Background and study aims:
Senescence is a normal biological process that is accompanied by a series of deteriorations in physiological function. As we age, our body undergoes several changes, including a gradual decline in immune function, which results in chronic low-grade inflammation. Colostrum milk, also known as "first milk," is a highly nutritious and specialized type of milk produced by mammals during the first few days after giving birth. Colostrum milk is packed with essential nutrients, including proteins, carbohydrates, and vitamins, as well as high levels of antibodies and immune factors. In addition to its immune-boosting properties, colostrum milk has been found to support gut health and improve athletic performance. Hence, this double-blinded randomized controlled trial aims to investigate the effects of bovine colostrum-enriched skim milk on the immune function, antioxidant status, genomic stability and overall health and wellbeing in older adults.

Who can participate?
Older adults aged 50 - 69 years without current or past history of cancer or undergoing chemotherapy, allergies or intolerance to dairy products, chronic kidney diseases or kidney failure, uncontrolled hypertension or diabetes, and heart or cardiovascular disease are eligible to participate in this study.

What does the study involve?
The total duration of this double blinded randomized controlled trial is 12 weeks, and the participants who meet the inclusion and exclusion criteria of the study will be randomized into treatment or placebo group according to gender using computer-generated software (SPSS).

The treatment use for this study is bovine colostrum-enriched skim milk, which contains 150 mg of IgG in each sachet (15 g) in the form of pasteurized milk powder. The treatment product is prepared by blending bovine colostrum powder with instantized skim milk powder. The IgG in the product is derived from the added bovine colostrum powder, with each sachet containing at least 1% IgG, equivalent to approximately 150 mg per sachet. Meanwhile, the placebo for this study is regular bovine skim milk powder, without colostrum enrichment (15 g per sachet). Each participant in the treatment and placebo groups will be instructed to consume the treatment or placebo products, with two sachets to be consumed daily for 12 weeks.

The data will be collected and measured before the intervention (baseline) and after 12 weeks of intervention (post-intervention). The immunomodulatory effects, antioxidant and oxidative stress status and genomic stability enhancement effects will be by using the blood samples collected during baseline and post-intervention. Then, the changes in body mass index, waist and hip circumferences, cognitive function, physical fitness, quality of life, blood pressure and blood clinical profile ( fasting blood glucose, lipid profile, liver function test, renal function test, hematology profile, vitamin D and calcium levels) will be determined by comparing the data during baseline and post-intervention.

What are the possible benefits and risks of participating?
The participants may benefit from consuming colostrum-enriched skim milk or regular milk (placebo). Apart from the potential health benefits derived from bovine colostrum, skim milk is also a rich source of various nutrients, including protein and minerals such as calcium. Additionally, participants will receive free health and clinical laboratory assessments. Since the treatment and placebo used in this study are common dairy products available in the market, the risks for participants are minimal. Furthermore, the study minimizes risk by excluding participants with critical illnesses and uncontrolled chronic diseases, as they may potentially experience complications from consuming the treatment and placebo products.

Scientific titleImmunomodulatory, oxidative damage protection and genomic stability effects of bovine colostrum-enriched skim milk supplementation in older adults subjects: a randomized controlled trial
Study objectivesColostrum-enriched skim milk can improve the immune function, protect against oxidative damage and enhance genomic stability better than the regular skim milk in older adults.

InterventionThe treatment use for this study is bovine colostrum-enriched skim milk, which contains 150 mg of IgG in each sachet (15 g) in the form of pasteurized milk powder. The investigational product is prepared by blending bovine colostrum powder with instantized skim milk powder.
