Magnesium helps with all sorts of functions, from looking after your bones and teeth to supporting your nervous system and helping to reduce tiredness and fatigue.1
Our in-house nutritionist Madalena Vieira Costa explains that "a lot of people with magnesium deficiencies experience tiredness, stress or muscle cramps.” Although it’s always best to get your nutrition through your diet, it's not possible for everyone.
Discover eight of our best-selling magnesium products, with Madalena’s expert input.
What’s the best magnesium product for you?
It really depends on how you’d like to take it and what you’re using it for. To help get you started, here are some of our favourites...
If you’re looking to give your daily wellness routine a powerful upgrade, these Magic Magnesium Glycinate tablets might just be your new favourite go-to. This thoughtfully crafted supplement blends highly bioavailable magnesium bisglycinate with essential B vitamins, vitamin D and a unique mix of herbal extracts, all designed to support your energy.
Magnesium plays a key role in helping your muscles and nerves function smoothly and keeps your energy levels in check. It’s also known to help reduce tiredness and fatigue – something we could all use a little help with, especially on busy days.
But this formula doesn’t stop there. It includes vitamin B1 to support a healthy heart, along with pantothenic acid, which is known to support your mental performance. And let’s not forget the impressive herbal plant extracts: French maritime pine bark and long pepper.
Together Health’s Natural Marine Magnesium offers a complete, natural form of this essential mineral, sourced directly from the mineral-rich waters of the Dead Sea. Known for its remarkable potential benefits and supporting minerals, it provides all five naturally occurring types of magnesium: oxide, hydroxide, sulphate, carbonate and chloride.
Rather than relying on synthetic processes, Together Health uses simple methods – evaporating and purifying the seawater to gently extract magnesium.
Each capsule contains 188mg of high-quality magnesium, supporting everything from energy levels to muscle function. It’s suitable for people who follow a plant-based diet, easy to take and kind to your body (and the planet).
BetterYou Magnesium Flakes offer an easy and affordable way to enjoy the calming benefits of magnesium chloride at home. Whether added to a warm bath or used for a soothing foot soak, these concentrated flakes provide a deeply relaxing experience.
Made with magnesium chloride, they dissolve effortlessly in warm water, making it simple to unwind after a long day. Just 20 minutes in the bath or a quick foot soak can leave you feeling restored, relaxed and ready to take on whatever’s next.
Don’t let the fruity flavour fool you – this refreshing pomegranate and rhubarb drink is more than just a tasty treat. Each can is packed with 180mg of magnesium, covering nearly half of your recommended daily intake, along with a unique blend of magnesium bisglycinate, citrate, Irish sea minerals, natural nitrates and essential B vitamins.
Expertly formulated to support energy and electrolyte balance, it’s a simple, effective and delicious way to top up your magnesium and support everyday wellbeing, one sip at a time.
BetterYou’s Magnesium Joint Body Spray combines the power of magnesium with glucosamine, menthol and eucalyptus oils to offer a refreshing, topical support. Every 10 sprays contains 100mg of magnesium and 50mg of glucosamine, which has been designed to be applied topically on skin.
The cooling sensation from menthol and eucalyptus helps ease tension and keeps you feeling refreshed. It’s simple to use – just spray it on after a shower and massage gently into the skin. This vegan-approved spray is a convenient way to support your body whenever you need it.
Our Calcium Plus Magnesium and Vitamin D tablets bring together three key nutrients that work hand in hand to support healthy bones and muscles. Calcium and magnesium are a perfect pair, helping your muscles contract and relax while maintaining healthy bones.2 Magnesium also plays a role in reducing tiredness and fatigue, supporting your energy-yielding metabolism.3
With added vitamin D (especially important in the UK where sunshine can be scarce for most of the year) this combination ensures your body gets the support it needs.4 Each easy-to-swallow capsule delivers 250mg of magnesium and 500mg of calcium, making it a simple, effective daily support suitable for veggies.
BetterYou’s Magnesium Sleep Body Spray blends pure Zechstein magnesium with calming essential oils like lavender, chamomile, bergamot and clary sage to help you unwind and enjoy a restful night’s sleep. Just a few sprays before bed gently relax your muscles and soothe your senses, making it easier to drift off naturally.
Each 10-spray dose offers 130mg of magnesium. It’s perfect for adults and children ages 13 years and above. While it’s a great addition to your bedtime routine, it’s best to avoid it during pregnancy due to the clary sage content – so always check with your midwife or GP if you’re expecting.
This travel-ready spray is an easy way to bring calm and comfort wherever you go.
How much magnesium do we need a day?
The NHS recommends 300mg a day for men and 270mg a day for women aged 19-64.5 But many of us don’t get enough – in fact, 20% of women fall short.6
You can get magnesium from green veg, nuts, dairy products and more. If you’re still struggling, a magnesium supplement could be the answer.
What is the best way to take magnesium?
There are many ways to take magnesium, so it's really up to you. However if you have a deficiency, then it's best to take orally as a supplement.
Whether you prefer to stir powder into your smoothie or soak in the bath, it's also important to remember which are safe to swallow and which are only ever applied topically.
- magnesium tablets: usually the most cost-effective way to take magnesium
- magnesium spray: sprays are absorbed into the bloodstream more quickly than tablets or capsules. They’re also handy on the go
- magnesium capsules: a great alternative to tablets for those who still want to take magnesium this way but don’t like the texture
- magnesium drinks: a tasty alternative to tablets, magnesium drinks are a great way to stay topped up
- magnesium effervescent tablets: soluble in water, so they’re another great alternative to tablets you swallow
- magnesium powder: often contain added ingredients and can be added to water to make a drink
- magnesium cream: applied to aching muscles to help ease soreness
- magnesium bath flakes: perfect if you love a soak
- magnesium gel: magnesium gel can help soothe muscles at the source
It’s worth noting that magnesium you apply to the skin or bathe in will work differently to types you take by mouth.
With creams and gels, “the muscles absorb it and you're going to feel the benefits of the anti-inflammatory properties directly in the area that you applied it to. Instead of it being spread out through the whole body, it would be a lot more of a direct impact," says Madalena.
The final say
From muscle function to bones, teeth and energy levels, magnesium’s one to keep on your list. Alongside your diet, you can choose from sprays, tablets, drinks, effervescent tablets and more to top up.
