The best source is Organic.

The best hemp juice is organic, field grown, flash frozen and comes from, an Irish based family farm. The juice is carefully
produced and flash frozen to maintain the living enzymes, organics, and nutrition without compromise.

Twin Gear Juicer
Our Twin-gear juice extractor operates at much lower speed than other juicers ensuring that less air gets trapped into the juice, slowing down oxidation of nutrients to a minimum level.
Another important benefit of low RPM is that less heat is generated protecting the nutrients from destruction due to overheating.

Kama Hemp Juice produces superior juices and powders that are exceptionally beneficial for people who are looking for the ultimate healing experience.

It is important to know that some green powders and tablets are dried at temperatures above 400ºC and have only 2% of the bio-activity of the juice.
