My doc thought D3 at 5,000 IU/day might cause kidney stones. I did some reading of the research on this and it appears to be a slight risk, but I cut back to 3,000 IU/day a couple weeks ago. At 5,000, my VitD, 25-Hydroxy Tot serum was 41 ng/mL. The lab report says “There is no known benefit of values >50 ng/mL.”
I was taking fish oil capsules for a while and got really obnoxious fish burps. Ugh. My doc later said the research really didn’t support Omega 3 supplementation with fish oil, so I discontinued that supplement. It’s interesting it popped up here in conjunction with Vit D3 to combat autoimmune diseases in older people (that’s me!).
I just tested and my blood level D3 was 52ng/ml.

I’m taking OTC EPA only (DHA removed) Omega 3. Poor mans RX Vescepa which is FDA approved to lower heart attacks and strokes for those also with high trigs and on a statin. Zero doubts it has the same benefits for those not on stains or have high trigs. Its just how the study was set up for FDA approval. A sub set study shows that Vescepa works by actually reducing preexisting plaque in the arteries after prolonged use. DHA may be good for some maladies but it works against EPA for heart health.
“The lab report says “There is no known benefit of values >50 ng/mL.””
those lab reports say all kinds of things, in particular, they simply regurgitate the predominate dogma of the day (e.g., FDA, CDC, et. al.) lots of stuff in lab reports is still disputed, AND so-called “normal” levels can actually be different for a given test from labs owned by different corporations ...
there’s quite a bit of high-quality, published research that shows less morbidity and mortality from covid for values >50 ... in fact, high D3 levels is considered very desirable by groups such as the FLCCC and others that actually TREAT covid with safe and effective therapeutics ...
also, high-quality fish oil that hasn’t turned rancid has less chance of burps ...
a really good one is:

[you should test every new batch by poking a capsule with a pin and tasting the oil to make sure it isn’t rancid]
The lab report says “There is no known benefit of values >50 ng/mL.”
Just hospitalization and/or death.

There are other studies that claim vitamin D3 and calcium supplementation leads to high calcium levels in the urine, which is thought to be a precursor to stone formation, however that isn't always the case:

Further studies have shown high dose vitamin C supplementation correlated to kidney stone formation, but I'm tired of digging up links. I'm sure we could toss study after study back and forth that proves/dis-proves one another's study/citation assertions.
I'm not sure what to believe anymore since I'm waiting to get scheduled for a second surgery for kidney stones. I stopped taking a multivitamin just before the first surgery (ESWL). I figured the calcium in the multivitamin was part of the problem.
