How we verify

The brand submits the formula. We read the supplement facts panel and weigh dose, form and synergy against the clinical evidence. Labs test. IngredientMD verifies. The fee pays for review time, never for the outcome.

    We read the label.

    The panel on the left is the one we evaluated, line by line.

  2. 02
    Every active, separately.

    All 1 actives checked against the clinical evidence: dose, form, and what the research actually shows.

    Then the formula as a whole.

    Doses, ratios, and how the ingredients work together. That assessment is the verdict above: "Backed by human trials".

  4. 04
    Earned, not bought.

    The verdict is public and identical whether or not a brand pays. A formula that does not clear the bar gets nothing.

The gap this formula speaks to.

Public health figures the engine matched to this formula's ingredients. Reported by their source, cited and dated, never written by the brand.

The people it speaks toFieldwork 2011

12.7% of US adults aged 60 and over

in 21 states reported increased confusion or memory loss in the preceding 12 months, in the 2011 Behavioral Risk Factor Surveillance System.

The people it speaks toPublished June 2019

More than 1 in 4 US adults aged 50 to 73

regularly take a supplement for their brain health, rising to 36% of those over 74, and memory is the reason 71% give, in AARP's 2019 survey.

Meta-analysis, 2024

Across randomised trials, diets enriched with pure medium-chain triglycerides lowered body weight by about 1.6% more than diets built on long-chain fats in adults carrying excess weight.

Meta-analysis, 2015

Pooling 13 trials in 749 adults, replacing long-chain fats with C8 and C10 medium-chain triglycerides lowered body weight by about 0.5 kg and waist circumference by about 1.5 cm, with no change in blood lipids.

Meta-analysis, 2026

Across trials of exogenous ketone sources, raising blood ketones was linked with small improvements on some cognitive measures, varying by group and task.

Caprylic Acid Triglycerides

Randomised trial, 2023

Over 12 weeks in sedentary middle-aged and older adults who also walked, knee extension strength rose more in every group taking medium-chain triglycerides made of octanoic and decanoic acid than in the control group, and grip strength rose from baseline at 6 g a day.

Randomised trial, 2026

In healthy adults, adding glucose alongside medium-chain triglycerides reduced the rise in blood ketones compared with the triglycerides taken alone.

Every one of these is a fact the engine could ground.

Each line below was derived from this formula's own record at the time of verification. Nothing here was written by the brand, and nothing can be added that the evidence does not carry.

What the trials show

What the trials show about timing.

Time-to-effect windows the engine read from the trial record. Each is a window a named study measured, cited and dated, never written by the brand.

  • Caprylic Acid Triglyceridesblood ketones rise within about 4 hoursMeasured within a day

    In a 6-arm crossover, 15 healthy volunteers aged 65 to 73 took test fats after a 12-hour fast with ketones measured over the following 4 hours. A 20 g dose of caprylic acid (C8), the medium-chain fatty acid the ketogenic effect is mainly demonstrated for, raised blood beta-hydroxybutyrate relative to a sunflower-oil control, and coconut oil, which is about two thirds medium-chain triglycerides, raised it less per gram.
