Zinc
History of Ingredient
Zinc, a trace element, has been recognised for its significance in human health for over two millennia. Ancient civilisations, such as the Greeks and Egyptians, utilised zinc compounds for medicinal purposes, often in wound healing.
The discovery of zinc as a metal can be traced back to India, and by the 16th century, it was being used in Europe for brass production. It wasn’t until the 20th century that the essential role of zinc in human nutrition and metabolism was fully understood.
Scientific Make-up
Zinc is a transition metal, positioned in Group 12 of the periodic table. It possesses an atomic number of 30 and is denoted by the symbol ‘Zn’. Chemically, it is less reactive than its counterparts due to the full d-orbitals.
Biologically, zinc acts as a cofactor for over 300 enzymes, playing a crucial role in protein synthesis, DNA replication, and cell division. Its chelated form, often found in supplements, ensures better absorption in the body.
Benefits of Ingredient
Zinc is indispensable for numerous physiological functions:
1. Immune System Support: Zinc is pivotal for immune cell development and communication and plays a role in inflammatory response.
2. Metabolism: It aids in protein synthesis, DNA synthesis, and cell division.
3. Wound Healing: Zinc accelerates the healing process after injuries.
4. Sense of Taste and Smell: It is essential for the proper function of these senses.
5. Skin Health: Zinc can reduce the risk of diseases like acne and certain skin lesions.
Several studies, such as this one, have shown the importance of zinc in reducing the duration of cold symptoms.
Forms of Consumption
Zinc can be consumed in various forms:
1. Tablets and Capsules: The most common form, often combined with other vitamins and minerals.
2. Zinc Lozenges: Specifically designed to combat cold symptoms.
3. Liquid Solutions: For those who find swallowing tablets challenging.
4. Topical Creams: For skin-related issues, often combined with vitamin E.
5. Intranasal Sprays: Though less common, they are available for specific conditions.
It’s also worth noting the rise in popularity of innovative supplement delivery methods, such as gummies, which often incorporate zinc alongside other beneficial ingredients like vitamin C and magnesium.
Safety + Dosages
While zinc is essential, excessive consumption can lead to adverse effects. The recommended daily allowance (RDA) varies: 11mg for men, 8mg for women, and 3-5mg for children. Overconsumption can result in nausea, vomiting, and weakened immunity.
It’s always advised to consult with a healthcare professional before starting any supplement regimen.
