Hair health is closely tied to nutritional status, and certain deficiencies such as low biotin and low iron are commonly associated with changes in hair condition.
The Hair Strength Bundle combines Biotin, Marine Collagen Complex, and Iron in a single, convenient package.
Together, they address key nutritional support for hair, skin, and the structural proteins hair is made from.
Provides 10,000µg of biotin (vitamin B7) per daily tablet.

Hair, skin, and nail support -
Biotin contributes to the maintenance of normal hair and skin. It supports keratin
production, the structural protein that forms hair strands and nails, and helps maintain
the fatty acid synthesis needed for healthy skin.
-
Supporting normal metabolism
-
Biotin also contributes to normal macronutrient metabolism, helping the body convert
carbohydrates, fats, and proteins into usable energy. This metabolic role is relevant to
the health of actively growing cells, including hair follicles.

or pharmacist before use.
Marine Collagen Complex
60 capsules
Hydrolysed marine collagen peptides with vitamin C.

Vitamin C and collagen formation
-
Vitamin C contributes to collagen formation for the normal function of skin, bones and
cartilage. Collagen is the structural protein in hair follicles and the surrounding
skin. Vitamin C also contributes to immune system function.
-
Structural protein support -
Marine collagen provides hydrolysed type I collagen peptides, the primary structural
protein in skin, hair, and nails. These are hydrolysed for absorption and used as
building blocks for the body's own protein synthesis.
Provides 14.7mg elemental iron as ferrous fumarate, a highly bioavailable ferrous
salt.

-
Normal haematopoiesis and hair health -
Iron contributes to normal formation of red blood cells and haemoglobin, and supports
immune system function. Iron is also known to contribute to the metabolism of various
nutrients. Iron deficiency is one of the most commonly cited nutritional factors
associated with hair concerns in women, and this supplement is particularly relevant for
women of childbearing age.
-
Addressing a known shortfall -
Low iron status is among the most common nutritional deficiencies in women in the UK.
The non-haem iron in plant foods is absorbed less efficiently than haem iron from meat,
making supplementation particularly relevant for those following plant-based diets.
Biotin supports keratin production, the structural protein that hair strands are formed from, as well as the fatty acid synthesis that keeps the scalp and surrounding skin in good condition.
Iron supports red blood cell formation and oxygen transport, which is relevant for the health of actively growing hair follicles.
Vitamin C, found in the Marine Collagen Complex, is well established as a compound that supports non-haem iron absorption, and it also contributes to collagen formation. Together, these three supplements address key nutritional pillars associated with hair health.
