If you track nothing else, track this.
Heart Rate Variability (HRV) is one of the most powerful and under appreciated indicators of how well your body and brain are adapting to the demands of life.
A high HRV means your nervous system is flexible, your heart is resilient, and your cells are recovering as they should. A low HRV? It’s often the first sign of chronic stress, poor recovery, or accelerated aging.
At MUTO, we believe HRV is the single clearest signal of how well you’re living and how long you’ll thrive. Backed by science and driven by results, here’s why improving your HRV could be the smartest move you make for your health, now and in the decades ahead.

I was very sceptical about the claims made by Muto but decided to give it a go. I have been taking it for a month now and have seen slight raise in HRV . Resting heart rate has dropped from 65 to 55bpm and is consistently 55. Overall I believe this product does work and am gonna give it another month to see what it does. I would defo say give it a go .
HRV reflects how balanced your autonomic nervous system is. When HRV is high, you’re able to shift smoothly between stress and recovery – exactly what your body needs to adapt, repair, and thrive.
MUTO supports this balance through ingredients like curcumin + piperine, which have been shown to reduce cortisol and systemic inflammation, both key HRV suppressors.
Higher HRV isn’t just a sign of reduced stress, it’s associated with lower risk of heart disease, diabetes, and early mortality.
It’s a marker of your biological age, not just your chronological one. MUTO’s inclusion of nicotinamide riboside (NR) supports this longevity signal by boosting NAD+ – a molecule essential for mitochondrial health, energy metabolism, and cellular repair, all crucial for optimal HRV.

HRV drops 15–30% per decade after 20, but higher HRV LINKS to 40% lower risk of heart and brain decline.
Healthy cells (strong mitochondria and low
inflammation) help TO REGAIN YOUR HRV.

Low HRV often reflects poor emotional regulation and higher anxiety. High HRV indicates better adaptability – emotionally and physiologically.
Enter pterostilbene + quercetin, which work together to combat oxidative stress and support cognitive flexibility. Both are neuroprotective polyphenols shown to enhance resilience and mood.

Tracking through my Oura ring for the past two weeks HRV was up significantly after two days. Energy is up and staying consistent. Excited to keep tracking and see what the next few weeks bring.
Your brain and heart are in constant dialogue. When HRV is high, your brain is more alert, your decisions sharper, and your sleep deeper.
MUTO supports this axis with fisetin, a powerful senolytic that clears out dysfunctional cells, linked to improved sleep architecture and neuronal health and vitamin B-complex, vital for neurotransmitter balance and circadian rhythm regulation.


In my private practice, the most common questions I am asked are ‘what is HRV’ and ‘how do I increase it’. We’re all aware of this powerful metric, but many do not truly understand the hacks you can do to increase and/or stabilise. I believe all should pay attention to their habits and their impact on HRV if we want long and healthy lives.

Yes, HRV decreases as we get older. But it’s not fixed. In our MUTO pre-launch beta cohort, we saw a 20% increase in HRV in just 4 weeks, through targeted nutrient support, circadian alignment, and recovery enhancement.
Key drivers? NR for mitochondrial efficiency, grape seed extract for vascular tone and endothelial function, and D3 + K2 for cardiovascular integrity and reduced arterial stiffness, all factors that influence HRV directly.

Within a few days I had more energy, felt more focussed and my Whoop HRV rose from 80 to 120. I’m excited to see the longer term effects of Muto.
HRV helps you know when to push and when to rest, whether you’re training, managing a business, or recovering from illness. It tells you how your system is actually coping.
MUTO’s anti-inflammatory, antioxidant-rich formula, especially grape seed extract + curcumin, helps shorten recovery time, reduce oxidative load, and support parasympathetic dominance (the “rest and digest” mode).
We’re not guessing. Every ingredient in MUTO has a role in elevating your HRV and healthspan:
- Nicotinamide riboside: boosts NAD+, energizes mitochondria, reverses biological ageing
- Pterostilbene: enhances neuroplasticity and antioxidant capacity
- Quercetin + Fisetin: clear senescent cells and lower inflammation
- Grape seed extract: improves blood flow, vessel flexibility, and heart function
- Curcumin + Piperine:modulate cortisol, reduce stress response
- B-Complex: supports energy, mood, and nervous system recovery
- Vitamin D3 + K2: essential for cardiovascular and immune function
Result? Greater adaptability, deeper recovery, sharper cognition, and HRV that tells the story of a longer, more vibrant life.


HRV is the metric of the future, and MUTO is your partner in mastering it.
Because resilience isn’t just for athletes. It’s for everyone who wants to live better, for longer.

Just over a week into Muto and i'm already feeling more energised and have seen an increase in my mood. I've been waiting for the launch of these for a while and after the first week, it's clear it was worth the wait! Excited to see the long term benefits!

I’m a couple weeks into my Muto journey and already feel the benefits. I feel like I have more energy and a clearer mind. Over the past couple weeks I’ve felt more motivated and focused. It’s helping massively towards achieving work and fitness goals.
A great addition to my regime; already seeing a difference very quickly to some of my recovery markers, especially HRV.

I’ve seen immediate improvement in my HRV since using Muto - game changer!

I’ve been using Muto for just over a month now and I’m honestly really impressed. I track all my data with a Whoop band, so I’ve got some solid numbers to back up how I’m feeling.
In the first 4 weeks:
My HRV went up by 32%, my resting heart rate dropped by 7% and my average recovery score improved by 26%
Considering I’ve already got my training, nutrition, and sleep pretty dialled in, seeing these kinds of improvements is actually pretty wild. Muto has definitely given my recovery that extra push and I’ve got considerably more energy throughout the day.
Also, Richie from the team gave me a call just to chat about my background and goals, which was a really nice personal touch you don’t see much these days.
Overall, it’s been a great experience so far and I’m excited to see how things keep progressing.

I started taking Muto a couple weeks ago, and I already feel great. Energy is high, focus is through the roof and I’m waking up full of motivation. Highly recommend!

Feel great

Has definitely helped my sleep and reduced my sugar cravings in the evening massively.

Deffo feel like its changed my daily mood, energy and body

Since taking this supplement I’ve felt brand new. The cellular energy boost it gives you really enables me to power through my day. I take them first thing in the morning every day and can’t live without now.

Started using muto because I felt like my body couldn’t keep up with the amount of exercise I wanted to do. After taking muto, I felt more energised and ready for my next session! Great product!

Tracking through my Oura ring for the past two weeks HRV was up significantly after two days. Energy is up and staying consistent. Excited to keep tracking and see what the next few weeks bring.

I’ve only been taking MUTO a few weeks but can already notice the difference. I predominantly struggle with mornings but already feel myself finding these easier, having more energy throughout the whole day and feeling more focused.

I've been using for one month now and really feel the difference! Better sleep, better skin, more energy - happy days!
