rummikub Yes, it is good if you can reach a pretty good blood level fairly quickly, which you would do , if you took , 20,000 IU every 3 or 4 days. When you reach your desired level, it would be best to have a daily dose, of less. The aim would be to maintain a good blood level, at a reasonably constant level, throughout the year. Individual responses tend to vary quite a bit. A regular test , maybe in spring will help you discover what is best for you. Make sure your prescription is for D3 , not D2,( which is less effective )

Your level of 61 is at the bottom end of the "normal" range, at least in my NHS area lab. ( 50 - 167 ) . It is midsummer now, so I expect you have been making some vit D since late april, before that time it is very likely that your level would have been lower. Probably dropping from its peak , in early October last year. Could your symptoms be due to low Vit D ? , well yes they could. Is it advisable to get your level up ?, in my mind, yes, particularly since you are describing symptoms which might be caused by a lower level than your body requires.
It is safe and easy to do that.
Your doctor is right in saying that your level is normal, i.e. many many people would be measured at that level in this country at this time of year. That does not mean that your level is optimal, or that all those other peoples level is optimal. Your level is about half that enjoyed by your human ancestors , for millions of years.
Don't forget, Vitamin D is an enabler, it enables your cells to function normally, to create products, proteins, signals to other cells, etc etc. You also need all the other required inputs to your cells for this to happen, in other words your diet. You should be consuming plenty of veg, fruit etc, with a wide range of vitamins and minerals. Don't forget at least some dark green leafy veg, which is most important, as the chlorophyll in them contains magnesium, a known co-factor of vit d.
Is vitamin D guaranteed to cure your problems , well no, but at least you will be giving your body a fighting chance !
With your level now , of 61, if you took 2000 IU per day you could expect to reach about 110 in 3 months. However, in winter if you took an extra 1000 IU ( total 3000 IU ) , that would compensate for the lack of sunlight. Also extra 1000 IU on top would not be unreasonable , because you are trying to help a current health problem and not simply trying to maintain a staus quo with regard to your health.
Hope this is helpful. Good luck
