Our verdict
TREK by a nose — but don't buy either for protein
Let's be direct: 9.5g and 7.7g protein per serving, both over 11g sugar, both graded D (34 vs 32). These are oat-and-fruit bars with protein aspirations, not protein bars. If protein is the job, every bar in waves 1–2 beats both.
Between the two, TREK takes it on the only line that matters here: more protein per bar (9.5g vs 7.7g) and per 100g (19g vs 17g), for a nearly identical sugar load. Marginal, but real.
Nakd's consolation prize is genuine: a Clean Score of 100 — the only perfect score in this wave, and one of very few in the catalog. If your priority is a short, natural ingredient list rather than protein, Nakd is the pick.

Who should buy which
Buy TREK if…
You want the flapjack format and the slightly better protein of the two — 9.5g per bar with a 96 Clean Score. A decent oat bar that happens to have some protein.
Buy Nakd if…
Ingredient purity is your thing — a perfect 100 Clean Score from dates, peanuts and natural flavourings. Just don't pretend the 7.7g protein is the point.
Frequently asked
Are TREK and Nakd bars good for protein?

Which is healthier, TREK or Nakd?

Why is Nakd's Clean Score 100?
Its ingredient list is essentially dates, peanuts and natural flavourings — nothing to penalise. One of the few perfect scores in the catalog.
