Science in Sport Rego Choc and Protein Bar



Easy-to-eat bar to help muscle recovery after exercise, with a good mix of carbs and proteins. Very tasty too.

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

A new addition to the SiS portfolio of nutrition products is this Rego Protein Bar. With a mixture of carbs and proteins, it's designed to help muscle recovery after exercise. And with ingredients including chocolate and peanuts, it's tasty too.

Most sports scientists agree that after training you can help your muscles recover (and be stronger next time) by taking on some protein as well as carbohydrate. The Rego Protein Bar helps you do this by providing 21g of carbohydrate and 20g of protein in a 55g bar. For the record, there's also about 6g of fat (3g unsaturated, 3g saturated) plus a dash of fibre and sodium.

The ingredients include milk, milk derivatives (whey, casein), wheat gluten, soya and peanuts. The bar is also coated in chocolate.

The formula is very similar to another SiS product called Build Bar, which now seems to be discontinued. Or maybe it's the same stuff with a different wrapper, renamed to fit in with the range of other Rego (post exercise) products.

Either way, without doubt, this Protein Bar is very tasty. It's sweet, but not overly so, and not sticky. The most familiar taste is the chocolate in the coating, but you also get a hint of the peanuts included in the main part of the bar.

The texture is chewy, and this bar definitely needs liquid to help it go down, but as it's designed for eating after a race or work-out, having plenty of drink to hand won't be a problem.

The SiS website also suggests that the Rego Protein Bar can be eaten "throughout the day between meals (such as mid-morning and mid-afternoon snacks) to provide a convenient way to increase daily protein intake". Nothing wrong with that, but there are also other ways to increase protein intake if that's your aim. It might be more useful to regard a Protein Bar as a healthier alternative (because it has less refined sugar and less saturated fat) to a cake or normal confectionary bar with your mid-morning coffee at work.

Of course, you don't have to eat designated protein bars to help muscle recovery after exercise. A bowl of muesli, peanut butter sandwich or chicken pasta dish will do more or less the same job. But a lot depends on what you feel like eating immediately after a big cycling event or tough training session. For me, one of these SiS protein bars with a cup of tea hits the spot immediately after a long ride, soon followed by that bowl of muesli, with the chicken pasta not far behind.

On price, the SiS Rego Protein Bar retails at £1.99 at your local bike shop or the usual on-line stores. On the SiS website it's a penny under £40 for 20 bars (currently discounted to £35.82). This is not cheap, but it's on a par with similar products from other manufacturers.

Tell us what the product is for, and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?

This product is a recovery bar, designed to provide protein and carbohydrates after exercise, to help your muscles recover. The SiS websiste says: "SiS REGO Protein Bars contain a blend of easily digestible proteins (20 grams of protein per bar) in the form of whey, casein and soy protein. Sports scientists are increasingly recognising the importance of consuming protein in close proximity to training sessions (i.e. before or after training) in order to maximize how our muscles adapt to training."

Tell us some more about the technical aspects of the product?

The SiS website goes on to say: "Adapting to the demands of endurance training is facilitated by increased muscle protein synthesis whereby new proteins (such as enzymes involved in energy production and proteins which give muscle structure) are made in our muscles during the hours and days after each training session. As such, the muscle becomes reconditioned so that it can better withstand the physical demands that are placed upon it during the next training session."

Rate the product for performance:

Performance is very good in that the bar has a mix of carbs and protein that's tasty and easy to get down after a long hard ride.

Rate the product for weight, if applicable:

55g is about par for a bar of this type, but you're not carrying it on a ride, so weight is largely academic.

Rate the product for value:

At almost two quid a shot, this SiS Rego bar isn't a bargain. The price is at the slightly high end of the range compared to similar protein/recovery products from other manufacturers such as PowerBar Protein (15 bars for £30, discounted to £20 in some stores), High 5 Protein (25 bars for around £40), ZipVit ZV9 (15 bars for £25) and MuleBar Refuel (24 bars around £40). Prices are approximate and sizes vary slightly (eg, ZipVit and MuleBar are 65g, High5 is 50g).
