Other Ingredients (26)
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.
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.
Magnesium StearateLubricant
A salt of stearic acid used as a lubricant in tablet and capsule production
Methylsulfonylmethane (MSM)Food
An organic sulfur compound (dimethyl sulfone) used as a dietary ingredient.
Mineral OilEmollient

Polyethylene Glycol (Coating)Coating
A polyether polymer used as a tablet coating and plasticizer

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