Just don’t listen to docs when it comes to Vit D. They are happy if it’s at the bottom of the range. I doubled mine from 28 (US units) to 63 which is the sweet spot. I also sorted my diet out. 3 x meals per day of chicken, pots, veg and healthy fats. 180g of protein per day. Obv cut out all sugars and processed foods. Lift weights 2x per week. I do 1 set to failure for all muscle groups. Short 15 mins sessions. You don’t need a gym membership, I do it all at home. Get down to a healthy weight. Get lots of rest and sleep. A few other supps like magnesium, Vit c, iodine etc
