A quality blend of chelated calcium with essential co-factors — a daily nutritional supplement, proudly made in New Zealand.
Additional calcium is required for:
- Pregnant mares, to build the skeleton (and other tissues) of the unborn foal
- Lactating mares, especially until the foal is about 3 months old — young foals take virtually all their nutrition from their mother's milk, so if she doesn't get enough calcium from her diet, it's drawn out of her bones to meet the foal's needs. This is detrimental to her long-term health and can mean the foal doesn't get everything he needs to be strong and healthy
- Horses working hard, who lose calcium through sweat
- Horses grazing grasses high in oxalates (especially kikuyu in New Zealand), which bind up calcium and make it unavailable — the organic calcium in XtraCal is already bound, so it can't be bound by oxalates and remains available to the horse
Pregnant and lactating mares that are also grazing oxalate grasses are especially vulnerable to calcium deficiency.
Directions for Use: One tablespoon ≈ 20g. E.g. 5 x 5g = 25g for a 500kg horse.

- Recreational & competition horses – 5g

FAQ
All your questions, answered.
A quick guide to matching your horse's needs to the right supplement — and when to feed it.
1. Daily Foundation - Overall Health & Longevity
Feed year-roundPick one. Both contain selenium - feed the daily amount all year round.
Minerals, Vitamins & Amino Acids
The complete option — supplies every vitamin and mineral your horse needs, plus the amino acids that support overall health, immunity, top-line, and hoof quality.
Vitamins and minerals including 100% organic selenium, copper, zinc, chromium, sulphur and manganese. A good fit for horses, ponies and donkeys who don't need the extra amino acid support in Premium MVA.
A non-selenium option is also available.
2. For Grass-Related Issues
Adjust seasonallyHow much you need will vary with the season, the weather, and how much grass is around.
Helps balance the high potassium levels found in green grass. Dissolve in the water you use to wet the feed, and build up gradually following the back-label directions. Especially useful when you can't control your horse's access to grass.
For flare-ups. While you're building up GrazeEzy, feed SOS at the high dose to get more serious issues under control. Once your horse is back to normal, gradually taper the amount down and keep some on hand for next time.
An advanced formula for horses showing:
- Muscle tightness, anxiety or excitability
- Skin sensitivity, girthiness, twitching, ear-shyness or head-flicking
- Gait issues - loss of co-ordination, staggering, or dragging toes
- Hallucinating, spookiness, claustrophobia, aggressiveness, light sensitivity, puffiness or swelling
Supports nerve and muscle function for top performance. For some horses, even the small dose makes a real difference to their demeanour when grass is a challenge.
3. Add When Required
As neededExtra support for specific life stages or conditions — add alongside your daily foundation supplement.
Pure amino acids with a prebiotic - a potassium-free source of quality protein that gives any horse's overall health a boost. Good for:
- Horses recovering from a nutritional setback
- Pregnant and lactating mares, and weaned foals
- Growing, elderly, and Cushing's horses and ponies
Supplies additional calcium plus the co-factors needed to get it to the skeleton. Good for pregnant and lactating mares, growing and elderly horses, or horses grazing kikuyu grass.
Toxin-binding support from Mycofix Plus 5.E, helping manage the effects of mycotoxins in hard feed. Also provides:
- Calming benefits from chelated magnesium and Vitamin B1
- Tissue-strengthening support from silica
Not sure what rug your horse needs right now? Our free Horse Rug Forecaster checks your local weather and tells you what rug weight your horse needs today, tonight and over the next 3 days. It works anywhere in New Zealand and adjusts for clipped horses and horses that feel the cold.
The thermoneutral zone is the temperature range where the body can maintain its core temperature with little to no extra energy expenditure. Humans need it much warmer, at around 25–30 °C, but for horses it’s much broader at 5–25 °C.
This difference means we should avoid rugging horses based on how cold we feel. Over-rugging can lead to serious health issues, including metabolic problems and thermoregulatory dysfunction.
Tips for Choosing a Winter Rug Weight
-
Clipped horses may need a heavier gram fill to stay comfortable.
-
Remember: horses warm themselves more easily than they cool down under a rug. If unsure, choose a lighter rug.
-
Check your horse regularly to make sure they are neither too hot nor too cold.
-
Consider your horse’s age and natural ability to stay warm.
-
As a general guide, a healthy unclipped horse with shelter usually doesn't need a winter rug until it feels colder than about 5 °C, but always adjust for your horse’s individual needs.
-
Always ensure rugs are waterproof. A wet rug is worse than no rug at all.
This is an indicative guide only. Always take into account factors such as wind chill, your horse’s age, weight, and condition. For advice based on your local forecast, try the Horse Rug Forecaster.
