A couple of weaknesses include the potential need to consume multiple capsules to meet your daily fiber intake, which might be cumbersome for some individuals. Additionally, while it helps support healthy blood sugar levels and heart health, these benefits may vary from person to person and should be considered as part of a healthy lifestyle.
