Collagen formation support; Antioxidant support; Vascular and connective tissue support
Adults with low intakes of collagen-building nutrients from diet and those seeking daily antioxidant support for an active lifestyle.
Take 2 to 4 tablets daily with meals; dividing doses across meals may improve comfort and vitamin C absorption.
Suitable for vegetarians. Contains no yeast, dairy, egg, gluten, soy or wheat. Contains no sugar, salt, preservatives, or artificial colour, flavour or fragrance.
Lysine is an essential amino acid used for protein building and is a precursor for carnitine, supporting collagen formation through cross-linking processes.
Caution: May interact with high-dose calcium or iron timing due to amino acid competition for absorption; take as directed with meals.
Proline is a key amino acid incorporated into collagen triple helices and is converted to hydroxyproline during collagen maturation.
Caution: High intakes of single amino acids may cause mild digestive discomfort in some people; take with food and adequate water.
Vitamin C acts as a cofactor for prolyl and lysyl hydroxylase enzymes that stabilise collagen structure and also functions as an antioxidant.
Caution: High doses may cause gastrointestinal upset in sensitive individuals; split doses with meals to improve tolerance.
Rich in proanthocyanidins that help neutralise free radicals and support vascular function by interacting with endothelial signalling.
Caution: May have mild blood-thinning effects; use caution alongside anticoagulant habits or supplements.
Contains flavonoids and oligomeric procyanidins that may support healthy blood vessel tone and antioxidant defences.
Caution: May influence blood pressure responses; monitor how you feel if you are sensitive to circulatory-affecting botanicals.
Lysine and proline provide the amino acid building blocks needed for collagen, while vitamin C drives the hydroxylation steps that stabilise collagen fibres. Grape seed and hawthorn extracts add antioxidant support that helps protect collagen-rich tissues from oxidative stress. Together they cover structural formation and protection pathways.
Label Warning: If you are pregnant, may become pregnant, or breastfeeding, consult a healthcare professional before use. Natural plant variations may affect tablet colour.
Who should be cautious: People taking calcium, magnesium, or high-dose vitamin C alongside certain antibiotics or thyroid medications may need to separate dosing to avoid reduced absorption. Those with kidney concerns or a history of kidney stones may wish to discuss high-dose vitamin C with a healthcare professional. People on heart or blood pressure medicines may wish to review hawthorn and grape seed extract use with a clinician. If combining with medications that may interact with calcium, magnesium, or high-dose vitamin C, it is recommended to consult a healthcare provider first.
Storage: Keep out of the reach of children.

L-Proline is a key component in collagen production, which may support joint and skin health. Combining these can enhance collagen synthesis for better joint flexibility and skin elasticity.

L-Lysine is one of 9 essential amino acids that cannot be made in the body. It is the basic raw material for carnitine synthesis. L-Proline can be made in the body, but low protein/ vegetarian diets may not always promote optimal L-proline production. L-Lysine and L-proline amino acids are the precursors of hydroxylysine (HL) and hydroxyproline (HP), two constituents of collagen. Collagen is an essential component of arterial linings. Vitamin C, a strong antioxidant, is also essential for the production of collagen. Hawthorn berry and grape seed extract are potent natural antioxidants due to their high levels of proanthocyanidins. These proanthocyanidin esters are excellent free radical scavengers.
2 to 4 tablets daily with meals.
