Training makes exhaust.
Turning oxygen and food into energy makes 'free radicals' as a by-product. The harder you train, the more you make.
You breathe. It makes waste.
Turning oxygen and food into energy makes free radicals as a by-product. It's antioxidants like TetraSOD® that neutralise them before the damage lands.
They took muscle biopsies. The switch was on.
Most supplement evidence stops at how people feel. This one went into the tissue: NRF2 and HMOX1 upregulated, your own SOD, catalase and GPx induced.
Measured in human muscle tissue.
Most supplement evidence stops at how people feel. This trial took muscle biopsies from healthy adults and read the genes: the switch was on, and the enzymes came up with it.
Amateur soccer players, thirty days.
Double-blind, 25 mg of TetraSOD® a day for thirty days. None of these are things an athlete feels on the day. They are things that show up in the block.
Enzyme, not a vitamin
A vitamin neutralises one radical and is spent. Limited support.
An enzyme is catalytic; it keeps clearing, radical after radical.
SOD, catalase and glutathione peroxidase come up with it.
Donors run out. Enzymes do not.
TetraSOD® signals NRF2, the master switch for your own antioxidant and detoxification genes, and SIRT1, which governs mitochondrial upkeep and cellular repair. It works through your genes rather than around them.
9 actives, 4 heroes
Your own defence, switched on.
An enzyme complex — SOD, catalase and glutathione peroxidase — from marine microalgae. Catalytic rather than sacrificial: it keeps clearing, radical after radical.
Fuel at the mitochondria.
CoQ10 is a direct component of the mitochondrial energy chain and the best-evidenced single nutrient in endurance sport. Its weakness is absorption, which is why our liquid form matters.
Zinc does its own work.
Zinc sits inside your own SOD enzymes, so the antioxidant system you already have runs on it.
Selenium builds the enzyme.
Selenium is built into glutathione peroxidase, one of the enzymes that clears peroxides before they reach DNA and membranes.
Nine actives, one tube.
One tube a day, liquid and already dissolved. Golden lemon, ten seconds, no capsules to swallow.
Measured in athletes.
Amateur soccer players, thirty days.
Double-blind, 25 mg of TetraSOD® a day for thirty days. None of these are things an athlete feels on the day. They are things that show up in the block.
What that buys you.
More oxygen delivered per heartbeat, and more haemoglobin carrying it.
Resting heart rate and lactate both came down over thirty days.
Antioxidant enzyme capacity, so the next session starts from a cleaner baseline.
It wins awards.
Best Longevity Ingredient 2026, GHP Global Excellence Awards — awarded to TetraSOD® on published clinical research.
Here's all the data.
Published trials, third-party certification and local registration. Every claim on this page traces back to one of them.
Awarded on published research.
Two registered interventional trials at Loughborough University, plus a randomised trial in men with idiopathic infertility. Human data, at the dose in one tube.
The reviews speak for themselves.
Take after each session. I feel I recover quicker and push myself harder with it.
Used over a 12 week programme. Easy to keep up, and the lemon flavour was good.
Liquid Gold optimises your training and gets results.
