Why USANA builds these products the way it does — the formulation technology, the in-house manufacturing, the testing, and the published research. The manufacturer's proudest story, told from the source and linked to it.
What InCelligence® technology refers to
USANA's name for the cell-signalling approach behind CellSentials: nutrients chosen, in the company's account, to interact with pathways cells already use rather than simply topping up intake. That is the manufacturer describing its own design — read it in their words below, and watch their video further down.
Why CellSentials comes in two bottles
Core Minerals and Vita Antioxidant are formulated as one system taken together — minerals in one tablet, vitamins and antioxidants in the other. USANA's stated reason is formulation practicality: some combinations are easier to keep stable and dose accurately apart. The label treats the pair as a single serve; so should you.
Where USANA's clinical research lives
USANA runs and funds studies on its own formulations and keeps a public register: what was studied, in whom, and where it was published. We link the register rather than summarise it, so you can read the studies themselves.
How the products are made and tested
USANA manufactures in-house and describes a six-stage path from research to release, with potency testing against what the label declares. Parts of the range carry third-party programs — NSF, ConsumerLab, LGC's Certified for Sport. Which certificate covers which product is on their pages; the sport one matters if you are subject to anti-doping rules.
The manufacturer, in its own words

Before you buy
Use this page to understand how the range is formulated, manufactured and tested. If you take prescription medication, are pregnant, or are buying for a child, have a word with your GP or pharmacist first — they can weigh it against your own circumstances in a way a website cannot.
