Know your heart: nutrients, foods and when to see a doctor

FirstShield guide: nutrients for your heart

Your heart beats around a lakh times a day. Diet, activity and a few nutrients help keep it working well.

Nutrients that support your heart

Omega-3 (fish oil)

The EPA and DHA fats in fish oil support the heart and brain.

  • How much you need: No official allowance; supplements usually give 250–1,000 mg EPA + DHA a day.
  • Best food sources: Oily fish (mathi/sardine, mackerel), walnuts, flaxseed.

Be careful:

  • On blood thinners (warfarin, clopidogrel, aspirin): ask a doctor — more bleeding risk.
  • Fish allergy: avoid fish oil.

Coenzyme Q10

Helps cells make energy; often taken by people on statin (cholesterol) tablets.

  • How much you need: No official allowance; supplements usually 100–200 mg a day.
  • Best food sources: Meat, fish, nuts, whole grains.

Be careful:

  • Can weaken warfarin — ask a doctor.
  • Not in pregnancy without advice.

Magnesium

Needed by muscles and nerves, for a steady heart rhythm, and for bone.

  • How much you need: Men 440 mg, women 370 mg a day (ICMR-NIN 2020).
  • Best food sources: Nuts, seeds, whole grains, pulses, green leafy vegetables.

Be careful:

  • Kidney disease: not without a doctor.
  • Can loosen stools.

Everyday habits that help

  • Exercise daily
  • Healthy diet, less salt

When to see a doctor: Supplements never replace BP, sugar or cholesterol medicines. Chest pain is an emergency.

Before you take any supplement

  • Supplements fill a gap in the diet; they do not treat disease. Anyone with a diagnosed condition (diabetes, kidney, liver or heart disease) or on regular medicines should ask their doctor first.
  • Doses here are for ADULTS. Children’s and pregnancy supplements are chosen by the doctor.
  • Only products made entirely of nutrients are suggested (vitamins, minerals, probiotics, amino acids, plant extracts) — anything that also contains a drug is left out.
  • Daily amounts are the ICMR-NIN 2020 recommended dietary allowances where one exists; more is not better.
  • Products are listed focused-first (1–3 ingredients), then multivitamins, each by how often our shops sold it — a multivitamin may carry only a small amount of a given nutrient.
