Ask any Indian woman between the ages of 25 and 55 how she feels, and the answer is almost always a variation of the same thing: tired, exhausted, running on empty. And the most common response she receives, from family or even from healthcare providers, is that this is simply the price of being a woman in modern India. It is not.
Persistent, unrelenting fatigue has identifiable, measurable, treatable physiological causes that are often dramatically improvable with the right intervention. The problem is that these causes are chronically under-investigated in Indian women, and the symptoms are normalised for far too long before anyone looks deeper.
This article examines the real science behind why so many Indian women are exhausted, what is happening at the cellular and hormonal level that drains energy, and what evidence-based approaches can genuinely help restore vitality.
Why Fatigue in Women Is Different and Often Missed
Fatigue is one of the most common presenting complaints in general practice worldwide, and women report it at significantly higher rates than men.
Yet it is also one of the most under-investigated complaints, particularly in India, where women’s symptoms are more frequently attributed to stress, overwork, or emotional causes without a thorough physiological workup. Understanding why fatigue in women is distinctive helps clarify why it deserves more serious clinical attention:
- Women have more concurrent physiological demands:
Monthly hormonal cycling, pregnancy, lactation, and the decade-long perimenopause transition each place significant energy and nutritional demands on the body.
A woman simultaneously managing iron depletion from heavy periods, low vitamin D, disrupted sleep from hormonal fluctuations, and high cortisol is experiencing multiple energy-depleting processes at once.
- The investigation threshold is often too high:
Fatigue in women is frequently attributed to stress or lifestyle without systematic testing. Ferritin (iron stores), vitamin D, full thyroid function, B12, and hormonal status are all relevant but not always routinely checked when a woman presents with exhaustion.
- Fatigue is multifactorial in women:
It is rarely caused by a single factor. More commonly, it is the compounded result of two or three simultaneous deficiencies and imbalances that each contribute moderately but, when combined, produce profound energy depletion, which is why single-nutrient corrections sometimes deliver disappointing results.
- The normalisation problem:
Many Indian women have been tired for so long that they have adjusted expectations downward, accepting exhaustion as their baseline rather than recognising it as a departure from how they should feel.
The first and most important shift is recognising that persistent fatigue, the kind that does not resolve with rest, that is present most days, that interferes with concentration and motivation, is a medical symptom deserving investigation, not a life condition to be accepted.
The Most Common Causes of Fatigue in Indian Women
When a woman presents with persistent fatigue, the causes are almost always physiological, and in Indian women, a predictable set of factors comes up again and again. Here are the most clinically significant and most frequently missed contributors to exhaustion in Indian women:
- Iron deficiency and iron deficiency anaemia:
India has among the world’s highest rates of iron deficiency, with women of reproductive age most affected. Monthly menstrual loss, frequent pregnancies, and low dietary iron combine to create chronic depletion.
Critically, iron can be functionally deficient, producing fatigue and cognitive symptoms even when haemoglobin is not yet low enough to meet the clinical anaemia threshold. Checking ferritin reveals the full picture.
- Vitamin D deficiency:
Vitamin D receptors are present throughout the body, including in the mitochondria. Deficiency impairs mitochondrial function, contributes to muscle weakness and aches, and is strongly associated with fatigue and cognitive fog.
With 70 to 90 per cent of urban Indian women deficient, this is one of the most widespread and underaddressed contributors to low energy.
- Thyroid dysfunction:
The thyroid regulates metabolic rate, the speed at which every cell produces energy. Hypothyroidism produces profound fatigue, weight gain, cold intolerance, and brain fog.
It is significantly more common in women than men and disproportionately underdiagnosed in India. A full thyroid panel TSH, free T3, and free T4, is essential for any woman with unexplained exhaustion.
- Vitamin B12 deficiency:
B12 is essential for red blood cell formation and neurological function. Deficiency produces fatigue, weakness, tingling in the extremities, and memory difficulties. It is extremely common in Indian vegetarians and in women on long-term oral contraceptives, which deplete B vitamins.
- NAD+ depletion and mitochondrial decline:
At the cellular level, energy production depends on NAD+, a coenzyme that powers ATP production in mitochondria. NAD+ levels decrease from the mid-30s onwards, and with them, the progressive decline in cellular energy many of us experience: less resilience, slower recovery, and an overall baseline that just seems lower than it was 10 years ago.
- Chronic stress and HPA axis dysregulation:
Chronic HPA axis activation is extremely common in urban Indian women managing careers, families, and societal expectations simultaneously, producing persistent cortisol elevation that disrupts sleep, suppresses reproductive hormones, and depletes cellular energy reserves. The long-term result is a body chronically in a state of energetic deficit.
- Sleep disruption from hormonal changes:
Progesterone has a sedative effect when it falls premenstrually or through perimenopause, and sleep quality deteriorates. Oestrogen fluctuations cause night sweats and hot flushes, disrupting sleep architecture. Poor sleep is both a cause and consequence of hormonal imbalance, creating a compounding cycle.
Most women experiencing severe fatigue have at least two or three of these factors simultaneously active. A comprehensive blood panel, including ferritin, vitamin D, full thyroid function, B12, and hormonal assessment where indicated, is the starting point for identifying what is actually driving the exhaustion.
The Cellular Science of Energy: What Is Actually Happening in Your Body
To understand why fatigue is so pervasive and why targeted interventions can make such a profound difference, it helps to understand what energy production actually looks like at the cellular level and where the system breaks down. Here’s a basic rundown of how your body produces the energy you experience as vitality, and what breaks it:
- ATP is the currency of cellular energy:
Every function your body performs, from making a muscle contract to firing a neuron, runs on adenosine triphosphate (ATP), which mitochondria pump out in real time, using oxygen and nutrients as raw materials. When ATP production is impaired, fatigue results.
- Mitochondria require multiple cofactors:
Efficient mitochondrial function depends on NAD+, iron (for the electron transport chain), B vitamins, and magnesium. A deficiency in any one of these impairs the entire energy production pathway, which is why isolated nutrient deficiencies can produce fatigue even when everything else appears normal.
- NAD+ is the master regulator of mitochondrial energy:
NAD+ sits at the centre of mitochondrial energy production and also activates sirtuin proteins that maintain mitochondrial quality and cellular repair. As NAD+ levels decrease with age, mitochondria become less efficient and produce more cellular waste. This is the molecular basis for the energy drop-off many women feel from their mid-30s onward.
- Oxidative stress damages the energy machinery:
When antioxidant defences become overwhelmed by chronic stress or poor nutrition, free radicals harm mitochondria, further damaging their ability to produce energy in a self-perpetuating cycle.
And that’s why when women focus on just one thing, they often only see partial improvement. It is an interdependent system and requires a multi-factor solution to be fully addressed.
What the Science Says About Restoring Energy in Women
The energizing process in fatigued women is not a peering intervention; it is an orderly examination and treatment of the 3 main contributors to fatigue for every individual. Here’s what the evidence tells us about the most effective approaches:
- Iron repletion for iron deficiency:
As one example, correcting iron deficiency, including sub-anaemic iron depletion diagnosed by ferritin testing, yields unique and reliable improvements in energy, cognitive function, and exercise tolerance. The form matters: we have formulations of iron that are highly bioavailable and better tolerated in the gastrointestinal tract. Surishi’s FERO-XT is formulated to maximise absorption while minimising the digestive discomfort that leads many women to discontinue supplementation prematurely.
- Vitamin D correction:
Multiple clinical trials show that vitamin D supplementation in deficient individuals improves fatigue, mood, muscle function, and overall well-being. Most deficient Indian women require 2,000 to 4,000 IU daily, guided by laboratory monitoring.
- Thyroid treatment:
When hypothyroidism is confirmed on laboratory testing, appropriate thyroid hormone replacement typically produces dramatic and rapid improvement in energy, mood, and cognitive function, but requires correct diagnosis first.
- NMN supplementation for cellular energy restoration:
For women in their 30s and 40s who experience fatigue due to declining NAD+ and mitochondrial efficiency, NMN offers a mechanism-based strategy to restore cellular energy production. MITOV by Surishi Pharmaceuticals delivers NMN at 425mg alongside resveratrol, pterostilbene, and EGCG, addressing cellular energy decline across multiple complementary pathways.
- Sleep optimisation:
Seven to nine hours of consolidated, high-quality sleep is the foundation on which all other energy-restoration strategies depend. Addressing hormonal causes of sleep disruption is often as important as sleep hygiene.
- Stress regulation:
Evidence-based practices, including yoga, pranayama, and moderate aerobic exercise, reduce cortisol, improve HPA axis regulation, and directly support energy metabolism. Studies have shown that practising yoga in Indian women has resulted in measurable improvements in fatigue and quality of life within eight to twelve weeks.
The best protocol for an individual woman is to address her specific identified drivers of fatigue rather than take a one-size-fits-all approach. This is why laboratory investigation comes before supplementation; knowing what is actually depleted determines which interventions will produce the greatest improvement.

Conclusion
The exhaustion that so many Indian women experience is not inevitable, and it is not simply the cost of a busy life.
It is biologically measurable, addressable, and, in most cases, significantly improvable with the right investigation and interventions. Iron, vitamin D, thyroid function, B12, NAD+ levels, hormonal balance, sleep quality, and stress regulation are not abstract concepts.
They are the levers that determine whether a woman moves through her day with genuine energy and clarity, or fights through it on empty.
Surishi Pharmaceuticals is dedicated to giving every Indian woman access to the research-backed, innovative healthcare solutions that her energy and her life deserve. Because a woman who is not exhausted is not just healthier. She is more fully herself.
Frequently Asked Questions
- How do I know if my fatigue is medical or just lifestyle-related?
Fatigue that persists despite adequate sleep, does not improve with rest, and is accompanied by other symptoms, such as brain fog, breathlessness, cold intolerance, and heavy periods, is more likely to have a physiological cause. A basic blood panel, including ferritin, vitamin D, thyroid function, and B12, is the starting point.
- Can NMN supplementation help with fatigue in women in their 30s?
NAD+ levels decline in the mid-30s and contribute to the reduction in cellular energy production that many women notice from that point onward. NMN supplementation restores NAD+ levels and improves mitochondrial efficiency, making it more relevant to age-related energy decline than to deficiency-fueled fatigue.
- Is iron supplementation safe to take without a doctor’s recommendation?
Iron supplementation can have side effects even in the absence of deficiency, and excess iron is toxic. Always confirm iron status through ferritin and haemoglobin testing before starting iron supplements, and use clinically formulated products under appropriate guidance.
- How long does it take to notice improvement in energy after addressing deficiencies?
Iron correction typically produces noticeable improvement within four to eight weeks. Repletion of vitamin D and B12 may take 6–12 weeks to achieve complete effect. Cellular energy improvements from NMN supplementation are typically felt within four to eight weeks of consistent use.
