The founder.
Most supplement companies sell confidence. We sell formulations that do what the ingredient list promises — at doses the clinical research actually supports.
Joseph is a Cambridge-trained pharmacologist and the founder of Ultimate Performance Asia, the region's leading premium personal training group. He started Proteus Nutrition because the supplements his UP clients were being sold rarely matched what the clinical research actually supports. Every Proteus formulation is built to a single rule: the dose, form, and ingredient list have to match what works in the trials.

How we formulate.
01
Bioavailability first
Magnesium glycinate not oxide. K2 as MK-7. Curcumin with piperine. Form matters more than dose.
02
Clinical dosing
Doses set by published trial data, not by what fits the marketing claim. Listed on every label.
03
Third-party tested
Every production lot tested for identity, potency, heavy metals, microbial contamination, pesticide residues.
04
Owned facility
Made in our own ISO licensed facility in Singapore. No contract manufacturers, no proprietary blends.
05
Restraint on claims
We don't claim what the science doesn't support. Where evidence is mixed, we say so on the page.
Proteus DLT — Dry Liposome Technology
Most liposomes can't survive the shelf. Ours can.
Shelf Life
Dry-state lattice. No preservatives. No degradation.
Absorption
Reconstitutes as a true liposome on delivery.
Essays from the lab.
-
Why most curcumin you buy doesn't work.
Curcumin's bioavailability problem is well-known in formulation chemistry but almost never honest on supplement labels. Here's what the research actually says.
-
The melatonin dose debate: why more isn't better.
Pharmacy shelf melatonin doses have crept steadily upward. The clinical literature suggests we should be moving the other way.
-
Stress physiology: a pharmacologist's view of the HPA axis.
We've made cortisol the villain of modern life. The reality is more interesting and a lot more useful.
Also from Proteus: the performance range.
Whey protein isolate, dessert protein, and plant-based options. Made in the same facility, to the same manufacturing standards as Labs.
