If protein per bar is the recipient’s main priority, TREK lists 16g in its Biscoff High Protein Bar and 15g in its Choc Peanut Butter High Protein Bar, both weighing 55g. A smaller gluten-free Nature Valley bar or a vegan nākd. fruit-and-nut bar may fit different preferences; check the exact pack’s ingredients and allergen warnings before gifting.
For a dad or father figure who takes a snack to work, on a journey or after exercise, compare the labelled protein amount per bar alongside its weight. A protein claim alone does not tell you how much one bar provides.
If the recipient prefers vegan, gluten-free or dairy-free food, check those claims on the exact flavour. They do not establish that a bar is free from peanuts, other nuts or soya.
Protein may be the starting point, but sugars, energy, fibre, ingredients and portion size can also affect which bar they would choose.
Start with the amount in one labelled bar, then check whether its ingredients, portion and flavour suit the recipient.
| Priority | What to check | Your needs |
|---|---|---|
| Protein per bar | Read the grams per bar and its weight, rather than comparing protein claims alone. TREK lists 16g per 55g Biscoff High Protein Bar and 15g per 55g Choc Peanut Butter High Protein Bar; Nature Valley lists around 10g per 40g Salted Caramel Nut bar. | I want to know what one bar provides, particularly if the recipient prefers a smaller snack. |
| Ingredients and allergens | Check the exact flavour’s ingredients, dietary claims and “may contain” statement. The bars discussed here variously include or warn about peanuts, other nuts, soya, milk and wheat. | The gift needs to fit the recipient’s dietary requirements; a vegan or gluten-free label does not answer every allergen question. |
| Sugars and fibre | Compare the stated amounts per bar on the current pack. “No added sugar” describes added ingredients; it does not mean a bar contains no sugars. | Protein matters to me, but I also want the other nutrition figures to fit the recipient’s preferences. |
| Format and flavour | Check whether the gift is a coated bar, an oat flapjack or a fruit-and-nut bar, and confirm the flavour and number of bars in the pack. | A format the recipient enjoys may matter more than choosing by protein grams alone. |
TREK lists 16g protein per 55g Biscoff High Protein Bar, while the Tesco listing for nākd. Peanut Butter Protein gives 7.6g per 45g bar. They serve different protein-per-bar preferences.

Check the exact current pack against the recipient’s requirements before giving it as a gift.
TREK lists 14g sugars per 50g Cocoa Oat flapjack and 2.3g per 55g Choc Peanut Butter High Protein Bar. Their formats and serving weights differ, so the flapjack label is not a shortcut to a sugar comparison.

Joybuy describes a TREK Biscoff Flapjack as a 50g bar with 9.8g protein; TREK’s Biscoff High Protein Bar is a different 55g bar listing 16g protein.
