Cricket Protein vs Whey Protein: How Do They Really Compare?

Whey has been the default answer to "what protein should I take?" for about two decades. It is cheap, it mixes into a shake, and the research behind it is deep. So when a cricket protein snack turns up on the shelf next to it, the honest question is not "is this trendy?" — it is "does it actually stack up?"

Here is what the research says about cricket protein vs whey protein, where whey clearly wins, where crickets quietly hold their own, and why the comparison matters more in Singapore than you might think.

Cricket protein vs whey protein: the amino acid scorecard

A protein source is only as useful as the amino acids it delivers. On this measure, both pass the basic test. A 2024 study published in Molecules compared commercially available cricket protein powder against whey protein and found that both contained all the essential amino acids, with leucine — the amino acid most associated with triggering muscle protein synthesis — the most abundant essential amino acid in both samples.

The quantities, though, are not identical. The researchers calculated an essential amino acid index (EAAI) of 79% for cricket protein powder versus 94% for whey when using crude protein as the basis. Cricket protein powder also came in with slightly less protein and more fat than whey.

Translated out of lab-speak: whey is the more concentrated, more perfectly balanced protein. Cricket protein is a genuinely complete protein that sits a step behind it. That is a much stronger showing than most people expect from an insect.

What about digestibility?

This is where whey's reputation is earned. In the same Molecules study, cricket protein's digestibility climbed gradually through intestinal digestion to reach nearly 80%, while whey protein surpassed 97%. The authors were clear about what that means, though: despite the lower figure, cricket protein digestibility "remains sufficiently high for consideration as a valuable protein source."

So: whey is faster and more completely absorbed. Cricket protein is slower and slightly less so — which, for a snack you eat between meals rather than a post-workout shake, is not the disadvantage it first appears to be.

The dairy problem nobody mentions in the shaker aisle

Here is the part of the whey story that gets skipped in Singapore. Whey is a milk protein, and lactose comes along with the territory in many whey products. According to the US National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), lactose malabsorption is far from evenly distributed around the world — in Africa and Asia, most people have it, while it is least common among people of European descent.

Not everyone with lactose malabsorption gets symptoms, and most people who do can still handle some lactose. But if you have ever finished a protein shake and spent the next hour bloated and gassy, you now have a plausible explanation — and a reason to look at protein sources that were never dairy in the first place.

Cricket protein is naturally dairy-free and lactose-free. That is not a marketing angle; it is just what it is.

How much protein do Singaporeans actually need?

Before anyone panic-buys a tub of anything, it is worth checking the target. HealthHub, run by Singapore's Health Promotion Board, puts the recommended daily protein intake for adults aged 18–49 at roughly 0.8g per kg of body weight — about 50g to 60g a day for the average Singaporean adult. Adults aged 50 and above need more, at around 1.2g/kg, to help hold off the muscle loss that can start as early as 40.

HealthHub's own advice is refreshingly unglamorous: spread protein across your meals, mix animal and plant sources, and — pointedly — "replace your chocolates or chips with low-fat yogurt or unsalted roasted nuts during snack time." The gap for most people is not the gym shake. It's the 3pm snack.

Is cricket protein safe and legal in Singapore?

Yes. The Singapore Food Agency (SFA) has approved 16 insect species for human consumption and animal feed under a regulatory framework that requires the species to be assessed as safe, farmed in a controlled environment rather than harvested from the wild, and raised on clean substrate — no manure, no rotten food. Imported insect products and local insect farms are subject to regular inspection and sampling.

One important caveat, straight from SFA: people with shellfish and crustacean allergies may also react to insects, because some of the same allergenic proteins are present. If that is you, give cricket protein a miss.

So which one should you actually eat?

They are not really competing for the same job. If you want the fastest, most concentrated hit of protein after a heavy training session, whey remains hard to beat on the numbers. But if what you actually need is a protein-containing snack that isn't a bag of fried chips — one that happens to be dairy-free, complete in essential amino acids, and easier on the planet's resources than most animal proteins — cricket protein does the job well.

That's the gap HexaCrunch was built for. Our baked cricket protein rice crackers give you real protein in a snack you'd eat anyway, in three flavours that don't taste like a compromise: Charred Ember BBQ, Crimson Burn Paprika and Siam Blaze Tom Yum. Baked, never fried.

New to it? The Try-All 3-Pack gets you all three flavours for $12. Already convinced? The 5-Pack Mixed is our most-loved combo at $15.

Not suitable for those with shellfish or crustacean allergies.
