Other Ingredients (16)

BHTPreservative

Potential carcinogen in animal studies; may affect thyroid function; restricted in some countries

Blue 2 LakeColorant

A synthetic coal-tar/petroleum-derived dye used purely for color, linked to behavioral concerns in sensitive children. The lake form adds aluminum. No health benefit — we flag all artificial colors.

TalcAnti-caking

IARC classifies cosmetic-grade talc not containing asbestos as Group 2B (possibly carcinogenic to humans); perineal talc use as Group 2A (probably carcinogenic). Johnson & Johnson voluntarily withdrew talc-based baby powder from US/Canada in 2020 and globally in 2022 after extensive litigation tied to ovarian-cancer and mesothelioma cases. The 2018 FDA contamination survey found asbestos in 9 of 52 cosmetic talc products tested. As a supplement excipient talc is a pure manufacturing convenience — no nutritional or functional benefit to the user — so the asbestos-exposure risk has no offsetting upside. Safer alternatives (silicon dioxide, microcrystalline cellulose, rice hulls) are widely available.

Titanium DioxideColorant

Banned in the EU (2022) over concerns that its ultra-fine particles may damage DNA in gut cells. Still allowed in the US. Used only for white coloring — provides no health benefit.

FD&C Red No. 40Color

Artificial azo dye; ADI-limited; associations with hyperactivity in sensitive children in some studies.

Magnesium StearateLubricant

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

Polyethylene Glycol (Coating)Coating

A polyether polymer used as a tablet coating and plasticizer

Polyvinyl AlcoholCoating

Synthetic, water-soluble polymer used as a film former and binder in immediate-release tablet coatings

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 coffee, tea and dairy
Space it a couple of hours from Green Tea Leaf Extract

On the label

As a dietary supplement, adults take one (1) tablet daily with any meal or as directed by a healthcare provider.

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