It really works!
I waited to write this review since I was taking this supplement since March and would have blood work done in June at my annual physical. Every year for as far back as I can remember my vitamin D levels have always been deficient. Every year the doctor writes a prescription for vitamin D for a short period of time and the cycle starts all over again. This year, for the first time in years my vitamin D level was within normal limits! This supplement really works and I won't stop taking it once a week. I can't be out in the sun long enough to get the natural vitamin D benefits and this tiny capsule does the trick. This is a great supplement and is highly recommended! I do even notice it since it's so small and easy to swallow.

Very Good Product
I am a physician, I have used third product for my family and for my patients. Extremely good product due to its size, lack of taste and swallowing issues and also the efficacy.

Love it
I was pretty excited when I ordered the vitamin D3, I've been taking a vitamin D3 pill for sometime and thought I would try a different brand. Sometimes, you notice little things about the different brands of vitamins, I don’t know why that is. Anyway, the vitamin doesn't have a taste, which is a relief because I always have a hard time taking pills that have a taste or even a slight taste to it. This vitamin was very easy to swallow, with a full glass of water to help your body digest it. I did notice a couple of small things while I started taking this pill. I have noticed that my energy is slowly coming back, I'm sure after taking it for a month straight that I will notice more energy. I don't feel sluggish as much, but it could also be due to changing my eating habits and incorporating the vitamin D3. I'm sure after taking this vitamin for two months, you will notice a small difference with your health. I haven't been taking this pill for a full month yet but I am curious to see what changes I will feel.

THIS WORKS!!! WOW
I have been struggling with low vitamin D levels for close to three years. I live in an area where our winters are long and gloomy. I always run borderline low or really low. I've consistently taken first 2000 IU daily and then a 5000 IU daily from Jarrow. Over a year and neither of these did much of anything. I believe my last check 2 months ago my D was 24. I was so excited to discover that 50,000 could be purchased OTC. The only thing that has ever worked was prescription D3, 50,000 IU, but my new doctor has been annoyingly reluctant to prescribe them, worried about toxicity. Well, I did my own research and found peer-reviewed published scientific studies that determined 50,000 even twice a week for one month was safe and effective. This statement is NOT medical advice, so please do your own research and discuss with your own doctor before supplementing. Anyway, I took the Zahler weekly for one month, had my levels tested prior to starting (27) and a couple of days ago, and learned my D is now 97!!! Unbelievable!!! It's never been that high. Now that I'm close to the upper end of the range (100), I'm going to stop taking the Zahler for now and take a little break from D altogether, before switching to a lower strength daily to maintain. I highly recommend this product to anyone who struggles with low vitamin D levels and will always keep this in my arsenal. IT WORKS!!!

We usually get 10,000 iu for D3 but doctor suggested to get 50,000 iu., thankfully I found it cheaper on amazon and the capsule is really small in size and the quantity is good to go for months.
