Lean protein powders are fairly similar to standard protein supplements, except that they have a lower fat and lactose content. They come in both plant-based and whey formulas and are most commonly presented in WPI form, which is processed to contain less fat and calories than most proteins. These protein powders are usually lower in calories and are ideal for people sensitive to lactose or looking to lose weight (Tarrant, I. 2021).

Lean protein powders most commonly contain whey protein isolate because it is processed to contain fewer fats and lactose. Whey is the most common form of lean protein, but plant-based formulas utilise sources like pea protein, pumpkin seed & watermelon seed protein. 

These protein formulas will often contain vitamin & mineral complexes to enhance them, as well as digestive enzymes to work against bloating.

A lean protein powder can be beneficial if you’re sensitive to lactose or are working towards particular weight goals. These formulas are low in calories, carbs and fats and contain low lactose. Digestive enzymes are often included to prevent bloating, while some products contain thermogenic ingredients to facilitate weight loss. Lean protein powders remain high in protein while cutting down the lactose, fats and carbs that you may be trying to remove from your diet.

A lean protein powder is no less effective than a standard protein powder, delivering a high dose of quality protein but cutting out the lactose, fats and carbs that people may be looking to avoid in a supplement. These formulas are ideal for people looking to achieve specific weight goals or who have sensitivities to lactose.
