Your system can also be running short on nutrients due to diet or lifestyle choices. Maybe you're missing out on enough magnesium in your diet, affecting your sleep and anxiety levels. Perhaps you aren't getting enough sun or eating enough salmon, and your vitamin D levels are running low. An OTC vitamin could supplement that.
Even if you are leading a healthy lifestyle and eating right, your system could benefit from a boost! Supplemental vitamins and minerals can help replace what medications have removed. Have a conversation with your pharmacist about your side effects, and your pharmacist can help suggest solutions as well as work with your doctor to find potential changes to your current medication regimen.
