Why Choose Forageplus Monosodium Phosphate for Horses?
Phosphorus is an essential mineral that plays a critical role in your horse’s health, particularly in bone structure, cell membranes, and energy production. Forageplus monosodium phosphate for horses offers a high-purity, low-iron source of phosphorous to support your horse’s nutritional needs.
Forageplus Monosodium Phosphate for Horses contains 24% elemental phosphorous and 20% elemental sodium, providing your horse with a clean, low-iron alternative to traditional phosphate sources, which can contain excessive iron levels, often exceeding 800 ppm.
Key Benefits:
- Low iron phosphorous for horses: Our product is guaranteed to contain less than 20 ppm of iron, significantly lower than many commonly sold phosphate sources.
- High purity: Our monosodium phosphate is 99.2% pure, ensuring maximum absorption and efficacy.
- Supports bone health and energy production: Phosphorous is a structural mineral crucial for bone development, energy metabolism (ADP and ATP production), and healthy cell membranes.

Please note: Our ultra-low iron monosodium phosphate (NaH2PO4) is hygroscopic and contains no flow enhancers, so it may clump if it absorbs moisture. If clumping occurs, simply break up the clumps using the back of a spoon or rolling pin.
What is Phosphorous for Horses?
Phosphorous is an essential structural mineral found in bones and teeth, critical for your horse’s overall health. It’s involved in the production of energy molecules like ATP and ADP, which fuel every cell in your horse’s body. Phosphorus also helps form the phospholipids that maintain healthy cell membranes and plays a role in DNA and protein synthesis.
Despite its importance, forage analysis often reveals low levels of phosphorus in hay, haylage, and grass, resulting in imbalanced calcium-to-phosphorus ratios in many horses’ diets. Supplementing with monosodium phosphate for horses helps address this imbalance.
How Much Phosphorous Should I Feed My Horse?
Phosphorus requirements vary depending on your horse’s age, activity level, and stage of life:
- Maintenance: Adult horses at maintenance need a minimum of 14 grams of phosphorous per day.
- Growing, pregnant, and lactating horses require higher levels, which are often insufficient in regular forage.
- Horses in moderate to heavy work also have elevated phosphorus needs.
Forageplus monosodium phosphate provides a precise, safe supplement to ensure your horse’s phosphorous intake is optimised.
Product Features:
- Low iron content: Only less than 20 ppm of iron – ideal for horses with sensitive systems.
- High purity: 99.2% purity ensures maximum nutrient absorption.
- Essential mineral support: Helps maintain bone health, energy production, and cellular integrity.
- Supports DNA and protein synthesis for muscle growth and recovery.
- Safe for all horses: Ideal for adult, growing, pregnant, lactating, or working horses.
Ingredients:
- 100% Monosodium Phosphate (24% elemental phosphorous, 20% elemental sodium)
Feeding Guidelines:
Supplementation rates depend on your horse’s current diet and mineral levels. For a 500kg horse, feed 1 x 10ml scoop per day (approximately 11.9g, providing 2.8g of elemental phosphorous), unless a forage analysis suggests otherwise.
- Lactating, pregnant, young horses, or horses in moderate to heavy work will require higher supplementation.

How Long Does It Last?
For an average 500kg horse, one 5kg bag lasts approximately 420 days with daily feeding.

Forageplus does not advise the feeding of separate minerals unless levels have been checked through carrying out a forage analysis. The ratios of minerals are important and feeding one mineral without supplementing correct levels of another can be detrimental to horse health.
If you are uncertain of mineral levels then feeding either a Forageplus Equine Balancer or carrying out analysis of forage is wise.
