Meanwhile, consumers seem to be interested not only in exercise and diet control but also in which ingredients are effective for weight management and the mechanisms of each ingredient. A significant 25% proportion of the weight loss supplement segment in the weight management and well-being market supports this. Moreover, the CAGR of weight loss supplements is relatively high at 3.1%4), which has led to overall growth in the weight management and well-being market. Given the importance of ingredient selection and development in this market, the market responds to the needs of increasingly segmented consumers with both classically known ingredients and newly discovered ingredients — from vitamins and amino acids to botanicals and probiotics5). As consumers look for products that are optimized for them, the weight loss supplement market has been growing with the growing interest of consumers in health.
Discovering consumer needs in the weight loss category
- Factors that Influence Consumers When Choosing Wellness Products
What are the characteristics of wellness-related products that consumers commonly prefer? A research institute proved that consumers prefer products tailored to individuals, with many respondents selecting “Effective/works for me” and “Addresses my specific needs.”6) This preference shows that individual needs have diversified according to specific health areas and that “there’s no magic pill for everyone” (Figure 3). Moreover, consumers in the United States generally expect high-quality products, as evidenced by the “High quality” item. While various factors can affect product quality, “sciencebacked” and “clean/all-natural ingredients” are two key indicators that consumers consider significant.6) This indicates that consumers place a high value on the scientific validation of ingredients and products (Figure 3).
So what criteria do consumers use to compare various products and select the product that best suit their needs? According to the aforementioned institute, consumers prefer clinically proven ingredients over those that are simply organic or natural in all product types, and in particular, the preference for clinically proven ingredients is three times higher for the supplements category7). In other words, clinically proven efficacy is the most important criterion for consumers when choosing a product. Product development capabilities based on the clinical verification of efficacy have become increasingly important in the current industry, reflecting common consumer needs across all health categories.
- Consumer Pain Points for Weight Loss Products : Possibility of Continuous Intake
In conclusion, it was confirmed that consumer needs for “clean/all-natural ingredients,” “science-backed,” and “clinically proven” products must fundamentally be met.
Product development is ongoing in the weight loss supplement market based on ingredients known to help with weight loss, such as amino acids, vitamins, botanicals, herbs, and pre/ probiotics.5) The problems are that not all ingredients have fully proven functionalities and some may have adverse health effects when taken continuously8) (Figure 4). Based on consumer trends according to a qualitative review of ingredients and the aforementioned clinical verification, these two problems are the factors that cause consumers to give up their choices. When all of this is considered, consumer needs for current weight loss products emphasize “safety and sustainability when taking them.” Therefore, it is generally necessary to use ingredients that are perceived by consumers as safe and effective. One thing to note is that compared to other ingredients that lack sufficient trial data to prove functionality or for which there are concerns about adverse health effects, probiotics have been proven effective and considered generally safe (Figure 4). Probiotics have expanded beyond gut health to the weight loss category to meet diverse consumer needs. In other words, probiotics can be used as a safe and effective solution to support a gradual and sustainable diet as an ingredient free from the issues related to continuous intake.
