Tag: Adjusting to probiotics

While probiotics are considered safe for most healthy individuals, a small percentage may experience mild side effects, such as nausea or digestive upset, during the initial adjustment phase. The question, "Can probiotics cause nausea and vomiting?" is common, but it's important to understand the underlying reasons for this reaction and how to manage it.

According to a 2025 article, most people can expect their bodies to adjust to a new probiotic regimen within 2 to 4 weeks, with noticeable digestive changes occurring sooner. This adjustment period can vary based on individual factors like current gut health, probiotic strain, and dosage.
