What we know
Muttoo currently shows this as Source-dependent from a desk note. That is not a certifier ruling.
What we don’t know
No external A or B source (certifier or scholarly page) is on file yet. The pack in your hand does not, by itself, name the raw material or process.
Why it matters
Doubtful until the source is known (mashbooh)
What to verify
For Galactooligosaccharides in this product: is the source plant, synthetic, or animal? If animal, which species and slaughter method?
What the sources say
A prebiotic fibre typically made from lactose. Dairy origin plus the enzyme is the pair of questions. Not the same as FOS or inulin, which are plant.
Where you will run into it
- Infant formula
- Prebiotic powders
How to check it yourself
Usually made from lactose with a microbial enzyme. Ask the dairy source and the organism.
What to ask the manufacturer
A recognised halal mark or a vegan declaration can settle this instead. If you email the brand, send one specific question:

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.
