Metabolic Flexibility
Metabolic flexibility is your body’s ability to switch efficiently between two fuels, glucose (when food is eaten) and fat and ketones (from storage). A flexible metabolism moves between the two without energy crashes or cravings. For example, a hypoglycemic crash would not occur if the body could shift over properly from using glucose to using fats and ketones. The shift from glucose to ketones depends on nutrients like magnesium and the B vitamins. TruDiagnostic’s TruHealth panel reads a ketone metabolism marker and reports it as a percentile, where higher means a profile more consistent with efficient fuel switching. Because it reflects daily fuel and cofactor nutrient status, this marker can be altered within months.

“Your cells are tiny engines, and minerals are the spark. Give the body what it needs and it remembers how to burn fuel cleanly.”
Participants improved their ketone metabolism marker on the TruHealth panel over six months. The largest ketone move was from the 19th to the 88th percentile.
Behind that number are ten everyday people, ages 34 to 79. Fuel switching is one of the most responsive markers on the panel, so it is where some of the clearest movement was reported. Here are two participants, one with the strongest result in the group and one story about how a fuel marker can climb even under stress.

Helen’s ketone metabolism marker rose from the 19th to the 88th percentile, the largest ketone shift in the group. Over the same six months she was also the strongest overall responder on the deeper age clocks.

Steven’s six months were hard. He went through an intense detox (not part of the study protocol) that hospitalized him, and his deeper age clocks rose during that crisis, which the study reports openly. Even so, his ketone marker climbed from the 30th to the 79th percentile, a sign the fuel system was shifting, under the influence of the proper nutrients, while the rest of the body was still healing.
Fuel switching runs on having enough minerals. ReMag® leads, with multimineral ReMyte® and the B Vitamins. The full Maui ReSet Bundle gives an added level of support. Swipe to see each.
ReMag®
Highly-absorbed picometer-sized stabilized magnesium ions, required cofactors for insulin signaling and for the enzymes that handle glucose. Steady magnesium status helps the body move between fuels without the swings.

ReMyte®
Twelve stabilized highly-absorbed trace mineral ions, including chromium and zinc that support the glucose and insulin machinery. Trace mineral sufficiency underpins how well the body reads and responds to fuel.

ReAline®
Methylated and food-based B vitamins with amino acids L-methionine and L-taurine. Methyl folate, methylated B12, B2, and B6 and the methyl group in L’methionine are invaluable precursors in the methylation pathways that are needed to build and maintain DNA which in turn affects development, aging, and the regulation of gene activity.

The science of nutrition and synergy
Metabolic flexibility rests on mineral sufficiency. Magnesium is a required cofactor in insulin signaling and in the enzymes that handle glucose. In pooled clinical trials, magnesium supplementation improved fasting glucose and insulin sensitivity markers in people with or at risk of diabetes, and a separate trial found that magnesium improved insulin sensitivity even in non-diabetic, normal magnesium adults. Magnesium deficiency is a well-known risk factor for prediabetes and diabetes as described in medical texts. When the body reads and uses glucose well, and has magnesium to assist, it can switch to stored fat and ketones more cleanly when food is scarce.
Trace minerals add to the picture. In adults with impaired glucose tolerance, supplementing chromium with magnesium improved glucose and insulin measures more than either mineral alone. The evidence for chromium on its own is mixed, and clearest in people who begin with a deficiency or who have a glucose problem, which is why we frame minerals as needing to be sufficient or optimal rather than given as a treatment.
B vitamins play a crucial role in glucose handling and ketone metabolism by acting as coenzymes in metabolic pathways that convert carbohydrates into glucose and facilitate energy production. They are essential for processes like glycolysis and the Krebs cycle, which are vital for utilizing glucose and producing ketones during fasting or low-carbohydrate intake.
Commonly asked questions
What is metabolic flexibility, and why does it matter for aging?
Metabolic flexibility is your body’s ability to switch between fuels, as it uses glucose after meals from your diet and pulls fat and ketones out of storage between meals. A flexible metabolism moves between the two without energy crashes like hypoglycemia with sugar cravings as a result. As we age this switching can stiffen, so keeping it responsive is part of a healthy aging picture and dependent on nutrient cofactors.
What does the ketone marker on a TruHealth report mean?
It is an epigenetic signature associated with the body’s ability to maintain ketone body metabolism, reported as a percentile from 0 to 100 where higher is more favorable. A rising percentile suggests a profile more consistent with efficient fat and ketone use. It is a trend to watch over time rather than a single lab value.
Can minerals really affect how my body handles fuel?
Magnesium is a required cofactor for insulin signaling and glucose handling, and clinical trials associate magnesium sufficiency with better insulin sensitivity. Trace minerals such as chromium add support, with the clearest effects in people who are deficient at the outset. These are modest, optimum level effects, not a treatment, and results vary from person to person.
How can a ketone marker improve even when other readings do not?
Different markers move on different timelines, and the panel reports each one independently. One participant’s deeper age clock got older during a hard detox period, and yet his ketone marker climbed sharply, a sign his fuel system was shifting while the rest of the body was still healing.
Will these formulas put me in ketosis or lower my blood sugar?
No. These are nutrients and they do not force ketosis. The Maui ReSet Bundle (Cell Nutrient Stack on rnareset.com) supports the normal daily nutrient sufficiency your metabolism runs on, part of an optimum approach to steadier fuel switching over time.
