IMO, you don't need to purchase food or nutrients labeled "bariatric" just because you had bariatric surgery. READ THE LABEL. That's the important thing. Look at the RDAs and study what they mean at the USDA or FDA websites, or even just by doing a simple Internet search. I'm 16 years out from major RYGB surgery, back in the day when they didn't use laparoscopy or have any specialized product.
Start by learning how many protein grams you need in a day. Then study protein sources--dairy, eggs, meats, fish, beans--and their nutritional content. Once you know how many protein grams are in your desired menu, you can count the calories, get a good match, and figure out your daily and weekly meal plans.
Don't skip oral nutrients like vitamins, minerals & other supplements. My surgeon told me before surgery that I'd have to take two multivitamins every day for the rest of my life. That's pretty serious, especially when you look at the cost. My nutritionist told me to study even more, so I added in things like calcium, iron, glucosamine chondroitin, individual vitamins and minerals like C, D, E, etc. With my prescribed thyroid hormone and cholesterol meds, I was taking 22 pills a day in four doses. You can't take two minerals in the same 2-hour period. They cancel each other out. So you don't take iron with calcium, etc.
Anyway, when you're looking at support groups and "nutrition" sites, keep in mind that these (including this one) are provided as a service to you so the corporations that pay for their existence have a captive audience to pitch their supplies to. Your best bet is to study actual scientific sites supported by government entities. They have no vested interest in your recovery or how you get there.
Here's a good place to start:

And as I said, I had my surgery a long time ago, and before surgery I NEVER had outstanding results in complete blood counts. Since surgery, I'm a superstar in the doctor's office.
Forget products that target you. Learn the truth about what you're putting in your body. Shakes and powders and other additives tell you a pretty story, but labels never lie. A little knowledge is a dangerous thing--to hucksters and frauds.
