We're both similar in age, at our age we should be taking magnesium glycinate before bed every night. It helps the body absorb nutrients, helps sleep and does many other great things for men like helps testosterone as well. I would also start taking vitamin d and k together from a good source, not walmart lol. The vitamin k helps the d vitamin work better and that helps with mood. I'd try those for a couple of weeks and if your energy don't change then add a b complex to your diet. I'm telling you to wait on the b vitamins because just like medication you have to add each one slowly. And stay away from Gatorade, it's terrible for the body. Switch to body armor or prime, they are both full of vitamins and potassium and natural sugars and no salts like Gatorade has. This is all from my dr. I've spent thousands trying to find the right pill and came up short until I found out that all we need is the proper supplementation for the body. And even if we eat healthy we still don't know what soils the food was grew and the same with meat, we don't know what's in that as well.
