  1. Sonya

    The best Magnesium on the market
    This magnesium supplement is the best I have ever used. My personal trainer recommended it to me and I would purchase through her company. But when she sold out, she provided me with the link she uses and now I order directly. I’ve been using this product for about a year now and it is a MUST have product for me as it helps give me energy and speeds up my metabolism. Food digests better and I just think my whole body works better. I ran out and was off of them for about two months, because I always got them from my trainer and had no idea I could get them through Amazon until she gave the link. I gained 5 lbs during this time. I take two capsules daily and have zero side effects. Amazing product!

    Great product highly recommended!!!
    I love this product and been taking it for almost a year now. It truly work wonders – I sleep a lot better (took care of my insomnia) and wake up feeling good with mental clarity, took care of my constipation problem. I’m 67 y.o female sort of feeling exhausted all the time and this product gave me daily dose of energy I needed. Satisfied customer here. This was recommended to me by a friend of which in turn I have recommended to other friends as well. It’s truly a great find!

    functional
    I have been taking magnesium complex supplements for a year. However, I was using a different brand and this is the first time I have tried this one. Since I started using it, I have noticed a significant reduction in muscle pain after exercise. Also, my sleep is no longer interrupted at night, and I can sleep through the night.

  4. Gerardo Lopez

    Great product, shipping takes too long
    I really like this magnesium complex brand it helps me stay asleep all night, when I don’t take it I’ll wake up a couple of times at night. I took a star because it takes forever to arrive.

  5. Kathleen KruegerKeith

    Excellent product
    I have tried other magnesium products that were way more expensive (Qualia)and this Kappa brand seems to have a great balance of magnesium that gets absorbed and transferred into my body quickly. When I stopped for a month and used the other brand, I felt stiff and slower than when I used this brand!! Excellent for people who want to take care of themselves and not just out for a quick fix!!

  6. Sue89

    Best Calcium
    This product is one of the best combination of magnesium, particularly magnesium threonate that crosses the blood brain barrier and really works to clear the glymphatic system as well as helping the brain mitochondria work much better. Overall affecting energy and less brain fog.

  7. e d derenberger

    Good and reasonable
    It’s a good supplement I use it with another magnesium supplement. To replace the mag that is affected by my heart meds

  8. annpolan

    Sleep like a baby!!!
    This stuff is the only thing I’ve found on ten years besides taking a benedryl (bad for you) that makes me sleep and have a deep sleep where you wake up w that tingly feeling. Incredible.It does make my poops loose but I’d trade that for sleep every time and my doctor agrees lol

  9. merline sularte

    my doc suggested this supplement to support my health, really effective

  10. DM

    Uno de los mejores que he probado. Recomendado al 100%

  11. Beatriz Zaragoza

    Es lo que necesitaba

  12. Luis Uriel Angulo

    Me pareció una mezcla muy buena de magnesios. Bastante eficaz aunque un poco cara. No recomiendo tomarla en la mañana o durante el día porque a mí en lo personal me indujo mucho sueño sin importar la hora, lo ideal para mí es tomarlo una hora antes de dormir.

  13. MONTSERRAT

    No sabe a nada eso es bueno
