Cricket Protein and Vitamin B12: Is Your Snack Really a Source?

Cricket Protein and Vitamin B12: Is Your Snack Really a Source?

Vitamin B12 is one of those nutrients most Singaporeans never think about — until a blood test or a tired afternoon suggests they should. It keeps your nerves and red blood cells healthy, and unlike most vitamins, it’s found almost entirely in animal foods. That’s exactly why cricket protein keeps coming up in conversations about B12. But does a cricket snack actually deliver meaningful B12, or is that just clever marketing? Here’s an honest look at what the research says.

Why B12 matters in the first place

According to the US National Institutes of Health Office of Dietary Supplements, adults need about 2.4 micrograms of vitamin B12 a day. It’s a small number, but a stubborn one: B12 occurs naturally almost only in meat, fish, eggs and dairy, so people who eat little or no animal food can fall short over time. The NIH notes that older adults are especially vulnerable because the body’s ability to absorb B12 from food tends to decline with age, and vegetarians and vegans are flagged as another at-risk group. Left unaddressed, low B12 can lead to fatigue, weakness and, eventually, nerve damage.

So a plant-forward snacker in Singapore has a fair question: are there interesting non-dairy, non-meat ways to nudge B12 intake up? Insects are one of the few options on the table.

What crickets actually contain

On paper, crickets look promising. A 2025 systematic review in Nutrition Research Reviews pulled together 46 studies on the iron, zinc and B12 content of edible insects. Its conclusion was striking: across the board, these micronutrients in edible insects were generally comparable to — or higher than — those in lean beef, pork, poultry and kidney beans. For house crickets (Acheta domesticus) specifically, the review reported freeze-dried cricket at roughly 8.6 to 9.1 micrograms of B12 per 100 grams on a dry-matter basis. The authors went as far as to say entomophagy — eating insects — could potentially help address B12 deficiency.

A broader review of edible crickets in Frontiers in Nutrition reaches a similar headline: crickets are a nutrient-dense food, rich in high-quality protein and a range of vitamins and minerals that vary by species, diet and processing.

The honest caveat: not all “B12” is created equal

Here’s where it pays to read past the headline. A study published in Food Chemistry, “Pseudovitamin B12 and factor S are the predominant corrinoid compounds in edible cricket products,” found that much of what generic lab tests count as “B12” in cricket products is actually pseudovitamin B12 — a closely related compound that the human body cannot use the same way. In their analysis, authentic, bioavailable B12 made up only a small fraction of the total corrinoids measured, with the inactive forms likely produced by bacteria in the crickets’ own gut.

The same systematic review is candid about this too: it flags high variability, inconsistent methods and a lack of insect-specific analytical standards as real limitations. In plain terms, the exact amount of usable B12 you get from any given cricket product is still an open question, and depends heavily on the species, what the crickets were fed, and how the powder was processed.

So what should a Singapore snacker take from this?

A balanced read: cricket protein is a genuinely nutrient-dense ingredient and a promising, sustainable source of protein and minerals — but it’s more honest to treat it as a helpful contributor to your overall diet than as a guaranteed B12 supplement. If you have a diagnosed deficiency, or you follow a strict vegan diet, a snack is not a substitute for a proper supplement or medical advice; speak to a doctor or dietitian and lean on reliably fortified foods.

Where cricket snacks earn their place is in everyday variety. Swapping one refined, empty-calorie snack for a protein-rich, mineral-dense one is a small upgrade that adds up — and it happens to come with an interesting nutritional profile that plain potato chips simply don’t have.

Where HexaCrunch fits in

Our baked brown-rice crackers are made with cricket protein precisely because crickets pack protein and micronutrients into a small, sustainable package. We’d rather be straight with you than oversell: enjoy them as a tastier, more nourishing everyday crunch, not as a B12 pill in disguise. Curious to taste the difference? The Try-All 3-Pack is the easiest way to sample all three flavours and decide for yourself.
