‘Good for you’ isn't a single number — it depends on what you're comparing against and what specifically you're checking for. Here's how to actually evaluate a vanilla protein powder rather than take a marketing claim at face value.
Sugar content

Flavoured protein powders will always carry some sugar to make the vanilla taste genuinely pleasant rather than bitter or flat. The number that matters is the actual sugar-per-serve figure on the nutrition panel — compare it against other flavoured protein products, not against an unflavoured protein isolate, which isn't a fair comparison.
Additives

• Check the ingredient list for what's actually flavouring the vanilla — natural vanilla flavour versus a long synthetic additive list tells you a lot about formulation philosophy.
• Look for what's absent as much as what's present — GC Proteins' badges (No Artificial Colors/Flavours) are a specific, checkable claim, not vague marketing language.
• Thickeners, gums and anti-caking agents are common and generally unremarkable in small amounts across the category — the question is whether the list is reasonable or excessive.
Calories

A protein powder's calorie count is mostly a function of protein and carbohydrate content per serve — there's no universal ‘good’ number, only whether it fits your own daily calorie goals. Compare per-serve calories against per-serve protein delivered, not in isolation.
The honest verdict

A well-formulated vanilla protein powder, checked against its own nutrition panel rather than assumed from marketing language, is a reasonable addition to most balanced diets. The details that actually matter — sugar, additive list, calories relative to protein delivered — are all sitting right there on the pack, not hidden.
