So important this time of year!
We add 3,000IUs of the CEP Vitamin E to every horse’s meal daily in the winter. It’s a much more cost effective concentrated form with 10,000IUs per included scoop (600,000IUs per bag).

The CEP Hoof Rx also has 5,000IUs Vit E per scoop with added biotin & amino acids great for hoof/hair growth and muscle recovery depending on your particular horse’s needs.

The Effects of Vitamin E on Fascia, Muscle, and Nerves - Why Deficiency Is More Common This Time of Year
Vitamin E is a critical antioxidant for the horse’s most sensitive systems. It supports muscle integrity, nervous system function, immune resilience, and recovery from work. When levels drop, the effects are often felt first in movement quality, coordination, and tissue comfort.
Because horses cannot synthesize vitamin E on their own, they rely almost entirely on fresh, green forage for intake. Seasonal changes—and certain management patterns—make deficiency far more common than many owners realize, particularly in Thoroughbreds.
Before looking at why deficiency increases this time of year, it helps to understand how low vitamin E affects the body.
Why Vitamin E Matters
Vitamin E plays a foundational role in:
Muscle health and recovery
Nervous system stability
Immune support
Performance and stamina
Protection against muscle soreness, cramping, and tying up
When vitamin E is insufficient, oxidative stress rises—placing strain on muscle fibers, fascia, and nerves.
Effects of Low Vitamin E on the Body
Effects on Muscle
Vitamin E deficiency can contribute to:
Increased muscle cell damage from oxidative stress
Slower repair of normal micro-tears
Reduced clearance of metabolic waste
Greater post-exercise soreness
Stiffness, cramping, or tying up (especially common in Thoroughbreds)
Difficulty developing or maintaining topline
Delayed recovery after routine work
Muscles fatigue faster, repair more slowly, and remain sore longer when vitamin E is low.
Effects on Fascia
Fascial tissue depends heavily on antioxidant support to maintain glide, hydration, and elasticity. Low vitamin E can lead to:
Reduced fascial glide
Thickened or “sticky” fascial layers
Increased whole-body stiffness
Compensatory tension patterns
Slower or incomplete response to bodywork
Decreased force transmission through myofascial lines
As fascial elasticity declines, many horses develop the tight, rigid feel owners often notice during winter months.
Effects on the Nervous System
Vitamin E is essential for nerve health—particularly long peripheral nerves serving the limbs, back, and hindquarters.
Deficiency may cause:
Increased nerve irritability
Muscle fasciculations (twitching)
Poor proprioception
Stumbling or uncoordinated movement
Hypersensitivity to pressure or touch
Vague neurologic signs that resemble weakness
Difficulty maintaining coordination under saddle
Even mild deficiency can make a horse feel shaky, twitchy, weak, or unbalanced.
