Why customers take it

Helps You Sleep

Magnesium is the chemical that your brain requires to initiate the actual process of falling asleep. It is also crucial for the proper regulation and production of the hormone melatonin: 'the sleep hormone'.


Magnesium Citrate is a very safe and potent natural laxative.

Magnesium Deficiencies

Around 20% of people worldwide have low levels of magnesium and deficiency is most prominent in older adults. Magnesium Citrate is among the most highly absorbable and bio-available forms of this crucial mineral, making it perfect for fortifying your diet.

Energy & Focus

Magnesium is a key electrolyte required for maintaining mental focus and aiding muscle recovery. Keeping levels topped-up is a great way to support general wellbeing for a healthier body & mind.

" levels"

"Initial response from taking magnesium is a small lift in energy levels, but it has only been 10 days, so lets see how things are after a month : ) But what a lovely company, very personal and polite with products of very high quality." - Chris E

Why it’s so good
Magnesium is an incredibly important mineral, all the cells in your body contain it and need it to function. It is crucial to processes such as energy creation, protein formation, gene maintenance, muscle movement, and nervous system regulation.

Getting enough magnesium is essential for maintaining good health, yet studies have indicated that potentially over 50% of people in the UK don't get enough in their diet.

Known as the mighty mineral, magnesium has many important uses: 

  • Your brain needs it to chemically enable normal sleep & relaxation.
  • Increasing levels can reduce stress/anxiety & might help with depression. 
  • Reduces tiredness/fatigue, treats migraines & boosts athletic performance.
  • Supports normal functioning nervous system & psychological functions.
  • Assists in regulating blood sugar levels & keeping blood pressure low.
  • Helps to retain hair pigment, slowing down the onset of greying hair.
  • Safe and effective natural laxative which can be used to treat constipation.

Although generally safe and well-tolerated, Magnesium supplementation may not be suitable for people who take certain diuretics, heart medications or antibiotics.

Always seek professional advice before introducing a new supplement to your diet.

Quick delivery. Too soon to judge effectiveness but at least I havn't died yet

Magnesium citrate

I’ve been taking the magnesium for 3 weeks, and have noticed a big difference. I’ve been suffering with spasms and restless legs and these tablets have almost cured me. I have recommended these tablets to other friends too. I have stopped taking strong pain killers which is a big relief.

John Pagdin
Effective but expensive

This product provides 118% of NRV at a cost of 16.66p per serving whereas Tesco provide 100% of NRV at a cost of 8.33p; that is half the price charged by Vitabright!! Add in the delivery charge and the cost per serving becomes 19.93p whilst Tesco's current offer of "3 for 2" brings the cost per serving down to 5.56p.

I am not connected to Tesco in any way, other than as a customer.

I have no doubt that the Vitabright product delivers what is promised but at a very high price and the Tesco product also provides 100% of NRV of Vitamin B6.

I bought one pack of Magnesium at a cost of £17.94 without much thought but that will be the last time a buy anything from Vitabright.

I very much doubt that this review will appear on the Vitabright web site.

Thanks for your feedback John, the difference in price is because Vitabright's Magnesium (Citrate) is superior to the Tesco Magnesium (Oxide).

Magnesium Citrate is among the most bioavailable forms of magnesium, meaning that it’s more easily absorbed in your digestive tract than other forms.

For this reason it is suitable for replenishing low magnesium levels. It is also reputed to have a 'calming' effect and, being a natural laxative, is sometimes used at higher doses to treat constipation.

Magnesium Oxide, the main active ingredient in Milk of Magnesia, is used primarily for short-term relief of uncomfortable digestive symptoms.

It isn’t typically used to prevent or treat magnesium deficiencies, as some studies report that it’s poorly absorbed by your digestive tract.

We always aim to provide the finest quality supplements available for the best price possible.

Jackie Smith

Absolutely love these and I know they are helping with my sleeping now during the night and just genuinely feel good since I’ve been taking it, a little under 3 weeks. Great ingredients and no nasties and my neighbour is so impressed I have just ordered some for her to try. Thank you

Judith Owen
