### ⭐⭐⭐⭐⭐ Very good high quality product but too costly.
*by S***R on 1 February 2017*

I love lots of products from Throne. they always produce the best direct form of vitamins. same to this. its vitamin b2 but in Active, direct form of R5P. and i believe the quality is excellent too. i don't know why but it's difficult to find the active form of this b2 in the UK easily. and only downside is the price. too expensive. there are many normal b2 (not in active form) out there in 1/3 price of this. and you only receive 60 caps per bottle so have to say, this is one expensive product but i have to continually buy it because of my daughter needs this every day for her condition..
