    Magenisum with a wow

    I've been taking Magnesium on and off for the past 8-10 years.

    Primarily through a form of ZMA, which I've learned uses a cheaper form of magnesium.

    Within a week of using Magnesium +, I could see the difference.

    Increased vitality, restful sleep (tracked using sleep apps) and an increase in the frequency of daily morning glory.

    Superb supplement, beautifully delivered

    Having struggled a little with brain fog and fatigue, I was recommended to try a Magnesium supplement. This one from Heights has been absolutely terrific - I've noticed significantly better sleep, higher energy levels and a general sense of good health. As usual, the product design is fantastic, and the bottle is easy to pack for travel. Great stuff!

    Magnesium supplement in easy to take form

    I added Heights magnesium+ supplement, to my daily heights supplement routine of vitals + and biotic+

    Unfortunately I didn’t find the benefits to my sleep which I had hoped for.

    The supplements bottle is great and wide neck allows access to the caplets without having to shake it.

    I didn’t notice any bad aftertaste while taking them.
