The combinations the trials actually measured.

Five pairings in this formula have been studied as combinations in human trials. Each finding below is what a named study measured, cited and dated, never written by the brand.

• Iron + Vitamin CAbsorption

  In a controlled radioiron study in 63 men, adding ascorbic acid to a non-heme iron meal increased iron absorption in proportion to the dose, from about 1.6 times the meal alone at 25 mg to about 9 times at 1000 mg.

• Calcium + MagnesiumStrength

  In a 12-month randomised, double-blind trial, 98 adults aged 50 and over drank a litre a day of either a naturally calcium- and magnesium-rich mineral water or a low-mineral water. The mineral-rich group had fewer falls at the 6-month assessment and higher appendicular muscle mass, with the minerals delivered as drinking water rather than a capsule.

• Folate + Vitamin B12 + Vitamin B6Heart

  In a 2025 network meta-analysis of 16 randomized trials in healthy adults, folic acid taken together with vitamins B6 and B12 lowered blood homocysteine more than any single supplement, with the 1 mg folic acid plus 7.2 mg B6 plus 20 micrograms B12 arm ranked most effective versus placebo (mean difference -1.03 micromol/L, 95% CI -1.71 to -0.36).

• Magnesium + Vitamin B6Calm

  In an 8-week randomized trial of 264 stressed healthy adults with low magnesium, magnesium plus vitamin B6 and magnesium alone reduced perceived stress about equally overall. In the prespecified subgroup that started with severe stress, the combination improved stress scores 24% more than magnesium alone.

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.

• Vitamin Cwithin 24 hours of a single doseMeasured within a day

  In a randomised crossover trial, 12 healthy adults consumed 101.7 mg of vitamin C as a powder, as raw fruits and vegetables, or as juice, and plasma vitamin C rose after every intake form, with plasma and urinary levels tracked over the 24 hours following the single dose.

• Vitamin D3about 3 months of daily useBuilds with daily use

  In the trial record, blood vitamin D rises for about 3 months of daily vitamin D3 and then holds at a plateau, near 69 nmol/L at 1,000 IU a day, from a starting level near 41 nmol/L.

• Vitamin Eabsorbed slowly, tracked over 72 hoursMeasured within a day

  In a 3-phase crossover using two deuterium-labelled forms of alpha-tocopherol, healthy women absorbed about 55 percent of an oral dose taken with a 40 percent fat meal and about 64 percent with a fat-free meal, with samples tracked over 72 hours. The authors conclude absorption is not limited by absent fat or fasting, and that vitamin E leaves the intestine by a prolonged process.

• Vitamin Kabout four weeks of daily useBuilds with daily use

  A double-blind randomised dose-finding trial gave 60 postmenopausal women aged 50 to 69 either 0, 50, 100 or 200 micrograms of menaquinone-7 daily for four weeks on a controlled diet. The ratio of carboxylated to undercarboxylated osteocalcin rose dose dependently, with significant differences from the 0 microgram group at 100 and 200 micrograms. A companion 12-week trial in 120 people aged 20 to 69 confirmed the change at 100 micrograms daily. Both studies were run by authors affiliated with the R and D division of J-Oil Mills. An independent 8-week double-blind trial in 55 healthy prepubertal children found the same direction at 45 micrograms daily. What was measured is a blood marker of vitamin K status, not bone density and not a sensation.

• Vitamin Kthree years of daily use, with measurements at one, two and three yearsBuilds with daily use

  A double-blind randomised trial gave 244 healthy postmenopausal women either placebo or 180 micrograms of menaquinone-7 daily for three years, with bone mineral density measured by DXA at baseline and after each year. Menaquinone-7 decreased the age-related decline in bone mineral content and bone mineral density at the lumbar spine and femoral neck, but not at the total hip. The effect is a slowed decline rather than a gain, and the trial ran three years rather than weeks.

• Thiaminabout 18 to 30 days of restricted intakeBuilds with daily use

  In the controlled depletion study the EFSA reference opinion reviews, restricting thiamin intake to 0.009 to 0.015 mg/MJ for 30 days brought urinary free thiamin excretion from a mean of 0.283 mg/24 h down to undetectable levels by day 18 of the depletion period.

How each ingredient usually behaves over time.

12 ingredients, from each one's own page.

• Vitamin AWeeks, not days

  Weeks to months. Liver stores buffer intake, so vitamin A status moves slowly and shows up on a blood panel rather than as a sensation.

• Vitamin CWithin hours

  Blood levels rise within hours and tissue pools fill over days. Collagen-linked changes in skin and gums build over weeks and show as tissue quality, not as a sensation.

• Vitamin D3About six to twelve weeks

  25-hydroxyvitamin D climbs over roughly six to twelve weeks of daily dosing before it plateaus. It's a blood level you watch rather than a feeling.

• Vitamin EWeeks, not days

  Plasma alpha-tocopherol climbs within days of daily intake, and anything you'd notice in skin condition is a slow change across a couple of months.

  Its own page, the plain answer on timing ↗

• Vitamin KWithin days

  Clotting factor carboxylation responds within days. The bone marker undercarboxylated osteocalcin shifts across roughly four to twelve weeks, so this shows up on a panel.

• Thiamin

  There is no onset to time in the usual sense. Status markers such as erythrocyte transketolase activity move across weeks, and that is where the change is read.

The same ingredient, carried differently.

What each form is, and where it fits in a formula. Measured findings carry the study that reported them.

• Cholecalciferol (vitamin D3)

  The animal-sourced form of vitamin D, made in skin under UVB light and produced commercially from lanolin. Fat-soluble, so it travels with dietary fat and is stored in body fat.

  Fits

  Raising and holding vitamin D status, and the form most supplement trials use.

  Trade-off

  Being fat-soluble it accumulates with sustained high dosing, so intakes are set against the tolerable upper level rather than topped up freely.

  In a 12-week double-blind randomised controlled trial in 108 young women in urban Bangalore, most of whom began vitamin D-deficient, daily vitamin D3 at 400, 600 or 800 IU in a fortified wafer raised serum 25-hydroxyvitamin D, parathyroid hormone fell over time, and effects on bone-turnover markers were modest and not dose specific. The 800 IU dose brought 65 percent of participants to sufficiency.

  Peris et al., 2026 (Nutrients)PMID 42124077
• Riboflavin

  The free vitamin B2 molecule, an isoalloxazine ring joined to a ribitol sugar chain, supplied as the unmodified crystalline compound with no added salt or phosphate group.

  Fits

  It is the form most panels list simply as riboflavin or vitamin B2.

  Trade-off

  It is intensely yellow and only sparingly water soluble, so it can tint a finished product and tends to resist dissolving cleanly in a liquid or a fast-melt format.

• Nicotinic acid

  The free-acid form of vitamin B3, pyridine-3-carboxylic acid. It is the reference form of niacin, a small water-soluble molecule carrying a bare carboxylic acid group on the pyridine ring.

  Fits

  The long-standing reference form for meeting a vitamin B3 requirement.

  Trade-off

  This is the form behind the familiar warm, tingling skin flush that many people notice soon after a larger dose, a recognized property of the free acid that leads some formulators to reach for an amide or ester instead.

• D-pantothenic acid

  The free acid form of vitamin B5, an amide of pantoic acid and beta-alanine, supplied as a viscous hygroscopic oil or a stabilised liquid rather than a dry salt.

  Fits

  The un-neutralised acid carries no mineral counterion, so it suits liquid drops, syrups and formats where a calcium or sodium salt is not wanted.

  Trade-off

  It is hygroscopic and tends to draw water and turn sticky, which makes it awkward to hold as a dry powder without added stabilisers.
