These responses are all extremely helpful, ty.  Really good reminder about omega 6.  I also know I'm low in zinc; I took the zinc test where I drank it on a spoon and couldn't taste it.  To that end, I try to eat a lot of oysters.  I do think it would be a good idea to get the blood test.  Two questions: 1-  Is there any reason you wouldn't recommend that I just buy and take a test like this as a first step? 2- I've been somewhat gluten free since ~Jan 2023 (technically organic, gluten free, soy free, light on dairy).  I eat a lot of meat, vegetables, rice -- a common breakfast for me is three eggs and a sausage link, and I can't remember the last time I had a sandwich or bread.  However, because in my mind I didn't think I had an allergy, and I more was doing gluten free to avoid artificially iron-enriched foods, I do make exceptions.  I'll eat breaded calamari.  When my Dad visits, I split mozzarella sticks with him because he loves them so much.  I'll eat the "gluten sensitive" items at a restaurant and if they asked, "is cross contamination ok?",  I always said yes.  Based on that, since I never probably fully eliminated gluten, but it was significantly reduced... is that good enough to take the blood test?  Because the pain in my side gets SO bad (really sometimes I can't function, and I absolutely thought I was dying), I am hesitant to do the gluten challenge.  Would it make sense to take the test, and if it's negative, then consider doing the challenge and seeing if I can deal with eating the bread every day? Thanks again!

For me, with osteoporosis, Celiac and more than 1 heart condition, the slower, safer route is preferable.  I'm on 5 meds per day.  Too much of anything can disturb absorption of this or that. Have a Happy Thanksgiving.  I'm gone for a few days.  

It took me 2015 to 2021 at 10,000 IU a day to get to 80 ng/ml. In 2019 I was still only 47 ng/ml The highest it has reached is 93.  Tested every 3 months.     While a one time massive dose can be used to quickly raise vitamin D levels, its effects only last three months.  Because vitamin D is stored in fat, an obese person would require more to raise blood level.     Effect of High-Dose Vitamin D Supplementation on Volumetric Bone Density and Bone Strength   The point of higher vitamin D is for the mental health and immune system requirements.  Also this study included supplementing calcium.  "Research suggests that women with low levels of vitamin D have a higher risk of breast cancer. Vitamin D may play a role in controlling normal breast cell growth and may be able to stop breast cancer cells from growing." This information is provided by Breastcancer.org. https://www.breastcancer.org/risk/risk-factors/low-vitamin-d-levels Higher vitamin D levels have been consistently associated with reduced risks of colorectal cancer https://www.cancer.gov/about-cancer/causes-prevention/risk/diet/vitamin-d-fact-sheet
