Build your body’s defenses for flu season by using natural supplements recommended by Rosemary Barclay of Old Lyme CT.

When the holiday season is in full swing, the last thing you need is a cold. Keeping up your regular healthy habits become a challenge but may not be enough to stay healthy this winter. While getting plenty of sleep and exercise will help your immune system stay on track, Rosemary Barclay of Old Lyme CT believes there are additional supplements you should add to your diet.


Sipping green or herbal teas will not only keep you warm this winter but will also give you a nice boost of antioxidants. Rosemary Barclay specifically recommends turmeric and ginger teas for soothing the throat and strengthening the immune system. For added sweetness, consider stirring in some honey. Tea contains flavonoids which are potent antioxidants that protect against free radical damage from chemicals. Recent studies have also shown that tea also produces amino acids called L -Theanine that aid in the fight against infection. 


Natural elderberry extracts have been shown to provide antiviral and pro-immunity effects that support the immune system. There are many products available at natural health food stores, but consumers should be on the lookout for added sugars. Rosemary Barclay of Old Lyme, CT, notes that Elderberry is naturally sweet on its own. Consider making extract at home by simmering dried elderberries in water.

Vitamin D

Those who struggle with respiratory issues may want to ensure adequate Vitamin D blood levels and supplement accordingly. Studies have shown that Vitamin D can help prevent acute respiratory infections. Rosemary Barclay of Old Lyme CT notes that Vitamin D pairs well with vitamin K in the body. Consider taking a supplement that has both for an added immune boost.

Pre and Probiotics

Most of the immune system in influenced by the health of the digestive tract. Absorptive function of foods and supplements are influenced by the state of the gut . Rosemary Batclay of Old Lyme CT recommends using both probiotics and probiotics to boost immune health. Probiotics are live bacteria that populate the gut and protect the gut from problematic infections. Probiotics are a food substrate for good bacteria that makes them mutually in the gut. A combination of these help fight off urinary, respiratory and intestinal  tract infections 


Rosemary Barclay of Old Lyme, CT, stresses the importance of choosing natural and organic products that have been manufactured correctly. Some cheap products may not provide the benefits they claim or may have added ingredients that are harmful to your health. Always check with a certified nutrition specialist
