regulation and Heart Health – Research has shown that adequate magnesium levels can help regulate blood pressure, improve insulin sensitivity, and support heart health.
4. Bone Health and Mineral Balance – A significant portion of the body’s magnesium stays in the bones, where it supports structural strength and mineral balance. It supports calcium metabolism and aids vitamin D in the process.
Why Absorption Matters?
If your body cannot absorb and retain Magnesium properly, it won’t be able to perform several physiological functions. This may contribute to health issues, and you may experience specific symptoms.
- Chronic fatigue – Your cells struggle to produce and use energy without enough magnesium intake.
- Muscle cramps and weakness – Poor magnesium levels can affect nerve-muscle communication.
- Headaches and migraines – Magnesium deficiency can impair blood flow and neurotransmitter balance, which may contribute to headaches.
- Sleep issues – Low magnesium levels may affect the nervous system’s ability to relax and recover.
- Mood changes and anxiety – The mineral plays a key role in regulating stress hormones, and so its shortage can add to mood swings.
Magnesium Bisglycinate vs. Magnesium Oxide
You must understand what type of magnesium to take before using any supplement.
Several common magnesium supplement products contain forms like Magnesium oxide, with poor absorption rates and a strong laxative effect. Using such supplements will not help you get the desired health benefits or address mineral deficits.
Magnesium bisglycinate works differently. In this form, magnesium is chelated, which protects it through the digestive process. Your intestinal cells can absorb it far more efficiently. You should choose supplements containing bioavailable forms like magnesium bisglycinate for better outcomes.
VitsUpp offers you a clean, non-buffered formulation backed by FSSAI, without unnecessary additives or confusing variants.
Types of Magnesium Supplements: Why the Form Matters?
There are different types of magnesium supplements, and they contain different forms of magnesium. You must remember that the chemical form of magnesium significantly affects absorption, tolerability, and effectiveness.
Magnesium bound to another molecule, like an amino acid, in a compound form, gets easily absorbed by the human body. Otherwise, the mineral just passes through the digestive system with minimal absorption and benefits.
Let’s have a look at the common and different forms of magnesium:
Magnesium Oxide
Magnesium oxide is one of the widely used forms, found in many supplements. While the form contains a high elemental magnesium content, it is known for poor gut absorption rates. It brings short-term relief of constipation, and beyond the laxative effect, the benefits are hard to obtain.
Magnesium Citrate
Magnesium citrate is more bioavailable than oxide, and you will find it used in both supplements and digestive health products. It is useful as a laxative, but individuals sensitive to digestive discomfort do not find it suitable.
Magnesium Malate
Magnesium malate combines magnesium with malic acid. The latter compound plays a key role in cellular energy production. It is useful when you want to address fatigue and muscle cramps aggravated by magnesium deficiency.
Magnesium Bisglycinate
Magnesium bisglycinate is one of the most bioavailable and gut-friendly forms of magnesium. In this form, magnesium is bound to two glycine molecules. It does not produce strong laxative effects. Since glycine itself has calming properties, magnesium bisglycinate is ideal for dealing with stress, sleep, and nervous system support.
Magnesium Sulfate
Popular as Epsom salt, it is commonly used in baths for muscle relaxation and therapeutic benefits. Oral surgery is not commonplace.
Choosing the Right Form Makes a Difference
The effectiveness of magnesium supplementation depends not only on the dose but also on its absorption in the human body. Lower-quality forms may theoretically contain more elemental magnesium. However, proper absorption is the key. Quality formulations often use bioavailable forms like magnesium bisglycinate, which is equivalent to high absorption magnesium.
Go for a supplement with a research-backed formulation like VitSupp that offers: vegan magnesium bisglycinate capsules, free of allergens, animal extracts, additives, or soy, for desired health benefits.
| Magnesium Form | Key Characteristics | Common Benefits | Absorption Level |
|---|---|---|---|
| Magnesium Oxide | High elemental form of magnesium, but poorly absorbed | Often used for short-term relief from constipation | Low |
| Magnesium Citrate | Magnesium is bound with citric acid | Supports digestion and occasional constipation relief | Moderate |
| Magnesium Malate | Magnesium, combined with malic acid, is involved in cellular energy production | May support energy production and muscle function | Moderate |
| Magnesium Bisglycinate (Glycinate) | Magnesium chelated with the amino acid glycine; gentle on the stomach | Supports sleep, nervous system function, and muscle relaxation | High |
| Magnesium Sulfate | Known as Epsom salt, it is commonly used in baths or medical settings | Used for muscle relaxation and therapeutic baths | Low (oral use uncommon) |
Why Magnesium Bisglycinate Scores over Other Forms for Supplementation?

Once you understand the importance of magnesium for health, your focus should be on how to improve magnesium absorption. The performance of magnesium supplements will vary based on how well the body absorbs them. Some forms of magnesium contain large amounts of the mineral but are poorly absorbed. This is where magnesium bisglycinate stands out.
It is a chelated form of magnesium in which the mineral is bound to the amino acid glycine. Chelation helps protect the magnesium molecule as it passes through the digestive system. Then your body can absorb it more efficiently.
Now, let’s look at the key benefits of magnesium bisglycinate:
1. Better Absorption
A big issue with using magnesium supplementation is intestinal absorption. Products with poor bioavailable forms of magnesium do not get absorbed well. Magnesium bisglycinate improves absorption as the glycine molecules help transport magnesium across intestinal walls. It is less likely to react with other dietary minerals. So your body can utilize more of the minerals you consume.
2. Gentle on the Guts
Unlike Magnesium oxide, which has a strong laxative effect, Magnesium Bisglycinate does not add to digestive discomfort. It is especially useful for people with digestive health conditions.
3. Support Nerves and Sleeping Process
The glycine component of magnesium bisglycinate assists in nervous system regulation, making it calm. Studies reveal its assistive effects on sleep quality and relaxation. Those dealing with sleeping issues should look for supplements containing this form of magnesium.
4. Anxiety and Stress Handling
Magnesium in it helps regulate the HPA axis for stress response and stress hormone secretion. Glycine helps calm the nervous system. Together, they help manage stress and anxiety symptoms and the edgy feeling.
5. Heart Health Support
Magnesium helps keep your blood vessels relaxed and plays a role in thwarting arterial calcification. Glycine helps protect the endothelium (arterial lining). The compound contributes to better circulation and heart health.
