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.

    It’s been years since I have been taking this magnesium supplement and I truly feel the difference in my sleep, it aids in falling asleep. I even took a few to my mom’s back home and she suffers from insomnia- she did sleep long and well that week, it felt great being able to help her with something many take for granted. Also great value for money and quick delivery

    Good product for a reasonable price

    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.
