Kirkland Signature Sparkling Water, Variety Pack (Flavored) — DUMP

Munch or Dump rates Kirkland Signature Sparkling Water, Variety Pack (Flavored) by Kirkland Signature DUMP — score 17/90.

This gets shelved next to LaCroix, but the ingredient list tells a different story: it is sweetened with sucralose and tinted with a stack of artificial dyes (Red 40, Blue 1, Yellow 5, Yellow 6) plus a preservative. That is not clean sparkling water, it is a zero-calorie diet soda in disguise. The added B-vitamins and green tea extract are a health-halo garnish, not a reason to drink it.

Why this verdict

• Artificially sweetened with sucralose
• Contains four synthetic dyes: FD&C Red 40, Blue 1, Yellow 5, Yellow 6
• Potassium benzoate preservative and ester gum weighting agent
• NOVA 4 ultra-processed formulation, not plain seltzer

Ingredients (11)

• Carbonated Water (safe) — Basic component of most beverages, provides fizziness.
• Citric / Malic Acid (safe) — Common acidulants for tartness. Benign.
• Natural Flavors (safe) — Flavor compounds derived from natural sources.
• Sucralose (moderate) — Artificial sweetener; unexpected in a bakery pie and a second sweetness source.
• Green tea leaf extract (safe) — Trace antioxidant/functional garnish. Present in tiny amounts for marketing appeal.
• Added B-Vitamins (niacinamide, B12, B6, biotin, pantothenate) (safe) — Synthetic fortification. Harmless but a health-halo touch, not a real nutritional benefit here.
• Ester Gum (moderate) — Glycerol ester of wood rosin used to keep flavor oils suspended. An industrial weighting agent, not a kitchen ingredient.
• FD&C Yellow No. 5 (tartrazine) (avoid) — Synthetic azo dye linked to hyperactivity signals in sensitive children; purely cosmetic.
• FD&C RED NO. 40 (avoid) — Petroleum-derived synthetic dye. No nutritional purpose; flagged in behavioral studies.
• FD&C Blue No. 1 / Yellow No. 6 (caution) — Additional synthetic colors used purely to make the water look fruity.
• Potassium Benzoate (moderate) — Preservative; can form trace benzene with ascorbic acid/heat. Common but marks a processed drink.
