Probiotics are live microorganisms that provide health benefits when consumed in adequate amounts. They are commonly found in fermented foods such as yogurt, kefir, sauerkraut, and kimchi. Additionally, probiotic supplements are also available in various forms, such as capsules, tablets, and powders.

The timing of when to take a probiotic largely depends on the reason for taking it. For example, if you are taking a probiotic to support digestive health, it may be beneficial to take it with or just before a meal. This can help ensure that the probiotic reaches the intestines, where it can have the most impact.

However, if you are taking a probiotic to support immune function, it may be more beneficial to take it on an empty stomach. This is because stomach acid can destroy some probiotic strains, and taking it on an empty stomach can help ensure that the probiotic reaches the intestines intact.

It's also important to note that the specific strains and dosage of probiotics can vary depending on the individual's health goals and needs. Therefore, it's always best to consult with a healthcare provider before starting any new supplement regimen, including probiotics.
