Other ingredients — the bottle audit
Pharmacists do not certify a brand from the front of the tub. They read the shell, the lubricant, the carrier and the colour. Each line is a catalogue row. This is not a product certificate.
- Capsule shell. Gelatin, HPMC (hypromellose) or pullulan. Bare gelatin follows the capsule row — it is not the powder. Gelatin capsules · HPMC · Pullulan
- Glycerin / glycerol. Softgels and liquid drops. Plant or synthetic settles it; animal fat does not. The bottle rarely says which. E422 glycerol
- Magnesium stearate. The lubricant in most tablets. Vegetable or synthetic vs animal including porcine. A vegetarian capsule does not settle the powder inside. E572 magnesium stearate
- Flavourings. Natural flavour can hide an ethanol carrier. Vanilla extract is a different, disputed row. Natural flavours · Vanilla extract
- Colour. Carmine / cochineal (E120) is insect. Plant colours are a different page. Natural colour is not a plant guarantee. E120 carmine
Creatine powder is a different question from a creatine capsule. D3 wants lanolin vs lichen. Collagen wants a species.
