Your good bacteria, multiplied.

Twenty-eight days, one shot a day. The bacteria that matter most, the butyrate-makers that feed your gut lining, didn't just grow. They surged.

Natural coconut fats and cognitive support

The cognitive improvements observed in the coconut kefir group may not only be linked to changes in the gut microbiome and short-chain fatty acids. Coconut naturally contains MCTs, a type of fat that can be quickly used by the body and may support brain energy metabolism.

Although MCTs were not directly measured in the product, the coconut kefir contained 1.9g of saturated fat per serving. As coconut fat naturally includes MCTs, it is possible that these natural coconut fats may have contributed to the cognitive benefits observed in the study.

A sharper, calmer mind.

Your gut talks to your brain all day long. After four weeks, Life Shot drinkers were measurably quicker, steadier and happier.
