Monde Selection was founded in the heart of Europe in Brussels, Belgium, with the aim of providing the most impartial and independent evaluations. Since 1961, this international quality research institution has acquired unique expertise in assessing the quality of food and health products worldwide. Each year, Monde Selection invites over 80 internationally renowned experts from various fields for a five-month evaluation process. Products from over a hundred countries compete, totaling more than 3,500 items, and each product is judged based on up to 25 parameters to determine the final evaluation outcome. Currently, the evaluation categories of Monde Selection include food, alcoholic beverages, drinking water and soft drinks, spirits, nutritional and health products, cosmetics, nutritional labels, and international wine competitions.

In the evaluation of nutritional and health products, Monde Selection's panel of judges carefully examines the detailed ingredients of each product, relevant information, statements related to nutritional health, and key characteristics of the product's active ingredients. Laboratory analysis is also employed to complete the product evaluation.

The mission of the judging panel is to verify the claims made by products and their health purposes based on the latest scientific research and data, as well as evaluating the intrinsic quality of the products in terms of nutrition, biochemistry, and more.

Monde Selection has become a widely recognized and prestigious certification organization. The evaluation results include four major categories of awards:
  - Grand Gold Quality Award (representing final evaluation results ranging from 90% to 100%)
  - Gold Quality Award (representing final evaluation results ranging from 80% to 89%)
  - Silver Quality Award (representing final evaluation results ranging from 70% to 79%)
  - Bronze Quality Award (representing final evaluation results ranging from 60% to 69%)

Additionally, each year, five products are nominated as nominees for the Jury of the Year from among the 3,500 products evaluated. This is one of the top honors in the world of certifications, and products receiving this nomination are recognized by the judging panel as having exceptional formulas and quality.

  - Products that receive the Gold Award or Grand Gold Award for three consecutive years are further awarded the International High-Quality Trophy.
  - Companies that receive awards continuously for ten years are presented with the Crystal Honorary Trophy.
  - For those that achieve a continuous streak of 25 years, the 25th Anniversary Trophy is awarded.
  - For those with a continuous streak of 40 years, the Emerald Prestigious Trophy is presented.

The Vegetarian Society in the United Kingdom was founded in 1847 and is a third-party charitable organization with a history of over 175 years. Its primary mission is to promote vegetarianism and high-quality food. Shortly after its establishment, the Vegetarian Society gained recognition from numerous brands and businesses. By 1853, it had 889 corporate members, and by 1897, the number of certified brand members had exceeded 5,000.

Entering the 20th century, the focus of the Vegetarian Society's work primarily shifted towards public education. To fulfill this mission, the Vegetarian Society in the United Kingdom collaborated with other community groups to educate the public about the benefits of a healthy diet. The society also engaged in political activities as an advocacy group with the aim of influencing food producers to remove non-vegetarian ingredients such as gelatin or cheese made using animal rennet from their products. They hoped that manufacturers could obtain certification and label their food products with the society's trademark symbol. This certification included criteria such as the use of free-range eggs, with different V-shaped symbols representing different meanings and certifications. The Vegetarian Society also took a leading role in the movement against labeling products containing fish as vegetarian. As part of this movement, in 1995, the society produced the documentary "Devour the Earth," which was written by Tony Wardle and narrated by Paul McCartney. The documentary aimed to raise awareness about the environmental impact of meat consumption. In 2017, the society further expanded its efforts by introducing a Vegan certification. This certification aimed to highlight the category of vegetarian ingredients affected by different processes and components. It received an immediate positive response from numerous businesses. In 2022, McDonald's launched the McPlant burger, which was certified by the Vegetarian Society, demonstrating the organization's ongoing impact and influence in promoting vegetarian and vegan options in the food industry.

The American Vegetarian Association (AVA) is a third-party impartial organization founded by Len Torine in 1999. It was established because of the lack of clear regulations from the U.S. FDA regarding vegan, vegetarian, or plant-based labels. Over the past 20 years, the AVA has certified products of various categories, including food, beauty products, dietary supplements, and household items, ranging from startups to Fortune 500 companies. The AVA has collaborated with companies such as Taco Bell, Nordic Naturals, Nuun, Smartypants, Starbucks, Clorox, and Danone. The primary goal of AVA is to provide a widely recognized certification program to enable individuals with vegetarian preferences to make accurate dietary choices.

Today, the American Vegetarian Association offers certification for different categories, including vegan (completely free of animal products), vegetarian (free of meat but may include animal products like dairy and eggs), plant-based ingredient products (containing plant-based ingredients), and products with no animal ingredients (completely devoid of any animal-derived components). This effort aims to provide consumers with precise information so they can make choices that align with their dietary preferences.
