Which is Better: Vegetarian (HPMC) or Gelatin Capsules?

Part One: Ethics, Sustainability & Functionality

Consumer demand is shifting. You see it every day, especially in the dietary supplement industry. Consumers are asking for more transparency and visibility when it comes to what’s in their medicine cabinet — whether it’s more detailed ingredient lists, clearer sourcing information or more safety assurances from manufacturers. The fact is, consumers are driving the discussion around their health products in terms of sustainability and safety as much as effectiveness. In this evolving landscape, the shift towards plant-based and vegetarian (HPMC) capsules in the industry is more than a trend – it is a necessity.?

Fueling this shift is, in part, the rise of vegan and plant-based diets. Experts report the number of Americans who adhere to a vegan diet increased 600% from 2014 to 2018 for reasons that include animal welfare, environmental impact and media influence.

The movement, however, is driven not only by ethical considerations, but also by science and more practical reasons like safety and product performance. This article will explore the key distinctions between vegetarian capsules and traditional gelatin capsules, and reasons why demand is rapidly shifting towards HPMC.

1. Aversion to Animal Byproducts

Traditional gelatin capsules are derived from animal byproducts, including processed bones, cartilage and skin. While there isn’t direct evidence of transmission from gelatin capsules, there are concerns and perceived risks that come with any animal-based products around the danger of diseases like BSE (mad cow disease). The World Health Organization has raised concerns regarding transmissible spongiform encephalopathies, a category that includes BSE. Vegetarian capsules, on the other hand, avoid this risk entirely, providing a safer alternative.

Additionally, in an increasingly globalized market, complying with diverse dietary restrictions and ethical considerations is crucial. Vegan and vegetarian capsules ensure compliance with Halal and Kosher requirements, enhancing their appeal across various cultural and religious demographics.

2. Ethical & Environmental Considerations

Vegetarian capsules are the clear choice when it comes to sustainability and slowing the effects of climate change. The manufacturing process of HPMC capsules utilizes less energy and water, making it more sustainable and environmentally friendly, according to a report by Capsoleum.

Choosing plant-based and vegetarian capsules is also an ethical decision in terms of animal welfare and animal cruelty. The creation of vegetarian capsules, by definition, means the avoidance of the exploitation and slaughtering of animals associated with gelatin production.

3. Temperature and Humidity Stability

HPMC capsules, thanks to their plant-derived cellulose, are protected by a physically stable polymer that’s resistant to strict heat and humidity conditions. In short, vegetarian capsules handle variations in temperature and humidity better than gelatin capsules. This is important when ensuring product stability and quality for the consumer, as well as protecting the investment of your supply.
