About The Lean Protein

The Lean Protein is a protein powder blend designed for adults who want a high‑protein supplement to support muscle maintenance whilst losing weight.

Each standard serving provides 31 g of protein, which contributes to the growth and maintenance of muscle mass and bones. The Lean Protein mix also includes inulin, acetyl‑L‑carnitine and selected plant extracts (pomegranate, yerba mate and bilberry) for those who prefer a more complex, supportive blend.

While protein powders are not a substitute for a balanced diet, they offer a convenient way to help you meet your protein needs. The Lean Protein delivers a higher level of protein per serving than many similar products, with a substantial 31 g of protein in each 40 g dose.

Please note: this is not a weight‑management product. The Lean Protein will not cause weight loss, though it may be used to support people who are using other evidence-based methods of weight loss.

How much protein do I need?

International guidelines state that the average adult needs around 0.8g of protein per kilogram of bodyweight each day. Some people may need more of less than this, depending on their body size, overall health and activity levels. The Lean Protein is intended to supplement the protein you get from food, not to replace dietary sources of protein.

Is this a meal replacement?

No. The Lean Protein is not designed to be used as a meal replacement. Relying on it instead of meals could mean you miss out on important nutrients found in a balanced diet.

What alternatives are there for protein?

Common dietary sources of protein include lean and red meats, poultry, fish, seafood, eggs, milk and other dairy products. Plant-based options such as beans, lentils, tofu, tempeh, nuts and seeds can also provide good amounts of protein.

How do I get my protein shakes smooth?

To get a smooth blend, many people find a shaker bottle with a wire ball whisk is a convenient way to prepare their protein shake. You could also try a whisk, blender or smoothie maker to break up any clumps. After mixing, let the shake stand for a minute to help the powder dissolve further and improve the texture.
