Magnesium Glycinate Tablets: Best for Restful Sleep, Calm and Sustained Natural Energy

If you’re seeking a high-quality magnesium supplement to support better sleep, emotional balance, and muscle recovery, Magnesium Glycinate tablets stand out as a top-tier choice. VitaBright’s Magnesium Glycinate Tablets are formulated for purity, potency, and bioavailability, delivering 300 mg of elemental magnesium per serving with no additives or allergens. Let’s explore the benefits of this remarkable supplement and why it's become a customer favourite for natural, daily support.

What Is Magnesium Glycinate?

Magnesium Glycinate is a highly absorbable form of magnesium, chelated with the amino acid glycine. This pairing allows magnesium to pass more efficiently through the intestinal wall, ensuring higher bioavailability compared to other forms such as magnesium oxide or citrate. Because it is gentle on the stomach and unlikely to cause gastrointestinal upset, magnesium glycinate tablets are ideal for daily supplementation, even if you have sensitive digestion.

Why Choose Magnesium Glycinate Tablets from VitaBright?

High Strength, Effective Dosage

Each serving of VitaBright’s Magnesium Glycinate tablets provides 1500 mg of magnesium glycinate, supplying 300 mg of elemental magnesium. This meets 80% of the Nutrient Reference Value (NRV), aligning with the NHS-recommended daily intake for both men and women. With 180 capsules per bottle, this is a full 3-month supply, offering outstanding value for a premium-grade supplement.

Pure, Clean Formula

Unlike many magnesium supplements on the market, VitaBright’s clean formulation contains no additives, preservatives, bulking agents, or fillers. It’s completely free from gluten, dairy, soy, and artificial ingredients, and is suitable for vegans. The only other component is the vegetable-based capsule shell (HydroxyPropylMethylCellulose), making this one of the cleanest magnesium options available.

Trusted Manufacturing Standards

All VitaBright supplements are produced in the UK in BRC Grade AA certified facilities that follow GMP (Good Manufacturing Practice) standards. Every batch is independently tested for heavy metals, and bottles are double-sealed for safety and freshness.

Key Benefits of Magnesium Glycinate Tablets

The following health claims about the benefits of magnesium have been approved by the European Food Safety Authority (EFSA), which means there is a solid body of independent evidence that proves them:

  1. Magnesium contributes to a reduction of tiredness and fatigue

  2. Magnesium contributes to electrolyte balance

  3. Magnesium contributes to normal energy-yielding metabolism

  4. Magnesium contributes to normal functioning of the nervous system

  5. Magnesium contributes to normal muscle function

  7. Magnesium contributes to normal psychological function

  8. Magnesium contributes to the maintenance of normal bones

  9. Magnesium contributes to the maintenance of normal teeth

Best Magnesium for Deep, Restorative Sleep

Magnesium plays a key role in regulating neurotransmitters such as GABA, which promote relaxation and reduce brain activity to prepare the body for sleep. Glycine, the amino acid bonded to magnesium in these tablets, is itself known for calming the nervous system. This makes Magnesium Glycinate tablets especially effective for just about anyone experiencing sleep difficulties or nighttime restlessness. Customer testimonials frequently praise the positive impact on their sleep.

What Are ​Magnesium Glycinate Tablets Good For?

Calm and sleep

Magnesium Glycinate tablets are popular as a sleep aid as well as an energy booster. Some people take it as a calming nutrient that eases jumpiness and feelings of agitation. It helps control the balance between neurotransmitters that get us fired up and those that calm us down. 

Sleep in menopause

"I have struggled to sleep for ages due to peri menopause, regularly waking up at 4 or 5am. I started taking these tablets a few weeks ago after seeing them recommended on a Facebook group and am sleeping much better already. I have been sleeping in until after 7am for the first time in years!" - M.C.

Bones and teeth

Magnesium Glycinate is essential both to absorb Calcium, and to lay it down in your bones and teeth. People who need calcium supplements normally take Magnesium as well. 

Heart Health

As an electrolyte mineral, Magnesium conducts electricity and controls your heartbeat. You need magnesium to maintain a regular, steady heartbeat. It also supports overall cardiovascular health, and helps regulate blood pressure and the function of blood vessels.

Muscles and energy

Popular for sports nutrition and people suffering from constant tiredness, Magnesium Glycinate is essential for proper muscle function, including the contraction and relaxation of muscles. It helps regulate the flow of calcium ions, a key factor in muscle activity. It also helps convert food into energy by making ATP.

FAQs About Magnesium Glycinate Tablets

What makes these the best magnesium glycinate tablets? +

These magnesium glycinate tablets are the best choice for purity, dosage and digestion. The best magnesium for purity, they are completely free from additives and allergens, consisting of a vegetable fibre capsule containing just the active ingredient of magnesium powder. VitaBright magnesium glycinate tablets give you the exact dose of 300mg elemental magnesium that is recommended by the NHS and public health authorities. Finally, they are widely considered the best magnesium for gut health, since magnesium glycinate is one of the gentlest and best absorbed forms of magnesium supplement.

What is the benefit of magnesium glycinate? +

Magnesium glycinate is the best magnesium to support sleep, as magnesium helps the body to create the “sleep hormone” melatonin, whilst glycine supports calming neurotransmitters to deal with stress or anxiety. Magnesium glycinate tablets are a highly absorbable and gentle form of magnesium, ideal for supporting energy levels, muscle function and nervous system health, and to reduce tiredness and fatigue and help muscles relax.

Is it OK to take magnesium glycinate tablets every day? +

Yes, magnesium glycinate tablets are generally safe for daily use when taken within recommended limits. In the UK, the Nutrient Reference Value (NRV) for magnesium is 375 mg per day for adults. Provided you stay within this range - or within the safe upper intake of 400mg per day from supplements as advised by the NHS - you can take magnesium glycinate tablets every day without concern. Regular use is especially beneficial for people with ongoing stress, sleep disturbances, or physical exertion.

What is the downside of magnesium glycinate? +

While magnesium glycinate tablets are usually well-tolerated, there are some potential downsides. Some people may experience mild digestive discomfort, such as bloating or softer stools, at doses over 400mg daily. In addition, because the glycine component has a calming effect, some users report feeling drowsy after taking the tablets, something to bear in mind if taken during the day. Magnesium glycinate is also typically more expensive than other forms like magnesium oxide, reflecting its superior absorption and gentler digestion.

Who should avoid magnesium glycinate? +

Magnesium glycinate tablets should be avoided by people with severe kidney disease or impaired kidney function, as magnesium is excreted through the kidneys and can build up to unsafe levels if not properly filtered. They may also not be suitable for people already taking magnesium-based medications or antacids, or those with low blood pressure, since magnesium can cause the blood vessels to relax further. If you are pregnant, breastfeeding, or taking any prescription medication, it’s advisable to consult your GP or pharmacist before starting magnesium glycinate tablets.

At what age should I start taking magnesium glycinate tablets? +

There is no fixed age at which magnesium glycinate tablets should be started, as individual needs vary depending on diet, lifestyle, and health conditions. However, supplementation may be helpful from the teenage years onward, particularly during periods of high stress, intense physical activity, or poor sleep. Many adults begin using magnesium glycinate tablets in their 30s or 40s to support energy, mood, and muscle health, while older adults often use them to maintain bone strength and manage age-related sleep issues. For children and adolescents, only age-appropriate formulations should be used, and only under the guidance of a nutritionist or doctor.

How to know magnesium deficiency? +

Signs of magnesium deficiency include muscle cramps or twitches, persistent fatigue, poor quality sleep, low mood or anxiety, irregular heartbeat, headaches, or tingling sensations. These signs can easily be mistaken for other conditions. Your risk of magnesium deficiency is higher if you have coeliac disease or Crohn’s disease, drink excessive alcohol, or suffer from chronic stress. If you suspect a deficiency, your GP can order a blood test to check your magnesium levels.

What medication can you not take magnesium with? +

Magnesium glycinate tablets should not be taken at the same time as certain antibiotics such as tetracyclines or quinolones, as magnesium can bind to the medication and reduce its absorption. People taking bisphosphonates for osteoporosis or levothyroxine for thyroid conditions should also separate these medications from magnesium glycinate tablets by several hours. Diuretics and proton pump inhibitors (PPIs) can also influence magnesium levels. If you take any of these medications, speak to your doctor before starting magnesium supplements.

Why is magnesium glycinate popular? +

Magnesium glycinate tablets have gained popularity in the UK due to their excellent absorption, making them the best magnesium for people with sensitive stomachs. Unlike some other forms of magnesium, such as magnesium oxide or citrate, this form is much less likely to cause diarrhoea or stomach upset. The added benefit of glycine, which has calming and sleep-supportive properties, makes magnesium glycinate best for people dealing with stress, insomnia, or muscle tension.

Does magnesium glycinate require a prescription? +

Magnesium glycinate tablets do not require a prescription in the UK. They are freely available over the counter from pharmacies, health food shops and some supermarkets. Although they are safe for most people, it is still sensible to check with your GP if you are taking other medications or have a medical condition, especially if you plan to take them long term or at higher doses.

    Good quality product, fairly clean ingredients. And as I did a multi buy option were a decent price too. The caps are pretty big though prob 2cm x 0.5cm so if you struggle with swallowing large pills, something to be aware of.
