Are brand name formulas more nutritious than generic brand formulas?

No. They are approved and they should be the same.
No. Nope. The basic nutrient contents are identical. The big differences between brand name and generic formulas are marketing and price tags only.
No. Compare the labels for yourself and you'll see that most generic brand formulas are just as nutritious as their name brand counterparts. Some have slightly different components and it's important to review those with your physician, but for the most part, the nutritional content is very similar.
Yes. Infant formula is much more complete & complex now than ever--spurred by the continuing nutritional research backed by brand name formula companies. So, initially, the brand name formulas benefit from this new information, offering perhaps "better nutrition" than the generic brands--because the generics do not fund such expensive research. Yet, eventually these improvements reach generics also.
Yes. Well.....Yes and no! "brand name" formulas are the most recent. They generally have the most recent changes and additives, often in an attempt to make formula 'more like breast milk'. Generic formulas are often "older versions" of the brand name ones. So, they still meet all of the required nutritional standards and are safe and nutritious. They are usually significantly cheaper.
No. Not much, anyway. One thing that is true about brand name vs. Generic or "store brand" formulas: when a formula manufacturer puts out something new (this happened with adding DHA and ara to formula, and with the evolution of certain carbohydrates) that has come from research (read "expense"), they don't put it in generic or store brand formula. Otherwise, the basic formulation is the same.
No. In general no, they are very similar. In fact, many store brands, such as kirkland's at costco are made by brand name companies.
No. The nutritional value of formulas in america are standardized, so they have similar amounts of calories, protein, carbohydrates, and fat. There are, however, different sources for the ingredients. For example, some formulas use cow milk protein, while others use soy protein. Formulas generally have 20 calories per ounce.
No. Infant formulas in the us are governed by the FDA. All formulas must meet the minimum requirements for nutrition set by the FDA and cannot exceed the maximum amount of nutrients set by the FDA. In general, many of the generic infant formulas are nutritionally comparable to similar brand name formulas.
No. Formulas currently available are all prepared from specific recipes which are different depending upon the formula. They all meet the basic nutritional requirements determined by committees of experts. Although many advertise unique benefits or qualities, none have been proven convincingly superior to any other. Thus for a healthy baby, any formula is fine if tolerated well.
No. All formulas have standardized nutritional value (calories, protein, salt, vitamins), derived from studies of breast milk. The one case I remember of a substandard formula, back in the 1970's, was neo-mull-soy, a brand-name product, and it caused a number of deaths in infants.
No. Generic formulas are completely nutritional for your infant. Some of the generic formulas are actually the name brands in a generic can! . The FDA very closely monitors all infant formula and they all must be nutritionally complete, safe and fortified with very specific items to be sold in the USA. You can also safely switch between different brands, so use coupons and free offers if you get them!
No. For all reputable brands, no. Most "store brands" are really unlabeled enfamil, similac or carnation. The fda highly regulates the ingredients and additives, so there is amazingly small difference. Sure they have small differences and they can tell you theirs is gold and generic is like rat poison, but if you compare notes, generic formula has to meet very strict fda nutritional standards.
