You're getting a wide range of essential vitamins and minerals in a single tablet, but nearly all doses sit at or near RDA levels — enough to prevent deficiency, not enough to reach the clinical ranges used in research. **Vitamin D** at 400 IU is well below the 1,000–5,000 IU range supported by current evidence, and B vitamins like **thiamine** (1.5mg) and **B6** (2mg) land far short of the 25–100mg doses found in dedicated B-complex products.
The ingredient forms are budget-tier across the board: your **zinc** comes as oxide (poorly absorbed), **magnesium** as oxide, **vitamin E** as synthetic dl-alpha-tocopheryl acetate, and **B12** as cyanocobalamin rather than the active methylcobalamin form. **Iron** at 18mg is one bright spot, landing right in the clinical range and delivered as ferrous fumarate.
If you're looking for baseline nutritional insurance to fill small dietary gaps, this does the job at a low cost per serving. But don't expect therapeutic-level support for energy, immunity, or any specific health goal — the doses and forms aren't designed for that.

Boric AcidBuffer
Borates are classified as reproductive/developmental toxicants (EU CMR Cat 1B) at meaningful exposure and are not appropriate for high oral intake; acceptable only in the trace buffer amounts typical of some formulations.
MaltodextrinBinder
Spikes blood sugar faster than table sugar (glycemic index 85–105). Research links it to gut bacteria changes that may promote intestinal inflammation (Nickerson et al. 2015). Used as a cheap filler — adds nothing beneficial.
Sodium BorateBuffer
Classified as a Substance of Very High Concern (SVHC) under EU REACH for reproductive toxicity (Category 1B — may damage fertility and the unborn child). EFSA's tolerable upper intake from total boron exposure is 10 mg/day for adults; sodium borate dosing must stay well below this. Acute oral toxicity is moderate (lethal dose ~5–20 g in adults), but the chronic-exposure reproductive endpoint is the binding constraint. Largely phased out of modern supplements and personal care in favor of safer buffers (citrate, phosphate). If a current product lists sodium borate, the inclusion warrants scrutiny — there are safer alternatives for every excipient function it provides.
Beta-Carotene (color)Color
Beta-carotene used in small amounts as a colorant/antioxidant.
BiotinFood
Vitamin B7, a water-soluble B-vitamin.
Folic AcidVitamin
Synthetic form of vitamin B9 used for fortification — supports red blood cell formation and neural tube development. Pharmacologically distinct from the natural/active form (5-methyltetrahydrofolate, methylfolate).
LycopeneAntioxidant
A red carotenoid pigment/antioxidant, typically sourced from tomato.
Magnesium OxideMineral Source
An inorganic magnesium salt used as a magnesium source or bulking mineral.
