I just thought I would add my favorite health Youtuber's advice to the conversation. One thing he stresses is how people are often deficient in things such as iodine, magnesium, and K2. He goes into his supplements at the 6 minute mark of this video.
Heat and Bandsaw BROKEN! JERKY!? Porterhouse Steaks!
(He's about 30, atheist, single, and lives in New York with his parents. Despite this I somehow trust the guy's health advice

. At times he seems very generous and helpful to people like farmers and his customers; other times he comes across as a spoiled, irresponsible kid.)
My health hack lately has been sprinkling just a little bit of Mg on some yogurt and mixing it in (careful not to inhale the dust). This way I can avoid the stomach upset that sometimes gets me when I try to take Mg in the standard 200mg and 500mg doses. Frankie has many of his supplements in dropper format (with emu oil) and that would make "micro-dosing" a lot easier.
I've been eating garlic daily for the past month or so, often raw mixed into my meal. What I've found is that it sometimes gives me a headache. Garlic and turmeric can both upset my stomach at times if used to excess.
