Excellent! The brand can be trusted

almost all of these products under this brand has good quality and ingredient that can be tested. i have been using it for many years and the dosage for me to use is 4 tablets a day. the size is easy to shallow and for people who have difficulty, this should not be a problem as it is very tiny bean.

Strong dose, easy to take

I wanted a higher dose of D3 to keep my immune system strong, and this 250 mcg version is perfect. One small pill a day and I'm done. No side effects, no weird fillers, and it gets the job done. It’s a great value for the amount of softgels you get in the bottle.

Love this product!

This is my favorite D3 supplement. I like the fact that they offer a very high dose (10.000), the softgels are small and use flax oil as a base.

Great quality, seems to really work in getting my vitamin D levels up. Love that it's suspended in organic flaxseed oil, and the 10K IU dosage. Reasonably priced. Please keep offering this product!
