When “Normal” Isn’t Enough: Precision Nutrition for a Sharper, Healthier Brain

Most of us accept signs such as occasional forgetfulness as part of aging. But growing evidence suggests that what we consider “normal”—especially for key nutrients like vitamin B12 or omega‑3 fatty acids—might not actually be optimal for brain health.

Rethinking B12 Standards

A recent UCSF study in Annals of Neurology looked at “active” B12 in adults over 70—and found that even those with B12 levels sitting at the low end of the official “normal” range processed information more slowly and had more damage to the brain’s communication pathways than individuals with higher levels. In other words, meeting the standard Nutrient Reference Value (NRV) for B12 may not be enough to keep your mind sharp. Doctors are prescribing higher B12 doses—well above the Daily Reference Value (DRV)—to patients who show any sign of mild mental decline.

DO‑HEALTH: Omega‑3 + Vitamin D + Exercise Slow Epigenetic Aging
A three-year European trial, the DO-Health trial,  involving 777 adults aged 70+ showed that daily omega-3 (1 000mg), Vitamin D (2,000 IU), and exercise collectively slowed the pace of aging by about 10% . Notably, omega-3 supplementation alone delivered a similar effect, underlining the importance of both nutrient type and dosage in supporting Brain Health.
Precision Matters: Form, Dose, Frequency

These two reports share a common theme: dosage matters. It’s not just “take B12 & fish oil”, it’s “how much should I take”. The dosage can determine whether these nutrients get to where they can truly support the brain.

What You Can Do Today

  1. Ask for active B12 test if you’re over 60 and notice mild cognitive changes and/or increase your B12 intake from food or supplementation.

  2. Choose high quality, strong Omega‑3 supplements, at least 1g of Omega 3 per day. The EU approves claims that 250mg of DHA and 250mg EPA aids Vision, Brain and Heart).

  3. Combine nutrient support with healthy habits like regular exercise and vitamin D—from diet or supplement—to support both brain and DNA health.

  4. Monitor your progress, through focus, memory retention, and daily clarity.

Conclusion: Aging Doesn’t Have to Mean Fading

Shifting from “normal” to “optimal” nutrient intake levels could be one of the most effective ways to preserve mental performance as we get older.

The days of ‘Little of Everything, Lots of nothing‘ supplementation are over. Focused supplementation in the right dosages is the way forward.
