'For daily immunity' is an expert combination of live cultures and natural plant extracts, including green tea, grape seed, pine bark, as well as Vitamin C. Vitamin C has been shown to help support a healthy immune system. 'For daily immunity' contains well known live cultures such as Lactobacillus acidophilus, Bifidobacterium longum, Bifidobacterium breve, and Bifidobacterium infantis - all tested and proven to survive stomach acidity to reach the intestinal tract alive.

Recent research on probiotics and immunity

Below are clinical trials looking generally at probiotics and immunity.

Combination of Probiotics & prebiotics improve anti-oxidative activity - January 2008 - A blend of Lactobacillus and Bifidobacterium probiotics with the prebiotic oligofructose was linked to a reduction in the oxidation of LDL, associated with hardening of the arteries. This EU and MicroFunction Project concluded that the overall antioxidant activity of the participants taking synbiotic supplements was higher than the antioxidant activity of placebo subjects.

Probiotics support athletes with infections and colds- July 2014 - The latest research published in the Journal of Science and Medicine in Sport in July 2014, performed a randomized controlled trial on thirty elite rugby players in New Zealand. The players were allocated in random order to either receive probiotics or a placebo for four weeks each. It was found that the athletes had about 40% fewer colds and gastrointestinal infections when they took a probiotic compared to when they took a placebo.

Probiotics reduce duration of respiratory illness and days off sick - July 2014 - In a Meta-analysis published in the British Journal of Nutrition in July 2014 twenty randomised control trials looking at the effect of probiotics and immunity were considered. It was concluded that ‘the average duration of respiratory illness episodes, the number of days of illness per person and the number of days absent from day care/work/school are significantly reduced with probiotic treatment compared with placebo’.

Antioxidants & Natural Plant Extracts for Immunity

Below is a small selection of the research on the natural plant extracts (antioxidants) found in OptiBac Probiotics 'For daily immunity'.

Grape Seed Extract can destroy leukaemia cells - January 2009 - Scientists at the University of Kentucky found that within 24 hours of exposure to Grape Seed Extract, 76% of leukaemia cells died through apoptosis, a natural process of self-destruction. This research could potentially provide new areas of treatment for leukaemia, a disease that affects over 24,000 people each year. Grape Seed Extract, previously shown to reduce the size of breast tumours in rats and skin tumours in mice, contains numerous antioxidants including resveratrol – a component known for its anti-cancerous properties. Head researcher, Professor Xianglin Shi added, “What everyone seeks is an agent that has an effect on cancer cells but leaves normal cells alone, and this shows that grapeseed extract fits into this category.”

Green Tea good for the heart – July 2008 - A small Greek study found that habitual consumption of green tea could ameliorate the function of the endothelial cells (the cells lining the walls of blood vessels), therefore boosting cardiovascular health. The study indicated the possible role of green tea polyphenols, which have previously been linked to protection against some cancers and Alzheimer’s disease.

Pine bark has anti-inflammatory and analgesic activities - 2012. A study published in the Advances in Pharmacologcial Sciences (2012), tested a pine native to the Himalaya. Pinus roxburghii Sarg. (Pinaceae) where it is traditionally and extensively used in number of herbal preparation for curing inflammatory disorders, this study was undertaken to assess analgesic and anti-inflammatory activities of its bark extract. Dried and crushed leaves of this pine were defatted with petroleum ether and then extracted with alcohol. This was then subjected to evaluation of analgesic and anti-inflammatory activities in experimental animal models. It was found that the alcoholic bark extract of demonstrated significant analgesic and anti-inflammatory activities in the tested models.

Vitamin C reduces the frequency of the common cold - 2006. A study published in the European Journal of Clinical Nutrition (2006) conducted a double blind 5 year randomized controlled trial. Daily supplementation of vitamin C was given to participants. It was found that this significantly reduces the frequency of catching a cold.
