The benefits of making your own protein bars – and two easy recipes

23 Nov 2022 • 1 min read

More and more people are discovering the benefits of making their own protein bars at home. Try it – you may never go back to buying them!

3 benefits of making your own protein bars 

  1. You can control what goes in them
Make your own protein bars at home and you’ll have full control over the ingredients, so surprises like high fructose corn syrup and fractionated palm kernel oil won’t sneak in. Also, as your homemade bars don’t need to sit in warehouses and shops for weeks, you won’t need to use additives.
  1. You can tailor them to your taste
Hate honey? Love dates? Adore cashews but loathe almonds? You don’t have to hope your favourite brands come up with the combination of your dreams when you can invent it yourself. If you have special dietary requirements, you can cater to these, too. For example, homemade low carb protein bars or gluten free protein bars offer you the reassurance you need. The beauty of making your own protein bars is that most recipes don’t involve baking, so you don’t have to be scientifically accurate with your quantities or risk ruining a batch. No-bake recipes are customisable. As long as you’re getting the texture right, you can play with flavours.
  1. You’ll save money
Protein bars can be pricey, with many bars costing around £3 each. Although the initial outlay is a factor, if you can get hold of a bag of oats, some nuts and seeds and protein powder, the other ingredients are generally made up of storecupboard staples like honey and salt. If you eat a protein bar most days, you’re saving around £20 per week with homemade rather than shop-bought.

How long do homemade protein bars last? 

Homemade protein bars don’t keep as long as the ones you buy. If stored in a non-airtight container, homemade protein bars will be past their best after about 3 days.

What is the healthiest protein bar on the market? 

If you’re aiming to lose or maintain weight, look for a bar with lower calories, lower fat and lower carbohydrates. If you’re gaining weight, go for a higher-calorie bar. Shop Sports Nutrition Last Updated: 5th January 2021
