To answer this, we ran a blinded home-use study in July 2025 (n=128, U.S.), comparing collagen in liquid, powder, capsule, and gummy form. Participants evaluated taste, convenience, and likelihood of continued use.
Key Findings
1. Routine drives adherence Formats that fit seamlessly into daily life encourage consistent use. Capsules and gummies scored high on convenience, while powders and liquids offered dosing flexibility aligned with clinical recommendations.
2. Perception vs. dose Participants rated products with collagen doses ranging from 0.1 g to 20 g similarly after a short trial. This gap between perceived and actual efficacy highlights the need for clearer communication around dosage.
3. Liquids stand out Liquid collagen combined high-dose capability with ease of use and positive taste feedback. One sachet tested delivered 11 g of collagen, the equivalent of 18 capsules or over 100 gummies, yet was rated enjoyable and convenient.
Why Liquids Matter
Clinical research suggests daily intakes of 5 g+ are needed for visible skin benefits over 12+ weeks. Liquids make this dose achievable in a single serving, supporting both adherence and results. Their adaptability, ready-to-drink, mixable, or combined with other actives, positions them as the most versatile format for future innovation.
Takeaway: Consumers want supplements that are enjoyable, easy to integrate, and clinically effective. Liquids bridge these needs better than any other format, making them a leading choice for next-generation collagen products.
