I have vit d diffency so I take 2 drops in my morning smoothie. It has zero taste at least when mixed with things. I have no suggestion to improve something that seems to work well as is. That said it's way more pricey compared to the small tablets.

I was using the pills and they are great snd small but to encourage my Husband to start taking it once in awhile in the winter I got these he likes and I am happy

In the winter I use this to boost my vitamin D as I get sluggish and tired without being in the sun and outdoors being active with the kids. This helps boost my energy
