Industry-funded study of the week: a jellyfish supplement!

Jellyfish supplements are a new one to me. Here’s study claiming that they improve cognitive function and memory. If only it were that easy.

The study: Neil E. Wolkodoff, Gerald M. Haase, Joyce A. Curry, (2025), Effects of a Jellyfish Collagen-Based Amino Acid Supplement on Cognitive Function and Memory: A Pilot Investigation, J Clinical Research and Reports, 19(5); DOI:10.31579/2690-1919/532

Purpose: The goal of the current study was to evaluate the effects of oral consumption of an encapsulated powder form of a proprietary jellyfish extract on global cognitive parameters during an eight-week open-label trial in middle-aged and older adults.

Method: The study consisted of supplement consumption twice daily for eight weeks with an at-home, computer-based standard cognitive battery completed at pre-study baseline and at the end of the trial.

Results: EEG total reaction times…decreased by 130 milliseconds and combined trail-making scores demonstrated a reduction of test time by 12 seconds. Both were statistically significant…over half the individuals throughout the study period voluntarily reported positive outcomes, especially related to alertness, energy, focus, and sleep/dream patterns.

Conclusions: This pilot investigation showed that taking a proprietary oral jellyfish collagen supplement may offer meaningful benefits for overall cognitive function and brain activity. The supplement, derived from marine invertebrate collagen, appears to be a promising way to support brain health in healthy middle-aged and older adults.

Comment: This is one of those studies that immediately raises the question: “Who paid for this?”

The funder: The supporting entity, Certified Nutraceuticals, Inc., had no role in study design or execution, data collection or analysis, or manuscript preparation. CN did provide product and testing support for the study.

To this, I say, that’s what they all say. Sometime it’s actually true, but mostly it’s not. Funding influences. And not always in your best interest.
