Add 1 cup of juice, spirulina, wheatgrass, & chlorella to a bowl and stir in 6 T of beef gelatin until fully incorporated.
Set this bowl aside.
In a small saucepan, add the other 1 cup of juice.
Heat this juice until it is steaming, but not boiling.
Once heated, dump the juice into the gelatin mixture.
Stir until the gelatin is completely melted and incorporated.
Next, use a dropper to add the gelatin mixture to silicone gummy bear trays (or whatever shape you want).
Once the mold is full, place the mold into the refrigerator for 10 minutes.
Once the gummies have set, take them out of the molds and store in an airtight container in the refrigerator.
