Zinc is an essential mineral vital for numerous bodily functions‚ including immune function‚ wound healing‚ DNA synthesis‚ and cell growth. Many New Zealanders consider supplementation to ensure adequate intake‚ particularly during winter months or when experiencing dietary restrictions. This article provides a detailed overview of zinc supplements available at Chemist Warehouse New Zealand‚ covering types‚ benefits‚ dosage‚ potential side effects‚ and considerations when choosing a product.
Why Consider Zinc Supplements?
While a balanced diet typically provides sufficient zinc‚ certain factors can increase your risk of deficiency. These include:
- Dietary Restrictions: Vegetarians and vegans may have lower zinc absorption due to phytates in plant-based foods.
- Age: Zinc absorption tends to decrease with age.
- Pregnancy & Breastfeeding: Increased zinc requirements during these periods.
- Chronic Illnesses: Conditions like Crohn’s disease‚ ulcerative colitis‚ and diabetes can impair zinc absorption.
- Alcohol Consumption: Excessive alcohol intake can interfere with zinc absorption and increase excretion.
Symptoms of zinc deficiency can include impaired immune function (frequent colds)‚ loss of appetite‚ slow wound healing‚ hair loss‚ and skin problems. However‚ it’s crucial to consult a healthcare professional before self-treating with supplements.
