Essentials Formula 1 with Selenium for Horses

Affordable equine minerals and horse supplements are available at Power Star Nutrition. This supplement contains selenium.

This is a super equine vitamin, mineral, amino acid, and hoof supplement all rolled into one which promotes a shiny coat, healthy hooves, and topline. This formula has high levels of Biotin, plus amino acids,  L-Lysine and DL-Methionine and L-Threonine.

Specifically formulated for NZ conditions and Soil types

It provides essential nutrients lacking in many feed crops, pastures, and soil.

It has no added iron, making it the perfect supplement for horses and ponies grazing on NZ pasture and drinking bore water with high iron content. Essentials Formula 1 is one of the best copper and zinc supplements for horses on the market.

It is designed for horses and ponies not receiving premix feeds, or below recommended daily rate. It can also be fed in situations when a very small amount of premix feed is fed, and daily recommended vitamin and mineral requirements are not being met.

The level of selenium will generally keep the average horse or pony at current selenium levels unless the soil is fertilized with selenium prills or the pasture is high in selenium. Getting your horse’s blood tested for selenium yearly is highly recommended.

Essentials Formula 1, Selenium Free is recommended when:

  • Your horse or pony receives a blood test showing high selenium levels but still requires a vitamin and mineral supplement to maintain health with no selenium added.
  • Is being supplemented with selenium from your veterinarian or other supplements?
  • Grazing on a property that has high levels of selenium in the soil and pasture.

Equine Minerals: The Importance of Zinc, Copper, and an Iron-Free Formulation

New Zealand’s pasture, hay, and feed crops have high iron levels which can reduce the availability of zinc and copper. The most common mineral imbalance in hay is too much iron combined with low zinc and copper levels. A high iron concentration can interfere with both zinc and copper absorption, making already low levels of these minerals even less available to your horse.

Until recently, the veterinary industry has viewed iron toxicity in equines mainly as an acute condition—the result of overdosing on iron-containing supplements. However, researchers have found that equines exposed to high iron levels in water, grass, or hay over a prolonged period can accumulate the mineral in their livers, resulting in chronic iron overload.

Black-skinned horses which include greys need more copper and zinc than others. Bays and chestnuts will look washed out with lighter colors than normal coats, and the blacks will have a definite reddish look.

Horses need copper in their diets to properly utilize iron and to develop healthy connective tissue. It is also important for horses with allergies. It can lower the concentration of histamine in the body. Copper also helps to keep the central nervous system running correctly.

In adult horses, a deficiency of copper and zinc in the diet may cause limb deformities, thinning of the bones, swelling of the joints, blood vessel weakness, connective tissue weakness, saggy skin, and a lowered immune system.  Copper is the main mineral for the body to produce T cells. It is also important for bone integrity, heart health, skin pigmentation, and to prevent premature graying.

Horses showing signs of low iron levels can be supplemented according to veterinary instructions. When copper deficiency occurs, iron levels fall too short, and anemia can develop.

Avoid Added Iron

Avoid vitamin and mineral supplements for horses that contain added iron as an ingredient.

Horses typically obtain more than enough iron from their diet, and excess intake could have negative health consequences.

Products with added iron will have one of the following ingredients listed on the label:

  • iron oxide
  • ferrous furmate
  • ferrous sulfate
  • ferrous gluconate


It does not contain Magnesium. Magnesium requirements are individual and a different magnesium product like Pazture Guarde or Pazture Mag can be added separately.

NZ Natural Zeolite

Essentials Formula 1 and 2 contain NZ natural Zeolite in the form of Optimate, an ACVM-registered toxin binder. This is a highly bioavailable natural form of silica that supports bone and connective tissue health. Performance horses and senior horses may especially benefit from Zeolite.

Are you looking for a way to improve your horse’s hoof health?

Essentials Formula contains high levels of  Biotin. Each 22.5-gram scoop contains 15mg of biotin. This sulphur-containing B vitamin is essential for healthy hoof growth and plays a role in hoof horn quality and hoof wall strength. Biotin supplementation has become increasingly popular in recent years, as it can help correct biotin deficiencies, improve hoof hardness, and promote overall hoof health.


🐎 Essential for healthy hoof growth: Biotin is an essential coenzyme in the metabolism of carbohydrates, protein and fat, enabling support of growth, performance work and reproduction.

💪 Improves hoof hardness: Biotin is used in supplements to improve the quality of the horse’s hoof and is also beneficial to the coat.

🦄 Promotes overall hoof health: By using a biotin supplement in your horse’s feed, it can help promote strong, healthy hoof horn growth.

How it works:

Biotin should be fed to horses needing to improve poor hoof horn and develop healthy hooves. It acts as an essential coenzyme in the metabolism of carbohydrates, protein, and fat and so enables support of growth, performance work, and reproduction. Biotin is particularly important for normal thyroid and adrenal gland function.

Carol Vernal – Whangarei – August 2022

Hi Rachel, look at Bella from your Essentials Formula 1 with Selenium. She is looking amazing, especially since it’s Winter.


Kiri Parrish Auckland –

Highly recommend this product. I recently had a young pony come into my care that had rain scald and needed a boost in condition. Two months of use and she is not only looking much better and healthier but feeling it as well. Essentials Formula 1 has really helped get this young pony back on track

Hana Bognuda – Wanganui – July 2016










Dee’s hooves have been really bad lately, with cracks and he also has a skin condition. Rachel advised him to start on the Essentials Formula 1.

His feet have improved heaps, in a short time – no more big cracks and they are not so brittle. It also helped with the skin on his back legs. He had a mud rash all year round and nothing worked for it, but this seems to be getting rid of it!

Elise Lett – Rotorua – February 18

This is a client of mine, Billy is a TB and had huge bacterial/fungal infections in his offside forefoot. We started him on the Essentials Formula 1, vitamins, and minerals. We treated the infection with hydrogen peroxide and copper sulfate crystals. Within 10 weeks it was mostly grown out and his hoof horn quality had improved immensely!

Billy has made massive changes in the health of his hooves since starting on the Essentials Formula 1, five months ago. Thanks for such a great product. Billy’s owner has also been more proactive in his hoof care. The right minerals can make a huge difference in hoof health, combined with good trimming and an owner proactive in hoof hygiene.


Kylie Parrish – Auckland- August 16

Essentials is a vitamin, mineral, amino acid, and hoof supplement. Specially formulated for New Zealand’s environment. It provides essential nutrients lacking in many feed crops, pastures, and soil. Encourages a shiny coat, healthy hooves, and topline. Essentials Formula 1 is amazing. Over the last few winters, my poor pony Holly was extremely prone to rain scald, and mud fever. The rain scald was raw and covered in blood. It was itchy and extremely sore to the touch.

We had our hoof trimmer out today and we realized that Holly has NO mud fever or rain scald this winter even though it is wetter than normal in Auckland. Both Mork and Mika do have mud fever on their white socks, the only difference is that Holly gets Essentials, and the other two don’t. They have been grazing at the same place, same mud, same cover, same hay, same hard feed, and same supplements, except for Essentials.
The Quick Hair helped the hair grow back, without any white hairs or scarring. The Essentials has helped this from happening this winter. It provides the essential nutrients missing in the soil, especially during the months of July and August when it is wet and muddy. Zinc and Copper levels become very low and levels in some feeds and supplements don’t meet the nutritional requirements of the horse.

  1. Rachel

    Essentials formula 1 with selenium is the best mineral supplement I have fed my horses and ponies. I have a couple that have struggled with hoof growth and skin conditions, especially during winter. This is no longer a problem.

  2. K Parrish

    Essentials have been brilliant, my paddocks have been literally water and mud, Essentials have really helped with the healing of having to be in these conditions. I recommend this product and the service is helpful and informative. thank you
