Is it safe to take longevity supplements when you don’t actually know if you need them?

The question, asked by a man aged 30 to 44

I’ve been looking at different longevity supplements and therapies, but I’m worried about taking things unnecessarily. Could some of these actually cause problems if your blood tests and health history haven’t been properly assessed?

It is good to be cautious. Taking any random supplements is not a solution; some can be harmful if taken without a doctor’s consultation.

Too much vitamin D and iron can increase to a harmful level.

Fish oil with blood thinners can increase bleeding.

Certain supplements can hide the real reason for a deficiency, like low B12, which is caused by a gut issue.

Distorted test results lie; biotin can make thyroid tests look normal.

Not every supplement is true to its label.

Suggested Tests

  • Vitamin D,
  • Vitamin B12 and folate
  • Ferritin and iron studies
  • Serum magnesium, zinc and calcium
  • Omega-3 index
  • Liver function tests
  • Kidney function tests
  • TSH and free T4
  • HbA1c
  • A full review of current supplements and medications

Lifestyle & Nutrition Tips

  • Before supplementing, go for a food-first approach. Most of the nutrients your body needs are easily available through food.
  • Don’t randomly take any supplement just because of the label. Consult with a doctor first.
  • A longevity routine should be built around strength, sleep, exercise, nutrition, and recovery.
  • Using supplements should be done if there is a deficiency and if necessary.
