Not only is it safe for older people to take live probiotic cultures, but I would go so far as to say that it is adviseable for them to do so! That is because older people have naturally lower levels of friendly bacteria.

Levels of good bacteria in the large intestine, particularly those from the Bifidobacteria genus, have been found to plummet by as much as 1,000-fold in individuals from 55 to 60 years old onwards1. This imbalance of good and bad bacteria in the gut is thought to significantly contribute to older people's greater sensitivity to infections of the stomach and intestines.
At an older age, we can be more susceptible to health conditions including Inflammatory Bowel Disease (IBD), Irritable Bowel Syndrome (IBS), bloating, diarrhoea and indigestion; all of which originate in the gut. Learn more by reading gut health - all you need to know.
Additionally, the natural deterioration of the immune system due to ageing, can cause negative changes in the gut microbiota of elderly people2.
Supporting the body's balance of good bacteria with a probiotic supplement can help maintain healthy digestion, good immune health, and overall vitality in all age groups - but perhaps especially in the elderly. It is always worth remembering some basic principles when taking probiotics:

Note: Probiotics are not recommended for those with serious medical conditions eg. those who are severely immunosuppressed, have pancreatitis, are in the ICU, have melaena, have a central venous catheter, infants with short bowel syndrome, or to patients with open wounds following major surgery; unless under a doctor's care. Furthermore, pregnant or breastfeeding women should consult their doctor before taking certain probiotic supplements.
