Precision Protein Dosing: Whey & Plant Protein

Updated August 30, 2026

How much protein do you need, and how much of your chosen powder helps you reach it? Start with your total daily intake, consider the protein already in each meal, and use the serving information for your exact product.

The TLC Precision Dosage Calculator brings these pieces together for all six TLC whey and plant proteins. It provides an evidence-informed starting point—not a measurement of your individual biological requirements or a medical prescription.

Protein from food and supplements contributes to the same daily total. Your needs depend on factors including body size, activity, resistance training, age and health. Protein powder fills a gap; it does not need to supply the whole target.

In healthy adults undertaking resistance training, Morton and colleagues found that additional muscle gains from protein supplementation levelled off, on average, around a total intake of 1.6 g/kg/day. This is a population estimate, not an exact requirement or a safety limit for every person. The study's uncertainty range also matters when interpreting higher calculator targets. [1]

Older adults and people recovering from illness may need a different approach. Age-related anabolic resistance means muscle can respond less strongly to a given protein intake, but there is no single birthday when this suddenly begins. Illness, frailty and rehabilitation require individualized clinical judgement—not simply the largest number the calculator can display. [2] [3]

The current calculator uses your current body weight through BMI 30. Above that point, it uses the weight corresponding to BMI 30 at your height unless you select the muscularity override. When a cap is applied, the results show the reference dosing weight.

This is a pragmatic calculator rule to limit overestimation when a higher weight includes substantial body fat. It is not a measurement of lean mass, an “ideal weight,” a weight-loss goal or a universally validated clinical dosing threshold. BMI cannot distinguish muscle from body fat, which is why the muscularity option is included. A clinician may choose a different weight basis in an individual case.

Leucine is an essential amino acid involved in the signalling that stimulates muscle protein synthesis. The rest of the essential amino acids provide necessary building material too: leucine alone does not replace an adequate protein intake.

Meal targets can help you plan enough high-quality protein, especially when appetite is limited or meals contain little protein. Older muscle may require a larger relative protein intake to produce a comparable response. However, the response depends on the person, the meal and recent exercise; the age bands and leucine estimates in the calculator are practical approximations, not laboratory measurements of your personal threshold. [2]

Protein above a meal target is not automatically wasted. In a controlled study of healthy young men after exercise, 100 g of protein produced a larger and longer-lasting anabolic response than 25 g during a 12-hour assessment. That acute finding does not establish that 100 g meals are necessary, practical or superior for long-term muscle growth. It does show why a strict per-meal ceiling is too simplistic. [4]

A scoop measures powder, not pure protein. Flavours and protein sources differ, so an age-only scoop chart cannot reliably describe all six products. The calculator uses the selected product's composition to estimate an appropriate serving.

Each labelled serving is 40 g powder, approximately 2 level scoops:

• Double Cocoa: 27 g protein per serving.

• Heritage Vanilla Bean Spice: 27 g protein per serving.

• Unflavoured: 32 g protein per serving.

Each labelled serving is 30 g powder, approximately 2 level scoops:

• Double Cocoa: 20 g protein per serving.

• Heritage Vanilla Bean Spice: 20 g protein per serving.

• Unflavoured: 24 g protein per serving.

These are labelled serving amounts, not a recommendation that everyone needs a full serving at every meal. Follow the current label on your bag and the matching calculator selection. Scoops are approximate; weighing the powder gives a more consistent portion.

Your meal target includes protein from the shake, milk or other mixing liquid, and any food eaten with it. If food already supplies enough protein, additional powder may not be needed.

For example, if a calculated dose provides approximately 21 g protein and the meal target is 20–25 g, you have already reached the lower end. Another 0–4 g of protein from food would place the meal within that range. The extra 4 g is optional—not an amount everyone must add.

A displayed serving range is a planning aid, not proof that the upper amount is biologically optimal. Choose an amount that fits both the meal and your overall daily intake. Whole foods should remain the foundation of your diet.

Keep approximately the same daily protein target on rest days: recovery continues between workouts. On training days, spreading protein across three or four main eating occasions is a practical way to build a manageable routine; include a protein-containing meal within a few hours before or after training when convenient.

Divide your daily target by the number of eating occasions you realistically prefer, then adjust portions for your appetite and meals. A per-meal range is not a cap: some meals may need more protein to reach the daily total. A protein-rich snack can also help.

There is no requirement to eat four or five meals every day. Fewer meals can work, and the long-term benefit of one specific distribution pattern is not settled. Prioritize adequate daily protein and consistent resistance training, with a meal pattern you can sustain. Rest days allow flexibility without making meal quality irrelevant. [1] [4]

We deliberately use non-instantized whey without added lecithin or anti-caking agents. Research on soy lecithin has identified changes in microbial metabolites, but the clinical significance remains uncertain. These findings do not establish that lecithin damages the gut.

Because added lecithin is not necessary for our formulation, we choose to leave it out while the evidence develops. This is a precautionary formulation choice—not a claim that lecithin-free protein has proven superior gut-health outcomes.

The practical trade-off is that some clumping may occur, and more vigorous shaking, blending or a brief rest may be needed. Follow the mixing and storage directions on your chosen product.

Human trial: Wellens et al., 2026, Clinical Gastroenterology and Hepatology. PMID: 40816342.

This is a formulation and mixing trade-off. Clumping alone is not proof of purity or a gut-health benefit, and easy mixing is not proof that another product contains lecithin. Check the ingredient information rather than judging a powder by how quickly it dissolves.

Use the calculator to estimate a daily target, select the right product and work out how a supplement fits your meals. Combine adequate protein with resistance training and adjust the plan to your circumstances. “Precision” here means clearer, product-specific guidance—not an exact biological dose that guarantees a result.
