COLOSTRUM
 Colostrum - first mammary secretion that all
mammals provide for their newborns during the first
24-48 hours after parturition.
 It creates the foundation of life-long immunity.
 Colostrum contains various antibodies, and has lower
fat and higher protein content than ordinary milk.
COLOSTRUM
 Colostrum has a nutrient profile and immunological
composition that differs substantially from mature
milk.
 Colostrum contains macro- and micronutrients,
including vitamins and minerals. It contains higher
amounts of oligosaccharides, growth factors,
antimicrobial compounds, and immune regulators.
The nutrients in colostrum
contribute to the maturing
and development of the GI
tract in newborns.
Colostrum starts helping
GI
tract
to
heal
immediately by lowering
pathogens, virus, bacteria,
fungus, yeast, mold etc.) in
the GI tract
 Colostrum has been known for
centuries for its health benefits.

 Humans can rely on bovine
colostrum for their health benefit.
 Another purported use of colostrum
in the early 1950s was for treatment
of rheumatoid arthritis.
Some Physiological Effects of Colostrum
 May increase lean muscle,
 May decrease body fat levels,
 May improve sprint performance,
 May enhance anaerobic performance and buffers lactic
acid build up,
 May improve the recovery between bouts of exercise,
 May enhance endurance performance,
 Can improve immune function,
 Growth factors in colostrum may enhance differentiation
of bone marrow stem cells.
Benefits of Colostrum Supplements
 Because of the rapid gut cell turn over rate (cell replication),
colostrum supplements may help in curing mal-absorption of
nutrients due to GI tract problems such as chronic inflammatory
gut disorder, leaky-gut syndrome.
 Several investigators have reported that the immune and growth
factors present in human and bovine colostrum may not only
benefit the newborn, but may also help the adult humans.
 Since colostrum is a food rather than a drug, its adverse effects
are considered to be minimal, provided the product is obtained
from a reliable source and is prepared using good manufacturing
procedure.

Antimicrobial activity
 Antimicrobial activity of colostrum was tested
using both Gram positive & Gram negative
strains.
 Pour plate method was adopted, according to the
Indian pharmacopoeia 2010.
 MIC of colostrum was calculated by serial dilution
in triplicate and it was found to be around
100µg/ml.
Antimicrobial activity of Colostrum
Minimum inhibitory concentration of colostrum was found to
be 100 µg/ml against:
• E. coli
• S. aureus
• P. vulgaris
• E. aerogenes
• S. typhi
From the result obtained, it can be concluded that
Colostrum is a potent antimicrobial agent.
Anti-inflammatory Actions of Colostrum
• Lactoferrin contained in colostrum has strong antioxidant
characteristics which seem to act by two separate
mechanisms:
(i) binding catalytic iron generated during cell destruction,
(ii) and binding bacterial lipopolysaccharide (LPS) which
causes a decrease in LPS bioactivity, such as increasing
neutrophil O2 production.
•
Colostrum lactoferrin also inhibits the production of
inflammatory cytokines.
• Proline rich peptides (PRP) in colostrum also act as an
oxidative stress inhibitor.
Anti-inflammatory Actions of Colostrum
• Colostrum has anti-inflammatory activity.
• Tumor necrosis factor-α (TNF-α) present in colostrum
bind with the cytokine receptors which control the
inflammatory cytokine cascade, effectively turning off
inflammation at its source.
• Colostrum also contains interleukin-1, the IL-1 receptor
protein, which also acts to inactivate the inflammatory
activity of IL-1.
• Colostrum may be beneficial in chronic inflammatory
diseases, such as various forms of arthritis and Crohn’s
disease, which has been linked to gut inflammation.
Athletic Benefits of Colostrum Supplements
 Research suggests that to enhance supporting
performance, a minimum dose of 20 mg/day is
required, and this may take up to 8-weeks to have a
beneficial effect. It is not clear whether lower doses
(e.g. 10 g/day) would also be effective.
Note: Colostrum appears to be well tolerated. However, some
people may experience gastrointestinal problems such as
flatulence and nausea.

Conclusions
 Colostrum acts as an anti-microbial, anti-oxidant, antiinflammatory and cardio-protective agent.
 Colostrum concentrate was safe in athletes at 20 mg/day
dose.
 Well designed placebo-controlled clinical trials are
required to access the safety and efficacy of colostrum
products.
 Further studies are needed to understand the underlying
mechanisms by which colostrum acts as anti-microbial,
anti-inflammatory and cardio-protective agent.

Biochemical serum estimation of CK-MB and LDH
 The isoproterenol-induced myocardial infarcted control group
had the highest CK-MB and LDH values indicating cardiac
damage.
 Colostrum produced a dose-dependent decrease in the toxicity.
 There was a significant reduction in cardiotoxicity after the
combined administration of 500 mg/kg of colostrum and
0.25mg/kg enalapril on comparison with the isoproterenol
myocardial infarcted group (Group II rats).
 The increase in the CK-MB values and LDH indicate the extent
of isoproterenol-induced cardiotoxicity.

Conclusion
 Colostrum was found to act as an antimicrobial, antioxidant,
anti inflammatory and cardio protective agent.
 Colostrum was safe till a 2g/kg dose.
 Further studies to understand the underlying mechanisms by
which Colostrum acts in inflammation and cardio protection
are required.
Summary and Conclusions
Acute toxicity, antimicrobial, antioxidant, anti
inflammatory and cardio protective effects of Colostrum
were evaluated.
Colostrum was safe upto 2.0 g/kg dose.
MIC of Colostrum was 100 µg/ml.
DPPH free radical scavenging activity assay - 47.07 % at
200µg/ml.
Lipid peroxidation inhibitory assay - IC50 value was
found to be 180 ppm.
Summary and Conclusions
Colostrum alone reduced inflammation (67.94%)
compared to colostrum + diclofenac (59.53%).
Reduction could be due to an antagonistic effect.
Colostrum + enalapril reduced cardiotoxicity more
than colostrum alone.
