Why do Small Pets Need Supplements and Vitamins?

While we don't doubt your small pet’s diet, we also understand that most food products for small animals don't always provide specific boosts for precise nutrition. Our range of supplements will help to prevent diseases, health complications, weight problems, and respiratory infections. In the wild, they rely on their food to brighten their feathers and live a healthy life.

The vitamins needed most by your small animal are vitamins A, D, E as many small pets can produce their own vitamin B and K without needing a top-up. The supplements are used with precise formulas to care for their skin, digestive system, respiratory system and keep their coat healthy. Vitamin A will help to support the skin and eye health as well as feathers as the immune system. Vitamin E is an antioxidant and supports the other vitamins to deliver their nutrients. Vitamin D is crucial for healthy bones while other minerals such as calcium is essential for their bone structure and maintain a healthy blood flow.


Give your small pet the care they need with Protexin Bio-Lapis, with rehydration properties this supplement will support your pet’s health and wellbeing. Easy to administrate, Protexin Bio-Lapis is a dietary supplement with vitamins A, B2, C, D3, and E, dextrose, sodium chloride, and magnesium sulphate.
