Another thing worth looking into is whether you are deficient in one or more nutrients. Even though Huel contains the standard recommended amounts for all nutrients, these amounts are calculated to prevent the average person from getting ill. People are individuals, and some people need more of some nutrients.
The symptom for deficiency of some nutrients includes constipation. These include Vitamin B1, Vitamin B12, and Magnesium. The owner of a health shop once told me that many people struggle to absorb B12 properly in the digestive system, so taking sublingual B12 can be helpful for some people.
Another recommendation: eat a few Huel bars. They definitely make me go. I think it’s the polydextrose.
If all else fails, get some Mag07 pills. It’s a special form of magnesium that increases the water content of your stools. Take 5 of those each day and you almost certainly won’t have any problem going.
