A really excellent deal for a 360-count bottle of 5000 iU Vitamin D3.Bought these on-sale. Normally take a minimum of 10,000 iU of Vitamin D3 but did not at all mind taking two of these tablets as they were small, white and easy to swallow.So, even if they were not the usual softgels, the small size of the tablets made it easy to take.

I find these D3 vitamins exceptionally good. Great value for the price too. Easy to digest, mild taste, good size package. As we don't see much sun here in north Finland this time of the year this is a must to boost immunity and avoid deficient. I highly recommend these!

I was subscribed to take vitamin D3 since I have PCOS and I found that this dosage for the deficiency that I have was the best package for the good quality it has and I should be taking this amount as subscribed once a week so for the amount and the size they should do until my next test it is really fast absorbent best for my bone health and immunity usually take it in the morning so I can benefit of it effect with the Sun specially that I don't go out in the sun very often is during the morning I'm working inside office it doesn't taste bad and it comes in tablets with regular not large sizeand on a side note you should always ask your doctor before taking vitamin D as it is one of the vitamins that may cause some dangerous side effects if you did not have ... MoreI was subscribed to take vitamin D3 since I have PCOS and I found that this dosage for the deficiency that I have was the best package for the good quality it has and I should be taking this amount as subscribed once a week so for the amount and the size they should do until my next test it is really fast absorbent best for my bone health and immunity usually take it in the morning so I can benefit of it effect with the Sun specially that I don't go out in the sun very often is during the morning I'm working inside office it doesn't taste bad and it comes in tablets with regular not large sizeand on a side note you should always ask your doctor before taking vitamin D as it is one of the vitamins that may cause some dangerous side effects if you did not have deficiency in itstay safe
I'm diabetic and my doctor was worried that my Vitamin D levels were too low. I am an avid cyclist and am out riding in the summer, but in winter, even if I do ride, I am covered up so she suggested I take a supplement. I knew nothing about supplements but, based on the reviews, I decided to pick these up.I take one daily and, after taking them for the past year, my doc has been very happy with my D levels for the past 4 visits. If you are looking for a supplement to help bring Vitamin D levels back up, unless you have access to sunshine all year round, these are a great choice.
Nice quality ingredients size and packageWith use its benefits for ageNice composition and scent it’s gentle on sensitive skin with frequency in use you have no concernsIt’s good calcium supplement for deficiency and bone structure improvementNice combination and tasteIt’s dosage improves immunity and its absorption is easy and wits effect is nice when you can’t use the sun
Not recommended for Vegetarians. Has Gelatin capsules. Ingredients not natural. Fairly good price point however if that is not an issue for you.Good solid packaging and good expiration date.Not much else to say you decide if this project is right for you.Recommend Paradise Herb Blend vitamin D 3 for vegetarians. Also has added herbs extra good stuff with your D. Take it all winter when there is not enough sunlight. This is a much better quality product.
For those that allergic to the sun, this is a great supplement with 400IU dosages. Aside from bone health, it provides immunity support to the body. What I like is the size of the supplement is very small too and easy to swallow. High quality as doubled sealed when I got it.
