I certainly can appreciate the difficulty when dealing with something that costs $70 a bottle. With the two of us supposed adults here at our place, we stretch our bottle of the adult version by alternating every second or third day with a superfoods powder mix (it's a custom blend modeled after a Schulze formula with added acerola cherry) and sometimes either some juiced veggies or some sea veggies capsules and perhaps a B12 supplement on the off days.
