Longevity Basics: How a Multivitamin, Creatine, Omega-3 and Shilajit Fit Together

A look at four commonly paired foundation ingredients, what research has examined for each, where the evidence is strongest and thinnest, and who should speak to a doctor first.

Conversations about longevity tend to jump straight to exotic ingredients. In practice, most of the research on food supplements and long-term health concerns a few well-studied nutrients taken consistently alongside a varied diet, sleep, training and regular check-ups. This article looks at four ingredients that are often grouped together as a daily foundation: a multivitamin, creatine monohydrate, EPA and DHA from fish oil, and shilajit resin. It describes what each one is, what research has looked at, and where the limits of the evidence sit.

The foundation: a multivitamin and omega-3

A broad multivitamin is best understood as a safety net rather than a performance tool. Certain B vitamins, magnesium, iron and vitamin C contribute to normal energy-yielding metabolism, which is simply the process of turning food into usable energy. A multivitamin cannot make up for a poor diet, but it can narrow small gaps, which may be relevant for people who travel often, eat irregularly or follow restricted diets.

EPA and DHA are the long-chain omega-3 fatty acids found in oily fish. Regulators in Europe recognise that EPA and DHA contribute to normal heart function at an intake of around 250 mg per day, and that DHA contributes to normal brain function and vision. Observational studies link regular fish intake with better long-term cardiovascular outcomes, although trials of fish oil capsules have produced mixed results. That is a good reason to treat fish oil as a complement to oily fish and walnuts, not a replacement for them.

• Check the label for the actual EPA and DHA content per serving, not just the total oil, because the two figures can be very different.
• Take fish oil with a meal containing some fat, which research suggests improves absorption.
• If you eat oily fish twice a week, you may already be close to the commonly cited intake.

Creatine: the most studied ingredient in the group

Creatine is stored in muscle and, to a lesser extent, in the brain, where it helps regenerate the cellular fuel used for short, intense efforts. Daily creatine intake of 3 g or more contributes to physical performance in successive bursts of short-term, high-intensity exercise in adults. Because it has been studied for decades, creatine monohydrate is generally regarded as the reference form, and more elaborate forms have not shown a clear advantage.

Research is also exploring creatine in relation to muscle maintenance with age and to cognition, but those areas are still developing and should not be read as established benefits. Two practical points are worth knowing. Creatine can increase water held within muscle, so a small rise in body weight is common, and it can raise serum creatinine on a blood test without necessarily reflecting a change in kidney function. If you have a blood test booked, mention that you take it.

The most useful question about any supplement is not what it promises, but how well its effect has actually been studied.

Shilajit: traditional use, modern questions

Shilajit is a mineral-rich resin collected from rock layers in mountain regions, and it has a long history in traditional Ayurvedic practice, where it is valued for everyday vitality and stamina. Its fulvic acid content is of scientific interest, but the human evidence is much thinner than for creatine or omega-3, with a small number of short studies. Descriptions should therefore stay at the level of traditional use and early research.

Quality matters more here than for most ingredients, because raw shilajit can carry heavy metals if it is not properly purified. Look for evidence of purification and independent testing for heavy metals before choosing a product.

Who should speak to a doctor first

Food supplements are not medicines and are not intended to diagnose, treat, cure or prevent any condition. If you are pregnant, breastfeeding, taking medication, or managing a medical condition, speak to a doctor before starting any supplement. Fish oil can be relevant for people taking blood-thinning medication, creatine deserves a conversation for anyone with kidney concerns, and shilajit is best discussed with a clinician if you have an iron-related or autoimmune condition.

Putting it together sensibly

A sensible approach is to start with the basics, keep the routine simple enough to follow every day, and review it after a few months alongside your diet and any blood test results. Consistency matters more than adding further ingredients. Taking everything at one meal, ideally with food, is usually the easiest way to build the habit.
