5 of the best low-sugar protein powders



If you’ve ever stood in the supplements aisle (or scrolled online) and felt overwhelmed by the wall of protein powders, you’re not alone. Between flashy packaging, confusing nutrition labels and endless promises, it’s hard to know which one is actually worth adding to your routine.

One simple rule I like to follow is to keep an eye on the sugar content. While protein shakes can be a great way to boost recovery after a workout, keep you fuller for longer, or just help you sneak in extra nutrition, a lot of powders are packed with unnecessary sweeteners. Luckily, there are some brilliant low-sugar options that don’t compromise on taste or quality. 

But first, let’s take a look at why excess sugar in protein powders should be avoided.

Why should you avoid excess sugar in protein powder?

Excess sugar in protein shakes can undo many of the health benefits you’re trying to get from them. While a little sugar is fine, regularly consuming shakes that are high in added sugar can lead to blood sugar spikes and crashes, which may leave you feeling tired or craving more sweet foods. 


Over time, too much sugar contributes to weight gain, insulin resistance, and a higher risk of conditions like type 2 diabetes and heart disease. It can also undermine the reason you’re taking protein in the first place (whether that’s for the gains, muscle recovery, steady energy, or overall health) by adding empty calories that don’t provide the nutrients your body actually needs.


Here are five protein powders to consider if you’re looking for lower sugar options.

Naked Nutrition Whey Protein
Naked Nutrition Grass Fed Whey Protein Powder (£79.99 for 2280g)

If you like your supplements stripped back and simple, Naked Whey might just be your match. It’s sourced from small non-GMO dairy farms, with cows that are grass-fed, free-roaming, and raised without hormones like rBGH or rBST. Each serving delivers an impressive 25g of protein along with 5.9g of BCAAs, without any additives, fillers or artificial sweeteners. Naked Nutrition keeps things clean and transparent, so what you see really is what you get.

The coconut sugar adds a touch of sweetness (still just 2.6g per serving), while the vanilla flavour makes it feel like more of a treat than a supplement. Buy it here.
