Vitamin E is one of the hardest-working nutrients in your pet's body — keeping their coat shiny, their muscles strong, and their immune system robust.
Vitamin E is your pet’s built-in bodyguard, defending them from wear and tear accumulated during exercise, play and normal life.
Anytime your pet is doing anything – running, digesting food, recovering from illness – their body is producing free radicals: tiny, unstable molecules that damage the cells in their body.
That’s where Vitamin E comes in. It’s a natural antioxidant, and its whole job is to protect your pet’s cells by neutralizing those free radicals before they can do damage, keeping your pet’s cells strong and intact.
How it works
Every single cell in your pet’s body is wrapped in a thin, fatty layer – a bit like a protective skin.
Free radicals love fat, so they attack that layer first. However, Vitamin E lives inside those same fatty layers and acts as a shield. It keeps cells healthy, stable and able to keep on doing what they’re supposed to do.
To give you a quick visual: think of the free radicals as the Pac-Man ghosts, and Vitamin E as Pac-Man.

Vitamin E delivers top-to-tail benefits
Skin and coat
Vitamin E locks moisture into the skin and keeps the skin barrier strong. Pets that are low in Vitamin E can develop dry, flaky skin and a dull coat.
Immunity
Vitamin E keeps immune cells resilient and effective, so your pet’s better able to fight off illness.
Muscles
If you’ve seen your cat leaping to the top of their cat tree, or your dog bounding round the park, you’ll know muscles get a lot of everyday wear and tear. Vitamin E protects that muscle tissue, so your pet can better recover from day-to-day activity.
Digestion
The digestive process creates free radicals, which can increase digestive discomfort. If your pet has poor diet or GI inflammation, that can produce even more free radicals. Vitamin E breaks that cycle by protecting cells from damage.
The nervous system
Nerve tissue is rich in fat, which makes it vulnerable to damage by those free radicals we mentioned earlier. Vitamin E is essential for keeping the nervous system communicating with the rest of the body – so your pet can be alert, playful and fully engaged with their Pet Loyalists.
