If you're over 50, this single daily tablet works as broad nutritional insurance — it covers around 30 vitamins and minerals at roughly Daily Value amounts to fill everyday dietary gaps, not to push any one nutrient to a therapeutic level. Two choices fit the mature population well: it leaves out iron, which most adults over 50 no longer need and can build up to excess, and it gives you 125mcg of **Vitamin B12**, which matters because your ability to absorb B12 from food declines with age.

For the bone and immune support this formula leans toward, you're getting maintenance-level coverage: 500 IU vitamin D, 220mg calcium, 11mg zinc, and 90mg vitamin C — enough to prevent shortfalls, but each sits at or near the RDA rather than the higher amounts used in clinical research. The lutein and lycopene are present only in trace amounts (250mcg lutein versus the 10mg used in eye-health studies), so they won't do much for you on their own. Several minerals also use oxide forms, like magnesium and zinc oxide, which your body absorbs less efficiently.

The clearest gap is vitamin D. At 500 IU, you're below the 600 IU RDA and at half the 1,000 IU floor of clinical dosing — and for bone health after 50, that's exactly where demand runs highest. Treat this as a baseline against dietary gaps, and add a dedicated vitamin D supplement if bone support is your real goal.

Other Ingredients (39)

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.

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.

Magnesium StearateLubricant

A salt of stearic acid used as a lubricant in tablet and capsule production

How to Take It

Take it anytime

No evidence a formula this broad works better at any particular hour. Take it with a meal containing fat — the vitamins A, D, E and K in it absorb poorly without one.

With a meal containing fat
Keep it away from high-oxalate foods like spinach
Space it a couple of hours from Iron

On the label

Suggested use: Take one (1) tablet daily, preferably with a meal.

General guidance based on the ingredients, not a substitute for the label or your doctor.
