Can Guinea Pigs Eat Rosemary (Benefits, Risks, Serving Size & More)

Today we will talk about a herb called rosemary! Well, usually we use this herb as a spice for many meals, because of its specific and very pleasant aroma. This herb has leaves that look like needles. Rosemary has flowers too, they come in various colors; blue, purple, pink or white. Now let’s talk about whether our guinea pigs can consume this aromatic herb.

Can guinea pigs eat rosemary? Yes, guinea pigs can eat rosemary. However, this herb is very rich in calcium, and it should be fed only in moderation. High levels of calcium can cause health problems for fully grown guinea pigs. With this in mind, you should give rosemary to your furry friend only 2 times per week.

The guinea pigs really love the rosemary – as soon as they sense the scent, they go crazy for this herb! Our poor guinea pigs don’t exactly know which foods are rich in calcium, but we as their caretakers need to know this and will pay extra attention to their diet!

Sadly, all foods or herbs rich in calcium are not good for our cavies. If you want to know more details about rosemary (benefits, risks, and facts) in guinea pigs diet you should probably read the following sections.


Health Benefits of Guinea Pigs Eating Rosemary


  • Antioxidant – vitamin A in rosemary will act as a shield for the organs and the overall immunity. It removes free radicals that cause many diseases.

Nutrition Facts of Rosemary

  • High in carbs and proteins – rosemary has 21 g of carbs and 3.3g of protein. These amounts are more than enough for daily energy.

  • Thiamin – 2%. Thiamin is the B1 vitamin and it prevents diseases of the brain, muscles, nerves, intestines, stomach, and heart. It also contributes to a good flow of electrolytes in the nerves and muscles.

 

  • Vitamin B6 – 17%. The B6 produces more serotonin (happiness hormone), it reduces stress and improves sleep too.
