Capsule structure of a nutritional supplement composition

Abstract

This novel invention relates to a capsule structure for a nutritional supplement composition, comprising a capsule shell and a nutritional composition disposed within the capsule shell, the nutritional composition incorporating a phospholipid structure. The phospholipid structure has a core region encapsulated by a phospholipid bilayer membrane and forms a layered distribution structure of aqueous and lipid phase regions, such that water-soluble and lipid-soluble nutrients are respectively disposed in different phase regions. The water-soluble components may include extracts of *Gnaphalium affine* and vitamin C, while the fat-soluble components may include lutein, zeaxanthin, and vitamin E. Through the interfacial separation effect formed by the phospholipid bilayer membrane, different soluble nutrients can coexist stably in the same capsule, reducing the interaction between components and improving storage stability.

Claims

1. A capsule structure for a nutritional supplement composition, comprising: a capsule shell (1); and a nutritional composition (20) disposed within the capsule shell (1); wherein, The nutritional composition (20) incorporates a phospholipid structure (2), which includes: a core region (21); and an outer phospholipid bilayer membrane (22) covering the core region (21), forming a spherical carrier structure (23); the phospholipid bilayer membrane (22) is composed of phospholipid molecules arranged to form an aqueous phase region (24) and a lipid phase region (25), so that water-soluble nutrients (26) and lipid-soluble nutrients (27) are respectively disposed in different phase regions, wherein the aqueous phase region (24) can accommodate water-soluble nutrients (26).

2. The capsule structure as described in claim 1, wherein the water-soluble nutrient (26) is disposed in the core region (21) or the aqueous phase region (24).

3. The capsule structure as claimed in claim 1, wherein the fat-soluble nutrient (27) is disposed in the interfacial region or lipid phase region (25) of the phospholipid bilayer membrane (22).

4. The capsule structure as claimed in claim 1, wherein the nutritional composition (20) comprises sphagnum moss extract (28), vitamin C (29), lutein (30), zeaxanthin (31), bilberry extract (32) and vitamin E (33).

5. The capsule structure as described in claim 4, wherein lutein (30) and zeaxanthin (31) are co-located in the lipid phase region.

6. The capsule structure as described in claim 4, wherein the bilberry extract (32) is disposed in the aqueous phase region.

7. The capsule structure as described in claim 4, wherein the extract (28) of *Gnaphalium affine* is disposed in the core region (21) or the aqueous phase region (24).

8. The capsule structure as claimed in claim 1, wherein the phospholipid structure (2) is a spherical carrier structure (23) covered by a phospholipid bilayer.

9. The capsule structure as claimed in claim 1, wherein the capsule shell (1) is a plant-based hydroxypropyl methylcellulose capsule.

10. The capsule structure as claimed in claim 1, wherein the water-soluble nutrient (26) is disposed in the core region (21) or the aqueous phase region (24), and the fat-soluble nutrient (27) is disposed in the lipid phase region (25) or the interface region of the phospholipid bilayer membrane (22).
