Restraint/Challenge

Regulatory Compliance and Consumer Skepticism

• Variability in consumer responses to dietary supplements and program adherence may limit perceived effectiveness, affecting long-term retention and satisfaction
• Limited awareness or mistrust of AI-powered health solutions among older adults or less tech-savvy populations can slow market penetration despite growing digital adoption trends
