Named ingredient
Is Phosphatidylserine halal?
Health Canada describes most food-grade phosphatidylserine as soy lecithin reacted with serine using phospholipase D, and notes that published toxicity studies used bovine or fish PS. The soy route is not the bovine route. A 2011 IFANCA mark on one branded ingredient is a SKU, not a class ruling. Stays source-dependent.
Route decides. Soy enzymatic, bovine cortex, or fish. Not a class ruling.
What we know
Named sources are on this page. Classification: Source-dependent.
What we don’t know
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 Phosphatidylserine in this product: is the source plant, synthetic, or animal? If animal, which species and slaughter method?
The detail
The catalogue previously had only a desk stub. The Health Canada safety summary is an identity of manufacturing routes, not a fatwa. Bovine-cortex PS is a different source question from soy enzymatic PS. Do not upgrade either route to verified-halal from this page.
What the sources say
Most commercially available phosphatidylserine products for food applications are derived from soy through an enzymatic reaction catalyzed by phospholipase D (PLD) with lecithin and serine as starting materials.
Phosphatidylserine on a label is usually from soy lecithin, sometimes from bovine cortex historically. The source decides.
Where you will run into it
- Nootropic capsules
- Sports recovery
- Senior memory blends
How to check it yourself
Ask: soy or bovine? Then ask the capsule. A Crescent-M / IFANCA mark on that SKU is product evidence.
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:
For Phosphatidylserine in this product: is the source plant, synthetic, or animal? If animal, which species and slaughter method?
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.
