My guess would be that New York has laws against this type of product or this type of advertising generically, or the penalties or requirements they hold manufacturers to, are too strict for the company to want to deal with.
How much are they charging for all of this. DNA testing is extremely expensive, and I'm not aware of any DNA testing that can determine nutritional needs (not that it might not exist - but I would want proof that the testing can be done, is effective, and is indeed being done). It's more likely that no DNA test is actually done, that all of the individualized reports are not actually individualized at all, and that the supplements are actually identical for everyone, rather than customized. Or that the "genetic test" could just be identifying whether the customer is male or female, and males get one set of supplements, and females get another.
It sounds like a scam to me. It has all of the earmarks. Promises of very "scientific" and customized plans, but little to no proof or evidence to back it up. What they promise sounds an awful lot like a generic daily vitamin.
