Ageing is not a clock counting down. It is a biology that answers to how you live, every day, in every cell.

Healthy ageing at Health Royals

Peak Performance is one jar for the systems this article describes: vitamin D3 as Quali-D®, vitamin K2 as MenaQ7®, folate as Quatrefolic®, omega 3 from algae, Hytolive® and Extramel®. Vitamin D contributes to the maintenance of normal muscle function and normal bones, and vitamin K contributes to the maintenance of normal bones.

What happens in the body as we age?

Several processes at once, at different speeds, and most of them respond to how the days are spent.

Biologically, ageing is not one process but several: cells divide more slowly, proteins are turned over more slowly, energy production becomes less efficient, and the immune system changes character. Research on the hallmarks of ageing groups this into a few mechanisms: altered energy metabolism in the mitochondria, oxidative wear, and an immune system drifting toward low-grade activity.

Lifespan is the number of years; healthspan is the number of years with good function and stamina, our subject here. Why we live longer has an article of its own.

Ageing is not one process but several, and most of them respond to what you do with your days.

What do mitochondria actually do?

They convert what you eat and breathe into ATP, the energy every cell runs on.

Nutrients are broken down in steps, electrons pass along a protein chain in the inner mitochondrial membrane, and the energy released builds ATP. The chain is efficient but not perfect: a small share of electrons leaks and forms reactive oxygen species, what we call free radicals.

With age the chain becomes less efficient. Membrane structure changes and enzymes wear, so the same nutrients yield slightly less ATP and slightly more by-products. That is why stamina and recovery feel different at fifty than at twenty-five, and why regularly loaded muscle, which builds new mitochondria, holds its stamina longer.

Several vitamins are coenzymes in those steps. The approved EU wording is precise: thiamine, that is vitamin B1, vitamin B3, folate and vitamin B12 contribute to normal energy-yielding metabolism: not giving energy, but letting the machinery work. It is also why we at Health Royals look at a vitamin's form before its amount: in Peak Performance, folate is Quatrefolic® 5-MTHF and vitamin B12 is MecobalActive® methylcobalamin, at a nutritional level.

Mitochondria are not a detail of ageing. They are where much of it starts.

What is oxidative stress?

An imbalance between the reactive oxygen species a cell produces and the systems that neutralise them.

Reactive oxygen species form naturally during respiration, inflammation, UV exposure and physical load. While the defences keep pace, free radicals serve as signalling molecules. It is when production outpaces defence, year after year, that wear becomes lasting.

Superoxide dismutase, or SOD, is the first enzymatic step, converting superoxide into hydrogen peroxide, which other enzymes then handle. Beyond the enzymes come molecules from food, such as olive polyphenols. Two raw materials in Peak Performance come from this corner of nutrition research: Extramel®, a melon extract naturally rich in SOD, and Hytolive®, an olive fruit extract standardised to hydroxytyrosol, each at the daily amount used in its human studies. More on SOD and oxidative stress and hydroxytyrosol.

Free radicals are normal. It is the imbalance over time that makes the difference.

Why does energy decline with age?

Because stamina is a system response, built where energy production, circulation, sleep and hormonal regulation meet.

Circulation is one link: with age, vessel elasticity and endothelial function can shift, which affects how well tissues are nourished and repaired. Sleep is another: most repair happens overnight, so rhythm counts for more than any single good night.

NAD⁺, involved in energy metabolism and DNA repair, is often raised here, and its decline with age is well documented. Research on whether supplementing its precursors makes a difference for a healthy adult is still young. What we do know is more useful: the vitamins the energy machinery depends on have approved wording, most repair takes place during sleep, and loaded muscle builds more mitochondria.

Stamina is a system response, not a single missing ingredient.

What happens to the brain, muscles and bones?

They age at the pace their energy supply and structure are maintained, and each has nutrients with approved wording.

The brain is among the most energy-demanding organs and therefore sensitive to shifts in cellular energy and blood flow. DHA is a building block of brain membranes, and in approved EU wording DHA contributes to the maintenance of normal brain function at 250 mg per day. Peak Performance provides 300 mg DHA from OMEGATEX® algal oil.

Muscle mass declines from midlife if it is not loaded, while the response to protein slows. Loading and protein intake therefore matter more with age, not less. Vitamin D contributes to the maintenance of normal muscle function.

Bone is rebuilt continuously, and when the balance between breakdown and build-up shifts, often around hormonal transitions, bone density falls gradually. Vitamin D contributes to the maintenance of normal bones, and so does vitamin K, which is why Peak Performance pairs vitamin D3 as Quali-D®, 25 µg, with vitamin K2 as MenaQ7®, 90 µg, the MK-7 form.

Slower collagen turnover in connective tissue shows up as morning stiffness, covered under collagen supplements and skin biology.

Brain, muscle and bone age at the pace their cellular energy and structure are maintained.

What is chronic low-grade inflammation?

A repair system that never fully switches off.

With age the immune system can drift into low, chronic activity that researchers call inflammaging. At the same time, how the body handles glucose, stores fat and responds to insulin changes, and the two tracks are linked: metabolic load drives inflammatory signalling, which in turn worsens metabolic regulation.

The conclusion is practical: the whole system offers more points of contact than one symptom at a time, with steadier glucose responses, less oxidative load and calmer inflammatory pathways. Chromium contributes to the maintenance of normal blood glucose levels, one reason it has a place in Peak Performance. The same pattern appears in scalp biology and in the biology of menopause.

Low-grade inflammation is rarely dramatic in the moment, which is exactly why it is easy to miss over years.

What can you actually influence?

More than the biology above might suggest, and the levers are ordinary ones.

Load your muscles regularly: strength is the clearest signal to muscle and bone to keep their structure. Keep a sleep routine. Spread protein evenly across the day. Move in daily life, not only in training. And watch the nutrients where intake falls short at northern latitudes: Riksmaten shows Swedish intakes most often below reference values for vitamin D, folate and iron, with selenium as a fourth, and long-chain omega 3 is the other gap, as we go through in what Riksmaten shows.

Nutrition is the easiest part of that list to make reliable, and that is where a well chosen supplement belongs: one jar, every day. Format is worth a thought, covered in why we use capsules and not powders. A hormonal transition has its own entry point on menopause and midlife.

What influences ageing most is also the least spectacular: sleep, loading, protein and consistency.

Where does Peak Performance fit in?

As the nutritional base for the systems above, chosen on one principle: fewer jars, more thought. Peak Performance Formula, our daily multivitamin for women with omega 3 from algae, starts from what Swedish intakes lack, and from raw materials with human studies at the amounts those studies used.

The nutrients Riksmaten points to come first: vitamin D3 25 µg as Quali-D®, a deliberate middle level for every day of the year; folate 200 µg as Quatrefolic® 5-MTHF; selenium 27.5 µg; and OMEGATEX® algal oil with 375 mg omega 3, of which 300 mg DHA and 50 mg EPA. Iron is left out, because for women it is a question for a blood test. Vitamin K2 as MenaQ7®, vitamin B12 as MecobalActive®, thiamine, niacin, zinc as L-OptiZinc® and chromium complete the list, all at a nutritional level. For us, the dose is as important as the raw material.

Hytolive® is an olive fruit extract from Alvinesa in Spain, 150 mg standardised to 15 mg hydroxytyrosol, the daily amount used in the randomised, double-blind, placebo-controlled human study on the material, with 450 mg extra virgin olive oil.

Extramel® is a melon extract from Robertet in Grasse, naturally rich in SOD, at 10 mg per daily dose, the amount used in two placebo-controlled human studies on perceived stress, fatigue and sleep-related problems: Milesi and colleagues in Nutrition Journal in 2009, 70 healthy volunteers for four weeks, and Carillon and colleagues in Nutrients in 2014, 61 participants for 84 days. For us, the ingredient cannot be separated from its source, manufacturer and studied dose.

Peak Performance holds twelve named constituents, each with a reason to be there, in an amber glass jar made to stay out on the shelf, with refill pouches by subscription. More on our wellbeing page. We have done the selection so that you do not have to.

Frequently asked questions

Can ageing be slowed down?

Time moves on for everyone. What can be influenced is how well the body's systems work in the years ahead: sleep, loading, diet, recovery and a reliable nutritional base.

Does NAD⁺ help against ageing?

Its levels fall with age, and research on whether supplementing its precursors makes a difference for a healthy adult is still young. What we do know is that thiamine, niacin and vitamin B12 contribute to normal energy-yielding metabolism.

How much DHA does the approved claim apply to?

DHA contributes to the maintenance of normal brain function at 250 mg per day. Peak Performance provides 300 mg DHA from algal oil.
