THREE International is a direct-selling wellness supplement company founded in 2023 by CEO Daniel Picou and led scientifically by Dr. Dan Gubler, a Caltech-trained phytonutrient chemist. Its distinguishing feature is a formulation strategy built around bioavailability — using cellular absorption technology, including liposomal delivery, to improve how much of each nutrient reaches the body. It is a legitimate company with real science and third-party testing; like any network-marketing business, its model and marketing claims warrant scrutiny, which this review provides.
Is THREE International Legit?
This is the question most people arrive with, so I will answer it directly. Yes — THREE International is a real company with verifiable substance behind it, not a fly-by-night label. The evidence for that is concrete: a named and credentialed scientific leader, published third-party testing, and inclusion of one of its products in the Prescribers Digital Reference, a standardized reference healthcare professionals use to review formulations. Those are not things a hollow brand typically has.
That said, "legitimate" and "right for you" are different questions. THREE uses a direct-selling model, its absorption figures include in-house laboratory data alongside independent science, and — as I disclose on every page — I am compensated as a Founding Member. A fair review has to hold all of those facts at once, which is what the rest of this page does.
The Company: Who Is Behind THREE?
THREE International (also styled III International) launched in the spring of 2023. Its founder and CEO is Daniel Picou, an industry veteran who built the company around what it calls three pillars — people, purpose, and platform. The scientific direction comes from Chief Scientific Officer Dr. Dan Gubler, a Caltech-trained phytonutrient chemist and former professor whose background is central to the brand's credibility.
- Founded: Spring 2023, Lehi, Utah.
- CEO / Founder: Daniel Picou.
- Chief Scientific Officer: Dr. Dan Gubler, Ph.D. — Caltech-trained, with a reported 16+ patents and 70+ prior supplement formulations.
- Scientific Advisory Board: a panel of physicians and clinicians backing formulation decisions.
- Model: direct selling / network marketing, with independent members.
- Notable validation: its GLP THREE product was added to the Prescribers Digital Reference in 2026.
What Is THREE's Cellular Absorption Technology?
Cellular Absorption Technology is THREE's name for its formulation approach aimed at improving bioavailability — how much of each nutrient survives digestion and reaches the bloodstream and cells. It includes liposome encapsulation among a reported eleven delivery methods, and the company publishes in-house Caco-2 cell absorption figures for its formulas.
The premise is sound and independently supported: for many nutrients, delivery format genuinely changes how much reaches you. I cover the full science — including the peer-reviewed human evidence for liposomal delivery, and its limits — in the complete cellular absorption guide. The short version is that liposomal and micelle-based delivery has the strongest support for poorly-absorbed compounds like vitamin C, CoQ10, glutathione, curcumin, and resveratrol — which happen to be exactly the kinds of compounds THREE uses these methods for. Mechanistically, that is a reasonable match.
The THREE Product Line
THREE's catalog is organized around specific wellness goals, each formula built on the same absorption-first philosophy. Here is the line, with links to the full independent review of each.
Vitalité

Metabolic support built on MBC-267 salmon-derived peptides; PDR-listed. A dietary supplement, not a medication.
Read the GLP THREE review →The Science: How Strong Is It?
THREE publishes three kinds of evidence, and they are not equal in weight. Being clear about the difference is the single most useful thing an independent reviewer can do.
| Evidence type | What it is | How much weight it carries |
|---|---|---|
| Caco-2 absorption assays | In-vitro cell-culture tests of how well a formula crosses an intestinal cell layer. | Useful formulation evidence; not a human result. |
| Epigenetic / gene-expression data | In-vitro measurements of how ingredients affect gene expression in cell lines. | Mechanistically interesting; directional, not clinical proof. |
| Independent ingredient research | Peer-reviewed studies on the individual compounds THREE uses. | The strongest leg — but it concerns the ingredients, not necessarily THREE's specific finished products. |
| PDR listing | Inclusion of GLP THREE in the Prescribers Digital Reference. | A credibility and transparency signal; not an efficacy endorsement. |
My honest read: THREE's science is genuinely above average for a direct-selling supplement company, and its central claim about bioavailability rests on solid independent ground. The gap — the same gap that exists across almost the entire supplement industry — is between in-vitro data and human clinical outcomes. THREE has more of the former than most competitors and, like most competitors, limited amounts of the latter.
New to this kind of evidence? Two plain-language explainers: what a Caco-2 absorption study is, and what “9.5X absorption” actually means.
THREE International: Pros and Cons
Strengths
- A credentialed, named scientific leader in Dr. Dan Gubler.
- Bioavailability-first philosophy that independent science supports.
- Liposomal delivery applied to the right compounds (curcumin, resveratrol, glutathione, vitamin C).
- Third-party testing and a PDR listing for transparency.
- Clean labels — the company states it avoids fillers, binders, and excipients.
Limitations & cautions
- Absorption figures are largely in-house Caco-2 data, not human trials.
- Direct-selling model means marketing enthusiasm can outrun evidence.
- Premium pricing versus mass-market supplements.
- Supplements are not evaluated by the FDA and are not medications.
- Reviewer (me) is a compensated Founding Member — weigh accordingly.
Who Is THREE For — and Who Should Be Cautious?
Based on the evidence, THREE makes the most sense for someone who already believes delivery format matters, wants clean-label formulas targeting poorly-absorbed nutrients, and is comfortable paying a premium for that. It makes less sense for someone who needs simple, well-absorbed nutrients that a standard multivitamin delivers fine, or who is uncomfortable with a direct-selling model. And anyone with a medical condition, or taking medication, should talk with a physician before adding supplements — particularly the metabolic-support product, which is a supplement and not a substitute for prescribed treatment.
Frequently Asked Questions
How THREE Products Compare to the Alternatives
A fair way to judge any THREE product is against the mainstream option it competes with. These head-to-head comparisons lay out the honest differences — where THREE's approach adds something, and where a cheaper or standard alternative does the job:
- Vitalité vs. a standard multivitamin — breadth and delivery vs. simple, low-cost gap-filling.
- Liquid marine collagen vs. collagen powder — what actually drives absorption (it isn't liquid vs. powder).
- Kynetik vs. standard energy drinks — what really causes the crash, and the L-theanine difference.
- GLP THREE vs. prescription GLP-1 medications — a careful account of two genuinely different categories.
The Verdict
THREE International is one of the more scientifically serious companies in the direct-selling supplement space. Its bioavailability-first thesis is well-founded, its scientific leadership is real, and its use of delivery technology is aimed at the right compounds. The honest limitation — shared with nearly the entire industry — is the distance between cell-culture data and human clinical outcomes, and the pricing and marketing dynamics that come with a network-marketing model. If you understand those trade-offs, THREE is a credible choice. If you want the full science that underpins the whole approach, read the cellular absorption guide next.
