Gym-goers wanting a chocolate treat
A finished bar is convenient to take with you after exercise. If you also want a protein-containing food or drink, plan for that separately rather than relying on the chocolate.
Who is a single bar for?
Shoppers who prefer a defined portion
A 25g or 35g single bar lets you finish one pack. A 90g or 100g tablet calls for you to decide how much to break off and keep the rest for later.
Buyers checking ingredients and dietary labels
Vegan claims, cocoa percentages and stated sourcing may help narrow the choice. If allergens matter, read the current pack’s ingredients and warnings as well: a vegan-labelled bar can still carry trace warnings.
What should you check before choosing?
Start with whether you want to finish one small bar or portion a larger tablet, then compare the serving information and ingredients on the pack.
| Priority | What to check | Your needs |
|---|---|---|
| Portion size | Check the pack weight and whether it is one finished bar or a tablet to divide. Montezuma’s FitzRoy is 25g; Divine’s 70% single bar is 35g. | I’d rather finish a small bar than decide how many pieces to take from a larger pack. |
| Protein per bar | Compare protein for the amount you intend to eat, not just per 100g. Montezuma’s and Divine’s declared values work out at about 2.5g per 25g FitzRoy bar and 2.9g per 35g Divine bar. | If I want a protein-containing food or drink after exercise, I’ll choose it separately from the chocolate treat. |
| Cocoa and nutrition | Check cocoa percentage alongside the nutrition panel and serving size. FitzRoy is described as 74% cocoa and Divine’s single bar as at least 70%; cocoa percentage alone does not tell you the nutrition of the portion you eat. | I have a cocoa preference, but I also want to compare the actual portion before choosing. |
| Allergens | Read the current ingredients and allergen warning, even if the product is described as vegan. The FitzRoy and Divine single bars carry warnings for possible allergens. | When an allergen matters to me, the current pack declaration takes priority over a vegan label. |
| Ingredient preferences | Check the specific pack for stated Fairtrade, organic or other ingredient claims; these vary by product and format. | I’d like to choose on the basis of a particular stated ingredient or sourcing preference, as well as portion size. |
What is easy to overlook?
-
Treating the chocolate as the protein part of the snack
Montezuma’s and Divine’s declared nutrition works out at about 2.5g protein in the 25g FitzRoy bar and 2.9g in the 35g Divine bar. Those figures describe the chocolate, not a complete post-exercise food choice.
Choose the bar for its portion and ingredients. If you also want a protein-containing food or drink after training, choose that separately.
-
Comparing whole bars as though they were one portion
A 25g mini bar and a 100g tablet are different pack formats. Nutrition per 100g can help you compare products, but it does not describe what you will eat unless your portion is 100g.
Check the stated serving and decide how much of a larger tablet you intend to eat before comparing it with a single bar.
-
Reading ‘vegan’ as ‘allergen-free’
The FitzRoy and Divine single bars are described as vegan but carry warnings for possible allergens, including milk or nuts.
If you need to avoid an allergen, check the declaration on the current physical pack rather than relying on the vegan description.
Which brands offer relevant formats?
Montezuma’s
Its FitzRoy Organic 74% Dark Chocolate Mini Bar is a 25g finished bar; Absolute Black is a separate, larger 100% cocoa product.
- The FitzRoy format gives you one small bar without dividing a tablet.
- The FitzRoy bar may contain traces of milk, nuts and peanuts. Do not assume the larger Absolute Black tablet has the same portion or ingredients.
Divine
Divine’s 70% Dark Chocolate 35g is a finished single-bar option; the brand describes its cocoa and sugar as Fairtrade.
- The 35g format suits someone who wants a larger finished bar rather than a tablet to divide.
- The single bar may contain milk, gluten and nuts. Check the exact product: Divine’s raspberry 90g bar is a different variant.
Green & Black’s
A 35g Organic 70% Dark Chocolate product is listed separately from the brand’s 90g 70% tablet.
- The listed 35g format is relevant if you want one finished bar.
- Check the current pack for the 35g bar’s nutrition rather than applying values from the separate 90g product.
Lindt
Lindt EXCELLENCE Dark 78% is a 100g tablet for shoppers who want to choose their own portion.
- The stated 78% cocoa content helps identify this particular variant.
- It is not a finished small portion, and its product information warns of possible nuts, milk and soya.
M&S
M&S lists an 85% dark-chocolate bar in a 100g format.
- The stated cocoa percentage and pack weight make it possible to identify the tablet you would be portioning.
- M&S says this product is not suitable for people with milk, nut or peanut allergy.
Hotel Chocolat
Its dark-chocolate range includes selector and slab formats, with listed 70%, 80% and 85% options.
- These formats offer a different way to choose dark chocolate by product and cocoa percentage.
- Check the weight and nutrition of the particular selector or slab before comparing a portion with a 25g or 35g single bar.

Choose your own portion from this raspberry-containing tablet if a finished single bar is not important to you. The 90g bar states at least 70% cocoa and 3% freeze-dried raspberry pieces. Its vegan-friendly description conflicts with milk listed in the ingredients and allergen information: check the current pack before buying it for a vegan diet or an allergy.
Questions about post-gym dark chocolate
Can a dark-chocolate bar be my only post-gym snack?
It can be the chocolate treat you choose, but do not count on these single bars for much protein. Montezuma’s declared values work out at about 2.5g in its 25g FitzRoy bar, and Divine’s at about 2.9g in its 35g bar. If you also want a protein-containing food or drink after exercise, choose one separately.
Which format avoids dividing a larger bar?
The 25g Montezuma’s FitzRoy mini bar and 35g Divine 70% bar are both finished single bars. If you choose a 90g or 100g tablet instead, decide how much you intend to eat and compare nutrition for that portion.
Does a higher cocoa percentage settle the choice?
No. Cocoa percentage identifies an aspect of the chocolate, but it does not tell you the pack size or the nutrition of the portion you will eat. Check the serving information, full nutrition panel and ingredients on the particular bar.
Does a vegan label mean the bar has no milk or nut warning?
No. The vegan-described Montezuma’s FitzRoy bar may contain traces of milk, nuts and peanuts, while Divine’s 35g bar may contain milk, gluten and nuts. Read the current pack’s allergen declaration if you need to avoid any of these ingredients.
