The gals are taking D3 and magnesium. Mr Hutchinson and I both use iherb.com as their shipping costs to Europe are very low. It won't be a problem for you to order from them from Canada either. I've already heard from other Canadians on this forum that they've had no troubles. You might want to check if there are any limits on how much you can order to ensure that you don't have to pay any import duties or extra taxes. That should come up on the site when you enter in the country you want the goods shipped to.
The best D3 on offer at iherb.com is this one:
At only $15 US for basically more than a year's supply, this is great value. I have been using them for about a year now, too, and can recommend them. I haven't had my D3 levels tested since I started using it, but will be getting them tested in about a month.
I don't know how far north you are in Canada, but most people in the same latitude as Northern Europe would need to take D3 for most of the year, apart from the months of April to October, when you can get the real thing from sunshine. If you can't get any real sun - half an hour max at mid-day would do the trick, say on your lunch-break - then take a capsule that day.
Recommendations vary on how much to take. I used to take one a day, but have gone down to just one every other day. Anything between 2K and 10K per day is recommended and can be safely taken.
To get the best synergistic effects, especially in terms of mood and happiness (see the posts by the happy ladies above!!!), then you take a good quality magnesium supplement with D3. These are the ones that Mr Hutchinson and I recommend:
I have used this one and have had good results with it:
Some of the good effects I have noticed were: lower back pain gone, edginess gone, leg cramps mostly gone (but I need to take the stuff regularly, as I seem to be still pretty low). New positive things: calmer, more balanced, practically no PMS any more, more energy, less moody and less prone to flying off the handle over nothing, happier, more able to take things in my stride.
This is another variety of chelated magnesium glycinate which Hutchinson recommends. I may try it just for the sake of scientific comparison
but so far I have stuck to the Dr's Best brand because it is cheaper.
I was taking 400mg per day, but when my new bottle arrives, I may take more for a while to see if I get better results. I like what the ladies above are saying, but they are taking more than me, so maybe I need more to get the same effect!!!
If you want more information about dosing etc, just post again!
Hope this helps,
