Hey TTF,
Sorry about the delay in responding. I'm on my annual fishing trip to Pelican, AK. Our house has no phone, TV or Internet access so I hike a quarter mile to the town library for WiFi access.
Thi big Chinooks (King Salmon) are hitting as are the Halibut so I'm enjoying my vacation.
There's nothing wrong with a vitamin D3 dose of 10,000 IU/day and the fastest way of building serum 25(OH)D3 is with a 50,000 IU/day loading dose for at least 12 days. That totals to 600,000 IU of vitamin D3 and that should elevate your serum 25(OH)D3 by 60 ng/mL on top of your baseline serum concentration. I'd shoot for a target 25(OH)D3 serum concentration range of 80 to 100 ng/mL
We have also had a number of CHers respond to a collection of supplements with antihistamine properties I call the Antihistamine Full Monty. It includes 3 grams/day each of Turmeric (Curcumin), Quercetin, Resveratrol and Omega-3. It also includes 250 mcg/day Selenium, 5 mg/day Melatonin (taken at bedtime) and 8 grams/day vitamin C. You can also add 500 mg.day NAC.
I buy the bulk powdered vitamin C in 1Kg bags and stir two level teaspoons in 8 oz of water then take sips all day until it's gone by bedtime. It tastes like unsweetened lemonade.
You can taper the first four supplements to 2 grams/day after a week to 10 days fully CH pain free. I'd stay at 2 grams/day on the first four supplements for at least a month. Dealer's choice on tapering further.
Tale care and please keep us posted.
V/R, Batch
