How long do antibiotics & supplements have 2 be taken ap

[YankeesRtheBest]

Supplements and antibiotics can cancel each other out or affect the results of each other in some way when taken simultaneously. So how long do I have to wait, for example, when taking saw palmetto and Doxycycline? How do I know if supplements will affect each other like taken omega 3-6-9, zinc, and saw palmetto. Can I take them all together? Thanks. -Chris

I'm taking doxy and saw palmetto together. I don't see why they would cancel each other out. There are several websites where you can look up interactions. Just Google "drug supplement interactions" to find your favorite website. (Isn't the internet great?)
On this website I found an interaction of doxy with zinc: http://www.livingnaturally.com/common/adam/DisplayMonograph.asp?storeID=15F522D98A3A417FBE8D6 702F135785A&name=ConsLookups_InteractionsByDrug_Doxycycline
