Supplements for caregivers

The caregiver stack — rationale by ingredient

Vitamin D3 1,000–2,000 IU/day

Caregivers spend more time indoors than the general population; deficiency rates are accordingly higher. Mood and immune-function benefits are foundational. Test 25-OH-D if possible.

Magnesium glycinate 300–400 mg in the evening

Magnesium intake is below recommended in most adults; chronic stress depletes magnesium status further. The glycinate form is well-tolerated, supports sleep, and reduces subjective tension. It is the unglamorous backbone of a stress stack.

Omega-3 (EPA-predominant) 1,000 mg EPA/day for adjunctive mood support

The meta-analytic evidence for EPA-predominant omega-3 in depression is consistent. Caregiver depression rates are roughly 2–3× the general population; omega-3 is reasonable adjunctive to therapy and lifestyle changes. Not a substitute for professional mental-health care if depression is significant.

L-Theanine 200 mg during high-acute-stress moments

Acute stress (the hospital admission, the difficult care interaction) responds to 200–400 mg L-theanine taken 30–60 minutes before the stressor. Reduces cortisol response without sedation. Particularly useful for caregivers who don't want benzodiazepines but need acute support.

Low-dose melatonin 0.3–0.5 mg for sleep-onset insomnia from fragmented schedules

Caregiver sleep is heavily fragmented (overnight monitoring, early-morning caregiving, on-call status). Low-dose melatonin supports circadian alignment in the limited windows you have for sleep. The high-dose OTC versions (5–10 mg) sedate without realigning the clock and increase next-day grogginess — exactly what you don't need.

Saffron 30 mg/day as a mood adjunct

Multiple RCTs support saffron as a mild-moderate depression adjunct with effect sizes approaching some prescription antidepressants. Reasonable trial in mild caregiver depression as adjunct to therapy. Take it with prescriber awareness if on antidepressants — additive serotonergic effects.

Glycine 3 g at bedtime for sleep quality

For caregivers whose problem is poor sleep quality and next-day fatigue (rather than sleep onset), glycine has the cleaner trial evidence than melatonin. Cheap, well-tolerated, taste is mildly sweet, dissolves easily in water.

Creatine 3–5 g/day for cognitive performance under sleep restriction

Recent meta-analyses support creatine's cognitive effects, particularly under sleep deprivation — the caregiver-specific use case. Also preserves muscle mass during the inevitable physical-activity reduction of intensive caregiving.
