One of the most important elements in your regular diet is protein.  Proteins are made up of chemical “building blocks” known as amino acids. Amino acids are used by your body to build and repair muscles and bones and also to make hormones and enzymes. In addition to this, they can be used as an energy source. Protein bars can be a good way to add minerals, protein, carbs and vitamins into your diet. As well as this they can also reduce your appetite, power a workout, and assist muscle repair after exercise. Having said that, they won’t replace the quality and nutrient composition of whole foods.

About The Manufacturer

Costco is an American multinational company and retailer, known for its chain of membership in big-box retail shops. Costco has manufacturing and distribution rights to the Kirkland Protein Bars. As of 2022 Costco was the fifth largest retailer in the world according to wikipedia.

Costco is known as Costco wholesale corporation and it has its headquarters in Issaquah, Washington. On the other hand, the Kirkland Signature brand started its journey in Kirkland, Washington. Thus the big brand name. Eventually, the Kirkland Signature Brand moved to Issaquah as well.

The Costco wholesale corporation is a huge business. Costco has about 804 warehouses all around the world and turns over in excess of $120 billion per year.

Costco was selling other companies’ products for a while but then decided to start manufacturing products of its own. This is where the Costco Wholesale Corporation started the journey of the Kirkland Signature brand. It is the private label of Costco.

Costco introduced the Kirkland Signature Brand in 1995. Since then the Kirkland Signature Brand has been a game-changer for the Costco Wholesale retailer and it is challenging big brand manufacturers hoping to earn or retain their precious spot at the warehouse retailer. Costco has used its Kirkland product ranges to bring in shoppers en masse, all the while building a reputation for quality and low prices on kitchen towels, toilet paper, t-shirts, butter and even golf clubs bearing the subtle red logo.

Kirkland Signature brand is also responsible for one-third of the profit margin for Costco.

Our research team compared the two bars and here is the verdict,
Kirkland Protein Bars- Price $1 per bar (only available in large boxes), Taste – Superb, especially Cookie Dough (my favorite!), Texture-A little chewy, but not hard, Flavour Options- Only 4 flavors are available.

Quest Protein Bars-Price $2.30 av retail price, can buy single bars, Taste – Pleasant with that distinctive “Quest” flavor, TExture – Slightly chewy, but softer than Kirkland Protein Bars, Flavour Options – Over 20 Flavours available.
