Why brands use L-Theanine
L-Theanine is an amino acid commonly considered for energy, recovery and cognitive ranges, sitting in the amino acids family. On DAT Supply briefs the positioning is set by the brand brief and reviewed against the target market’s claim rules — we do not pre-position an active for any single benefit. Editorial framing uses only EU 432/2012- or DSHEA-compatible wording — we never promote unauthorised claims, even when the active has consumer-side momentum. Format-wise we have considered L-Theanine for gummies, strip, jelly and pet soft chew; the per-format formulation notes below describe the live constraints (taste, payload, stability, packaging) we tune in the formulation pass. Sourcing form (extract ratio for botanicals, salt or chelate form for minerals, free-form vs ester for amino acids) is reviewed against the brief, with documentation matched to the target market’s import rules. Inclusion rate and claim wording are reviewed per project — no two briefs land on the same combination, and we don’t publish off-the-shelf doses.

- Matrix choice (pectin vs gelatin) and its effect on ingredient stability — confirmed per project.
- Per-gummy dose and serving count needed to hit the label claim — confirmed per project.
Oral strips
- Per-strip dose ceiling — actives must fit a 30–60 mg film payload — confirmed per project.
- Sensory and dissolution constraints (mouth-feel, grit, bitterness) — confirmed per project.
- Film compatibility with the polymer base (pullulan / HPMC) — confirmed per project.
Functional jellies
- Set strength and matrix stability against the active load — confirmed per project.

Pet soft chews
- Species suitability — dog vs cat tolerance reviewed by the formulation team — confirmed per project.
- Palatability profile and the carrier base (meat, plant, dairy) — confirmed per project.
- No veterinary treatment implication — soft chews are a supplement format, not a therapy — confirmed per project.
Claim framework
As a free-form amino acid L-Theanine is positioned with EU 432/2012-compatible wording where an authorised claim exists; otherwise editorial wording stays neutral and structural, focused on the active’s role in the body rather than a benefit. UK rules track EU wording. For the US market, DSHEA structure-function rules apply with the FDA disclosure. Inclusion rate is reviewed against the target positioning — sports, recovery, sleep or cognitive — and confirmed per project. Where an amino acid stack is on the brief, the per-active balance and the combined per-serving load are reviewed against the chosen format’s payload window.
Typical anchor: mg per serving — confirmed per project.
L-Theanine is measured by weight (mg) per serving on DAT Supply briefs. The working anchor — the inclusion rate against which target-market claim wording is reviewed — is set during the formulation pass for each project rather than published as a fixed number on the public page. Final per-serving load depends on the chosen format (gummy payload window, capsule fill weight, softgel oil load, sachet or powder scoop size, oral-liquid bottle geometry) and the claim wording the brand needs to support against the target market. Sourcing form (extract ratio, standardised marker, micronised vs granular, salt or chelate form) is reviewed in the same pass. Country-level upper limits (France, Italy, Belgium for the EU; California Prop 65 for the US) are checked before any inclusion rate is finalised. Dose is confirmed per project — we don’t publish off-the-shelf dose tables for any active in the catalogue.
