Constipation can be related to many factors, you may want to check into those factors. The following supplements will help you address the symptoms like modern medicine does, it addresses the symptoms not the cause and create more problems eventually. A more homeopathic approach would be to look deeper of what maybe the cause of your constipation. Check at other possible chronic illnesses that could cause constipation such as adrenal fatigue, candida, SIBO, or high stress. If you are taking proton pump inhibitors you may want to discontinue them and they significantly slow down digestion.

Bulletproof InnerFuel Prebiotic - Plant-Based Dietary Fiber for Super
This is a combination of many different fibers, some of the other mentioned in this stack. All the fibers in this supplement are well-studied, however it's very expensive for what it contains. You can give it a try to get some boost in your recovery and then go back to the other cheaper fibers. Unfortunately I havent found another supplement similar to this one yet.
