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.
Orange OilFlavor
Essential oil from sweet orange peel used as a natural flavoring agent. Primary component is d-limonene (~90%).
Glyceryl StearateEmulsifier
A glycerin-and-stearic-acid ester used as an emulsifier and skin-conditioning agent
Capsule ShellCapsule
Generic capsule shell where the label does not specify the material. Common materials are hypromellose (HPMC) for vegetarian capsules and gelatin for traditional capsules — both are GRAS-listed and safe. Fish gelatin and pullulan variants also exist.
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 D and E in it absorb poorly without one.
With a meal containing fat
Space it a couple of hours from Iron and Calcium
