Chronic fatigue is one of India's most underdiagnosed conditions. Millions of Indians walk around perpetually exhausted, attributing it to stress or ageing when the real culprit is often treatable: iron deficiency, B12 deficiency, vitamin D insufficiency, sleep deprivation, or thyroid dysfunction. Energy is not something that supplements alone can fix — but addressing the nutritional deficiencies that cause fatigue makes an enormous difference.
This guide identifies the root causes of chronic fatigue specific to Indians and provides actionable solutions.
Chronic fatigue in 80% of Indian cases is due to: iron deficiency anaemia, B12 deficiency, vitamin D insufficiency, poor sleep quality, or thyroid dysfunction. All are testable and treatable. Addressing the root cause removes fatigue entirely — not temporarily like stimulants.
Testing for Fatigue Causes
Before supplementing blindly, get tested: Complete Blood Count (CBC) — for anaemia; Serum ferritin — for iron; Serum B12 and folate — for B-vitamin deficiency; Vitamin D 25(OH)D — for deficiency; TSH and free T4 — for thyroid dysfunction; Sleep study if sleep quality is suspected.
Addressing Root Causes
For iron deficiency: 100–200mg elemental iron daily for 3 months (see iron deficiency article). For B12 deficiency: 1,000–2,000mcg daily or monthly injections (see B12 article). For vitamin D: 2,000–4,000 IU daily depending on baseline (see vitamin D article). For poor sleep: see sleep supplements article. For thyroid: work with endocrinologist to optimize levothyroxine dosing.
