FAQs



What are sleep and relaxation supplements?

Sleep and relaxation supplements are formulated products designed to support your evening routine and nightly rest. Common ingredients include magnesium, which contributes to the reduction of tiredness and fatigue2 and normal psychological function1, alongside other carefully selected nutrients. They're available in various formats including tablets, capsules, and gummies to suit different preferences.


How do magnesium supplements support sleep and relaxation?

Magnesium is an essential mineral involved in over 300 biochemical processes in the body. It contributes to normal functioning of the nervous system4, normal muscle function3, and normal psychological function1. These roles make magnesium a popular choice for those prioritising recovery and relaxation as part of their daily routine.


Magnesium also contributes to electrolyte balance5 and normal energy-yielding metabolism6, supporting the body's natural processes during both activity and rest.


When should I take sleep and relaxation supplements?

Most people take these supplements in the evening, typically 30 minutes to an hour before bed. This timing allows them to fit naturally into your wind-down routine. Consistency is key — taking them at roughly the same time each night can help establish a rhythm that works for your schedule.


You can take them with or without food, depending on the specific product and your personal preference. Check individual product labels for any specific timing recommendations.


What's the difference between magnesium bisglycinate, citrate, and malate?

These are different forms of magnesium, each bound to different compounds. Magnesium bisglycinate is chelated to the amino acid glycine and is known for being gentle on the digestive system. Magnesium citrate is bound to citric acid, while magnesium malate is bound to malic acid. All forms contribute to the same authorised magnesium benefits.


The Tri-Magnesium Capsules combine all three forms to provide a comprehensive magnesium supplement in a single convenient product.


Can I take sleep supplements alongside other vitamins and minerals?

Sleep and relaxation supplements can typically be taken as part of a broader supplement routine. Many people combine magnesium with other nutrients like vitamin D, B vitamins, or multivitamins. The Sleep Capsules already contain a blend of carefully selected ingredients formulated to work together.


As with any supplement routine, it's sensible to review the total intake of individual nutrients to avoid exceeding recommended amounts.


Are these products suitable for athletes and active individuals?

Yes, these supplements are particularly popular among athletes and active individuals. Magnesium contributes to normal muscle function3 and the reduction of tiredness and fatigue2, making it valued by those balancing training demands with recovery needs. Many athletes prioritise magnesium as part of their daily routine.


The convenient formats — from tablets to gummies — make it easy to maintain consistency whether you're at home, travelling for competition, or managing a busy training schedule.


What format should I choose — tablets, capsules, or gummies?

The choice comes down to personal preference. Tablets and capsules offer straightforward, no-fuss dosing and are easy to take with water. Gummies provide a more enjoyable experience and don't require water, making them ideal for those who prefer a tastier option or have difficulty swallowing tablets.


All formats deliver the same nutritional benefits — it's simply about what fits best into your routine and preferences.


How much magnesium do I need daily?

The UK Nutrient Reference Value for magnesium is 375mg per day for adults. Individual needs can vary based on factors like activity level, diet, and lifestyle. Many magnesium supplements provide a significant portion of this daily requirement in a convenient single serving.


Checking the product label will show you exactly how much magnesium each serving provides and what percentage of the NRV that represents.
