This site lists six specific items a transparent label should show, worth reading individually — starting with this first one: a complete ingredient list.
This site describes it directly: every active ingredient named, not hidden behind a vague blend description — worth reading this as the exact standard this site itself could not confirm SodaPeak meets, per its own admission elsewhere.
Worth noting this site places the ingredient-list item first among the six, ahead of serving size, manufacturer information, allergens, refund policy and marketing language — worth reading that order as this site's own stated priority.
