Hello again everyone!:)

Okay,

I have taken the two ingredient lists from greatgoldens.com for the diamond and costco lamb and rice formulas. Every single ingredient in the costco/kirkland formula is in the diamond formula except the following. The ingedients that are not found in the costco formula are brewers rice, iron proteinate, zinc proteinate, copper proteinate, manganese proteinate.

As well as these ingredients the greatgoldens.com website states that the diamond formula contains chelated minerals and the costco formula does not.

Can someone please advise me about what these "proteinate" ingredients are that are not located in costcos formula. I would assume that the chelated minerals that are in diamond but not costco are directly related to these proteinate ingredients. are these important to have in my Jackson's food. The reason I ask is that in my area Kirkland Lamb and Rice is about 23.00 canadian and the Diamond Lamb and Rice is 50.00 canadian. Are these ingredients worth paying 27.00 extra per bag for. If they are I don't mind paying for them but don't want to pay for nothing.

So, my two questions are this.
What are the Proteinate ingredients that are missing in the costco formula?
What are chelated minerals?

Any replies are greatly appreciated and thanks for taking the time to help me out.

I'm going to move this to the Diet/Nutrition area ... it might get more attention there. :) Sorry, I'm absolutely clueless about answering your question, though.

From my quick research, I think the word Proteinate at the end of the minerals is what is considered the Chelated Minerals.

Per a site I found on vitamins: Chelated Minerals are the dosage form most-often recommended to assure proper daily intake. Chelation is the pharmaceutical process of bonding each mineral to an amino acid. This bonding makes it easier to digest and assimilate each nutritive mineral for proper utilization in the body.

For example another site (for Wellness food) listed the proteinate minerals with a note (a chelated source of.....).

Whether this is something you really need to look for in a dog food, I don't know. I personally am only buying the Kirkland L&R...for the good ingredients and for the cost. I wouldn't spend the extra for the chelated minerals.
