There are a lot of bottles on a supplement shelf. Choosing one is the harder part.
At Wellness Compounding Pharmacy of Cary, we look at the whole picture before you take anything home: what you're already taking, any duplicate ingredients, your medications, the dose, and why you're considering the supplement in the first place.
Here are a few things most people never get told:
Check for doubles. Vitamin D, zinc, iron, and B vitamins show up in multivitamins, immune blends, and sleep formulas. Three "different" bottles can quietly add up to far more than you meant to take.
Fat-soluble vitamins (A, D, E, K) can build up. More isn't always better, and extra isn't always flushed out.
Biotin can skew lab results. If you take it, tell your provider or lab before a blood draw. It can interfere with some tests, including thyroid labs.
Timing matters. Iron and calcium compete for absorption, and some supplements need to be spaced hours apart from thyroid medication. Ask before you stack them in one morning handful.
Start one thing at a time. Add a single new supplement, give it a couple of weeks, and you'll actually know whether it's helping.
Bring the bottles, not a list. Serving size, "amount per serving," and the "other ingredients" line tell a pharmacist more than a name written on a notepad.
Sometimes the conversation matters just as much as the bottle.
Taking more than one supplement or medication?
Bring your bottles in or email us, and we'll review them together.
