Thousands of genetic variants.

Covering every system that shapes your health, from metabolism and inflammation to heart and brain health.

BASIL is powered by a growing library of genetic trait reports, each a unique insight into a facet of your biology.

Beyond your DNA

Refined by more than genetics.

Your DNA is the starting point. BASIL layers in your biometrics, bloods, behaviours, diagnoses and lifestyle to sharpen every trait — so your plan reflects the whole picture of you.

Biometrics such as resting heart rate, VO₂ max and body composition that sharpen how each trait applies to you
Biometrics

Your body's numbers

Resting heart rate, VO₂ max and body composition help make your results more precise.

Blood markers — cholesterol, glucose, inflammation and hormone panels — that add a real-time layer to your genetic risk
Bloods

Your blood markers

Cholesterol, glucose, inflammation and hormone panels add real-time detail to your genetic results.

Behaviours like how you train, sleep and recover that tune every recommendation to how you actually live
Behaviours

Your daily habits

How you train, sleep and recover tunes every recommendation to how you actually live.

Everyday lifestyle context — diet, activity, stress and environment — that frames your genetic results
Lifestyle

Your everyday life

Diet, activity, stress and environment shape your results, so guidance fits how you actually live.

Anatomy of a report

Each health trait. A plan to act on.

This is a real FitnessGenes trait report. Every one of your 180+ reports follows the same structure — your result, the science behind it, and the actions that follow.

Supportive Trait

You carry gene variants that suggest you produce lactase in adulthood and can tolerate lactose.

Can you tolerate lactose?

Archaeological evidence suggests humans have been drinking cow's milk since at least 9,000 BC. One of its main nutrients is the sugar lactose, which we break down using an enzyme called lactase. As babies we produce high amounts of lactase; as adults, however, we stop producing it.

In the last 6,000 years or so, some humans acquired mutations that let them keep producing lactase into adulthood. This "lactase persistence" spread quickly, helping people survive famines on cow's milk and making them less likely to suffer the effects of lactose intolerance, such as bloating.

This trait looks at variants around the lactase gene (LCT), which determine whether or not you produce lactase into adulthood. This may affect your ability to tolerate lactose, although other factors are important too.

3 The science, explained
About two thirds of us stop producing lactase after weaning during infancy — this is known as 'lactase non-persistence.'
Some of us continue to produce lactase in adulthood — this is known as 'lactase persistence.'
Lactase persistence is strongly determined by our LCT (lactase) gene. The 'T' variant (rs4988235) is the main LCT variant that causes lactase persistence in people of Eurasian ancestry.

Supplements

If you experience symptoms from consuming lactose, you may want to try having a lactase enzyme tablet with dairy products

These tablets aid digestion of lactose, so will help you tolerate dairy better.

Nutrition

Try to have 3 servings of dairy each day

Milk is full of calcium, phosphorus, magnesium and protein — all essential for healthy bones. Adequate dairy throughout life can strengthen bones, protecting against age-related declines.
