CogniTune Vitamin D3 5000 IU with Vitamin K2 (MK7) Supplement - Premium Immune, Heart & Bone Health Capsules - Vitamin K2 D3 Complex with 5000 IU of Vitamin D3 & 90 mcg of Vitamin K2 mk7-60 Count

Great once a day vitamin D that's not too big, easy to swallow and doesn't have any odor. I can't attest to its effectiveness as of yet since I haven't had recent blood tests but they seem to be good quality. Much more cost effective than Sports Research brand

I’m just beginning to take them. Seem easy to take and easy on the stomach.

I have been vit. D deficient for years. My blood work last year measured my levels at 14 ng/mL. I tested again a few days ago and now my levels are 37 ng/mL. The reference range is 30-100 ng/mL. Ive taken the product for a couple of months I'm so happy with this product and my results! . Not only is it effective, but easy to swallow. No after tast.

Updated: I started using this supplement based on research suggesting a neuro-protective effect of vitamin D3. I hoped it would help my efforts to reverse symptoms of neurotoxin exposure.I believe it has been.Over the first six months fine motor control had improved markedly and mood stabilized somewhat.Now it has been over a year and my aphasia and short term memory is significantly improved. .This stuff is easy to take, consistent & potent.

I like the lower dosage on these pills. I'm astonished at the larger size compared with other brands that offer 2x this brand's dosage. I have trouble swallowing large objects, and this is about my size limit. If swallowing large pills is not a problem for you, this is a good choice, especially when your goal is to supplement a good diet: D3 @125mcg, K2 @90 mcg
