Zahler - Advanced Vitamin D3 50000 IU capsules (120 Count) Kosher Vegetarian Friendly Vitamin D for Immune Support, Bone, Teeth & Muscle Health - Weekly D3 Vitamin Supplement- Easy Swallow Vitamin D3.

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.

No side affects and easy to use

I was taking the prescription brand but now my insurance won’t cover it and I would be paying $30 for four pills a month. Spoke to my Dr showed him this brand which is equivalent to my prescription and he agreed with me. I have had no side effects and easy to swallow. After being on them for 3 months I’ll be having blood work to see how my levels are. I’ll let you know!

This is the best product ever!

Seems of good quality but time will tell if it does the job

I think these work, haven't taken a blood test to check

I've been a user of other brands such as biotech and nivigen for years because they are dry (non fat based) cholecalciferol d3. Gastric bypass RNY distal RNY and DS and even SADI should be taking one or two a day from the go but sadly this information isn't terribly well known. My specialty is professionally GI malabsorption and I have it myself after some unfortunate medical malpractice issues and can attest to Zahler d3 being quality. While my d level hasn't improved as dramatically due to my conditions, I've managed to stay off another feeding tube and keep osteoporosis at bay so it's doing its job. Make sure to take with the right calcium to unlock the Mechanism of action. My d level went from an 11 to 22 in 3 months with 8 daily pills or 400,000 IU daily which is significant improvement for short bowel syndrome. Nivigen is the brand used at the big red pharmacies at $1.50 a pill, these are better for a tenth of the price. Not sure what's going on with the price- currently at $40 double its usual but again still worth it.

I suffered from joint pains (mainly hands, shoulders and chest) for several months making it difficult to comfortably perform my duties at work and even at home. I bought a can opener (yes, crazy for a seemingly healthy 38 year old). I am into fitness a lot and this made it literally impossible to do what I love: push-ups (my shoulders couldn't bear the pain), use of ab wheel and carry weights (dropped from a total of 60lb to 25lb). At least I could run on good days. A pre-employment physical I had done earlier showed that I had vit D deficiency but I ignored it; I was wrong. I realized that that was the cause of my joint pains. I bought this product and started taking it once weekly. It's been almost 5 months now and ALL the pain in my hands and shoulders is gone. I have resumed physical activity as before and I feel in great shape. So yes, I highly recommend this product. price is unbeatable and yes it works.

Good product and moderate price. Recommended.

I’ve been using it once a week for 3 weeks now. Haven’t noticed anything yet but pill is easy to swollen and I have my blood test in 3 more weeks will update

Perfect one .

great item

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.
