Natural Factors Oil of Oregano Liquid 60 mL

If someone asks me what my favorite supplement is for immune support, this is probably it. Not because it's guaranteed to work better than everything else for everyone, but because oil of oregano has been one of the most consistently recommended herbal products for immune and respiratory support for a long time. I also prefer the liquid over softgels because it coats the throat on the way down instead of only dissolving later in your stomach. If your throat is one of the things bothering you, that just makes logical sense to me.

If you've ever wanted to serve an eviction notice to whatever just moved into your sinuses, quote-unquote, before it starts paying half the rent, lol, this is one of the supplements people eventually stumble across. It definitely isn't the only immune supplement I'd consider—vitamin C, zinc, probiotics, and others all have their place—but if you asked me to pick just one thing from the shelf when you feel something coming on, this is probably where I'd start.
