A typical 1 oz serving of lotus seeds contains 4.3 grams of protein (15.4 g per 100 g), which makes it a moderate source of protein. That covers roughly 9% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Around 19% of the calories in lotus seeds come from protein, so it is more of an energy food than a protein food. It contributes to a day's protein total, but the bulk of what it delivers is energy rather than amino acids - treat it as a contributor alongside a denser source, not as the protein in a meal.
Among the 27 seeds in the database, lotus seeds ranks 23rd by protein per serving, and 523rd out of all 796 foods on the site. Set against flaxseed, another seed entry in the database, a serving carries about 0.5 g more protein (flaxseed has 3.8 g per 2 tbsp).
It is an incomplete protein on its own; pairing it with other plant foods across the day covers the full range of essential amino acids. The serving above is measured by weight at 28 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
