Macau Nutrition statement · Updated 14 November 2026
Whey price fluctuations mean our brand availability will vary from shipment to shipment. Some brands may be temporarily out of stock or return irregularly, while other trusted brands remain available.
Availability may change.
Quality stays the same.
Choose from our available whey brands for high-quality, complete protein at more favourable prices. Our standard is genuine whey, transparent ingredients and no amino spiking.
The Macau Nutrition statement
If your usual brand is unavailable, we recommend choosing from the quality whey brands we currently have in stock. We select these products to give you complete whey protein at a more favourable price, without compromising our standards or accepting amino-spiked products.
In the supplier offers we have recently received, some brands have increased their prices by more than 50%. Where the new cost no longer offers reasonable value, we are pausing selected purchases and prioritising other trusted brands, including supplier batches still priced before their latest increases.
This means a brand may be available now, temporarily unavailable later, and return when suitable stock and pricing become available. The next shipment may cost more, so we cannot promise the same selection or price every time. A purchasing pause is a decision about value, not a claim that the unavailable brand has changed its formula.
The brands on our shelves may change. Our commitment to genuine, high-quality, complete whey protein will not. Our team can help you choose an available alternative that suits your needs and budget.

Protein demand now goes beyond supplements
Major food and drink brands are bringing protein into more everyday products. Starbucks uses whey in its Protein Lattes and Protein Cold Foams; Danone’s Oikos Fusion drinks contain whey protein concentrate; and Nestlé developed a whey-based Boost Pre-Meal Hunger Support drink.
These launches illustrate a broader market, including interest in protein during weight management. They do not tell us how much any individual company has contributed to a price increase. Glanbia’s November 2026 update confirms significant whey cost inflation affecting its performance-nutrition business.
Why is whey supply limited?
Much of the whey used in supplements begins as a by-product of cheesemaking. More demand for protein drinks does not automatically create more demand for cheese.
Cheesemaking separates solid curds from liquid whey.
The whey is processed to separate and concentrate its proteins.
Concentrate or isolate becomes an ingredient for powders, foods and drinks.
Supply depends on both suitable raw material and processing capacity. Some whey, called native whey, is filtered directly from milk without cheesemaking; that route also requires dedicated processing. See Tetra Pak’s production guide.
Why does China still import whey?
China produces and consumes cheese, but its cheese-processing sector is relatively small compared with its demand for whey. This limits the amount generated by domestic cheesemaking.
Expanding supply needs investment, suitable raw material and facilities that consistently meet customers’ specifications. USDA’s June 2026 assessment identifies both limited cheese-processing scale and challenges with consistency and higher-specification products.
Production volume alone is not a judgment of an individual manufacturer’s quality. Our buying decisions focus on the actual product, its sourcing and transparent information.
Who makes the whey inside the tub?
The name on a retail tub is often different from the company that produces its whey ingredient. Examples of major ingredient suppliers with US production include:
These suppliers make the raw ingredients that manufacturers use in finished products. Brands may formulate and pack products themselves or work with manufacturing partners. A shared ingredient supplier does not make every finished formula identical.
Genuine whey has a real raw-material cost. A different label cannot remove that cost, whether the ingredient is bought from a supplier or produced within the same business.
Why can one brand still cost less?
Brands face the same broad ingredient market, but they do not all pay the same invoice price. Purchase volumes, contract timing, older stock, ingredient specifications, freight, overheads and margins can create legitimate differences.
Changing the protein blend is another way a product’s cost and nutritional profile can change. If a formula includes collagen or other protein sources, customers should be able to identify them clearly.
A low price does not prove adulteration, and a smaller brand does not have to dilute its formula to be profitable. We compare what is actually in the product, not just its price or brand size.
Read the source, not just the protein number
Some bars, ready-to-drink beverages and powders use collagen as all or part of their protein. For example, Barebells identifies bovine collagen in its original and soft bars, while Vieve identifies collagen as the protein in its water drinks. These are examples of declared ingredients, not evidence of amino spiking or a recent formula change.
20 g protein ≠ 20 g whey
The total tells you how much protein is declared. The ingredients tell you where it comes from.
How can collagen count as protein?
Collagen is protein, so it can contribute to declared protein grams. That does not give it the same amino acid profile or muscle-building response as whey.
For example, US Nutrition Facts rules allow protein grams to be calculated from measured nitrogen using a conversion factor, usually 6.25 unless the specified method requires another factor. Protein % Daily Value uses a separate correction for digestibility and amino acid quality. When a protein claim is made, that corrected % Daily Value is generally required. Rules vary by market; total grams and protein quality are different measures. FDA explanation · US labeling rule.

collagen protein=20 g
total protein
Illustrative composition only, not a claim about any named product or its legally permitted label. The blend contains 12 g of whey protein, not 20 g.
| What matters | Whey | Collagen alone |
|---|---|---|
| Essential amino acids | Contains all nine | Lacks tryptophan |
| Leucine | Relatively rich | Much lower |
| Muscle-building comparison | Greater muscle protein synthesis in a direct trial | Not an equivalent gram-for-gram substitute in that trial |
A controlled trial in older women found a greater muscle protein synthesis response with whey than collagen. A separate 10-week trial in young adults found greater gains in muscle thickness with whey than leucine-matched collagen, with similar strength and power changes. These results do not mean collagen has no uses; they explain why the proteins should not be treated as interchangeable for muscle-building goals. 2020 trial · 2022 trial.
Look for the named protein sources. A clearly labeled collagen blend is a different product from whey. Its presence alone is not deception; presenting it as equivalent to an all-whey formula can leave customers with the wrong impression.
No amino spiking. No disguised substitutions.
Our policy is to reject products that misrepresent their whey content. We will not accept free amino acids, collagen or other cheaper ingredients being used to disguise a reduction in the whey customers expect.
Amino spiking concerns misleading protein figures produced with added amino acids or other nitrogen-containing ingredients. A basic total-nitrogen test alone cannot establish how much intact whey protein a product contains; specialist analysis can examine its amino acid profile and free amino acids. BSCG explains the testing distinction.
Clearly labeled collagen and amino-acid products have their own place. Our standard is honest composition and clear information about what you are buying.
Our outlook: buy for quality and value
We expect prices and availability to remain uneven across suppliers, brands and batches in the near term. This is our purchasing outlook, not a prediction of when prices will peak. We will keep comparing actual offers and buying when quality and price make sense together.
If your usual product is unavailable, compare the protein source, protein per serving, net weight, number of servings and cost per serving. Both whey concentrate and isolate can be suitable choices, depending on the product and your needs. Whey is milk-derived and unsuitable for people with a milk-protein allergy. More about whey.
