For short periods

Posted by 5196307679141928132 on Jun 08, 2014

I used it because I had information that high doses of D3 were recommended for short periods until 4 weeks. Seems that this one is of high quality.

Great Product

1 capsule per week maintains my Vitamin D at levels over 80n mol/l, but some people will need 2 per week so get your doctor to check you level, Ideal level from most research 80 to 160. My family have used them for over 1 year.

Too early.

Sorry, but as I have only just started to take these, it's a bit too early to tell or to make comment on. Will get back to you in the near future. Thanks.

Potent stuff

Posted by Reviewer2025838 on Feb 25, 2011

My doctor had told me to take 5,000 IU's a day to get my D levels up (they tested at 24 with a normal range of 30-70). I thought I would just take one of these once a week and it would be good enough. For me, it's just way too strong a dose. In fact, taking 5,000 IU's is too much. I'm scaling back to 800 IU's and letting my D3 levels build back up slowly. I like the Twinlab D3 because it's water dispersed. Thorne is a great brand--I buy a lot of their other products.
