Any recommendations.

My diet is quite bad very little fruit (hate the texture) and veg are generally same ones over and over! And lots of sweet things!

I’m 38. Looking not improve my mind, body.

I find I lack energy/motivation.

My hair grows very quick including body hair😖 but I find my finger nails slower to grow and very weak - they spilt all the time. Recently gave up smoking. Recently started going to the gym-taking it very slow as exercise isn’t something I’ve ever done properly.

So I want to add vitamins or super drink/shots for overall health.

No idea which ones and google give so many options for so many things I have no idea where to start!!

Any ideas/recommendations
