A Multi-Ingredient Formula for Everyday Gut Wellbeing
Digestive comfort is something people who take their gut wellbeing seriously tend to approach with more than a single ingredient. L-Glutamine Complex brings together ten ingredients in one capsule: the amino acid L-Glutamine, Butyric Acid, N-Acetyl-D-Glucosamine (NAG), Quercetin, Zinc Picolinate, and five botanicals with long histories of traditional use — Marshmallow Root, Slippery Elm Bark, Deglycyrrhised Liquorice Root, Chamomile Flower and Mastic Gum. Four capsules per day provides a 30-day course.
Why People Choose L-Glutamine Complex
✓ Ten complementary ingredients in a single daily formula
✓ Marshmallow root, slippery elm, chamomile and mastic gum have each been used in traditional wellness practice for generations
✓ Deglycyrrhised (DGL) liquorice — the form with glycyrrhizin removed for everyday use
✓ Zinc Picolinate — a well-regarded, highly bioavailable form of zinc
✓ 120 capsules, 30-day supply at four per day
✓ Manufactured in the UK to GMP Code of Practice and ISO 9001
More Than L-Glutamine Alone
Single-ingredient L-Glutamine is widely used. L-Glutamine Complex is for people who want to take a broader approach and combine the amino acid with other ingredients they already use or research separately. Rather than maintaining a row of individual bottles, this formula brings the whole approach together. Zinc Picolinate — a well-regarded, highly bioavailable form — is included alongside Quercetin and a set of botanicals with established use histories, all in one capsule.
Making It Part of Your Daily Routine
Four capsules per day is the recommended serving. Many people find it works well to split the dose across the day — two capsules in the morning and two in the evening, with water. If there is any discomfort taking capsules on an empty stomach, they can be taken alongside food. The 30-day supply fits naturally into a monthly routine, with a consistent daily dose rather than a variable one.
Traditional Botanicals with a Long History of Use
Four of the ten ingredients in this formula are plants with documented histories of use in traditional herbalism: Marshmallow Root (Althaea officinalis) has been used in European herbal tradition for centuries as a demulcent — a soothing herb associated with mucilaginous properties. Slippery Elm Bark (Ulmus rubra) is a North American tree whose inner bark has been used in Indigenous and later settler herbal traditions. Liquorice Root (Glycyrrhiza glabra), here in its deglycyrrhised (DGL) form with glycyrrhizin removed, has wide use across Asian, European and Middle Eastern traditional systems. Chamomile Flower (Matricaria recutita) is one of the most widely consumed botanical infusions in the world and has a long association with digestive wellness in traditional practice. Mastic Gum (Chios Mastiha, from Pistacia lentiscus) is a resin with origins in the eastern Mediterranean and a history of use in Greece and across the region. These are included for their traditional provenance and as studied ingredients in contemporary nutritional research.
Inside the Formula
L-Glutamine — the most abundant free amino acid in human muscle tissue and plasma, included here as the foundational ingredient of the complex.
Butyric Acid — a short-chain fatty acid naturally produced in the gut through fermentation of dietary fibre by the gut microbiome.
N-Acetyl-D-Glucosamine (NAG) — an acetylated form of glucosamine, a naturally occurring compound found in connective tissue. Derived from crustaceans; not suitable for vegetarians or vegans.
Quercetin (from Sophora japonica) — a flavonoid found naturally in many fruits and vegetables, extracted from Sophora japonica and widely referenced in nutritional research as a natural polyphenol.
Zinc (Picolinate) — provided in the picolinate form, a well-regarded bioavailable form of zinc used in nutritional supplements.
Marshmallow Root Extract (4:1) · Slippery Elm Bark · Deglycyrrhised Liquorice Root (10:1) · Chamomile Flower Extract (5:1) · Mastic Gum (Chios Mastiha) — five traditional botanicals with documented histories of use in herbal practice, included for their traditional provenance and standing as widely used wellness plants.

Frequently Asked Questions
How many capsules should I take per day?
Adults take four capsules per day with water. Dividing the dose across two or three sittings is often preferred. If there is any discomfort on an empty stomach, take with food.
Is this product suitable for vegetarians or vegans?
No. The formula contains N-Acetyl-D-Glucosamine (NAG) derived from crustaceans. It is not suitable for vegetarians or vegans. If you have shellfish allergies, consult your healthcare practitioner before use.
Why is DGL liquorice used rather than standard liquorice?
Deglycyrrhised (DGL) liquorice has had the compound glycyrrhizin removed, which is associated with effects on blood pressure and cortisol at higher doses. The DGL form is more appropriate for everyday use in a daily supplement.
How long will a bottle last?
At the recommended four capsules per day, 120 capsules provides a 30-day supply.
Where is this product made?
Manufactured in the United Kingdom to GMP Code of Practice and ISO 9001.
