Daily needs are the starting point
EFSA’s population reference intake for protein in healthy adults is 0.83g per kilogram of body weight per day. That is a population reference, not a personalised sports nutrition prescription or a target for each snack.
For illustration, 0.83 multiplied by 70kg is about 58g per day. The calculation helps explain the reference; it does not tell every 70kg person exactly what to eat. Training, life stage and medical circumstances can change what guidance is appropriate.
Look at your usual meals first
Make a simple note of the foods you typically have for breakfast, lunch and dinner. You may already include several protein sources. A snack does not need to compensate for a gap that is not there.
If meals are irregular, improving the routine may be more useful than chasing a higher number on one packaged food. For personalised targets, especially around medical needs or demanding training, a qualified dietitian can put the whole day in context.
Compare the complete portion
Once you know why you want the snack, compare the amount you will eat. A smaller bar with less protein may still fit your appetite. A larger product can supply more while also being a different-sized snack.
Protein is one characteristic. Ingredients, allergens, energy, fibre, taste and price are worth considering too. A number that looks ideal on paper is less helpful if the product is unsuitable or you do not enjoy it.
Use the label as information, not a score
Henry’s current website lists 16g protein per 50g bar. That describes this product; it is not a recommendation that everyone should seek 16g in every snack. Check the current packaging when you receive your bars.
Choose a snack because it solves a practical need in your day. If you are hungry before a meal, away from your kitchen or looking for a convenient option, there are several ways to meet that need. A protein bar is one of them.
