Double the benefits: It’s Why We Put Vitamin D In Our Signature Probiotic

Vitamin D and probiotics have great synergy.  Both are powerful immune system supporters and in the gut, when taken together, they strengthen each other’s health benefits.   

Kirkman’s Pro-Bio Gold™ with Vitamin D-3, offers our proprietary and most popular probiotic blend (Pro-Bio Gold™) with 1000 IUs of vitamin D-3. 

Studies have shown that the vitamin D pathway is potentially an important modifier of the effects of intestinal flora (probiotics) in the digestive tract.  For example, in one study, mice that lacked vitamin D receptors, which prohibited their ability to absorb vitamin D, showed compromised intestinal health.  Researchers also found a decrease in homing of T-cells to the gut affecting normal, healthy bacterial flora[1].

Conversely, if the gut is compromised by unhealthy bacteria, this can interfere with vitamin D metabolism and absorption[2].

Pro-Bio Gold with Vitamin D-3 offers seven strains of beneficial bacteria for broad spectrum coverage.  These include Lactobacillus rhamnosus, Lactobacillus acidophilus, Bifidobacterium bifidum, Bifidobacterium lactis, Lactobacillus casein, Lactobacillus plantarum and Streptococcus thermophiles.

According to the Environmental Working Group, based on a 2014 analysis of data from the National Health and Nutrition Examination Survey (NHANES), more than half of the general population is vitamin D deficient regardless of age[3]. A serving also offers more than the Institute of Medicine’s recommended daily intake (RDI) of vitamin D-3, which is 400 IUs, but in-line with its cautionary upper intake levels of 1,000 IUs for babies and toddlers and 4000 IUs for anyone 9 years of age or older.
