The combination of magnesium and spirulina is potent for swift and efficient bone regeneration. I would also suggest using creatine, which helps combat mineral loss in bones and skeletal muscles.
Moreover, as mentioned earlier, maintaining a diet rich in protein, getting adequate rest, going to bed early, and ideally sleeping without interruptions are crucial. During deep sleep stages, the growth hormone is activated, aiding muscle growth and recovery. I EMPHASIZE ONCE AGAIN THAT REST IS CRUCIAL, AND IT MUST BE OF HIGH QUALITY.
Lastly, it is essential to exercise correctly. I am not only referring to physical therapy but also performing specific bodyweight exercises once your limbs are more resilient. Subsequently, you can gradually increase the intensity by incorporating light weights in exercises like squats, leg press, and calf raises. This technique is referred to as PROGRESSIVE OVERLOAD.
I trust that these three recommendations have been beneficial. Best wishes.
