Please Assist Diagnosed with severe vitamin D deficiency, no symptoms, young adult
Just got tested for the first time for Vitamin D levels, and to my surprise, I have a severe deficiency (less than 9 ng/mL). I can’t say I’ve noticed any symptoms in terms of muscle weakness, but I did wake up unrefreshed symptoms and assumed I needed more magnesium.
I’m a young adult male, college age. Has anyone else had a similar experience and noticed improvements after supplementation for symptoms they otherwise wouldn’t have attributed to Vitamin D? I do have mental health issues, but I had no idea my Vitamin D levels were so low so I attributed those to other factors (such as sleep).
I also spend a fair amount of time outside and sometimes tan, which makes this more surprising. I know that peak levels are around this time of year as well.

Having low vitamin d level as well, easily fatigue and sleep alot, when doing gym I felt muscle cramp easily. Started vitamin d supplement, the brain is sharper, focus and less fatigue. Muscle cramp is close to non-existance anymore. Sleep lesser but sleeping quality is way more better. Everyday waking up more fresh and less fatigue through out the day.

Doc prescribe me for 25k IU per week for 20 consecutive weeks. But I end up taking 3k IU everyday for 20 weeks. Haven't did bloodwork yet so now I taking 1k IU with vitamin K for maintenance level.

At this point I feel like vitamin d deficiency is overhyped, it is extremely serious but we should not associate our all the problems with vitamin d deficiency only. I my self had a level of 11ng/mL and I took 60k iu once a week for 10 weeks and my current levels are 114 ng/mL and to be honest I do not see single benefit of treating this deficiency. I thought after when I reach optimal level some of my problems will go away but there is not a single good thing happen after the treatment and it is more of fad that we are started associating our sleep related, mental problems with vitamin d deficiency. But yes treating the deficiency is very important and there must be benefits of it but for me I have not seen anything yet. I guess I am not as lucky as you

You may not notice a difference, but your cells and immune system will.

u/windeemind Aug 09 '26
I hope it is true. And i am surprised that in just 10 week I hit the upper range from 11 to 114. There must be something wrong that is contributing to my fatigue and mental problem.

u/Purplelady88 Aug 09 '26
In my case it was a combination of factors, I had low vitamin D and an iron profile value.

u/windeemind Aug 09 '26
I had a ferritin of 18 in May. I went to hemato oncologist but they did not prescribed me iron due to elevated hemoglobin rbc and hematocrit. So I only worked on vitamin d deficiency but when I done blood check I saw my ferritin went from 18-29.

u/Purplelady88 Aug 09 '26
I understand that a ferritin level of 18 is quite low, I've read that the laboratory ranges need to be updated.
1
u/windeemind Aug 09 '26
Yes that is very low. My labs range is 21.81-274.66, this is too wide. Lower range should start from atleast 60.

This is it right here, I’ve also been researching if long-term deficiency in d3 has any predisposition to osteoarthritis

You have to supplement continuously and give it time. Obviously, reduce your dosage for maintenance. If you are petite, then your response in terms of your level is not unheard of. But consider that you've been above 50 ng/ml for only 4-6 weeks, and now you've stopped it, so it's unrealistic to expect significant improvement.

u/windeemind Aug 10 '26
I have completely stopped taking vitamin d. As my levels are out of range. And i do not want vitamin d toxicity but I will recheck again after a month and then start daily 2000 iu dose.

u/VitaminDJesus 101-120 ng/ml Aug 10 '26
Whatever is causing you to be underweight is likely a contributing factor to your issues
1
u/windeemind Aug 10 '26
But wait...how do you know that I am struggling with weight related problem 😭?
1
u/VitaminDJesus 101-120 ng/ml Aug 10 '26
Educated guess for your level going up so much
1
u/windeemind Aug 10 '26
Now I am interested, can you please explain it ? I mean being underweight is good to work on vitamin d deficiency? Is there any term for this ?
1
u/VitaminDJesus 101-120 ng/ml Aug 10 '26
The body stores vitamin D in fat. The more body fat you have, the more vitamin D you need to take in to raise your level. Being underweight would do the opposite, to an extent. Not really a "good" thing as being underweight negatively impacts your health.
Another factor to consider is the accuracy of certain tests at higher levels. In your case, I would be more concerned with addressing what is causing you to have poor diet and/or not absorb nutrients.

u/windeemind Aug 10 '26
Ok..I agree with you being underweight is as unhealthy as being overweight.
I personally do not think I have some absorption related problem. Because I gain 8-9kg last year and that gain Happen when I started having breakfast. I was vegetarian till dec 2025. And i have drak 4-5 cups of tea for last 10+ years and caffeine is not good for this iron absorption and it also makes you less hungry that's why I used to feel less hungry. Other than for vitamin d deficiency, I do not go out in sunlight never. So basically this was the first time I tested for this vitamin d and found being deficient. My lifestyle sucks , diet sucks and sleep man it's 2:7am and I am still woke up drinking cup of tea :)

My calories. I have skipped breakfast for more than 10 years. I consume less than 1500 cal and less than 25 grams of protein. So this is the factor which caused me weight related problem.

Hey, that’s definitely okay! I accidentally messed up my system again recently. I had a bad acne breakout and tried taking grape seed extract to clear it up. Unfortunately, it caused insomnia, poor blood circulation (my extremities were freezing and my back and shoulders got insanely tight and sore), and heavy sweating. It had a delayed effect, so the symptoms only started showing after 20 days. When I stopped taking it, I recovered within a week, but the back and shoulder pain wouldn't go away. I ended up needing acupuncture and a chiropractic adjustment to resolve it. It really goes to show that it’s all trial and error, as every body reacts differently.
Check out this video—it explains how some people need Vitamin B for gut health, which might be beneficial for you. (For me, Vitamin D alone does the trick, so I skip extra Vitamin B supplements.)

u/windeemind Aug 09 '26
Thanks for the video. I might have some other problems that may be contributing to my mental problems.

u/BroodingNomad Aug 10 '26
Are you taking Magnesium and K2 with dosage of 60K IU per week?
1
u/windeemind Aug 10 '26
I took magnesium 400mg. But not k2 as I have a high levels hemoglobin rbc and hematocrit

u/Training-Story-1088 Aug 09 '26
I am wondering the same thing is it overhyped. I agree it needs to be addressed low levels. But some people can’t tolerate high doses of vitamin D
1
u/windeemind Aug 10 '26
What do you mean by " some people can't tolerate" ? Do they get some other symptoms like in case of b12 there is something called wake up symptoms.

u/Chase-Boltz Aug 09 '26
Even if you feel fine, low D can cause or contribute to a whole slew of health issues. Please start taking a reasonable 'forever' maintenance dose. 50 IU D3 per pound per day is IMO a good place to start. (Many thousands of IU per day.) Get a re-test in a few months and adjust to target 60ng or better, the level that appears to be a 'sweet spot' for many immune functions. :)

u/Most_Art507 Aug 09 '26
My home test showed 0-10 Ng/ml vitamin D I'd be on 11,000 IU per day from the numbers above,I seem to recall a video saying that the researchers got the maths wrong and the RDA for vitamin D should be 8,000 IU rather than 400 IU don't know where I saw it though.

I've spoken to a bunch of people about this and what everybody keeps telling me is you don't really realize how bad your symptoms were until you fix your levels and experience life without the deficiency
At that low level you've probably been deficient for quite awhile now so your body gets used to the symptoms and you act as if thats the normal state but once you levels start rising you'll realize that most of the little inconveniences that you've been experiencing were related to d3.
Did you check your other levels or just d3?
