Defense in three sips
No routine to learn, no pills to swallow. One bright golden tube a day.
One 12g Golden Lemon liquid tube daily — stir into 300ml water. No pills, no chalky powder, no fishy taste.
Patented TetraSOD® delivers a surge of superoxide dismutase — the fastest, first-line antioxidant enzyme your body has.
Oxidative stress drops, inflammation calms and your own defenses ramp up — protecting every cell as you age.
Who it’s for
If any of these sound like you, your cells are taking more free-radical hits than they can clear.
You want to age slowly and protect your cells, DNA and mitochondria for the long run.
Cellular agingLong hours, poor sleep and pressure quietly raise the oxidative load on every cell.
Less oxidative stressIntense exercise floods the body with free radicals — great for fitness, tough on recovery.
Faster recoveryPollution, screens, sun and processed food add up to constant daily free-radical exposure.
Daily defenseLow energy and sluggish, foggy days that hint your cellular engines need protecting.
More energyYou want skin that looks brighter and firmer — protected from the inside, not just on top.

Meet TetraSOD® — the antioxidant that never runs out
A vitamin neutralises one free radical, then it’s spent. TetraSOD® is an enzyme — superoxide dismutase, the only antioxidant that disarms radicals catalytically, again and again.
harmless
Stress, exercise, pollution, sun and aging generate superoxide radicals constantly — silently damaging cells, DNA and skin.
Derived from the marine microalga Tetraselmis chuii, it’s the richest natural source of SOD — your body’s first responder.
As an enzyme, SOD disarms superoxide into harmless oxygen and water — over and over, without being used up.
It also switches on your own catalase, glutathione and NRF2 — a whole-body antioxidant cascade that keeps working.
Not one antioxidant — a whole cascade
TetraSOD® carries the three master antioxidant enzymes plus the algae’s marine fats and pigments — each clearing a different link in the damage chain.
The fastest antioxidant in the body — it instantly converts superoxide radicals into harmless oxygen, catalytically and continuously.
Takes over from SOD and breaks down hydrogen peroxide into water and oxygen, clearing the next link in the damage chain.
Clears lipid peroxides and recycles glutathione — repairing cell membranes and keeping your master antioxidant topped up.
The algae’s natural marine fats and golden pigments shield cell membranes and support visibly healthier, brighter skin.
One tube, four systems
Where the SOD goes and what it protects. Tap through cells, defense, energy and recovery.
A self-renewing antioxidant shield
Unlike a vitamin that’s spent after one radical, SOD works catalytically and switches on your own catalase and glutathione — so your defenses rebuild themselves.
One enzyme, three frontiers
The same cellular defense shows up in clinical trials across performance, fertility and healthy aging.
In amateur footballers, daily TetraSOD® improved aerobic capacity and oxygen delivery — easing the cardiovascular strain of every session.
In men with idiopathic infertility, TetraSOD® raised semen quality and cut oxidative DNA damage over one full spermatogenic cycle.
By switching on NRF2 and SIRT1 and protecting mitochondria and DNA, TetraSOD® targets the cellular drivers of how fast you age.
*From published and registered clinical trials on TetraSOD® / SOD-rich Tetraselmis chuii — amateur athletes (25 mg/day, 30 days) and idiopathic male infertility (250 mg/day, 90 days). Longevity effects reflect NRF2/SIRT1 pathway activation reported in preclinical research. Individual results may vary.
The numbers behind cellular defense
Outcomes reported in research on SOD-rich Tetraselmis chuii (TetraSOD®) and its antioxidant enzyme activity.
Increase in internal antioxidant-enzyme activity (SOD, catalase, GPx) reported with SOD-rich T. chuii.
Reduction in oxidative-stress markers as free radicals are neutralised at the source.
Down-regulation of pro-inflammatory factors and a calmer inflammatory balance.
Improvement in markers linked to mitochondrial function and ATP synthesis.
*Based on published research on SOD-rich Tetraselmis chuii (TetraSOD®) and its capacity to raise endogenous antioxidant-enzyme activity and lower oxidative stress, alongside reported experiences from BioActive+ users. Individual results may vary.
Every tube, fully loaded
Marine SOD plus the vitamins and minerals that act as its cofactors — so the whole antioxidant cascade can work.
Full formula
TetraSOD® (SOD-rich Tetraselmis chuii microalgae) — naturally providing Superoxide Dismutase (SOD), Catalase and Glutathione Peroxidase, marine omega-3 DHA and golden carotenoids — with Vitamin C, Zinc and Selenium as antioxidant cofactors, natural lemon flavour and trace mineral water.

Brighter days, real reviews
I train 5 days a week and the day-after soreness has dropped massively. The Golden Lemon shot is now the first thing I do every morning.
A month in and people keep asking what I changed. My skin looks brighter and calmer — it really does feel like protection from the inside.
I’m in my 50s and wanted something for the long game. Energy is steadier, afternoons aren’t a write-off, and I love that it’s natural marine algae.
Questions, answered.
TetraSOD® is a patented marine ingredient grown from the microalga Tetraselmis chuii — the richest natural source of superoxide dismutase (SOD). SOD is your body’s “master antioxidant”: the very first enzyme that neutralises superoxide before it can damage your cells, DNA and skin.
A vitamin antioxidant neutralises one free radical and is then used up. SOD is an enzyme — it works catalytically, disarming radical after radical without being spent. TetraSOD® also switches on your own SOD, catalase and glutathione.
Many people feel steadier energy and quicker recovery within 7–14 days. The deeper cellular benefits build over the following weeks of daily use.
Yes. TetraSOD® is 100% vegan, derived from marine microalgae, and Tetraselmis chuii is approved in the EU as a Novel Food. It’s non-stimulant and designed for daily use.
One 12g Golden Lemon liquid tube daily, any time of day. Stir into about 250ml of water — no pills and no fishy algae taste.
Patented TetraSOD® with SOD, catalase and glutathione peroxidase, plus vitamin C, zinc and selenium, and the algae’s natural omega-3 DHA and golden carotenoids. Free from common allergens.
