No change since my post on 6 Feb, zinamaria:
"I use Healthy Origins brand but I have no reason to say it is better than any other soft gelatin capsule (liquid filled cap). Making soft gelatin capsules is very specialised (few manufacturers). If the product is US/EU production I am relaxed about the brand."
I buy 5000iu/cap from iherb in California, as they ship worldwide and 5000iu is difficult to purchase/very expensive in UK. PwMS at our therapy centre (www.omstc.org
) buy together to reduce shipping costs. Also do not forget local taxes (UK VAT is 20% ! ) when comparing prices.
There are 10,000 iu softcaps available but I suggest starting with 5000iu/day for 2-3 months before getting a blood level check. I am happy with a result of 150-250 nmol/L for 25-OH VITAMIN D. UK GPs may be happier with 150. Not sure about other parts of the world.
A new product of Vit D3 in sub-lingual tabs (10,000iu/tab) are available. The theory behind this tablet is fine but I have not seen dissolution or bioavailability data for them so would not recommend them at this time. This tab contains lactose.
Liquid products are fine, if you are prepared to do the precise measuring.
Sorry for the late reply, I was on a short getaway/micro vacation.
