Suggested use to start - 1/16 tsp per 30 lbs - once a day.

You can increase to or even more:

Store in a cool dry place away from humidity, heat, and direct light. Do not use in animals with bleeding disorders or diabetes, unless directed by a veterinarian. Do not use in pregnant or lactating animals.

Helpful Tip: Mushrooms are not that tasty for some dogs, so I recommend mixing them with yogurt, kefir, bone broth, organic coconut oil, or even butter (Dr. Ihor Basko recommendation) to help with the taste.
