Vitamin B-complex alone is not a weight loss solution, but it can play a supportive role in maintaining overall health and metabolism, which may indirectly aid in weight management. B vitamins, particularly B1, B2, B3, B5, B6, and B7, are involved in energy production, carbohydrate metabolism, and fat utilization. However, simply taking vitamin B-complex supplements without making lifestyle changes, such as adopting a balanced diet and engaging in regular physical activity, is unlikely to result in significant weight loss. For effective and sustainable weight management, it's important to focus on a comprehensive approach that includes a healthy diet, exercise, and overall lifestyle improvements. Consulting a healthcare professional or registered dietitian can provide personalized guidance.
