Buy Noestres®

Because sustained stress isn't just a feeling: it's a physiological process that activates the HPA axis (hypothalamus-pituitary-adrenal), chronically elevates cortisol, depletes wellbeing neurotransmitters and generates accumulated oxidative damage in cells. Classic relaxants like valerian or passionflower act on the immediate symptom — agitation — but don't touch any of those three causes. The result is that the person takes them, calms down for a moment, and the stress remains exactly where it was.

What we don't do is use "chronic stress" as an empty marketing hook, because COEUS's commitment is the opposite: that every ingredient you read has behind it a formula, a meaningful dose and a synergy with the rest. Living without chronic stress isn't a slogan. It's the goal. And Noestrés® is the nutritional architecture we work on every day to bring you closer to it.

Because classic relaxants do only one thing: sedate with valerian or passionflower, provide B vitamins for tiredness, or include a single adaptogen. NOESTRÉS® works on the three origins of chronic stress simultaneously. Ashwagandha KSM-66® and rhodiola modulate the hormonal stress axis. L-theanine, magnesium bisglycinate and active B vitamins sustain neurochemical balance without causing drowsiness. And resveratrol, ALA and ferulic acid protect cells from accumulated oxidative damage. It's not more of the same: it's a radically different mechanism of action for a problem that conventional relaxants don't solve.

Noestrés® is formulated precisely for that profile. L-theanine, at 200 mg per dose, promotes alpha brain waves that generate a state of calm alertness — calm without sedation. Ashwagandha KSM-66® regulates the cortisol response without acting as a nervous system depressant. The result is that you can manage the day's pressure with more calm and the same mental clarity, without the sedative effect that makes many people abandon classic anti-stress products.

If the stress has lasted more than 2-3 weeks and is accompanied by muscle tension, irritability, mental fatigue or non-restorative sleep, the body is already in a state of sustained activation that habit changes alone take a long time to reverse. NOESTRÉS® doesn't replace rest, exercise or time management: it makes them more effective because the nervous system has the resources to respond. The person who notices they "do everything right but still feel the same" is exactly who it's designed for. If the stress is occasional and mild, habits may be enough. If it's sustained and affects daily performance, NOESTRÉS® makes the difference.

NOESTRÉS® works in three layers:

Stress axis regulation — Ashwagandha KSM-66® + Rhodiola rosea. KSM-66® is the registered form of ashwagandha with the strongest clinical evidence: controlled human studies show reductions in cortisol, perceived stress and anxiety. Rhodiola rosea increases the body's load-bearing capacity against sustained stress and reduces mental fatigue. Together, they buffer the stress response and increase resilience for future episodes.

Neurochemical balance — L-Theanine + Magnesium Bisglycinate + B6 (P-5-P) + B12 (Methylcobalamin). L-theanine (200 mg) promotes alpha waves and relaxed alertness without sedation. Magnesium bisglycinate provides neuromuscular relaxation and serves as a cofactor for hundreds of reactions. Vitamin B6 in P-5-P form and methylated B12 in active forms requiring no conversion — essential for the synthesis of serotonin, dopamine and GABA.

Cellular protection — Resveratrol 98% + Alpha Lipoic Acid + Ferulic Acid + Bioperine®. Chronic stress generates inflammation and accumulated oxidative damage. Resveratrol activates SIRT1 for cellular repair. ALA recycles antioxidants like glutathione and activates AMPK. Ferulic acid stabilises resveratrol, improving its activity. Bioperine® improves the bioavailability of the entire formula.

NOESTRÉS® has a progressive and cumulative effect profile. In the first days, greater mental calm without drowsiness is noticed. Between the second and third week, energy and resistance to sustained stress improve. After one month of regular use, the effect is complete: lower stress response, more clarity and better quality of night-time rest. Explaining this progression is key to adherence: anyone expecting an immediate effect like an anxiolytic will give up before noticing the real results.

Generally yes, but with important nuances. Ashwagandha and rhodiola may interact with thyroid medication, immunosuppressants and sedatives. If you take anxiolytic or antidepressant medication, you should consult your doctor before adding NOESTRÉS®. Alpha lipoic acid requires caution in people with thiamine deficiency or undergoing chemotherapy. Not suitable for pregnancy, breastfeeding or minors. For profiles without concomitant medication, the safety profile is solid.

No. It's one of the most important differentiators of NOESTRÉS® compared to classic anti-stress products. L-theanine promotes relaxed alertness, not sedation. Ashwagandha and rhodiola increase stress adaptation capacity without depressing the nervous system. It can be taken in the morning while maintaining full cognitive performance throughout the day. For profiles with difficulty sleeping, some prefer to take the dose in the afternoon-evening to benefit from the neuromuscular relaxation effect of magnesium.

The retail price is €37.90 per bottle (30 days at the recommended dose), which works out to €1.26 per day. With a monthly subscription you get a permanent 15% discount: €32.22/month, that's €1.07 per day. Single-adaptogen formulas such as ashwagandha alone or rhodiola alone range from €15-25 without the three fronts of action or active forms. NOESTRÉS® provides registered KSM-66®, three simultaneous layers of action, B vitamins in active forms and cellular protection. It's the lowest price in the COEUS catalogue for one of the most frequent and recurring problems.

For adults with sustained stress lasting more than a month, mental fatigue associated with work stress, students and exam candidates in high-pressure phases, and people who have tried relaxants and abandoned them due to the sedative effect. It's not the first choice for severe primary insomnia or intense acute anxiety requiring medical intervention. Within the COEUS catalogue, it combines especially well with RETROMAG® as a mineral support base, with RENERGY® for the profile with predominant cognitive fatigue, and with RESCANSO® if night-time rest is compromised. Vegan, gluten-free, lactose-free and no added sugars.

Pack Zen combines NOESTRÉS®, Rescanso® and Retromag® for those whose main issue is chronic stress and its effects on sleep and the nervous system. It's the most focused pack for calm, emotional recovery and deep rest. Ideal during periods of mild-to-moderate anxiety, mental exhaustion or stress-related insomnia.

NOESTRÉS® works during the day modulating the cortisol axis without causing drowsiness. Rescanso® and Retromag® work at night to support deep sleep and muscle relaxation. Cortisol regulates in a sustained way from weeks 4-8. Protocol: NOESTRÉS® with breakfast; Retromag® and Rescanso® 30-45 minutes before sleep.

2 capsules a day, ideally split: 1 with breakfast and 1 with lunch. The distributed intake maintains stable adaptogen levels during the hours of greatest mental load. With food because it improves digestive tolerance. Every day, because the effect on stress response is cumulative and consolidates at 2-4 weeks. Vegan, gluten-free, lactose-free and with no added sugars.
