It Works

Posted by Reviewer2517781 on May 20, 2011

I started using this to boost my vit. D levels along with a vitamin K blend that I also take and I got my D levels to double in a few months' time. Very happy with this product because the blood tests actually proved it was working!

Very disappointing

I'm not sure why it is, but Jarrow D3 seems to be ineffective. If anything, it leaves my feeling slightly worse. Tried them twice now with the same result. This is in contrast to the consistent sense of wellbeing I get when using two other brands at this dose.

right potency, right price

My MD told me to start taking 5000 IU every day only it's not so easy to find. Iherb and Jarrow, as usual, came through. Nice small capsule too. My husband and I both take it.

forget the flu

Posted by Reviewer3184172 on Jan 04, 2015

I take 10,000 IU a day during the winter. My doctor checks my vitamin D levels and they are in range! Imagine how deficient I'd be if I didn't supplement. In the summer I drop to 5,000 a day. I never get the flu shot -- or the flu. This may be the one supplement I couldn't live without and Jarrow is an excellent brand. If you add anthing, add D3 and trust Jarrow. It's a life-saver. Just be sure and get your blood checked to be safe!

This 5000 IU is what my DO told me to use. After several months my vit D came up and has stayed up. Easy to swallow.

I have been using this D3 for years. I find it works well, does it's job. Tried others they really didn't raise my D3 levels like Jarrow does.

Is this good for diabetes??

Posted by 5716071121513494453 on May 25, 2016

I love that these are tiny gel caps. I started taking these because my mother has osteoarthritis and I am trying to take care of my bones before it gets to that point. I also take Iodoral because my thyroid functions has always been low but never low enough for medication. For the past 2 years my A1C has been going up and up until I was pre-diabetic. I recently had a blood test and was told my glucose levels were NORMAL. I have only been taking them for 3 weeks. I don't know if these are the reason my levels are now normal but I have not changed anything else.

Good for everyone

Tiny softgels, easy to take. Vitamin D deficiency is very common. Even when you are enjoying the sun your skin can't make Vitamin D if you are using sunblock. I would recommend Vitamin D supplement for everyone. Feel free to visit my page (click on my name) for more reviews.

Great Vit-D supplement

Posted by Reviewer3307818 on Aug 31, 2010

Most people need at least this much Vit-D. Very small softgel.
