Nutritional supplements

Are you referring to pills--things like calcium, magnesium and so on? I can only say that I travel with many bottles of such pills--quantities sufficient for a trip of 4 months or longer--and have run into no problems. I do start out with the pills sorted into individual containers (not necessarily the original ones; I use bottles of the appropriate size irrespective of their original contents). As the trip goes on, I consolidate the remaining pills into fewer and smaller bottles. I've taken a few mid-trip flights and haven't run into anyone who showed even the slightest interest in what was in my tote bag as it went through the scanner.

Obviously, I cannot guarantee that you will have the same experience.

Same - none of our meds and supplements were examined or mentioned entering France. We have a combination of RX meds in original bottles, and OTC meds/supplements not in original containers

Thank you that gives us some peace of mind.

I put each type of medication and vitamins in a separate small zip lock bag. No one even looked at them. That was only France and Italy.

I also have several meds and supplements. I alwsys put them in a small baggie and never had a problem. I do carry a list of prescription meds on paper just in case. Never had a problem.
