So NOW needs to be dosed a little higher to compare to Fern I guess?This.
Now for a couple unscientific anecdotes:
I tried some Vitamin Shoppe bulk granules and they were lighter in color and did not taste the same. While it could very well have been in my head, I swear I didn't look/feel as full compared to Fearn.
I have since tried NOW's granules which are nearly identical to Fearn in taste/color, although there's a larger ratio of powder-to-intact-granules in the tub, but I've noticed no difference in performance.
