  • Need help understanding heart rhythm.

    I mostly play tennis.
    On the frontier X2 I activate this as aerobics for this workout as it seems the most similar to tennis.
    After the tennis I have a workout with 97% normal rhythm and 3% other.

    • For me the ‘main man’ for the supplement way to a healthy heart has got to be magnesium citrate. Then we have turmeric, Co Q10, Vit D and Omega 3. I would not recommend Shilajit as my heart is 90 % Sinus since stopping it.

      • I have all but Magnesium. I’ve read mixed results but I need to try for myself!. Shilajit seems to boost testosterone in me but nothing so unruly. My faves so far are the mushroom blends (reishi, lions mane, cordyceps etc.) and powdered greens. Pretty much food based things. Thanks for responding 🙂
