Your DNA results, translated honestly.

The most-Googled gene in consumer genetics, and the most over-sold. Here's the version without the panic.

MTHFR gets all the press. Its partner enzyme, MTRR, does the other half of the methylation work, and almost nobody talks about it.

Your body makes some of its own choline. This gene sets how much, and whether your plate has to make up the difference.

The gatekeeper that pulls folate into your cells

Same dose, different blood level. The receptor is part of the reason.

You can get plenty of vitamin D and still test low, if the protein that ferries it around isn't pulling its weight.

Two genes can leave you short on vitamin D. This one runs the switch that turns it on.

The gene that decides how much vitamin A you actually get from carrots.

Your body can't make vitamin C. This gene decides how much of it sticks around.

TMPRSS6 leans you a little toward lower iron. But iron is one of the few nutrients you can actually take too much of, so the right first step is a blood test, not a supplement.

Some people eat plenty of fat and carbs and their triglycerides barely move. This variant says you're probably not one of them.

Two tiny letters decide how much your LDL moves when you eat butter.

The CC variant at rs5082 changes how your body processes saturated fat through gene expression, not just calorie counting.

Flax and chia hand you ALA. Your body still has to convert it into the omega-3s that work, and this gene sets how well that goes.

CETP variants are among the strongest genetic signals for HDL cholesterol in the human genome. One of the most replicated findings in lipid genetics.

One liver enzyme clears most of your caffeine, and the version you carry decides how long that afternoon coffee sticks around.

If you only ever look up one blood-sugar variant, make it this one. It hits harder than the rest.

A genetic tendency toward higher intake that responds to specific environmental inputs.

The enzyme that mops up the free radicals your own energy production makes.

The recycler behind your CoQ10's antioxidant punch.

One small DNA swap sets how briskly your antioxidant enzyme answers when selenium shows up.

Unlike a normal SNP, GSTM1 is present or missing — a whole-gene deletion. That makes it interesting, and it makes it hard for a consumer DNA file to read.

One stop codon decides whether your fast muscle fibers are built for the sprint or the long haul.

One amino acid, sold as a fat-loss verdict. The real effect is small, and the move is mostly the same either way.

One gene, one common typo, and a real difference in how your brain banks the benefits of a workout.

One letter decides whether your prefrontal dopamine gets cleared fast or lingers.

Almost every mammal stops digesting milk after weaning. Whether you're an exception comes down mostly to one variant.

One gene decides whether your blood B12 reads high for a reason that has nothing to do with how much you absorb.

The gene that decides whether kale tastes green or like soap.
