Peer-reviewed analysisVitamin C is the lead active here, studied most for iron status. 20 human studies on Vitamin C back this formula, each one cited. Each serving carries 2,625 mcg of Vitamin A, inside the range the published research used. Who it fits: made for women, adults.
Verified by IngredientMDThe panel on the left is the one we evaluated, line by line.
All 23 actives checked against the clinical evidence: dose, form, and what the research actually shows.
Doses, ratios, and how the ingredients work together. That assessment is the verdict above: "Strong evidence, strong dose".
The verdict is public and identical whether or not a brand pays. A formula that does not clear the bar gets nothing.
Read by the engine against 2.1 million data points from clinical trials, PubMed and more than a hundred vetted sources. No individual reviewer is named or implied.
Cross-checked against 7,174 documented interactions for these actives.
Public health figures the engine matched to this formula's ingredients. Reported by their source, cited and dated, never written by the brand.

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.
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.
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.
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.
In the same depletion and repletion record the EFSA reference opinion reviews, erythrocyte transketolase activity fell progressively to about 75% of baseline during the 30-day depletion period and returned to its baseline value after 1 week of thiamin repletion.
In an intervention the EFSA reference opinion reviews, adults whose baseline riboflavin intake and status were unknown received 5 mg/day of riboflavin for 8 weeks, and haemoglobin concentration, haematocrit and erythrocyte count all rose significantly over that period.
An expert consensus on vitamin B6 use, developed by a six-member Delphi panel with a structured evidence-quality assessment, calculated from pharmacokinetic parameters that complete clearance of vitamin B6 from the body takes a washout period of about 20 to 40 days after intake stops.
A systematic review and Bayesian meta-analysis drew on 108 articles from 14,002 screened records and modelled blood folate against folic acid intake using one-compartment pharmacokinetic models. Red blood cell folate rose 1.78 fold from baseline to steady state at 375 to 570 ug folic acid per day, and reaching that steady state took a median of 36 weeks, 95% credible interval 27 to 52 weeks. Serum or plasma folate rose 11.6% for every 100 ug per day of folic acid intake, 95% credible interval 8.4 to 14.9.
A kinetic study in six healthy men aged 22 to 31 gave 3.6 umol per day, 1.6 mg, of deuterium-labelled folic acid for four weeks, with folate tracked in serum, erythrocytes and urine by microbiological assay and gas chromatography mass spectrometry. Serum folate reached its maximum concentration in about 18 days, while isotopic labelling of erythrocyte folate kept rising across the whole four weeks. After supplementation stopped, red blood cell folate and urinary folate excretion declined linearly, and serum folate fell with a slow-phase half-life of 18.7 days. One study, six men, no control group.
A randomised, double-blind, parallel-group dose-finding trial in 120 older people with mild vitamin B12 deficiency, defined as serum B12 of 100 to 300 pmol/L with methylmalonic acid at or above 0.26 umol/L, gave daily oral cyanocobalamin at 2.5, 100, 250, 500 or 1000 ug for 16 weeks. Mean plasma methylmalonic acid fell 16%, 16%, 23%, 33% and 33% across those doses. Daily doses of 647 to 1032 ug accounted for 80% to 90% of the estimated maximum reduction. The window was measured on a blood marker of B12 status, not on a symptom.
An open-label randomised single-dose pharmacokinetic study in 20 healthy men aged 20 to 45, conducted and authored by staff of Emisphere Technologies, the developer of the SNAC carrier under test, measured serum vitamin B12 after one 5 mg cyanocobalamin tablet, with six men on the marketed tablet. Time to peak serum B12 was 6.83 hours for the marketed tablet and 0.5 hours for the carrier coformulation. Absolute bioavailability was 2.16% and 5.09% respectively. One trial, six men per arm. Serum concentration was measured, not any symptom.
In an open trial with no placebo arm, 71 patients with brittle or splitting fingernails took 2.5 mg of biotin a day. Of the 45 cases that could be evaluated, 41 were rated as having firmer and harder nails after an average of 5.5 months of treatment, standard deviation 2.3 months. The rating was clinical judgement rather than an instrument reading, and there was no control group, so the window describes when the raters recorded change, not a placebo adjusted effect.
In a controlled feeding study, lactating women randomised to 480 or 930 mg choline per day for 10 to 12 weeks showed that the higher intake increased breast milk choline content by raising output of endogenously synthesised choline metabolites.
A randomised cross-over trial in ten women of mean age 69 gave a single 500 mg dose of calcium as citrate fasting, citrate with a meal, fortified juice or a dairy product meal, with blood drawn before and at 1, 2, 4 and 6 hours. Serum ionised and total calcium increased significantly from baseline over six hours, with the rise similar after fortified juice, delayed when citrate was taken with a meal and smaller after the dairy meal. A separate double-blind cross-over trial in 25 postmenopausal women measured parathyroid hormone and a bone resorption marker 12 hours after a single calcium dose. Ten participants is a small sample, and what moved was blood chemistry, not a sensation.
In a 24 week randomised double-blind placebo-controlled trial in 112 mildly iodine-deficient New Zealand adults aged 18 to 40, 150 micrograms of iodine a day as potassium iodate lowered thyroglobulin, a blood marker of iodine status, by 12 percent at 8 weeks, 20 percent at 16 weeks and 27 percent at 24 weeks compared with placebo. Median urinary iodine reached 168 micrograms per litre against 79 on placebo. TSH and free T4 stayed within normal range and did not change significantly.
Across three randomised placebo-controlled trials pooled as individual patient data (199 adults with naturally acquired colds, 80 to 92 mg of elemental zinc a day as acetate lozenges), 70 percent of the zinc group had recovered by day 5 against 27 percent on placebo, and colds ran 2.73 days shorter against a 7 day average duration. A separate meta-analysis of seven lozenge trials (575 participants, doses above 75 mg a day, zinc acetate or zinc gluconate) measured cold duration 33 percent shorter, with no significant difference between the two salts.
In a controlled feeding study in nine healthy men, six weeks of restricted zinc intake raised DNA strand breaks in peripheral blood cells, and four weeks of repletion at 11 mg a day, with 20 mg of supplemental zinc for the first seven days, reversed the rise. In a separate randomised placebo-controlled trial in 40 Ethiopian women eating a high-phytate diet, 20 mg a day of zinc sulfate for 17 days lowered mean comet tail moment from 39.7 to 30.0 while plasma zinc did not change significantly. Both windows were measured on a DNA damage marker in blood cells, not on a symptom.
In a 12 week randomised double-blind placebo-controlled trial in 119 healthy UK adults aged 50 to 64, mean plasma selenium rose from 95.7 ng/mL at baseline to steady state by week 10, reaching 118.3, 152.0 and 177.4 ng/mL on 50, 100 and 200 micrograms a day of selenium-enriched yeast. Plasma selenoprotein P rose in every selenium arm. Platelet glutathione peroxidase activity did not change significantly at any dose or form.
In an 8 week pilot with a parallel placebo group, 8 young women taking 2 mg of copper a day as copper glycinate showed a 9 percent mean rise in serum ceruloplasmin and a 75 percent rise in diamine oxidase, alongside a 39 percent fall in plasma F2-alpha isoprostanes. Erythrocyte copper-zinc superoxide dismutase did not change. In a separate 4 week double-blind crossover in 20 men with moderately high cholesterol at the same 2 mg a day, copper moved no measure across the whole group and raised superoxide dismutase and diamine oxidase only in the 10 men who started below the median. Both are small and both measured enzymes in blood, not a symptom.
The same eight healthy men then took 10 mg of boron daily with breakfast for seven days, with an 8 a.m. blood draw on day seven. Mean plasma free testosterone increased and mean plasma estradiol decreased significantly, while dihydrotestosterone, cortisol and vitamin D were elevated and all three inflammatory markers fell. The authors describe this as the first human report of a rise in free testosterone after boron intake. There is no placebo arm across the seven days and the sample is eight men, so the one-week figure rests on a single small study.

12 ingredients, from each one's own page.
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.
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.
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.
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.
For undercarboxylated osteocalcin to shift. It is a blood marker of carboxylation rather than something that registers as a sensation.
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.
Urine turns bright yellow within hours of the first dose. Status itself, read as red cell glutathione reductase activity, shifts across two to eight weeks.
Nothing to wait for at everyday amounts. Niacin status shows up on blood work rather than as a sensation. The flush from the nicotinic acid form arrives within 30 minutes.
Nothing quick. Conversion to the active coenzyme happens within hours, but plasma pyridoxal 5-phosphate takes a couple of weeks to settle at a new level.
Red cell folate climbs over roughly four to eight weeks. It's a blood panel change rather than a sensation.
Markers move first. Methylmalonic acid and homocysteine start shifting within a week or two, while anything you would notice takes several weeks of daily use.
Fingernails grow around 3mm a month, so it takes roughly 8 to 12 weeks before enough new plate has grown out to judge the difference by eye.
How each ingredient usually behaves over time, from its own page on IngredientMD. General timing for the ingredient, not a measurement of this product.
What each form is, and where it fits in a formula. Measured findings carry the study that reported them.
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.
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.
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.
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.
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.
Magnesium held as a salt of malic acid, the four-carbon fruit acid that also sits in the citric acid cycle. The common di-magnesium form is roughly 15 percent magnesium by weight, dissolves in water and carries a mild tart note.
Zinc chelated to two glycine molecules through a nitrogen and an oxygen bond, the smallest amino acid available for chelation, giving a low molecular weight chelate of about 26 percent zinc by weight. It is a neutral-tasting dry powder with mild solubility and is stable across the pH range a capsule or tablet passes through.
In a six-week placebo-controlled pilot intervention in young adult women (10 per arm, 30 in total) at 60 mg zinc daily, a dose above the 40 mg tolerable upper intake level for adults, plasma zinc, described by the authors as the traditional assessment of zinc status, increased in all subjects given zinc glycinate, while no significant change was seen overall for zinc gluconate or placebo. Erythrocyte superoxide dismutase activity, used in that study as a marker of zinc-induced copper deficiency, was unchanged in all three groups over the six weeks. A 2024 narrative review of the chemical forms of zinc, written by authors employed by a supplement manufacturer, states that little information is available comparing the absorption and bioavailability of the different chemical forms. No stable-isotope absorption study in humans has measured this form.
A chelate in which one copper ion is held by two glycine molecules in a ring structure, sold as a defined amino acid mineral complex.
Manganese coordinated to two glycine molecules to form a metal-amino-acid chelate, in which the mineral is held inside an organic ring rather than as a loose ionic salt.
Trivalent chromium complexed with niacin (nicotinic acid) as the coordinating ligand, marketed as niacin-bound because nicotinic acid is a component of naturally occurring glucose tolerance factor.
Boron held within an organic complex with the amino acid glycine rather than as a plain mineral salt. The boron sits inside an amino-acid carrier.
Descriptions of the form itself, read from the cited studies. Not a comparison between products and not a statement about any individual.
It is a capsule, so the amount per serving is fixed and travels without measuring.
Where two of this brand's products carry actives the literature has read together, the pairing and its basis are below. The evidence word is the corpus row's own confidence, never a score.
