Should I take probiotics in capsules, tablets, liquids, gummies or powders?

Probiotic supplements come in numerous different formats, and people are often concerned about which forms of live cultures are best. Should you choose probiotic capsules (also known as probiotic tablets or pills) or probiotic powders? Are gummies effective? Are liquid supplements better than probiotic pills or tablets?

The simple answer is that, if you buy your friendly bacteria supplements from a reputable specialist company, then all formats will be equally as effective. Simple! Therefore, you can just choose the strains and formats which suit you best.
