Does D-Mannose Block Lectins?
You may be wondering if D-Mannose blocks lectins. We have found a piece of research that shows that d-mannose binds with rice lectins, therefore, it may help to neutralize lectins in rice, even at a small quantity.
Note that I personally found that d-mannose seemed to cause bloating when taken at the typical recommended amount in a supplement – but not when taken in a very small amount.
Typically the amount of d-mannose in a lectin-blocking supplement is very small, so you could try to emulate this if you wanted to get D-Mannose separately and use it individually specifically when eating rice.
D-Mannose may block lectins in other foods as well, we simply have not seen research on it.
