Your Next Trial Doesn’t Have to Take Three Years
6 to 9 months from first call to published data, stage by stage. What happens in each window. What speeds it up. What causes delays, and how to avoid them.
With the right study design and the right partner, most nutrition and supplement brands can go from first call to published data in 6 to 9 months. Gold-standard design. Randomised, double-blind, placebo-controlled. Published, peer-reviewed, defensible.
Now I will break the timeline down stage by stage in detail.
I’ll walk you through:
The 6 to 9 month timeline
What causes delays, and how to avoid them
Why the university version takes 18 to 36 months
Does a published paper behind your brand before Christmas sound interesting?
If someone on your team handles your R&D plan or your marketing calendar, send it to them. This article could change how they sequence the next 12 months.
1. The Seven-Stage Timeline
Seven stages, 6 to 9 months. Here’s what happens in each.
Stage 1 (Weeks 1–2): From first call to a scope you can approve
Every trial begins with a discovery call.
Your product. The outcome you want evidence for. The market you’re selling into. The timeline you have to hit. Downstream, that call shapes everything.
From that conversation, a good commercial partner designs three study options at different investment levels. Different outcome combinations, different sample sizes, different depth of evidence.
Within a week of our first call, we can schedule a follow-up call to discuss the project, the data you would get on your product, and how long it would take us to collect it.
Key Point: Even if you’re not sure where to start, this shouldn’t stop you
At StudySetGo, we’re a team of nutritional scientists who understand how your products work and what is most likely to be some effects that can be measured in these kinds of trials.
Don’t let your uncertainty stop your brand from getting evidence; let us help you.
Stage 2 (Weeks 2–4): Discussing the protocol worth publishing
Once we understand what product we’re looking at and the type of evidence you want to associate with your brand, the team begins designing the protocol.
A protocol is the document that defines
The research question
Participant inclusion and exclusion criteria
Outcome measures
The data collection schedule
This document is the foundation of every credible study. Every decision you make inside it either strengthens or weakens your evidence.
Key Point 1: Most timeline delays trace back to weak protocol design.
Time spent here buys speed everywhere else.
Key Point 2: Any change to the protocol after ethics approval requires a resubmission, which takes weeks. Get clear on the claim you want to prove before drafting the protocol.
Stage 3 (Weeks 4–7): Independent ethics approval
Once payment has been processed, the protocol goes to an independent Research Ethics Committee for review.
We handle all of these components for you, so you don’t need to worry about it!
Ethics approval is a legal requirement before any participant recruitment can begin. No exceptions.
This is where most university-run trials lose two to six months.
University ethics committees typically operate on monthly review cycles. A submission that arrives the week after the monthly meeting is deferred to the next cycle. Two months can go by before the review even begins. If the committee requests amendments, another cycle.
In contrast, Independent Research Ethics Committees review on a rolling basis. Approval typically lands in three to five weeks.
The benchmark to hold your partner to:
If a trial partner is directing you through a university committee without a very specific scientific reason, ask why. The default for a commercial trial should be an independent board.
Stage 4 (Weeks 7–10): Recruitment
Once ethics is approved, recruitment begins.
This is the single biggest risk to your timeline and the stage at which a good partner earns their keep.
As a PhD researcher, this used to be the bane of my existence; now this is something that is no longer a factor with our recruitment engine.
A managed trial makes this a massive priority because, for you, your timelines are paramount. The advert has been drafted. Once we get the green light from ethics, hundreds of people will see adverts relating to your trial.
Recruitment speed depends on how narrow your criteria are:
Broad criteria (healthy adults aged 25 to 55) recruit in two to three weeks
Moderately narrow criteria (adults with self-reported sleep issues) recruit in three to four weeks
Narrow criteria (post-menopausal women with borderline hypertension) recruit in six to ten weeks, sometimes longer
Key point: The inclusion criteria you set are as much a timeline decision as a scientific one.
Every added criterion narrows your recruitable population. Before you lock the protocol, ask your partner to model recruitment against their existing panel. You want the answer before ethics, not after.
Stage 5 (Weeks 10–22): Data collection running in parallel
Data collection runs for the length of your intervention. Most nutrition and supplement studies run 8 to 12 weeks. Some run 16 to 24 weeks for body composition or longer-term metabolic endpoints.
This is the stage where remote-first design collapses a bottleneck that once defined every lab trial.
A traditional trial runs participants through one site, one at a time.
60 participants times one coordinator times one baseline visit each equals weeks of onboarding before the intervention even begins. Then weeks more at the end for follow-up.
A remote-first trial allows for many more participants to be in a study at any given time.
Everyone onboards from home, asynchronously, from anywhere in the country. The queue is removed. The 12-week intervention takes 12 weeks plus a few weeks at either end, rather than 12 weeks plus many months of sequential site visits.
At-home blood kits, validated wearables, Bluetooth body composition scales, and digital questionnaires deliver the objective data.
Why does this matter? Speed is key
The same trial, done over three years vs just one with a remote design, has massive implications for your company that are hard to underestimate.
Stage 6 (Weeks 22–27): A submission-ready manuscript
Once data collection closes, the statistician runs the pre-specified analysis.
The scientific writing team prepares the manuscript. Data cleaning, statistical modelling, interpretation of results, and a submission-ready paper for a peer-reviewed journal.
This isn’t just a PDF; this is your ticket to be able to go to conferences and shout about how scientifically aligned you are and further bolster your credibility to highlight how you’re different from other brands.
Four to six weeks.
The piece most founders underestimate: a manuscript prepared by a team that has written dozens of them moves dramatically faster than one written from scratch.
Stage 7 (Week 27 onwards): Evidence you can use from manuscript acceptance
Peer review and publication timelines vary by journal.
You do not need to wait for the physical issue to go live.
From the moment the journal formally accepts the manuscript, you can use the evidence in marketing. Most advertising platforms and retail buyers accept an acceptance letter as substantiation. Your marketing calendar can begin.
2. What breaks this timeline
The seven stages above assume a well-run, managed trial. Here are two things that most commonly break the timeline:
a. Recruitment shortfall
Slow recruitment is the single biggest cause of trial delays.
The most common drivers:
Overly narrow inclusion criteria
Underestimating how long screening takes
Being limited to certain geographies (Not an issue with remote trials)
The fix is structural.
b. Ethics through a university committee
University ethics committees were not designed to operate at a commercial pace.
For a brand with a launch date already set, the university ethics route alone can add months to the 18-month default. Independent ethics boards exist specifically to remove this bottleneck.
3. Why does the university path take 18 to 36 months
A university-partnered trial typically involves:
A commercial contracts team processing your agreement: 3 to 12 months is common
Ethics submission to a university committee: 2 to 6 months
Recruitment limited to a certain city (Small pool of people)
Data collection paced around academic terms and researchers’ availability
The total rarely comes in under 18 months.
None of this is a failure of the researchers themselves.
The academic system was built for long-term scientific programmes where an 18-month delay to a paper is acceptable. For a brand with a product launch, it usually is not.
If you’re at a decision point…
If you have a product launch in the next 12 months, recruitment is where the timeline most commonly slips. Build the conversation with your partner around recruitment before anything else.
If a university quote has already landed in your inbox, compare its contracts and ethics line against the 6 to 9-month benchmark above. That comparison usually tells you which path fits.
If you’re scoping research budget for your next financial year, work backwards from 6 to 9 months from the first call to usable evidence. The 12-month content plan sits on top of that.
The Bottom Line
Three years is the wrong number. With the right partner and the right design, 6 to 9 months from first call to usable evidence is the ceiling for most supplement and nutrition products.
With a 6- to 9-month route, you'll have peer-reviewed evidence on your label while your competitors are still waiting for ethics approval.
