8 Types of Magnesium For The Price of 1!


Despite being found in many of the foods we eat, most people don’t consume enough magnesium in their diet. It can be found in everything from leafy greens and nuts to seeds and beans and plays a vital role in our body. 

The current issue with many magnesium products in the market is they don’t offer the full package. In the market, there are currently at least 11 different magnesium types that can be taken as a supplement, each with its own benefits. Now we don’t know about you, but 11 supplements sounds a little too much. This is why we have a solution. 

Magnesium contributes to electrolyte balance, normal energy-yielding metabolism, functioning of the nervous system, muscle function,  protein synthesis and psychological function, as well as the maintenance of normal bones and teeth.

Our ultra pure magnesium powder offers more types of advanced magnesium than any alternative on the market. Using a cutting edge complex formula, we offer nearly 3x more diversity than triple magnesium complex alternatives!

The 8 types of magnesium in our formula are:

  • Magnesium Chelate 
  • Magnesium Citrate
  • Magnesium Bisglycinate
  • Magnesium Malate
  • Magnesium Aspartate
  • Magnesium Taurate
  • Magnesium L-Threonate
  • Magnesium Glycinate


With 8 types of magnesium in a single supplement, there’s no other product in the market that can bring you so much variety!

As part of the Longevity Box tribe, we’ll make sure you always magnesium when you need it. You can buy our Pure Ultimate 8 Magnesium as a single package, or you can sign up for monthly subscriptions to make sure you’re always in stock. 


Dosage and Guidelines:

When taking magnesium for the first time you should start with 0.5 gram(s) per day. This can be taken with a drink at any time during the day. 

The upper dose range is 1 gram per day. 


Directions for Regular Use:

The easiest way to take magnesium is with a drink as part of a meal. It can be consumed during any time for the day, though consistent times are recommended for the best effect. 

    Purity Certificates

    At Longevity Box we are committed to sourcing the highest purity longevity supplements on the market. Our products are pharmaceutical grade and independently verified for quality and purity by renowned third party test laboratories.

    We work with well established suppliers that have regular factory inspections and are certified with CGMP and ISO to ensure the highest standards are consistently met. We have third party independent laboratories test every batch of product that is produced and display on our website the latest tests for the batch that is currently in stock.


    Please see below the latest third party independent test certificates for our current batch of Longevity supplements.

    Independent laboratory testing is critical to ensure that the product is at least 99% pure and contains no dangerous levels of heavy metals or micro-organisms. If an online retailer is not providing test results then there is no certainty that there products is pure or even the product that they claim it to be and whether it’s safe for human consumption. Establishing purity and authenticity is critical when consuming small molecule longevity supplements like NMN. It is clear that the market has many websites selling impure or fake NMN.

    Every batch of Longevity Box supplements is independently verified to have a purity of at least 99%, with no dangerous levels of heavy metals or micro-organisms. You can find the latest certifications for each product here: 

    NMN purity certificates 
    Resveratrol purity certificates
    NR purity certificates
    Ca-AKG purity certificates

    Apigenin purity certificates

    We are committed to your long term health and will always ensure our products are of the highest purity and quality.
