This sounds really stupid on its face, but try taking Vitamin D. While it certainly won't fix any of these problems, I found it helped my mood a bit and generally made me feel better, health-wise. And worst-case scenario, it does nothing and you're out $10.
Drink the milk, but this is one of these things where you'd have to drink like 2 gallons of milk per day to get an equivalent of one pill. Easier to just take the vitamin
Calcium is more easily and more readily absored with vitamin d, which is why it's added. The converse is also slightly true, though not to the same extent.
not fair - they don't add that here in Germany afaik.
Vitamin D is critical for the mood, but it requires sun for the body to produce it, and sun is rare in all northern areas, especially in the winter.
