vitamin D and elderberry for immune support. what's everyone actually dosing
been trying to nail down a consistent immune stack and keep going back and forth on these two. from what I've read, vitamin D is pretty well supported for correcting deficiency but the "optimal" dose varies heaps depending on your baseline levels. NIH recommends 600-800 IU daily but the community consensus seems to land more around 1,000-2,000 IU for maintenance, which makes sense if you're not getting much sun. got my levels tested recently and that changed how I thought about dosing entirely. elderberry is where it gets murkier. no real standard dose, evidence is pretty thin for prevention, and product quality seems all over the place. I've seen some people swear by taking it at the first sign of something coming on rather than daily, which reckon makes more sense given the evidence gap. curious whether people here have actually tested their vitamin D levels before dialling in a dose, or just guessing based on sun exposure? and for elderberry, daily or just when you feel something coming on?
