From Pond to Pill: Microalgae's Role in Vegan Pharmaceuticals’

Microalgae, photosynthetic microorganisms found in aquatic environments, have gained attention as a potential sustainable source for therapeutic agents. Their diverse biochemical composition and ability to produce bioactive compounds make them particularly appealing for the development of vegan pharmaceuticals. The rise of veganism has created a demand for ethical and sustainable alternatives to traditional therapeutic agents, which often rely on animal-derived ingredients or animal testing. Microalgae have emerged as a fascinating area of research due to their unique biochemical composition and potential health benefits. Microalgae offer a solution by synthesizing a wide range of bioactive molecules, including antioxidants, antimicrobial agents, anticancer compounds, anti-inflammatory substances, and neuroprotective molecules. Bioprospecting microalgae involves screening and isolating these bioactive compounds, tapping into the vast diversity of microalgae species. Moreover, microalgae possess practical advantages, such as rapid growth, high biomass productivity, and the ability to utilize various carbon sources. This chapter explores the potential of microalgae as a sustainable source for vegan therapeutic compounds, discussing species diversity, bioprospecting methodologies, and the challenges and opportunities associated with their development and commercialization. By uncovering the untapped potential of microalgae, we aim to inspire further research and development in the field of vegan pharmaceuticals, aligning scientific progress with ethical and environmental values.
