Our BC2A® formula is made from a premium ratio of branched chain amino acids which lead the way for supporting decreases in lactic acid production which promote muscle building and repair, protect lean muscle mass, and delays onset of muscle fatigue.

BC2A®, is a branched chain amino acid paste in a tube dispenser formulated to enhance skeletal muscle adaptation to exercise training. By supplementing the horse 30-60 minutes prior to exercise with a tube of BC2A®, it provides an easily absorbed properly balanced ratio of premium circulating branched chain amino acids to support the demands of working muscles.

Our product stems from years of research, field testing, and keeping our eye on the highest quality ingredients with the most stringent manufacturing practices.
We use our products on our own horses every day proving our commitment to providing your horses with the very best formula.

4 Pack- 4 tubes @ 19.95 each
10 Pack-10 tubes @ 17.95 each
20 Pack-20 tubes @ 17.95 each
30 Pack-30 tubes @ 17.95 each
40 Pack-40 tubes @ 15.95 each




Absorption rate data provides specific guidelines for giving BC2A® branched chain amino acid formula.  Peak levels where attained within 30-60 minutes.

BC2A® L-crystalline predigested form is easily absorbed rather than digested. Thus, a circulating reservoir of correct ratios of branched chains are readily available to the muscles within 30-60 minutes of giving BC2A®.    

  • Weekly Training and Stepping up for Performance Events: Give one entire tube, 30-60 minutes before each workout for reduced lactic acid and heart rate benefits. For young horses heading to the track for the first time, or returning horses following layoff, give one entire tube, 30-60 minutes before work & within 30-60 minutes following work for 4 consecutive days.
  • Muscle Tightness: Can give one entire tube at the signs of muscle tightness. Wait one hour and provide an additional tube to continue providing circulating branched chain amino acids.
  • Trailering: Give one entire tube of BC2A®, one hour before loading. Can be repeated on arrival. 
  • Weekend Warriors: With infrequent training or intermittent performance demands, can provide one entire tube 30-60 minutes before work.

With BC2A® … Muscle Performance is built into every tube!

How is lactic acid produced by the equine athlete?

Muscles obtain energy by metabolizing glucose to acids. The harder the horse works, the faster this process occurs. Oxygen carried by the blood allows the acids to be converted to harmless carbon dioxide (CO2). When insufficient oxygen is available, lactic acid is formed instead of C02.

What happens to the lactic acid?

The lactic acid leaves the muscle and travels through the blood to other organs-liver, kidney, heart-where it is metabolized-reconverted to glucose or directly used to supply energy. However, this process takes 50 times longer than it takes to convert glucose to lactic acid in muscle.

My horse is already fit and doesn’t need a supplement for muscles. Can the metabolism of lactic acid always keep pace with its production by exercising muscle?

Even though good conditioning of a horse clearly can reduce the rate of lactic acid production, at some point even the highly conditioned horses experience lactic acid accumulation. At high work levels, the metabolism of lactic acid is not able to keep pace with the rate of lactic acid production and secretion into the blood.

What is the “Anaerobic Threshold”?

The Anaerobic Threshold” is the level of exercise intensity at which the production of lactic acid exceeds the ability of the body to remove it from the blood and muscle. If exercise continues, blood lactic acid concentration increases rapidly.

What happens when blood lactic acid concentrations increase?

Blood becomes acidic, inhibiting the secretion of lactic acid from the muscles into the blood. Lactic acid then begins to accumulate in the muscles themselves.

How does blood lactic acid accumulation contribute to fatigue?

The accumulation of lactic acid in muscle causes the muscle to become acidic, interfering with the ability of the muscle to contract.Thus, each contraction-relaxation cycle slows down and a longer time is needed to complete each stride, resulting in fatigue.

How can blood lactic acid concentrations be used to measure equine athletic fitness ability?

Elevated blood lactic acid concentrations indicate a reduced ability to sustain intense activity. Professional trainers have reported that the better performing horses in their barn exhibited the lowest post exercise blood lactic acid concentrations.Because high blood lactic acid concentrations reflect high levels of lactic acid in muscle, which are believed to decrease muscle efficiency, blood lactic acid concentrations are used by trainers to indicate the relative degree of fatigue being exhibited by their horses.

Today’s many horses are highly trained athletes; can their abilities be supported by nutritionally decreasing lactic acid production?

Yes. Conditioned horses are natural athletes that can benefit from the nutrient engineering.

How can nutrient engineering complement training?

Exercise productivity can be supported by oral supplementation of proper ratio balanced branched chain amino acids. Beneficial effects can be indicated by a slower rate of lactic acid accumulation in the blood during exercise and lower heart rates.
