Premium MVA supplies daily essential nutrients, surpassing industry standards to promote superior health and performance.
Formulated for all horses, ponies and donkeys — including those pregnant, lactating, growing, elderly, in hard work, or on a high-hay diet such as horses kept on tracks and dry lots.
Premium MVA not only supplies all the necessary vitamins and minerals found in Premium NZ Horse Minerals, but also all the essential amino acids plus Pre & Pro-Biotics, for sustaining overall health, immune function, top-line and hoof health.
Key Benefits:
- High-spec and broad-spectrum: covers macro & trace minerals, all vitamins, amino acids, plus Pre & Pro-Biotics
- Amino acids derived from yeast metabolites, fortified with additional lysine, methionine & threonine to complement linseed, sunflower and other protein sources
- Delivers the high levels of Vitamin E necessary on high-hay diets
- Contains selenium (withholding time for race-horses is 24 hours)
- Contains all B vitamins, important for:
- Digestive health – helps reduce loud gut noises, FWS, and soft/runny manure
- Nerve function – supports against anxiety, hypersensitivity of the skin, staggers, loss of co-ordination/stumbling, bunny-hopping and stringhalt
- Reducing swellings and 'footiness'
- Lethargy and lack of energy
- Pre-Biotics – bioactive compounds rich in amino acids, organic acids and yeast cell wall polysaccharides (mannan, glucan and betaine) that nourish beneficial intestinal flora
- Pro-Biotics – improve nutrient absorption for better feed efficiency, extracting the most from feed for the least cost:
- Out-compete undesirable bacteria for nutrients, reducing the risk of pathogenic bacterial overgrowth
- As live yeast, stimulate immune function, response and defence, enhancing resistance to harmful bacteria and related infections
- Foster a healthy gastro-intestinal environment by promoting lactic acid-utilising bacteria, minimising the risk of acidosis
Directions for Use: 20g per 100kg liveweight daily. Use kitchen scales to weigh and mark your own replacement scoop for individual horses, or measure with a level tablespoon (approx. 20g) or heaped tablespoon (approx. 25g). Start with 1/8th of the amount and build up gradually to the full amount — only ever feed the correct amount. We recommend wearing a mask when dispensing.
Selenium is included at a rate of 0.32mg per 100g (e.g. 1.6mg for a 500kg horse). Do not use at the same time as any other product containing selenium or selenised fertiliser. Do not exceed the stated amount or frequency without veterinary advice.
Approximate guide to weights (for accurate weights, weigh an empty horse float, then again with the horse inside):
- Small pony: under 12.2hh, <300kg
- Large pony: 12.2–14.2hh, 300–400kg
- Hack: 14.2–16.2hh, 400–550kg
- Heavy hack: 16.2hh+, >550kg

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
The thermoneutral zone is the temperature range where the body can maintain its core temperature with little to no extra energy expenditure. For humans, this range is quite narrow at 21–28 °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, rugging is usually appropriate when temperatures drop below 5–10 °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.
