Flagged as a product to avoid

1 of 11 research runs entered this as a product to avoid rather than a pick.

As an effervescent tablet it delivers a fraction of the electrolyte payload of the leading powders, so for anything beyond a casual walk it is outclassed at its use case. Nuun Sport Powder or Skratch Labs Hydration Everyday Drink Mix do the same job with better consensus behind them.
