Acidophilus Nutritional Supplements

Look for strains of Lactobacillus acidophilus listed on the label, an appropriate CFU count for your goal (common ranges from 1 billion to 50+ billion CFUs per serving), and any additional strains or prebiotics if you want broader gut support; also consider enteric coating or delayed-release formulations if survival through stomach acid is a concern

Effective dosages vary by goal, but many adult products range from about 1 billion to 50+ billion CFUs per serving; clinical doses for specific conditions may be higher, so follow product directions or consult a healthcare provider for therapeutic use

Generally safe for healthy adults, but people who are immunocompromised, pregnant, nursing, very young, or with severe health conditions should consult a healthcare professional before starting probiotics

Storage depends on formulation—some require refrigeration to maintain viability while others are shelf-stable; always follow the manufacturer's storage instructions on the label and keep products away from heat, moisture, and direct sunlight

Some people notice changes in a few days, while others may take several weeks; follow dosing instructions—many are taken once daily with or without food—and maintain consistent use for at least 2–4 weeks to assess benefits

Check for expiry or 'best by' date, storage instructions, presence of prebiotics or other strains, allergen information, third‑party testing or certifications, and whether the CFU count is guaranteed through the expiration date

Prices vary by brand, CFU count, number of strains, and formulation; in this category shoppers commonly find budget options under $50 and many mid‑range products around the category average, with higher prices for specialty or clinically dosed formulations
