Do Guinea Pigs Need Vitamin D?

Do Guinea Pigs Need Vitamin D?

Benefits of Vitamin D For Guinea Pigs Healthy

Benefits of Vitamin D For Guinea Pigs Healthy

Guinea pigs enjoy several benefits thanks to Vitamin D. These are better calcium absorption, higher immunity function, and Vitamin D naturally promotes bone, muscle, and heart health. 

Vitamin D allows for the small quantity absorption of calcium from the gut, which is eventually excreted by the kidneys.

Calcium Absorption is important as the kidneys of guinea pigs tend to eliminate calcium for guinea pigs, and calcium promotes healthy bones. Higher immunity function means that your guinea pig has better defenses against bacteria and infection.

Muscle and heart health are important too! There are not a lot of foods that guinea pigs can eat that can promote muscle and heart health, which makes Vitamin D an essential component for a generally healthy guinea pig.

How Do You Give Your Guinea Pig Vitamin D?

How Do You Give Your Guinea Pig Vitamin D?

There are approximately three ways in which a guinea pig can receive a good amount of Vitamin D: 

  1. Receiving direct sunlight- This is the easiest method. Direct sunlight doesn’t mean directly under the sun, guinea pigs like the sun but still have to be in shade. This is because guinea pigs can’t tolerate the heat that much, and heatstroke is possible. 

When you let your guinea pig under the sun, be sure to be vigilant and provide shade at all times, 10 minutes daily is more than enough time for guinea pigs to receive sunlight.

  1. Sun-drying food-  This is preferable, especially when it comes to hay. Hay has a lot of benefits in the guinea pig diet, and sun-drying hay gives it more advantages, such as increasing the amount of vitamin D.
  1. Incorporating Vitamin D in their diet – Providing supplements or dusting their meals with vitamin D, which is a 0.025 mg/kg diet. Some pig pellets are available in the market that offer this exact amount that is beneficial to your guinea pigs’ diet. 

What Happens If Guinea Pigs Deficiency or Overdose Vitamin D?

It is essential to know the proper Vitamin D amount that your guinea pig should receive as Vitamin D deficiency or overdose can have health risks. 

Vitamin D Deficiency In Guinea-Pigs

Having a low or a deficiency of Vitamin D is better than being overdosed. Both are dangerous, but it is easier to make amends for a deficiency in Vitamin D rather than overdose. 

A significant risk in Vitamin D Deficiency is kidney stones, as vitamin D helps with breaking down calcium, if calcium is not adequately broken down, it won’t be absorbed by the kidneys and will just be stored, creating kidney stones. 

Symptoms of Vitamin D Deficiency in Guinea Pigs are like any other symptom when they’re sick, which includes lethargy, loss of appetite, but the unique symptoms are difficulty in walking due to swollen joints, small wounds that bleed excessively, or spots that bleed under the skin.

In order to treat this in guinea pigs, one of the most efficient ways owners can do this is by giving guinea pigs 10 minutes of sunlight under a shade every day. 

You can also sun-dry their hay for 30 minutes if you give them hay, and look for pellets that contain vitamin D. Ask your local pet store for their recommendations.
