Protecting your cells
is an investment in tomorrow.

Oxidative stress silently ages our cells. Understanding this mechanism is already a step towards improving your longevity.

— WHAT YOU NEED TO KNOW

Oxidative stress:
the invisible enemy

Every day, our cells produce energy. This vital process also generates by-products called free radicals — unstable molecules that, in excess, damage DNA, proteins, and cell membranes.

This is known as oxidative stress. A natural phenomenon, but one that can escalate due to daily factors: pollution, unbalanced diet, chronic stress, sun exposure, intense physical exertion.

When it exceeds the body's defensive capabilities, oxidative stress becomes chronic. It is now recognized as one of the central mechanisms of cellular aging and low-grade chronic inflammation.

Oxidative Stress — Concept and Some Practical Implications

This reference review, published in the Annual Review of Biochemistry, establishes oxidative stress as a fundamental imbalance between the production of reactive oxygen species (ROS) and the body's antioxidant capacity. The authors demonstrate that this imbalance is not an epiphenomenon — it is a causal mechanism involved in aging, cardiovascular diseases, metabolic disorders, and neurodegenerative pathologies.

In practice, this means that strengthening your antioxidant defenses is not a trivial act: it is directly intervening in the biological processes that determine how our cells age, and at what rate.

“Our cells don't just age with time. They age under the influence of what they go through.”

— RECOGNIZE THE SIGNS

When your body
sends signals

Oxidative stress is not directly visible. But it leaves traces that we can learn to recognize:

SIGNS OF CHRONIC OXIDATIVE STRESS

Persistent fatigue	Even after a good night's sleep, energy does not return.
Dull or reactive skin	Dull complexion, slower skin recovery, increased sensitivity.
Increased susceptibility	More frequent infections, weakened immune response.
Slow recovery	After exertion or illness, the body struggles to regain its full capacity.
Diffuse inflammation	Sensations of heaviness, sensitive joints, disturbed digestion.

These signals don't mean something is irreversibly wrong. They simply indicate that the balance between free radical production and antioxidant defenses deserves to be strengthened.

SYNERGISTIC ACTIVE INGREDIENTS IN THE BIOLOGYST FORMULA

— THE BIOLOGYST FORMULATION

A solution
designed to last

ANTIOXIDANT DEFENSE is not content with simply providing isolated antioxidants. The formula has been designed to activate several levels of protection simultaneously — targeting both circulating free radicals and endogenous cellular defense mechanisms.

KEY ACTIVE INGREDIENTS · MECHANISMS OF ACTION

Setria® L-Glutathione	Bioavailable patented form of glutathione — the body's primary intracellular antioxidant. Supports liver detoxification and regeneration of other antioxidants.
Alpha-lipoic acid	Universal antioxidant, water and fat-soluble. Regenerates vitamin C, vitamin E, and glutathione, amplifying their action. Protects mitochondria and supports cellular energy production.
Vitamin C (Ester-C®)	Non-acidic, prolonged-absorption form. Neutralizes free radicals in aqueous environments, supports collagen synthesis, and strengthens the immune response.
Vitamin E (mixed tocopherols)	Protection of cell membranes against lipid peroxidation. Works synergistically with vitamin C for complete antioxidant coverage.

"It's not one antioxidant that makes a difference. It's their collective intelligence."

— IS IT FOR YOU?

For those who
think long term

ANTIOXIDANT DEFENSE is for those who understand that health is not managed in an emergency, but maintained daily. It is particularly relevant if you are concerned about:

CONCERNED PROFILES

Chronic stress exposure	Demanding environment, high mental load, urban exposure.
Intense physical activity	Intense physical exertion generates significant amounts of free radicals.
Preventive approach to aging	Act early on cellular mechanisms to preserve your capabilities.
Weakened recovery and immunity	Difficult seasons, convalescence, chronic fatigue.
Skin and connective tissue	Support for collagen synthesis, skin radiance and elasticity.

Recommended dosage

2 capsules daily, preferably in the morning with a meal. Taking it with fats optimizes the absorption of alpha-lipoic acid and vitamin E. A minimum course of 8 weeks is recommended to observe lasting effects.

Precautions

Food supplement not a substitute for a varied and balanced diet. Not recommended for pregnant or breastfeeding women without medical advice. In case of medical treatment, consult your healthcare practitioner.
