Product Benefits


Marks-Min ZMSC with B12 provides elements that support growth by aiding cell, bone, muscle, cartilage and connective tissue growth and development, as well as protein metabolism, DNA production, thyroid function and nerve myelination.


Marks-Min ZMSC with B12 provides elements that support reproduction by aiding the development of male and female reproductive organs and their functions, the process of fertilisation and also the maintenance of pregnancy.


Marks-Min ZMSC with B12 provides elements that support immune defence by aiding function of the immune system and white blood cells that help combat and resist the establishment of infections.


Vitamin B12 plays a key role for the production of energy in livestock. Energy is required for all bodily processes and it is the backbone of all production.


Marks-Min ZMSC with B12 contains zinc, manganese, selenium, copper and vitamin B12, which are required for optimal health, production and fertility. Sub-optimal trace mineral and vitamin B12 status, particularly during periods of stress, such as calving, mating and drying off, have been shown to negatively impact production, reproduction and health. Using an injectable supplement can improve trace mineral and vitamin B12 status at these critical times, promoting a healthy immune system, which is important in resisting disease, and has a positive impact on reproduction.
