The 5 Questions Customers Ask Before Buying a Functional Beverage (And What the Answers Tell You)
What is a functional beverage, and does Sweet Mango Splash qualify?
A functional beverage is a drink built around an active whole-food or botanical ingredient — not just flavor and sugar. Sweet Mango Splash is a non-alcoholic functional beverage made from mango juice, organic broccoli, organic spirulina, and mushrooms — with no added sugar and a 2-year shelf-stable format. We call it functional because it's built around a real whole-food ingredient, broccoli, rather than flavoring and sweetener.
Sweet Mango Splash uses real broccoli — not an extract, not a derivative — and it tastes like mango, not like broccoli.
What makes young broccoli different from mature broccoli?
Young broccoli — both sprouts and microgreens — can be a far richer source of sulforaphane than mature broccoli. Sulforaphane is a crucifer-family compound (formed from a natural precursor, glucoraphanin) that researchers have studied for decades. The landmark work came from Johns Hopkins University, where Dr. Paul Talalay and Jed Fahey showed in 1997 that young broccoli sprouts can yield far more sulforaphane than mature broccoli heads (ScienceDaily, 1997).
The practical problem with fresh broccoli sprouts and microgreens: they have a 3-to-5-day shelf life. Sweet Mango Splash uses a dried, shelf-stable broccoli format instead — so it goes into the bottle without the short shelf window of fresh sprouts.
Where can you buy a functional beverage with broccoli in Virginia and nationwide?
Sweet Mango Splash ships nationwide via robbydslilgreens.com. It's also sold in person at select farmers markets in the Shenandoah Valley region of Virginia and the surrounding area, where Rob DeMariano sells it directly.
We're not aware of another shelf-stable, ready-to-drink beverage made from real broccoli. The drink is bottled in Frederick, Maryland.
Is Sweet Mango Splash friendly for people avoiding sugar?
Sweet Mango Splash contains no added sugar. It's sweetened with monk fruit and contains natural sugars from mango juice. It isn't labeled "sugar-free" because of the naturally occurring fruit sugars, but there are no refined sugars, high-fructose corn syrup, cane sugar, or artificial sweeteners in the formula.
The sweetness comes entirely from monk fruit and real mango juice — no synthetic sweeteners, dyes, or additives of any kind. No surprises on the label — every ingredient is something you can pronounce.
What is the shelf life of Sweet Mango Splash, and does it need refrigeration?
Sweet Mango Splash has a 2-year shelf life and does not require refrigeration. It's shelf-stable from production through storage and sale — a real distinction from cold-pressed juices, which typically have 30-to-90-day refrigerated shelf lives and need cold-chain logistics.
For retailers, shelf-stable means no shrink risk on a short cycle. For you, it means a bottle keeps in a pantry, packs in a bag, or ships without a cold pack.
