Body weight and temperature, SPO
2 and pulse rate, oocyte quality and reproductive performance and blood and plasma biochemistry profiles of multi-ingredient supplement and control groups are presented in Table (1-4).
Body weight, rectal temperature, SPO2 and pulse rate
Changes of body weight, rectal temperature, SPO
2 and pulse rate are presented in Table (1). Value of final body weight (g) was significantly decreased in multi-ingredient supplement group compared to that of control group. On the other hand, hyperthermia of rectal temperature (°C) was recorded in multi-ingredient supplement group. Additionally, pulse rate and SPO
2 were not differed between both groups.
Monitoring oocyte quality and reproductive performance
Values of oocyte quality and reproductive performance are presented in Table (2). Percentages of GV oocytes with diameter 70.0 and 80.0 µm were lower in multi-ingredient supplement group compared to those of control group versus the percentage of GV oocytes with diameter 60.0 µm if compared to control group. Simultaneously, pregnancy rate and number of pups per female were decreased (P<0.001) in multi-ingredient supplement group compared to control one.
Blood and plasma profiles
Values and blood and plasma profiles are presented in Table (3-4). Values of blood parameters were significantly improved in control group compared to multi-ingredient supplement group (Table 3). Regarding to plasma profiles, total protein values were increased whereas urea, creatinine, glucose, aspartate aminotransferase, alanine aminotransferase and lactate dehydrogenasevalues were significantly decreased in multi-ingredient supplement group versus control group.
Results of the current study are presented in Table (1-4) indicating the effects of dietary (1.5%)
C.
forskohlii, green coffee bean and green tea for each supplement on body weight, reproductive performance, hematological profiles in mice. Generally, the obtained results indicated significant decrease of body weight gain, blood and plasma profiles in addition to increase of rectal temperature and plasma total protein in the multi-ingredient supplement group compared to control group. Furthermore, the reproductive performances represented by oocyte quality and pregnancy rate and delivered pups were significantly decreased in the multi-ingredient supplement group compared to control group. These effects could be owing to the common ingredients in
C.
forskohlii, green coffee bean and green tea including botanicals (herbs and other plant components), caffeine, dietary fibers and minerals. Both
C.
forskohlii, green coffee bean and green tea contain various compounds, some of which can be potentially harmful if consumed in excess amount.
Dietary
C.
forskohlii and its extracted compound, forskolin, have been explored for a variety of potential health benefits
(Amezcua et al., 2022; Roshni and Rekha 2024). These benefits may include body weight loss, improved diabetes and cardiovascular health, increased muscle mass and enhanced blood flow to the brain
(Abbasi et al., 2023; Mohammed et al., 2024d,e). The primary active ingredient in green coffee is chlorogenic acid. This compound is believed to be responsible for many of the potential health benefits as anti-obesity, regulating glucose and lipid metabolism, antioxidant and anti-inflammatory impacts
(Tajik et al., 2017; Yu et al., 2022; Nguyen et al., 2024). The primary active ingredient in green tea is a group of compounds called polyphenols, specifically catechins
(Farhan, 2022). Among these catechins, epigallocatechin gallate is considered the most potent and abundant compound. These compounds are responsible for many of the health benefits attributed to green tea as antioxidant, weight management, improved diabetes and heart health properties
(Du et al., 2012; Legeay et al., 2015;
Mohammed and Al-Hozab, 2019).
Collectively, the percentage 1.5% of each supplement resulted in lower body weight gain, hyperthermia and hypoglycemia if compared to basal control diet. Furthermore, values of blood cells and plasma profiles (urea, creatinine, glucose, aspartate aminotransferase, alanine aminotransferase and lactate dehydrogenase) were decreased in multi-ingredient supplement groups except total protein if compared to control group. It seems that such supplements gave adverse effects in some parameters due to excess supplemented amount or harmful ingredients as caffeine, tannins and oxalates
(Noonan and Savage 1999;
Duda-Chodak and Tarko 2023).Tannins are polyphenols found in both green tea and green coffee offer some health benefits, while excessive tannin intake can interfere with iron absorption and may worsen digestive issues
(Delimont et al., 2017; Duda-Chodak and Tarko, 2023). Excess caffeine can affect various aspects of female reproductive performances including slight decrease estrogen levels, possible delay in conception, increased risk of miscarriage, stillbirth and lower birth weight
(Wen et al., 2001;
Karypidis et al., 2006; Weng et al., 2008; Greenwood et al., 2010;
Wikoff et al., 2017; Bu et al., 2020), where we found lower quality of GV oocytes and pregnancy rate in this study. In addition, the lower reproductive performance in supplement group could be also attributed to decrease of steroid hormone values due to the changes in lipid metabolism, low glucose level and body weight gain
(Senosy et al., 2018; Mohammed et al., 2022).
