This is the best magnesium I've ever bought (and I've bought a lot!). Particularly helps with my sleep and the whole family takes it for its many benefits. I researched until I found a pure form and a complex form so I'm happy. Customer for life I think!

Full Spectrum Magnesium
Complex With 8 forms of Magenesium
For Full-body support

Longevity Box Magnesium Complex includes a market-leading 8 forms of magnesium, each playing a critical role in different functions in your body. Our unique formula has been designed for maximum bioavailability and ultimate absorption.

The Ultimate Magnesium Complex Supplement

Magnesium essential for more than 600 different biochemical reactions in the body. Our Ultimate 8 Magnesium complex provides 8 different forms of magnesium targeting the broadest range of bodily processes to support your health.

Supports healthy stress and relaxation responses

Magnesium is an essential mineral in the body. People suffering from stress-related symptoms often have low blood levels of magnesium.

Helps with energy levels, tiredness and fatigue

Magnesium aids in the production of ATP, the body's primary energy molecule, within mitochondria. It acts as a cofactor for enzymes involved in carbohydrate, fat, and protein metabolism, facilitating the release of energy from nutrients. Additionally, magnesium helps regulate muscle function, nerve signaling, and stress hormone levels, all of which indirectly contribute to maintaining balanced energy levels.

Benefits of magnesium supplements

Our unique formula delivers the full benefits of magnesium supplements, and helps support muscle and nerve function, energy production and powers the body's natural defense against conditions such as depression, heart disease and PMS.

Muscle & Nerve Function
Optimal Energy Production
Improved Metabolism and Mood
Migraines and Pain Support

What is the suggested serving size?

We suggest you start with a 500mg serving which is two capsules. Many people take more than this as magnesium has been shown to be safe for doses up to 2 grams (2,000mg).

How can maximise absorption to get the highest strength magnesium intake?

We recommend taking our magnesium formula in the morning with food and/or a glass of water. Many people also take magnesium at night as it aids sleep.

Will Supergreens powder detoxify my body?

Longevity Stack Supergreens contains ingredients that can help with your body's detoxification and digestion. It has a probiotic blend and enzyme complex, which are two of the most important components that aid with digestion and gut health. Your liver is the one that gets rid of toxins from your body, and Enso Supergreens can help with this process.

Can I take supergreens if I am pregnant?

We advise against taking our supplement unless you have consulted your doctor and shown them the full ingredient label. The label contains all of the ingredients and the exact amounts, so your doctor can determine whether it's suitable for you.

Fiona J.

I’ve been taking this magnesium supplement for a couple of years. It appears to have helped my leg / foot cramps, asthma, reflux, and sleep. If I forget to take it for a couple of days I really notice the difference.

Julie H.

Love the packaging and the speed of delivery. Longevity are the best company for your supplement needs

Sue T.

I've been taking these for about a week and already feel the benefits... sleep better, and feel better in myself.

Suzan Z.

An important part of my evening routine, taken with dinner.

Harry H.

I am a small biz owner and I appreciate when fellow SBO's are equally good at their job! Longevity Box is just that, good at the job and the products are excellent. Just started using Magnesium 8 and am completely satisfied. Thankyou Max and Longevity Box Team

Sally c.

So far so good, easy to order, promt delivery, hopefully I will be able to tell a difference in the coming weeks

Mark L.

This is a great supplement with all the essential magnesium wrapped up neatly in a single capsule. I know that every body is different but for me this has really helped me in helping to keep blood presdure in check and my immune system. It's no doubt helping in other ways too. I have showed with this company for at least 2 years and I trust them. I like the personal touch and knowing I can ask questions which will be answered.

Adrian

It never arrived, waiting for answers from Evri

Sarah S.

Best value for money magnesium complex on the market!!

Julie S.

Best Magnesium I've tried and in 30 years, that's a lot!

Andrea H.

Love these, the only Magnesium to stop my night time cramps! Highly recommend.

Jacqueline K.

I've been taking this Magnesium for ages, as I wanted the full range of magnesium and this one offers 8 which is good. Would definitely recommend

Aftab H.

I have recently purchased it arrived very quickly but how effective it is I couldn’t comment at present as I have only been using for a few days

Faye P.

As you know M&S credit card was scammed. I advised you of new card number. Unfortunately I now have two repeat orders for Longevity 8. Please cancel the latest one, my mistake.

Marilyn T.

Delivered very quickly excellent value been taking these for a long time now and they work brilliantly I don’t buy my Magnesium from anywhere else.

Marilyn T.

I’ve been using these for a long time and find them to be the most effective having the different types of magnesium in one capsule eliminates the need for multiple doses of individual ones. Good value and service from Longevity Box.

Michael K.

Excellent help me sleep better I stopped moving around in my sleep and kicking my legs out of bed still get a few leg cramps but taking 3 a day is making me wake up in the night so back to just 2 day

Sarah H.

Paul D.

Best magnesium product available. Incudes all forms of magnesium in one pill!

Yasin T.

I use for myself and bought for my mother, brother, mother in law as well. I asvise to everybody.

Jane H.

Bought mainly to improve my sleep pattern. It has helped a lot and I feel generally much better. Very happy with the quality of this product.

Alison M.

Love this magnesium. Helps with my sleep. I take it just before bed.

Lorna D.

My husband and I have been taking these tablets for about 9 months and now wouldn't be without them. Our sleep has definitely improved, the brain fog that had started to drive me crazy had lifted and I'm not as full of aches and pains as I was. After recommending them to my Mum, she's noticed her bowel health has greatly improved and she feels better in herself. Great packaging, always a fast delivery and lovely product - what more could you ask for!

Ayyaz A.

Most probably the only full spectrum magnesium product on the market, i got an unbelievably cheap deal too, i suffer from anxiety so was reccomended these by a dr friend, i feel theyve helped with that too as im able to sleep better.

Jeannette A.

I looked around to see if I could buy cheaper brand but I trust these so will continue with them

Peter B.

I need good supplement s for my body building goals...I put my trust in things that work..these work..

louiza a.

Great product, I’ve ordered the magnesium and have been using it for two weeks. It’s too short to say if it made a change in my health but I’m quite positive about it.

Patricia D.

There are so many types of Magnesium and I was over the moon to find a company who recognise this. I have been looking for years and trying to work out which to go for. Having 8 types in one capsule is a dream come true.

marcel j.

A really good product. The Magnesium 8 makes me feel energised and that might be because I sleep better at the celater wnd of my sleep pattern when I take it. It arrives punctually and it is easy to edit the posting dates.

Kim B.

Same with these supplements as well not been taking the for a month yet so can't give a true verdict

Adekunle O.

I certainly will not fall to recommend magnesium 8 to any interested parties, for the supplement is indeed a great source of energy and calmness.

Nigel T.

Had a problem sleeping. Tried this magnesium and I sleep a hole lot better.

SLAVA B.

I love your Magnesium mix. I bought a year's worth for my brother in Bulgaria few days ago. Just wanted to suggest to add a small description of what for are all your other products! I have been buying from you for a while now and still haven't found time to read through them all to decide if I want to try something else. To an ordinary person/customer like me, the names and abbreviations of your products does not mean anything. I have to click on everything individually and read which takes time that I don't have when I am getting a new order. You are missing out sales! I could easily be tempted to add other products to my chart, but cannot be bothered to read everything. Please, add something to give us a clue what such and such products are good for - energy, brain function, bones, hair, mood... That will be very useful and will get you more business. Thank you. Best wishes, Slava

carlton w.

Great product at a fantastic price!! I intend to buy this as long as Longevity Box exist!!

KEITH W.

I was amazed to find a magnesium supplement with 8 different types of magnesium in it I had one with 5 before so this has got to be better right ! Magnesium is such an important mineral for the body with numerous different functions so I'm sure having 8 different types it's bound to be good for your body in so many different ways I do definitely notice a difference in how I feel

christine c.

It covers all the magnesium you need.

Lynda G.

This is my first buy with Longevity box and I'm very happy. I bought Ultimate 8 magnesium and I am very pleased with it. This is the only broad spectrum magnesium supplement that I have found. Thank you Longevity Box, I'll definately buy again and I have already recommended this to a friend

Mark L.

By far, this is the best magnesium supplement I have taken. And to top it all, such a great company to do business with

Marilyn T.

I have not started these yet as I had some from another company but reading the ingredients and being savvy with supplements I’m really looking forward to starting them.

Sara T.

Can feel a positive difference, more energy to get through the tasks of the day, I have long term anemia which leaves me exhausted so these are a welcome addition.

Victor N.

The most comprehensive Magnesium supplement I have found.

Jason M.

great, really helped my sleeping

Llifon J.

Happy with purchase.

Helen K.

Reccommend to mr by a doctor so that’s quite the endorsement. NMN is hard to come by in ita purest form.

Louise Houssemayne B.

Quick delivery. I take these and now my dad does as well, as feel much more energy since taking them. Had a slight problem and Max sorted straight away. Nice company. Brilliant customer service.. Now a regular subscribing customer for this product.

Adekunle O.

Kudos!!!for this idea of having all 8magnesium in one pack. It is money saving. Thanks.

Shazia K.

A great service and a great product. I am feeling much better taking the Magnesium supplements knowing that its free from all the nasties that are in most of the supplement nowadays. I bought its as a 3 months supply so it works out a bit cheaper. I also ordered some for my relatives so thank you Longetivity Box for your services

Staven S.

I started taking this several months ago to help with peri menopausal brain fog. I can't believe the difference since I started it. I take it daily before bed and it helps so much. My husband started taking it after seeing how it helped me and it has helped with reduce stress, improve sleep and overall mood is better.

David C.

An initial problem with the delivery due to error by Evri couriers was professionally dealt with by the company. Highly recommended

Katherine E.

Although large the capsules are super thin making them easy to swallow. However I did have damaged capsules in the packet which covered the pouch content in magnesium and subsequently I was short on the total in the pack and have to wash my hands after each tablet. I’ve only been taking the supplement for a short time but my sleep does appear to have improved.

Owen B.

Great to be able to take all the combinations of magnesium in one capsule

Nicola C.

Arrived on time and was good.

Margaret W.

I just opened this order a week ago although I ordered it back in November as I had to finish ones I had before. I was disappointed to find some empty capsules and a few half filled ones in the packet. I don’t think I will order again, as I do not want to be disappointed!

Nasim K.

I do find the packaging doesn’t close properly This has hampered before and I did email but no response Also the 2-3 capsules were broken they don’t look of good quality and this was the case with the Spermidine too. Bit disappointed as it’s happened more then once

Slava B.

It's my second time purchasing this product. Very happy with it. Helps me sleep better, my muscles feel better as well as sometimes I struggle with cramps. Best magnesium supplement I have come across. Highly recommended. Will order again and might try some of the other products.

Adekunle O.

Once taken I always feel calm and make me sleep better at night

Thom P.

I take my supplements seriously and am happy to keep reordering the Ultimate 8 magnesium complex after noticing improvements in both my workouts and my sleep.

James H.

To many shop bought magnesium products are unsuitable for the body. Hence why we require the various forms of magnesium. [Electrolyte]

Nicola C.

I didn't receive it and haven't had a response to my email to customer services yet.

Balwant P.

Just what I wanted, a complete all round Magnesium suppliment in easy to swallow capsules.

Amanda C.

Brilliant product! Ordered twice. We both are disabled with neurological damage. I noticed a difference with two tablets at night for restless legs that had been going on for months. Within 3 days sympoms reduced and now gone. Mood changes for the better. Husband has Parkinsons and again hes noticed a big difference in muscle spasms and jerking since taking it as a boost to other supplements as he cannot use NHS meds. The way the NHS is going and medical care in general taking responsibility for your own health is more important than ever before and companies like this are vital to support.

Paul D.

GREAT SERVICE, SUPER-HIGH QUALITY PRODUCT. DELIGHTED WITH PURCHASE AND HAVE MADE LONGEIVITY BOX THE SOLE SUPPLIER I CHOOSE FOR PROVEN LONGEVITY PRODUCTS, PAUL DEAKIN

Faye P.

Understand theimportance of magnesium & like the product. However I’m not good with ordering on line when things are complicated ie scanning etc., Obtaining this product at half the price through Amazon which is a big saving. Thank you.

Louise Houssemayne B.

Fantastic customer services. Delivery good. Packaging good. Magnesium Complex seems to be working; more energy and VaVaVoom, I think... Packaging for postage, eco, very environmentally friendly... Good ethos on natural ingredients, no fillers, and testing done..

Rachele S.

arrived on time and great care was taken with packing the product ready for posting

Sarah B.

⭐️⭐️⭐️⭐️⭐️, 10/10, 100%, Fantastic and another wonderful words. Purchased a few times now, product brilliant and service supreme. Had one issue with one of the packages and it was fixed instantly on a Sunday! Now that’s what I call service. A company that actually cares about its product and its customers. Outstanding will definitely continue to use this company.

Kate M.

I was recommended the Magnesium 8 because I struggle to find a good quality supplement. It’s great because it has varieties of magnesium, which are important during peri menopause.

manu h.

I have been looking for a magnesium supplement with 100% active ingredients, no excipients, versatile (powder), formulated for best absorption, high potency and quality, this is it. However a rigid packaging would be better to avoid capsule damage in transit.

George B.

Amazing value for money, easily the best magnesium supplement in the UK.

Julie M.

This is a fantastic complete magnesium supplement. Last time I bought it, it was loose powder (hence the free scoop), but it now seems to be available only in capsule form, so I'm not sure why a free scoop is still being provided...... Anyway, I simply split the capsules and mix the powder with water, as before. I'm very happy with the quality of this product, as well as the price and the customer service of the company. All in all, would highly recommend.

deirdre r.

Cannot say for certain that your multi magnesium is having an effect, as on a different antidepressant, which I started around the same time. Will need to wait until I have run out of mg to determine which has been helping me mentally. I am certainly much better, thankfully. Will definitely let you know if it turns out to be your mg !! Many thanks

Michelle B.

I've only recently started taking this supplement and cannot believe that prior to this I was taking overpriced capsules, this powder is far more superior

Howard K.

Best Magnesium Supplement out there. Hoping LongevityBox will make it Ultimate 9 one day by adding L-Threonate. One can dream. Also if it could be sold in large amounts for a discount.

Dave F.

Very good product 8 types of magnesium for a good price and it's pure. Cheers

Sam Williams

Better sleep Sleep has noticeably improved since taking this supplement.

A Mady
