If you searched for “Equine Challenge Hoof Propel NSC,” you’re probably trying to determine whether Hoof Propel™ is appropriate for an insulin resistant horse, an easy keeper, or a horse with a history of laminitis. It’s an excellent question—and one that deserves a clear explanation. Understanding how NSC (Non-Structural Carbohydrates) is measured can help horse owners make informed decisions about their horse’s nutritional program.
Is Hoof Propel Low In Sugar & Starch?
Yes, Hoof Propel is fed in a concentrated one-ounce serving, so the amount of sugars and starches consumed is very small compared with the horse’s forage intake, with an NSC less than 5%.
Why Different Websites Report Different NSC Values
Horse owners are often surprised to find different NSC numbers online for the same supplement.
The reason is simple: unless the finished product has been analyzed in a laboratory, an exact NSC value cannot be calculated from the ingredient list alone.
Some websites estimate NSC using ingredient databases or nutritional models. While these estimates can provide general information, they are not laboratory analyses of the finished product and may differ from the actual composition of a supplement.
While third-party websites may publish estimated values, those estimates were not provided or verified by Equine Challenge Supplements and should not be interpreted as laboratory-tested results.
Hoof Propel™ is fed at just one ounce per day, making the contribution of sugars and starches to the overall diet very small compared with the horse’s daily forage intake.
Natural ingredients—including flaxseed, yeast cultures, and plant-derived ingredients—can vary from one harvest to another due to growing conditions, processing methods, and other natural factors. Because of this variation, estimated values should be viewed as approximations rather than verified laboratory results.
Horse owners sometimes find different NSC numbers for the same supplement across different websites.
This happens because some websites use nutritional modeling or ingredient assumptions rather than laboratory testing of the finished product.
While these estimates may be based on general data, they do not always reflect the actual tested composition of a supplement.
What Is NSC In Horse Nutrition?
NSC stands for Non-Structural Carbohydrates, which include:
- Sugars
- Starches
These carbohydrates are primarily found in:
- Grass and hay
- Grains
- Commercial feeds
- Treats and high-starch supplements
For horses with metabolic concerns, managing NSC intake typically focuses on the total diet, especially forage, which makes up the majority of daily intake.
Can You Calculate The NSC Of A Supplement?
In most cases, no.
An exact NSC value cannot be accurately calculated from an ingredient list or guaranteed analysis alone.
This is because:
- Ingredient sources naturally vary
- Processing methods affect carbohydrate levels
- Plant-based ingredients fluctuate by harvest and growing conditions
- NSC requires laboratory testing of the finished product, not just individual ingredients
For this reason, published NSC values from third-party sources should be viewed as estimates rather than verified laboratory results, unless they are backed by direct testing.
Why Serving Size Matters
Another important factor in NSC discussions is how much of a supplement is actually fed daily.
Hoof Propel™ is fed at a concentrated serving of just 1 ounce per day.
Even when ingredients contain naturally occurring carbohydrates, the actual amount consumed in this serving size is very small compared to:
- 15–25+ pounds of hay per day
- Pasture intake
- Grain or concentrate feeds
For this reason, most equine nutritionists evaluate NSC in the context of the entire diet, not isolated supplements.
The Bottom Line
When searching for “Equine Challenge Hoof Propel NSC,” the most important takeaway is this:
- NSC is best evaluated across the entire diet, not a single supplement
- Hoof Propel™ is fed in a very small daily amount (1 oz)
- Third-party NSC values are estimates unless laboratory tested
- Forage contributes far more to NSC intake than supplements
Hoof health is influenced by overall nutrition, balance of key minerals, and long-term consistency—not one isolated ingredient or number.

Frequently Asked Questions
Hoof Propel™ is fed in a concentrated one-ounce serving, so the amount of sugars and starches consumed is very small compared with the horse’s forage intake, with an NSC less than 5%.
Many horse owners use Hoof Propel™ as part of a carefully managed nutritional program for easy keepers and horses with metabolic concerns. Because every horse is different, dietary decisions should be made in consultation with your veterinarian or equine nutritionist.
Yes, Hoof Propel has an NSC of less than 5%. Many horse owners use Hoof Propel as part of a broader nutritional program for horses that are:
- Easy keepers
- Insulin resistant
- Diagnosed with EMS
- Managing PPID (Cushing’s disease)
- Prone to laminitis
However, every horse is different, and dietary decisions should always consider the entire feeding program, especially forage quality and quantity.
We recommend working with your veterinarian or equine nutritionist when managing metabolic conditions.
Hoof Propel™ is formulated with nutrients commonly associated with hoof health, including:
- Biotin
- Lysine
- Methionine
- Magnesium
- Zinc
- Copper
