Protein Gummies vs. Shakes: Which Builds Better Habits?

The single biggest predictor of whether protein supplementation works is whether people actually take it consistently. Whey protein is the most studied, most cost-effective supplement in the category. It's also the one people quit first. We wanted to know why — and whether format matters more than people think.

We ran a 90-day adherence test with 24 participants. Half were given whey protein + shaker. Half were given Glÿka protein gummies. Both groups got the same nutrition education and the same daily protein target. No other variables were controlled.

Week 1: Both groups were near 100% adherence. Novelty carried everyone.

Week 4: Shake group adherence dropped to 71%. Gummy group held at 94%. The reasons given were telling — 'forgot my shaker,' 'didn't want to clean it,' 'wasn't near water,' 'felt too heavy after eating.'

Week 8: Shake group at 58%. Gummy group at 89%. The shake group had started treating their daily shake as optional; the gummy group had integrated it into a routine (after lunch, at their desk, post-walk).

Week 12: Final numbers — shake group 52%, gummy group 86%. The gap was not motivation. It was friction.

Cost per gram of protein still favors whey concentrate by a wide margin. If you are highly disciplined and your routine is rock-solid, a shaker is the cheapest path. But the data says most people aren't that disciplined, and the format that removes friction is the format that wins.

This is why we built Glÿka. Not because gummies are magically better for muscle protein synthesis — they aren't. Because they are easier to do consistently, and consistency is the whole game.
