“No brainer”, immune-supporting supplements

There are four areas of our lives that are fundamental to overall good health…

1. Diet

2. Exercise

3. Sleep

4. Handling stress

So, I’m sure it’s not a surprise to you that the food you eat every day, the exercise you take, the quality of your sleep and how well you handle your stress are the best ways to support a robust immune response. 

In this short blog, I’ll start the ball rolling to help you. Here are four key nutrients you must get sufficient quantities of, if you want to support a healthy immune response.

Vitamin C

There isn’t a cold remedy on the supermarket shelves that doesn’t have vitamin C in it – we all know it’s important for immune health. And when we are ill, our bodies need considerably more. Studies have shown that people taking 2g (2,000mg) of vitamin C during a cold, shortened the duration of the cold by 21%. Vitamin C also supports better anti-viral responses and helps if you have allergies and asthma. I take 1,000mg each day and increase it if I feel like I’m coming down with something.

Vitamin D

Vitamin D deficiency is widespread in the UK. The lower your level the greater your risk of catching all types of infections. Vitamin D supplementation is safe and protects against upper respiratory tract infections. Vitamin D also helps with allergies and asthma too. Taking 1,000-2,000 IU per day will help you achieve a goal of 70nmol/l. Under the tongue drops are well absorbed. (You’ll need to do an at-home, finger-prick blood test to know your levels).

Zinc

Zinc is a crucial trace mineral for immune health. Just small deficiencies can increase the risk of infections and pneumonia. Zinc is both anti-viral and anti-bacterial. A meta-analysis (the best type of study there is) showed that sucking zinc lozenges helped people with the common cold recover 3 times faster than those with none. 10-25mg is a suggested daily dose if you are low.

Selenium

Selenium is one of our master antioxidants. Low selenium has been shown to increase susceptibility to viral infections. Supplements of 100-200mcg per day are safe and inexpensive.

Probiotics

Our gut microbiome plays a critical role in regulating our immune system. Lactobacillus and Bifidobacter species are key probiotics you want. Look for 50 billion CFU’s. Don’t forget that the more antibiotics you have had and the older you are, the lower will be your numbers of these beneficial microorganisms and the more you’ll need to support your microbiome.

For very well researched, effective immune support, combine the synergistic vitamins C and D, zinc, selenium and probiotics each day.

To your best health,

Dawn 🙂
