These include magnesium, potassium, and calcium which naturally bring down blood pressure.


  • Fennel helps with bone growth. The plant has mineral and vitamin content which ensures that the cavy develops healthy bones. For instance, minerals like calcium aid in bone health, manganese aids in bone matrix formation while zinc and iron are useful for the production and maturity of collagen.

This can be an ideal weight loss option for your cavy.


  • It helps to increase iron absorption. If there is any mineral that is mostly deficient in animals and even human beings, then it is iron. This helps in the absorption of the mineral through the use of vitamin C found in the plant.
