As flu season approaches, many people look for ways to support their immune system naturally. One nutrient that has received significant research attention for its role in immune function is Vitamin D3.
Research suggests that a large portion of the population may have suboptimal Vitamin D levels — even in sunny climates. Vitamin D3 functions more like a prohormone than a traditional vitamin, with receptor sites found in nearly every cell of the body. Healthy Vitamin D levels have been associated with robust immune function, bone health, mood support, and metabolic wellness.
When taking higher doses of Vitamin D3, it is important to pair it with Vitamin K2 (MK-7). Vitamin K2 helps direct calcium to the bones rather than soft tissues, supporting both bone density and cardiovascular wellness. A minimum of 180 mcg of Vitamin K2 (MK-7) is commonly recommended alongside Vitamin D3 supplementation.
A note on Vitamin D3 supplementation: Optimal dosing varies by individual and should be guided by blood testing. We recommend consulting your healthcare provider to determine the right level for you.
Regarding flu vaccines: Vaccination decisions are personal and should be made in consultation with your healthcare provider based on your individual health history and risk factors.

Repy to Erica:
Insomnia and muscle twitching should not be side effects of vitamin D3. I suspect that you are not taking vitamin D2
which is synthetic and gotten with a prescription.
Terrible insomnia is very suggestive of excess adrenaline, which can also cause muscle twitching. However, I am at a loss trying to connect this to vitamin D. On the positive side, lowering adrenaline levels is certainly doable.

What would cause me to get terrible insomnia while taking vitamin d? Also, it makes all of my muscles twitch
Why do you say that “vitamin D is not a fat-soluble vitamin”? I understand that it’s really not a vitamin at all, rather it is a hormone, but I’m unaware of evidence indicating that it’s not fat-soluble. Indeed, if it’s not fat soluble, why would it be that the places we find it stored in nature are in oily fish, egg yolks, and the fat of pastured pork?
