Deal updates for Dr. Formulated Probiotics Once Daily Women's 50 Billion
Garden of Life's Once Daily Women's is one of the best-selling probiotics in the US: 50 billion CFU from 16 strains, including Lactobacillus strains chosen for women's digestive and vaginal flora, in a single shelf-stable vegetarian capsule. The women's companion to the Dr. Formulated probiotic already on the site.
There's no single right number; products range from 1 to 100+ billion CFU per serving and strains matter as much as counts. The label lists CFU and the named strains — compare those, and check whether the count is guaranteed 'through best-by' or only 'at time of manufacture'.
Check the label: some probiotics are shelf-stable, others say 'keep refrigerated'. Shelf-stable products are easier to travel with; refrigerated ones should stay cold from the store to your fridge.
Follow the label. Many probiotics suggest taking them with a meal; fiber supplements are taken with a full glass of water and spaced away from medicines. Consistency matters more than the hour.
Probiotics are live bacteria; prebiotics are fibers that feed the bacteria you already have. Some products combine both ('synbiotic') — the label will say so.
