Blueberries have a low calcium content which is great for guinea pigs as too much calcium can prove fatal for them. The correct amount of calcium in their body will help them have stronger teeth and bones.

Vitamin K

Manganese found in blueberries helps guinea pigs maintain a healthy blood sugar level. This is great for guinea pigs as they tend to be more prone to diabetes and high sugar levels. It also aids Vitamin K in blood clotting and provides the body with antioxidants.

Low-calorie count

It is crucial to incorporate a low-calorie diet for your guinea pigs since they are prone to weight gain and obesity, which have many related diseases.

High fiber content

Blueberries are rich in fiber which means that they are suitable for digestion. Since a guinea pig’s diet primarily consists of water and hay, blueberries can be great for helping digest the food properly. However, if you overfeed them with too many blueberries, the high fiber count can work against your guinea pig’s digestive system and cause constipation instead.
