Packaging: I was initially concerned with the bag packaging, but no problem: heavy external paper, interior foil protection, and a strong zip-lock. The spring humidity is now here, and the powder is NOT sticking together at all.
Product: As good as any other Ribose product I've tried elsewhere, and for less cost. No additional ingredients and dissolves easily. What's not to like?
I've been taking D-Ribose for years; although it's my first purchase of Micro Ingredients, I know I'll order again. Three reasons: First, it works, and I know this because of my muscle stamina/energy when doing something like walking up a lot of stairs. Secondly, it's pure: No fillers, additives of any kind. And, finally, I like this better than other products I've tried is because it is so fine a powder, it dissolves IMMEDIATELY in my morning juice...no grittiness in the last swallow. What's not to like!
