FAQs

Are protein bars healthy?

Protein bars can be a convenient and nutritious snack option when chosen wisely, but not all protein bars are created equal! Whilst many are packed with essential nutrients and can support a healthy lifestyle, some can have high levels of sugar and saturated fat. Instead, look out for low-sugar protein bars or those that have a good balance of protein, fibre, and healthy fats. Protein bars can be a great way to fuel your body, aid in muscle recovery, and satisfy hunger on the go, making them a healthy choice when selected mindfully.

When should you eat a protein bar?

Wondering whether you should have a protein bar before, during or after your workout? Here’s what our in-house registered nutritionist, Holly Roper, says: “When it comes to eating protein bars, it's all about what works best for you. Here are our suggestions on when to munch on a protein bar: - Grab a protein bar in the late morning to give yourself a boost of energy and keep those hunger pangs at bay until lunchtime. - After your workout, chow down on a protein bar to help your muscles recover. - If you want a little extra oomph before hitting the gym, have a protein bar beforehand to give yourself a nice energy kick.”

Is it OK to eat protein bars everyday?

Eating protein bars daily can be part of a balanced diet, but it's essential to consider them as a supplement rather than a meal replacement. Choose bars with high-quality protein sources, limited added sugars, and minimal artificial ingredients. Variety in your diet is key to obtaining a wide range of nutrients.

What are the healthiest protein bars to eat?

The healthiest protein bars are those made with natural ingredients, a balanced macronutrient profile, and minimal added sugars. Look for bars with high-quality protein sources like whey, soy, or pea protein, and avoid those with excessive additives or artificial sweeteners. Some brands offer organic or vegan options for added health benefits.
