BulkSupplements.com Naringin Extract Powder (500 Grams - 1.1 lbs)

Is the Naringin powder considered food grade? I need it to prep as reference samples for training a sensory panel who will taste and evaluate it.

Each time i order this, i receive the wrong item, like vitamin c powder or stevia extract. why is that?

What’s with all the complaints of a mislabled product?

Does any of the material or processing of this product come from China?
