Apparently you can't say the word s.u.c.k.s (the ***** at the beginning of my post, haha)
For starters, you need to take at minimum 10 000 IU of D3 daily.
10 000 IU is how much your skin can generate in 10 to 15 mins of exposure to the sun (provided you expose your entire front or back with arms and legs) without sunscreen.
There are also other factors to take into account - namely height and weight.
Since D3 is fat soluble, it will be stored in the fat deposits.
People who are heavier require more Vitamin D3 so it can be processed properly.
Other than that, some people simply need more than 10 000 IU daily to experience benefits... such as 20 000 IU.
Try supplementing with 10 000 IU or 20 000 IU of D3 daily and recheck your levels after about a month or two.
I'd sooner supplement with 20 000 IU of D3 daily for a month and then reduce it to 10 000 IU daily.
Your D3 is severely deficient. I was at 19ng/mL in September and will retest my blood in a few weeks.
taking D2. That is bad. D2 depletes your body and over time you need more and more, but your levels will not be stable.
You need D3 and taken daily, not weekly or monthly. There's not enough D3 in foods to raise your levels, you need UVB rays to convert the D3 in your body. There are no UVB rays Available in the summer if your 34 degrees above the equator.
US lab range is 30-100ng/mL. You need to be above 50ng/mL. Anything below should be considered deficient.
UK should be 150-250nmoL
D and magnesium deficiency can cause depression, fatigue, anxiety, pain, brain fog, headache, eye sensitivity, etc.
You need Vitamin D3 supplements, magnesium and Vitamin K2 (as long as you aren't taking medications that would conflict with K2).
You could start at 5,000iu D3 daily for a few days to see how you feel, then work your way up to 10,000iu daily. Even when you get to corrected levels, you need to supplement daily. D3 does not stay in your body.
5,000iu is more like maintenence dose. You must retest your blood after 3 months to see where your levels are at.
The only blood test that can diagnose vitamin D deficiency is a 25-hydroxy-vitamin D (25 OH vitamin D). Unfortunately, some doctors are still ordering the wrong test, 1,25-dihydroxy-vitamin D.
Magnesium is essential, you need to take it with your D3. Take D3 with some sort of fat (like coconut oil, avocado, peanut butter, etc. it helps D3 & K2 absorb). Take D3 in morning or afternoon. Not at night. It may keep you up.
If you get enough calcium in your body & your blood test is normal, you should not take calcium supplements.
I got my newD blood test results. After taking D3 (10,000iu daily), along with magnesium and vitamin K2...
I've gone from 19.2ng/mL to 61.0ng/mL.
Taking D3 daily is the key
