I’m always surprised when one who identifies as an atheist uses the phrase “I believe”. At its core, it’s a religious phrase.
Scientific studies have shown little benefit to regular intake of fish oil. Fiber, in balance with other dietary intake, has been shown to be beneficial. Vitamin D is a necessity. No peer reviewed studies show an significant benefit to oregano oil or turmeric over other similar herbs.
Interesting timing on this. My daughter just posted a quote on facebook from someone named Tim Minchen (confession: I have no idea who he his.)
“Do you know what they call alternative medicine that’s been proven to work? Medicine.”
