Zinc

Why do we need zinc?

Zinc plays critical roles in immune function, protein synthesis, wound healing, DNA synthesis, and cell division. Zinc is critical for the development and function of immune cells and it’s important for the maintenance of healthy hair, skin and nails.

Symptoms of a zinc deficiency include growth and development impairment (children), chronic diarrhoea, skin rashes, slow wound healing, weak immunity response and behavioural issues (1,2).

Food sources of vitamin Zinc.

Zinc is found primarily in animal products such as beef, poultry, and shellfish. Lower levels can be found in whole grains, legumes, nuts and seeds.

What is the Nutrient Reference Value of Zinc?

10 mg/day for adults. The upper limit for zinc is 40mg/day (3).

For who do we recommend a supplement?

People who follow a vegetarian or vegan diet, consume alcohol, or have been diagnosed with certain diseases such as sickle cell anaemia or gastrointestinal diseases may require a higher intake than healthy people or those who consume meat.

Furthermore, zinc supplementation is an effective method for maintaining a healthy immune function and it can help in reducing the duration and severity of the common cold (4). It may also help to lower the susceptibility to pneumonia and other infections and help clear acne (2, 5, 6).

Studies have shown that symptoms of depression and low mood may be improved by zinc supplementation for some people (7, 8).

Why choose supplements from Fresh Fitness Food?

Zinc absorption from zinc citrate is one of the highest. Furthermore, zinc citrate has better sensory properties and doesn’t give a bitter and metallic aftertaste as with other forms (9).

When it comes to our health, the food we put in our bodies can have a significant impact in many ways. It affects our mood, energy levels, stress, physical activity and everything in between. The right nutrition can help us to feel better, every day. At Fresh Fitness Food we believe in a food-first approach as food provides you with so much more than just nutrients. Many of us should be able to get most nutrients from a healthy and balanced diet, however, there are some caveats and exceptions where food supplements can assist to fill up the gaps.

If you are unsure or have any questions about food supplements, you can book in for a call with one of our all-knowing nutritionists here (link: https://meetings.hubspot.com/fffcall/supplements-consultation).
