“Vitamin d blood levels about 70”
That’s where I am at, but it takes more than 5000 IU/day to get me there. And I’ve been there for several years now.
The liposomal C is great. So is oil of oregano.
Solves has 10,000 ui capsules. I tend to use those, taking them every other day and skipping days after beach or high sun days. I get tested a couple times a year and if I hit 100 in the blood I scale back. I didn’t get any bad illnesses this last winter. And I’m thoroughly exposed with two small kids.
