My kelp is “Nature’s Way,” and my chlorophyll is GNC brand. (The label says it has alfalfa in it.) A quick search shows that Spring Valley products are sold at other discount retailers such as Walgreens.
I know their Tea Tree Oil has real tea tree in it: can’t mistake the smell or the tingle, and it cures everyone’s funguses.
I use Nature’s Way Kelp as well. The brand seems to be well thought of.
