A Guide to Vitamins and Minerals for Pets


Vitamins and minerals are important for pets' health and nutrition just as they are for ours. Ideally, they are obtained from fresh food but that can be hard when life is so busy. Therefore many pet owners are giving their pets supplements to ensure they get the sufficient levels of vitamins and minerals required to support optimal health.

Supplements are an easy solution as long as you are choosing the right one. They should contain all-natural ingredients from plant and animal sources and be free from synthetic ingredients and 'fillers'. PetWell's all-natural supplements contain active human-grade ingredients in the correct ratio to work together for maximum benefit and balance.

Health conditions relating to joint and mobility issues, digestive problems, as well as heart and organ health can all be aided with the right supplement. Using high-quality, all-natural supplements specifically designed to support these conditions are an excellent way of ensuring your pet has everything they need without the risk of overdosing.

We've created this guide to vitamins and minerals for pets that outlines what benefit each nutrient provides and in which food you can find them.

Minerals play an important role in aiding cell function, but it doesn’t stop there. Some minerals have a more focused impact on your pet's general health. Calcium, phosphorus, and magnesium keep the bones in good shape.

The balance of acid and fluid in your dog's body is maintained by potassium, sodium, and chloride. Magnesium and potassium work with calcium to cause muscular contraction and are essential for the health of the nervous system.
