Colostrum’s Peptides Enhance Exercise Results and Make You Smarter

Rebuild sagging muscles, gain lean body weight and defy aging with colostrum, says a new study in the International Journal of Sport Nutrition Exercise and Metabolism. In the eight-week trial on the effect of colostrum supplementation during resistance training in older men and women (average age 59), the participants increased leg press strength and had a greater reduction in bone loss compared to the group taking whey protein. Colostrum peptides “improved upper body strength, muscle thickness, lean tissue mass and cognitive function.”

Growth Factor-I Builds Muscles

In November 2013 in Cellular and Molecular Biology, Dr HJ Korhonen of the University of Tampere, Finland, said these biologically active peptides are “found in abundance in colostrum.” The peptides are delivered through chaperone molecules from the mouth to the gut where they are liberated during digestion, the author said.

One of the peptide-rich proteins that colostrum elevates in the body is insulinlike growth factor-I (IGF-I), which builds muscle. Among high intensity track athletes, colostrum supplementation of eight days led to increases in blood IGF-I levels. The study authors said, “It appears that a bovine colostrum supplement... may increase serum IGF-I concentration in athletes during strength and speed training.”

The Department of Pediatrics, University of Auckland, New Zealand, says bovine colostrum’s chaperone molecules, consisting of fatty acids, inhibit IGF-I degradation in the gut so it is better absorbed.

Lower Serum Creatine Kinase

The peptides in colostrum initiate muscle and tissue repair, aiding recovery for athletes, allowing them to train harder and longer.

At the Center for Research in Education and Sports Science, at the University of South Australia, a doubleblind, placebo-controlled study determined the effect of bovine colostrum on 39 males aged 18-35 who completed an eight-week running program, consuming 60 grams per day of the colostrum or whey protein. By the eighth week the colostrum group ran farther than the placebo group. The athletes receiving colostrum displayed a strong trend to lower serum creatine kinase concentrations while no such finding occurred in the whey group. Creatine kinase is an enzyme that during muscular activity causes the breakdown of phosphocreatine in muscle, which is needed to produce adenosine triphosphate (ATP), the energy molecule manufactured in the cell mitochondria. Without ATP the body lacks energy to repair tissues. Total creatine kinase measurement in serum is a marker for detection and monitoring of skeletal and muscle stress and damage. High levels are undesirable.

Colostum vs Whey Protein

At the University of Delaware’s Sports Science Laboratory investigators determined the effect of colostrum supplementation on body composition and exercise performance in active men and women who either received placebo (whey protein) or colostrum (20 grams per day in powder form). Each person participated in aerobic and heavy-resistance training at least three times per week.

The whey protein group experienced a significant increase in overall body weight (mean increase of 2.11 kilograms [kg]) but not lean body weight. On the other hand, those persons receiving colostrum “experienced a significant increase in bone-free lean body mass (mean increase of 1.49 kg).” Supplementation combination with exercise training for eight weeks “may increase bone-free lean body mass in active men and women,” says the research team.

Increase Traning Capacity

At the School of Human Movement Studies, University of Queensland, St Lucia, Australia, bovine colostrum use produced previously unseen exercise gains. Some 42 cyclists were divided into three groups and required to consume either bovine colostrum or whey protein. One test was to complete a work-based time trial following a two-hour cycle at 65% maximum aerobic capacity. Persons receiving the colostrum “completed the time trial significantly faster…” The researchers conclude that “Oral bovine colostrum supplementation... provided a small but significant improvement in time trial performance in cyclists after a (two-hour) ride at 65% VO2max.”

First-Milk Colostum

Immune-Tree Colostrum produced within the first six hours of birth contains the highest concentration of biologically active proteins, growth factors and peptides.

De-fatted Colostrum Misses Peptides

Immune-Tree utilizes MTVL Laboratories, located in Minnesota, the heart of the dairy country, to test all products for their protein and peptide content. For full peptide effect, the fat content of colostrum makes a difference. Fat acts as a barrier and protects the vital fragile constituents in colostrum when it is spray dried and digested. Without the fat, 35% of IGF-I is lost before digestion and even more once consumed. Unlike Immune-Tree first milking colostrum, some products list zero fat.
