FAQs
Frequently asked questions
You can support normal immune function by maintaining a healthy lifestyle
that includes a varied, balanced diet, regular exercise, sufficient sleep and effective stress management. Eating a variety of fruit and vegetables provides important vitamins and minerals, while fibre-rich foods can support a healthy gut microbiome. Citrus fruits, green vegetables, garlic and ginger can all form part of a balanced diet. For additional nutritional support, vitamin C, vitamin D and zinc contribute to the normal function of the immune system. Supplements can complement a healthy diet and lifestyle, but they should not replace them.
Vitamin C, vitamin D and zinc are key nutrients that contribute to the normal function of the immune system. If your diet does not provide enough of these nutrients, a suitable supplement can help you maintain your daily intake. Nature’s Best offers several immune-support supplements including Vitamin C Time Release 1000mg, Vitamin D3 1000iu, Zinc 15mg and Berryguard Immunity Gummies.
Yes. Vitamin D contributes to the normal function of the immune system. Vitamin D is therefore an important nutrient to consider when looking for everyday immune support. Nature’s Best Vitamin D3 400iu provides 10µg per tiny tablet, the level recommended by The Department of Health
. Higher levels of Vitamin D3 are available -1000iu (25µg) and 2000iu (50µg) both in a convenient once-daily capsule.
Vitamin C, vitamin D and zinc are among the most relevant vitamins and minerals for normal immune function. Vitamin C and zinc contribute to the normal function of the immune system, while vitamin D also contributes to normal immune function. Nature’s Best’s Berryguard Immunity Gummies combine vitamin C and zinc with elderberry extract, while Beta Glucans 250mg combines beta glucans with vitamins C and D3, zinc and selenium. The right supplement depends on your individual diet, nutritional needs and the nutrients you are looking to supplement.
