First - that is incredible! There are certainly some tonic herbs and adaptogens that may support this individual. I would recommend the following:
Pearl - wonderful for bone and skin health
Eucommia - a tonic for the joints, kidneys and recovery
Cordyceps - this fungi is incredible for supporting endurance + stamina, especially wonderful for athletes
Lion's Mane - a medicinal mushroom that works to support cognitive health, immunity and longevity.
A potion can be made with all four of these or however many they want to include, (1/4-1/2 tsp. of each per one serving)
- great in coffee, tea, blended tonics with a plant milk or in kombucha or other fermented teas.
