The Key Takeaways
Corporate women are burning out at work, and most of them stay quiet about it. Discover what sustained stress does to energy, blood sugar and cognition, and which nutrients help women hold up under it.
- 36% of women say work stress is up on last year, and almost 90% think their manager would judge them for saying so (Deloitte, Women @ Work 2025).
- Sustained stress disrupts insulin sensitivity, raises inflammatory markers and impairs sleep, which compounds fatigue and brain fog.
- The Elevator is SISTERLY’s daily multinutrient for women. One sachet, 23 nutrients, targeting burnout recovery, energy, blood sugar, cognition, immunity and hormonal balance.
- Key nutrients that help are CoEnzymeQ10, chromium, methylated B6, folate and B12, plus magnesium, zinc, selenium, vitamin D3 and vitamin K2.
- Nutrition works alongside habit: protein at breakfast, sleep hygiene, and midday movement.
The modern corporate woman is a force to be reckoned with. Leading teams, launching initiatives, balancing work and life at a pace that’s nothing short of relentless. But beneath the polished exterior, many are quietly running on empty. Deloitte’s Women @ Work 2025 study of 7,500 women across 15 countries found 36% saying their stress levels are higher than a year ago, and 25% had taken time off work in the past year because of mental health challenges. Most telling of all, almost 90% believed their manager would think negatively of them if they spoke up about it.
The Science Behind the Slump
Women in corporate roles face a perfect storm of stress, hormonal fluctuations, and disrupted blood sugar rhythms that chip away at physical and cognitive resilience. Many working women experience energy crashes during the workday, and it’s not unusual to struggle with focus and productivity before or during your period.
Stress disrupts insulin sensitivity, increases inflammatory markers, and impairs sleep architecture, and the result is a vicious cycle of burnout. Add irregular meals, caffeine or sugary energy drinks, back-to-back Zooms, and hormone shifts, and it’s no wonder so many women feel stretched to their limit.
Enter: The Elevator
At SISTERLY, we speak to women every day who tell us they’re feeling tired and depleted. When we surveyed our community, the number one health goal wasn’t weight loss or better skin. It was simply: “I want more energy.” That insight directly shaped how we approached the formulation of The Elevator, our daily multinutrient for women. One sachet a day, 23 nutrients, designed to meet the physiological demands of high-performing women.
The Elevator was formulated as a women’s daily foundation for long-term vitality. It supports six key areas where women in business need the most help:
1. Burnout Recovery
When you’re under sustained pressure, your adrenal glands pump out cortisol and adrenaline to keep you boardroom savvy. Meanwhile, your thyroid gland steps up the metabolic pace so you can perform like a boss. However, chronic stress eventually takes its toll on these two power glands, leading to fatigue, weight gain, and brain fog. The Elevator bolsters high-performing women through a synergistic blend of anti-stress nutrients including vitamin B5, C, magnesium and selenium to help replenish the adrenal and thyroid glands.
2. Energy Production
At the heart of cellular energy is Coenzyme Q10, included at a generous 150 mg (Ubiquinone) dose. CoQ10 fuels mitochondrial ATP production and also helps neutralise oxidative stress, both essential for sustained energy output, particularly in women over 40 whose natural CoQ10 levels may decline with age (Littarru & Tiano, 2010).
3. Blood Sugar Balance
Chromium picolinate is included at 40 mcg per sachet, the clinically supported form studied to support insulin sensitivity and help regulate blood glucose levels. This supports more even energy and mood throughout the workday and helps you sidestep those 3pm patisserie cravings.
4. Cognitive Function
Cognitive clarity and mental stamina rely on the smooth synthesis of neurotransmitters like dopamine. Vitamins B6, folate and B12, play pivotal roles in this pathway. The Elevator includes the highly absorbable, methylated and active forms of these three B-vitamins for optimal bioavailability.
5. Immune Resilience
Commuting, working in busy offices and shared spaces often coincides with immune challenges. Zinc, selenium, and vitamin D3 are all immune-critical nutrients, with widespread insufficiencies documented in Ireland (TILDA, Trinity College Dublin). Supplementing with these nutrients helps to build immune resilience during times of high workload and travel.
6. Hormonal Balance
Magnesium, zinc, and vitamin B6 work in tandem to support hormone production and regulation. Magnesium, in particular, helps in managing PMS symptoms and premenstrual or perimenopausal anxiety and insomnia. Meanwhile, vitamin K2 plays a lesser known but vitally important role in calcium metabolism and bone health, particularly relevant for postmenopausal women.
Beyond The Elevator: Smart Lifestyle Swaps
Pairing The Elevator with small, sustainable lifestyle changes can yield exponential results:
- Eat a protein-rich breakfast to stabilise blood sugar and cortisol.
- Prioritise sleep hygiene: block blue light after 9pm and reduce evening alcohol intake.
- Use movement strategically: short midday walks, or yoga breaks help regulate cortisol and boost cognitive performance.
- Cycle sync your workflow: schedule creative or high-stakes tasks in the follicular or ovulatory phases when mental clarity peaks.
The Bottom Line
The pace of modern work isn’t slowing down, and neither are we. When women in business are supported with the right nutritional tools and a smarter approach to daily health, the results are powerful: sharper thinking, balanced moods, stronger immunity, and a return to sustained energy and positive mindset. Women shouldn’t have to choose between ambition and wellbeing, we deserve both.
