What CUSTOM PROBIOTICS Inc. does

Custom Probiotics Inc. is a privately held, founder-operated dietary supplement company founded in 1998 and headquartered in Glendale, California. The company formulates and sells high-potency, professional-grade probiotic supplements for children and adults, with product potencies ranging from 50 billion to over 400 billion CFUs per serving. The portfolio comprises multi-strain formulations (Adult Formula CP-1 capsules, 11 Strain, Six Strain, D-Lactate Free, Infant Formula, Five Strain Bifidobacteria, Four Strain Lactobacilli), 19 distinct single-strain powders covering Lactobacillus, Bifidobacterium, and Streptococcus Thermophilus species with specific strain designations, two yogurt starter cultures, and a custom blend service allowing customers to combine any single strains. Underlying product technology relies on freeze-dried probiotic formulations with no fillers or allergens; potency is verified by an independent laboratory testing program that has been continuous for over 14 years and is publicly disclosed.

The business operates exclusively as a direct-to-consumer e-commerce retailer through customprobiotics.com (and customprobiotics.ca for Canadian customers), with no third-party retail, marketplace, or wholesale distribution. Products are sold on a one-time purchase basis at unit prices ranging from $60 to $155, with a six-bottle bulk discount on the flagship CP-1 capsules. Customers are primarily health-conscious individuals, parents purchasing for infants and children, and a secondary segment of healthcare professionals (naturopaths, nutritionists, functional medicine practitioners) who recommend the products to patients.

Revenue mechanics are entirely DTC transactional, with free domestic shipping and orders processed Monday through Thursday. The company is bootstrapped with no external funding, employs 1-10 people, and is owned and operated by founder Harry Bronozian, MS. Marketing relies on organic SEO, an educational blog, customer testimonials, and an email newsletter via Constant Contact, with no evidence of paid acquisition at scale. The company is not listed on any stock exchange, has no subsidiaries, partnerships, or M&A activity in its history.
