Ray Peat said:Riboflavin can probably be useful when applied topically, but because of its extreme sensitivity to light, it should usually be used only internally, unless the treated skin is covered to prevent exposure to light.
If that is true, I still vote for a version without B2. Because if I use energin on a spot not covered by clothes, the B2 will be destroyed by light. And if I use on a spot covered by light, the B2 makes my clothes dirty. So in both cases, it is better if B2 is removed (for external use).
You could argue that as long as you add vitamin B2 to energin, than energin is not practical for external use. For internal use, it makes sense to add vitamin B2, but in that case it may be an idea to make sure it is in a bottle that blocks light.
Just some ideas, feel free to do whatever you want to do with it :)
Noted, we will change the bottle so that it is not transparent. Thanks for your comments.
