For Horses Who Can't Finish

Adrenal Supplement for Horses

Sometimes, horses with weak adrenal glands are unable to finish an event as strong as they should.

SolidFuel® provides additional specific nutrients needed for peak adrenal function.

TIP: Offering free choice human grade salt or sea salt is important, as the adrenals need higher levels of salt than the rest of the body does.

AVOID: the brown colored commercial TM/Trace Mineral salt as it is not properly balanced for adrenal compromised horses, and it usually contains high levels of inorganic iron which is known to compromise the liver. Horses on iron supplements are often diagnosed with adrenal fatigue, and liver compromise due to iron toxicity can cause symptoms similar to adrenal fatigue.

Symptoms of Adrenal Fatigue Can Include:

  • Slow recovery after exercise, excessive and chronic muscle soreness.
  • Early onset fatigue or chronic low energy, may appear to be lazy or depressed
  • Allergies of all kinds, hives, runny eyes, runny nose, sometimes excessive gas production, heaves
  • Lack of attention span, irritability, doesn’t want to be "messed with”, grumpy
  • May consume excessive amounts of salt

If the horse is indicating low body temperatures, you can supplement Organic Iodine™ to increase basal metabolism.

You can also do a hair analysis to see if there are toxicities which might be compromising metabolism. If necessary, our Biochemist can formulate a custom supplement for any specific horse.

Consider non-legume sources of protein, such as Equine Plus® Feed, containing predigested amino acid chelated minerals, live probiotics cultures, USP Grade vitamins, water solubilized vitamins A, D and E, and essential fatty acids.

Horses with adrenal fatigue need all the nutritional help they can get. SolidFuel®, especially when combined with Equine Plus® Feed, can help horses with compromised adrenals finish strong again.


Each dose is pre-divided into 2 packets. Mix 1 packet with vanilla yogurt or Nutrient Buffer® and dose the night before the event. Then, with the 2nd packet, do the same - 3 hours before the event.

The Truth About Contamination in Equine Nutritionals

The above video shows two different samples of magnesium oxide under magnification. USP Grade (bottom-right) vs. Feed Grade (top-left). The only cause for the brown coloration is impurities including heavy metals - the pure stuff is white. The same goes for Feed Grade salt blocks. Only buy the white ones!

Maintenance Supplements

When a horse feed is pelleted or extruded, it is heated and pressurized enough to kill most or all of the probiotics shown on the label AND cooks the B vitamins into near non-existence. If you're feeding your horse a pelletized or extruded feed, you will want to supplement your feed with more/better vitamins, minerals and probiotics. The products below are maintenance supplements for top-dressing, and dosing onto pelleted or extruded feed programs. Sweet feeds are also known to be deficient in vitamins and minerals and also fail to compensate for soil deficiencies in today's world. Hay only diets suffer from similar inadequacies, and Equine Plus® maintenance supplements can help close nutritional gaps.

Equine Plus®Balancers

Equine Plus® Balancers are vitamin, mineral, probiotics blends which have higher levels of calcium and magnesium - designed specifically for balancing the high phosphorus and high protein of our Equine Plus® Feed Base.

Balancers allow you to cut feed costs by sourcing the 2 or 3 Equine Plus® Feed Base ingredients locally and mixing it yourself. The shipping cost for small packets of vitamins, mineral and probiotics packets to your door is much cheaper than 50 lb. bags of feed.
