Youthfulness Beyond Time

Living long is one thing,
living well is another.

Longevicals assesses every formula with three questions. What is really inside? In what form? Who checks it, and how?

The day we started really reading labels.

Lifespans are getting longer, but the healthy years are not keeping pace. When we started thinking about that gap, our first stop was supplement labels. We saw that big numbers on their own tell you little. So we changed the question. Instead of asking how much, we asked three things: what is it, in which form, and who checks it? Longevicals is built on those three questions. Our approach is pro-longevity: caring about the healthy years.

Omega-3 purity · NUA Series
IFOS 5★re-TG Form

On an omega-3 label, look at two lines.

The label shows the amount of fish oil per capsule and the amount of DHA or EPA on separate lines. Purity tells you how much of that fish oil is omega-3. NuaDHA® and NuaEPA® have over 90% omega-3 purity, in re-TG form. More than 90% of the fish oil in the capsule is omega-3 (mostly DHA in NuaDHA®, mostly EPA in NuaEPA®). Purity, form and dose are read together.

EPA and DHA in separate formulas
NuaDHA® 1000 NuaEPA® 1200

DHA or EPA? We kept them apart.

EPA and DHA are two separate omega-3 fatty acids. Instead of mixing them in one capsule, NUA offers them in separate capsules and in high amounts. If you prefer DHA, take pure DHA. If you prefer EPA, take pure EPA. If you use both, DHA in the morning and EPA in the evening.

25(OH)D
The form measured in a blood test
Uth-FastD™VitamoreD™

Taking vitamin D is one thing, the form you take is another.

The calcidiol monohydrate (calcifediol, 25(OH)D3) in Uth-FastD™ is the form of vitamin D measured as 25(OH)D in a blood test. Vitamin D contributes to the maintenance of normal bones, the maintenance of normal muscle function and the normal function of the immune system.*

Look at independent results, not at us.

NuaDHA® and NuaEPA® are IFOS 5-Star certified. The 90-capsule formats are also covered by NSF Certified for Sport®. IFOS tests every production batch in four test groups: label accuracy, contaminants (PCB, dioxins, furans), oxidation and heavy metals.

Mercury and heavy metals: Every batch is tested for mercury, lead, cadmium and arsenic (the IFOS limit for mercury is 0.1 ppm). Find your batch report

How a supplement becomes Longevicals.

Longevicals assesses every formula with three questions. What is really inside? In what form? Who checks it, and how? Our radical view of quality requires it. A formula enters the portfolio only after five stages, and we ask for evidence at each one. This is not campaign language. It is how we work.

STEP 01

Scientific screening

We review clinical studies in humans, peer-reviewed research and authorised health claims. A nutrient without strong human studies behind it does not enter the portfolio.

STEP 02

Form and quality standard

We work out which form of a nutrient has been studied in most detail in the scientific literature, and which quality criteria to look for: amount of active ingredient, concentration, freshness and contaminant limits. re-TG omega-3 and calcidiol came out of this stage.

STEP 03

A reliable manufacturer

We search worldwide for a manufacturer or brand that meets the standards we set. We do not work with production that falls short of them.

STEP 04

Independent test check

We ask the manufacturer for test results from independent organisations and check them one by one: label amount, oxidation and heavy metals. NuaDHA® and NuaEPA® are tested in the IFOS programme, and their 90-capsule formats are also tested under NSF Certified for Sport®.

STEP 05

Every batch, open results

We make sure every production batch is tested separately and that the results are published for anyone to see. Results for NuaDHA® and NuaEPA® are on the public IFOS results page. With the batch number on your box, you can find the report for your own batch in three steps.

What we say,
and what we choose
not to say.

Longevicals was founded in 2023 and started from a simple question: is living long the same as living well? In our founder's note we explain where that question took us, and which sentences we have chosen never to write. We also set out how we see longevity, through a map of 12 biological processes.

We have purity measured
NuaDHA® and NuaEPA® are IFOS 5-Star certified. Purity and quality are measured in the IFOS programme.
We choose the form and keep EPA and DHA apart
For omega-3, re-TG form and separate EPA/DHA capsules. For vitamin D, calcidiol.
We do not say what we are not allowed to say
We use no health claim for EPA. We write the other claims only in the authorised wording, marked with *.
