Sticks together

Don't know what happened to this bottle but they're all stuck together. Not hard to break apart though. And they seem to do the job.

Good, but not for me...

Good price, but... this product has a soft gel coating which has an ingredient which gives me chest pain. The same pain occurs with 1A Day men's over 50 vitamins.

Super bad odor after opening.

It was a few days before I had to open these. When I did, there was a very pungent smell. I ended up tossing them and getting some from elsewhere. It was the Vit D3. Should have gotten a zero.

Disappointing and Unusable

Arrived melted and clumped together, so that I couldn’t separate them or remove them for individual use. Very disappointing! I always store mine properly and had them less than 2 weeks before I opened the bottle to a clumped mess. Will not purchase these again from Sam’s Club!

Great brand because USP verified

These are really good vitamins for deficiency. They are USP verified. They also cost 75 less then nature made. Thank you sams club. I needed 5000 iu instead got these because the calcium I take Also has vitamin d. I take a total of 5000 iu for severe deficiency due to chronic pancreatitis and Exocrine pancreatic insufficiency. I will definitely purchase again and again.

Fixed the stickiness of the gels.

We take Vitamin D3 daily. Early on the gels get a bit sticky, so takes longer to put each one in our weekly pill containers, plus also stick in each daily group of pills. My husband suggested I sprinkle a bit of powdered sugar in the bottle, making each gel easy to distribute and take daily.

Not so great

I need to take 5,000 IU of Vitamin D a day. Usually Sam’s has this. For some reason they have been out and I couldn’t wait any longer so I bought this and I use two pills. I don’t care for these pills as much. They are soft gels, but they are softer than the 5,000 dose. So they stick to each other and they are hard to get out of the bottle but also they stick in my pill case. Hopefully Sam’s Club brings back the 5,000!
