SUNDOWN NATURALS B12 500MCG GUMMIES were sent to me for free by Pinchme to test and review. The sample was enough for one serving. It was extremely enjoyable. I forgot I was eating a vitamin. There was a pleasant flavor with a clean finish. No nasty after taste or upset tummy once eaten. The gummies were not sticky or upset any dental work. I need to take vitamins daily and for years have been deficient. This was the most enjoyable experience taking B12 vitamins I have ever had. No stained teeth, upset tummy pr bad after taste. This is great and i have told my family how much I really liked taking them. It does not feel like a chore consuming this product. Thanks so much Pinchme for sending me this product that I NOW will purchase in the future.
