Does your horse struggle with metabolic disease (EMS)? Maybe laminitis?
How would you know??

Horses with metabolic disease tend to have cresty necks and regional adiposity. This means they deposit fat in specific places, like under the mane, behind the shoulder, or above the tail head. Typical breeds are ponies, Arabians, Morgans, and Andalusians but any breed can develop the disease.
The hallmark of the disease is insulin dysregulation. They tend to have abnormally high insulin levels because their cells are insulin resistant (don't respond). Insulin is the hormone that tells cells to uptake glucose. If the cells don't respond to insulin, glucose stays in the blood and is not properly utilized. Because the body can't use glucose as energy, it tries to break down fat. Free fatty acids then course through the blood stream, overwhelming the liver, and eventually settle into random fat deposits around the body (regional adiposity).
Why is this important?
Laminitis
One of the most significant and potentially devastating outcomes of untreated EMS is laminitis
Experimentally, high blood insulin concentrations lead to laminitis
Insulin dysregulation can decrease nitric oxide production and promote vasoconstriction, decreasing blood flow to the foot.
Progression of Insulin Dysregulation
Hyperinsulinemia (abnormally high insulin levels) persists and may exacerbate other health issues
Obesity and Associated Problems
Increased overall body weight and regional fat deposits
This puts excessive strain on joints and stress on the feet
Potential liver problems due to excessive fat accumulation
When obesity develops, adipose tissues elaborate leptin and other adipokines, as well as tumor necrosis factor and other inflammatory mediators.
Quality of Life
Lethargy and reduced exercise tolerance
Chronic pain
What can you do to help?
Diet
Limit total calorie intake to promote weight loss in overweight horses
Feed a forage-based diet with low-sugar, low-starch hay
Exercise
Implement a regular exercise program to improve insulin sensitivity and promote weight loss
Start with short, low-intensity sessions and gradually increase duration and intensity
For horses recovering from laminitis, begin with hand-walking and progress slowly. Consult with a veterinarian for the best option for your horse.
Medications
Levothyroxine sodium: Accelerates weight loss and improves insulin sensitivity
Metformin: May decrease postprandial glucose and insulin concentrations
Are there any natural options?
Fenugreek
Slow glucose absorption
Improve insulin response
Reduce inflammation
Support fat digestion
Cinnamon
Normalize blood sugar levels
Enhance insulin sensitivity
Turmeric
Helps lower inflammation levels and supports gut health
Rosehip
Vitamin C and bioflavonoids to support connective tissue health
