One of the most important things to consider when buying a probiotic is the manufacturing process. Because probiotics contain live cultures, it is essential that companies package them properly and in the right conditions.
iHerb, the company that manufactures California Gold Nutrition LactoBif Probiotics, states that it uses climate-controlled, GMP-certified warehouses. This means there is a reduced risk that the probiotics will be less effective due to exposure to cold or heat.
The company uses a third-party lab to test each batch. The third-party lab ensures that the CFU count is accurate, that the strains have not been contaminated with pathogens such as salmonella or E. coli, and that they undergo heavy metal analysis.
Additionally, iHerb provides CFU analysis for each batch of probiotics. The company states that its LactoBif blends contain at least double the number of CFU when compared to the label on each product.

Medical Perspective“Probiotics can be taken safely by most people, but they can be inappropriate for individuals who live with weakened immune systems or serious illnesses and for those with central lines (central venous catheter) where there could be some risk of infection. Probiotic use can sometimes cause symptoms like bloating or gas, and it’s important to note that people with conditions like Small Intestinal Bacterial Overgrowth or severe pancreatitis may need to avoid probiotics, or carefully select their products under direct medical guidance.”
