I'm Currently On 25mg Losartan For High BP, Metformin For

I'm currently on 25mg losartan for High BP, Metformin for pre-diabetes, 10mg Lipitor for High cholesterol, and take 10mg Ritalin a few days a week for ADHD. I want to start working out again and I want to take BCAA's, Creatine, and Beta alanine as my pre/post workout combination. Is this safe to combine these workout supplements with my current medication regimen? Thanks in advance!
