Fresh green tea leaves (Camellia sinensis) – green tea extract in bulk, wholesale and private label

Green tea extract in bulk: L-theanine capsules, extract powder and private label

Short answer: GOA Supply supplies green tea extract in two bulk forms: ready-filled capsules with green tea extract standardised to 98% L-theanine, in 20,000, 50,000 or 100,000 capsules, and green tea extract powder, a concentrated extract of green tea leaves with naturally occurring catechins and polyphenols, in 10, 50 or 100 kg. Both are available for private label. Before you buy, check what the extract is standardised to, because that decides which EU rules apply to your product.

What is green tea extract?

Green tea extract is made from the leaves of the tea plant, Camellia sinensis. The leaves are extracted with a solvent, and the extract is concentrated and dried into a powder, sometimes with a carrier. Unlike matcha, which is the whole leaf ground into powder, an extract contains selected compounds of the leaf in concentrated form. Our article on green tea extract powder vs matcha powder explains that difference in detail.

"Green tea extract" is a broad trade name. One extract can be standardised to catechins, another to L-theanine, an amino acid that occurs in tea leaves. For a buyer, the standardisation is the most important line on the specification.

What to check when you buy green tea extract in bulk

  1. Standardisation. Ask which compound the extract is standardised to and at what percentage, and how it is measured. Two products both called green tea extract can differ completely in composition.
  2. Solvent and carrier. Ask which extraction solvent was used and whether a carrier was added during drying. The carrier belongs in your ingredient list, and the solvent matters for France (see below).
  3. EGCG content. If the extract contains epigallocatechin gallate (EGCG), you need its content per gram to calculate the amount per daily portion for your label.
  4. Amount per capsule. For the capsules, confirm the fill weight and the amount of extract per capsule in the specification and the certificate of analysis (CoA) before you design the label.
  5. Contaminants. Ask which parameters the CoA covers. Regulation (EU) 2023/915 sets a maximum level of 400 µg/kg for pyrrolizidine alkaloids in food supplements containing botanical preparations, and Regulation (EC) No 396/2005 sets maximum residue levels for pesticides.
  6. Storage. Keep extract powder and capsules closed, cool, dry and away from light, and use older batches first.

EU rules for green tea extract

Which rules apply depends on what the extract contains.

  • Extracts containing EGCG: Regulation (EU) 2022/2340 lists green tea extracts containing EGCG as restricted substances. A daily portion of the food must contain less than 800 mg EGCG. The label must state the EGCG content per portion and the maximum number of portions per day, and carry warnings, including that the product should not be consumed on an empty stomach or on the same day as other products containing green tea. Aqueous extracts that, after reconstitution in beverages, have a composition comparable to traditional green tea infusions are excluded.
  • L-theanine: the EU Novel Food Catalogue lists L-theanine extracted and isolated from green tea as not novel in food supplements only. L-theanine from other sources is a novel food. Use green tea L-theanine in food supplements, not in other foods, unless you have checked the status for that use.
  • France: Compl'Alim lists the leaf of Camellia sinensis as authorised. It notes that under the French decree of 24 June 2014 only powder from ground leaves and preparations made with water, 25% (v/v) alcohol or the solvents authorised for decaffeination or removing bitter substances are accepted. Check the solvent before you declare a product in France.

Green tea extract capsules are sold as food supplements, so Directive 2002/46/EC and the national notification rules apply: no notification in the Netherlands, a notification via FOODSUP in Belgium, a declaration via Compl'Alim in France and a notification to the BVL in Germany. Health claims are only allowed if they are authorised under Regulation (EC) No 1924/2006.

Private label green tea extract

For private label, we supply the capsules ready-filled in bulk. They are filled by a contract manufacturer in the Netherlands, whose organic certificate is available on request. You add your own packaging and label. The extract powder is supplied in bulk for your own packaging, or as a raw material for your own capsules or blends. As the brand owner, you are responsible for the label, the recommended daily intake, any claims and the notifications in the countries where you sell. Our guide to starting a private label supplement brand in the EU covers the steps.

FAQ

What is the difference between your green tea extract capsules and the extract powder?
According to our product data, the capsules contain green tea extract standardised to 98% L-theanine in HPMC capsules, and the powder is a concentrated green tea leaf extract with naturally occurring catechins and polyphenols. Request both specifications to compare them for your formula.

Does Regulation (EU) 2022/2340 apply to green tea extract capsules?
It applies to green tea extracts containing EGCG. Ask for the EGCG content of the extract and calculate the amount per daily portion of your product to see which conditions and warnings apply.

Is L-theanine from green tea a novel food?
The EU Novel Food Catalogue lists L-theanine extracted from green tea as not novel in food supplements. In other foods, and from other sources, it is a novel food.

Can I sell green tea extract in France?
Yes, after a declaration via Compl'Alim. Check the extraction solvent first, because the French rules for Camellia sinensis preparations accept only certain solvents.
