Great product, based on actually raising my Vitamin D levels (25-hydroxy). After I bought these I saw the “how much do you need to raise your D” formula by the Vitamin D council and it was clear that 7,000 IU would be more appropriate for me, so I then also bought the similarly-formulated Country-Life 1,000 IU softgel product and take two of those at the same time as one of these. Based on the studies, I try to take my D with a meal every day, especially one containing fat. For reasons I won’t go into, I retested my 25-hydroxy D at one month instead of the intended three months, and my level has already gone up from 20 to 40! Based on previously seeing my levels go *down* after 1 month on 1,000 IU of a dry D product taken at night, I was pleasantly surprised at how well it is working. I can’t say I feel any different (at least not yet). And VERY IMPORTANTLY, I am monitoring very closely for any possible D-induced increase in my serum calcium, as having elevated (or even near-elevated) serum calcium generally confers MUCH more serious health risks than having below-range D. So far so good on that count, though, but since my serum calcium’s in the high-9’s already I need to be careful. Once I’m where I want to be on the D (ideally about 50 or 60), my “dilemma” will be figuring out how much to take ongoing to sustain that level instead of either continuing to increase or dropping back down.

The softgels are a lot smaller than in the other alternatives on iherb - I don't know if that's relevant. I've been using these for 2 months and so far haven't noticed any difference. It is summer (vitamin d from the sun) so I probably won't know if they're any different until winter.

Same as other D3, and good value too.

We reived both bottles after 13 days in Holland. Everything was well and we are using them since. Thanks, until the next time.

Sorry I can't help. This is one of several products/medicines I am taking in an attempt to discourage tumours from growing further. I have no way of knowing therefore if Vit D3 is good for me but will continue!

This product worked just as good as more the expensive ones and it shipped very fast. Thank you.

I have just started using these, they are easy to swallow, no complaints so far.

Would prefer higher dosages, though.
