Highly effective
I typically take Vitamin D in large amounts to get enhanced benefits for bone strength and immune strength. this formulation includes vitamin K which enhances the absorption of calcium in your system.
These are high strength capsules with 5000 units of D in a small and easy to swallow capsule.
As with any vitamin product it takes some time for the benefits to be felt however with these products they seem to have better effectiveness than my previous brand and I find myself not having to take as much to get the full benefit.
The price is good for a premium product and the developers seem to have put a lot of thought into the formulation.
I am fussy about my supplements and always buy the best that I can find.
The known benefits of Vitamin D are many and it is essential for your good health. Yes, you can get slightly cheaper D capsules in Costco but that is false economy, as overall it will take more to get the same benefit.
I love this company and all their products are top-shelf.
Don't shortchange your health.
I will buy these again.

Dentist recomended
So i ordered this a while back but i wanted to use up my last bottle of D3 vitamin. I have used this smarter nutrition brand for just under a week, so it is a bit difficult to say whether this product is any better than any other brand.
But so far so good. I have no problems swallowing these pills nor any digestive problems whatsoever or any after taste.
AS far as a D3 supplement, you really feel no difference and i bring this up because i am being truly honest about this product. I started taking vitamin D3 products because my dentist, who is also a nutrionist, advised me to take this supplent for stronger bones. Also to be honest, I am 67 years young and i need all the help i can get..LOL.
I take many other nutritional products and this brand of Smart seems to have everything i need for a daily regimen. So No need to buy supplements from more than 1 supplier.
And, yes i guess i would recommend this brand to others who like to buy what they need from 1 supplier.
