Bryan,
I would try loading vitamin D3 at 50,000 IU/day for a week just to build your 25(OH)D3 reserves higher and in the process, help get the CH beast back under control. Taking vitamin D3 is particularly important to help prevent viral infections like COVID-19. It's also best to start taking at least 50 mg/day zinc picolinate, 400 mg/day Quercetin and 1 gram of vitamin C three times a day. These are the immune boosting supplements that work the best.
The nutritional supplements illustrated in the photo below provide a safe (No Harms) and proven prophylaxis for most viral infections. If you're already taking the anti-inflammatory regimen, all you need to do is add the 50 mg/day zinc picolinate, 400-800 mg/day Quercetin and 3 grams/day liposomal vitamin C (1 gram every 3 hours).
Zinc: The need for supplementation increases with age
Take care,
V/R, Batch.
