Frequently Asked Questions
Do I need to refrigerate probiotics?
Not always. Some formulas require refrigeration for best stability, while many modern products are shelf‑stable and formulated to remain viable without refrigeration. Follow the manufacturer's storage instructions and keep products in a cool, dry place when possible.
How many CFUs do I need for immune support?
There’s no single CFU number that fits everyone. Effective products range from low billions for children to tens or hundreds of billions for adults seeking broad coverage. Choose a product with clinically studied strains and start with the recommended dose; consult a healthcare provider for personalized advice.
Can children take adult probiotic capsules?
Children can sometimes take adult formulas, but age recommendations and taste/format matter. Kid‑specific packets or chewables are designed for dosing and palatability; always check the label for age limits and consult a pediatrician before giving adult products to young children.
