Fighting Your Vitamin D-Mons with BetterYou

Fight Your Vitamin D-Mons

With winter well on the way, the coughs, headaches and constant tiredness you take for granted may be a symptom of something more serious than just sunlight withdrawal.

So BetterYou, the vitamin oral spray experts, are on hand to explain the importance of vitamin D.

Why is vitamin D so important?

Vitamin D is vital for the development of healthy bones, boosting immunity and helping to fight off colds and flu. Having adequate levels of vitamin D has also been linked to helping prevent cardiovascular diseases, IBS and other auto-immune diseases.

How do I get vitamin D?

We make vitamin D from sunlight, but sadly even during the summer months we miss out on the vital vitamin as we layer on the SPF or head for the shade. So, along with our increasingly indoor lifestyles, by the time it gets to winter we have no chance of maintaining our levels from the sun alone.

Another way of getting vitamin D is through our diet, but unless you plan on eating at least seven eggs or twelve packets of cheese everyday, it is extremely difficult to get the recommended daily allowance, even with a healthy diet.

The easiest way to get the right amount of vitamin D is therefore to use a supplement.

Are you at risk?

The Government now recommends that everyone should take a vitamin D supplement throughout the autumn and winter months, with ‘at risk’ groups being advised to supplement all year round, which include:

  • Pregnant and breastfeeding women
  • Infants and children
  • People over the age of 65
  • People with darker skin
  • Those who have low or no sun exposure

What are the signs?

It’s not surprising that around one in five adults and around one in six children (that’s more than 10 million of us!) have low vitamin D levels. So how do you know if you are lacking in the sunshine vitamin?

Tiredness & fatigue, bone & teeth problems, seasonal affective disorder (SAD), coughs & colds, and low mood are all symptoms of vitamin D deficiency that are often overlooked.

If you suffer from any of these on a regular basis it could mean you are lacking in vitamin D and now is the time to start fighting off those D-mons!

Sunshine in a spray

Many of us don’t like taking pills – we can find them difficult to swallow and are restricted to when we can take them.

But now, supplementing the sunshine vitamin has never been so simple. BetterYou has created a range of vitamin D oral sprays suitable for the whole family which deliver the nutrient directly into the bloodstream, via the soft tissue of our inner cheeks, which trials have shown is 2.5 times more effective than taking vitamin capsules.

Taking a spray rather than tablets or capsules also means that the vitamin is not lost through the processes of the digestive system, and is easy to use on the go with no need for food or water.

Take a look at how an oral spray can help boost your levels.

Beat the winter bugs with beneficial bacteria

As the weather worsens and the season of colds and coughs approaches, our thoughts turn towards ways in which we can support our immune systems to help keep us fighting fit throughout the winter.

A current theory in medicine, known as the ‘Hygiene Hypothesis’, states that our obsession with household cleaners and overzealous hand washing with anti-bacterial agents may be to blame for a rise in infections, as well as conditions such as asthma.

Our immune system is designed to fight infection from bacteria, viruses and parasites as well as recognise foreign substances as allergens. As our bodies no longer need to fight germs as much as they did in the past, we no longer have to elicit an immune response. The theory indicates that bacteria can in fact be helpful for supporting our immune systems.

So, how can we use bacteria to help boost our immunity? Health experts suggest we should allow children to be children by letting them play outside in mud and with their friends, and worrying less about them coming into contact with dirt and germs. There is also an increasing body of evidence supporting the use of probiotics (beneficial bacteria) for immune support. Our digestive tract functions as a barrier against potentially harmful bacteria and food. It is known that supplementing with probiotics can help mediate our immune response, reducing inflammation and protecting us against exposure to potentially harmful bugs.

Back to School: Immune-boosting tips for kids

The start of the new school year is upon us, and this can cause worry for some parents whose children seem particularly vulnerable to illness. Coughs, colds, ear and chest infections are commonplace in schools, with the average child catching between 8 and 12 colds or flu viruses each year. This is not surprising when we consider that the school environment is the perfect breeding ground for infection – up to 90% of children with a cold are carrying the virus on their hands, and germs can survive up to three days on surfaces.

Fortunately there are some simple measures that can help support your child’s immune system, helping to lessen the duration of an infection or even avoid illness altogether.

A good night’s sleep
Children need more sleep than adults, with primary school children needing at least 9 hours each night. Any less than this can compromise the immune system. Sleep deprived children have lower levels of germ-fighting T-cells, leaving them vulnerable to infection (1). Tips to improve sleep include keeping a regular bedtime routine, ensuring that televisions are kept out of the bedroom and reducing sources of caffeine such as chocolate and sodas.

Immune-boosting antioxidants
Another way to help support your child’s health is to ensure that his or her diet provides plenty of immune-boosting antioxidants. Antioxidants such as Vitamin C boost production of interferon, helping to prevent infection from taking hold (2). Vitamin E and carotenoids help to increase production of natural killer cells, B cells and T cells, increasing antibodies against specific germs (3).

Fruit-Bowl
Kiwi fruit and strawberries can provide a welcome vitamin C boost.

Finally, nutrients called bioflavonoids actually work to block cell receptors so that germs cannot get access to cells. Present in whole foods such as fruit, vegetables and grains, flavonoids have been shown to exert both anti-inflammatory and anti-viral activity (4). Flavonoids are not easily absorbed from foods we eat. For the best sources of well-absorbed flavonoids, make sure your child eats plenty of blue and purple fruits such as blueberries, raspberries, blackberries, cherries and red grapes.

If infection has already taken hold, then steps to reduce the length of an infection can be helpful. During an active infection, the body’s requirement for Vitamin C is increased dramatically. A fruit salad made with oranges, kiwi fruit and strawberries can provide a welcome vitamin C boost. During an active infection, taking a vitamin C supplement 3-4 times daily can also be a helpful measure to speed up recovery.

Protective probiotics
Probiotic supplementation offers a further protective measure for children who suffer with repeated infections. Probiotics reduce the risk of allergies, tummy upsets and diarrhoea, and have recently been found to prevent the common cold (5). They give the immune system a boost by increasing natural killer cell activity and phagocytosis, both important mechanisms for protecting against infection. In children in particular, probiotics work to ramp up levels of mucosal immunoglobulin A, the first line of defence against harmful pathogens that enter the body (6).

Probiotic supplements designed especially for children offer a safe way to support your child’s immune system. Adding some probiotic yoghurt to fruit salad or breakfast muesli can help keep your child’s levels of immune-boosting bacteria topped up.

While children can’t be shielded from every bug in the classroom, these simple measures can help ensure that your child building blocks of a strong immune system and feels fit for the new school year.

Natural Immune Support for Children

Children frequently pick up and pass on common bacterial and viral infections, often through interaction with others at school which can manifest into sore throats, colds, flu, sinusitis and more. Unfortunately large numbers of these children are prescribed antibiotics repeatedly. With the current concern over antibiotic resistance, it is natural to want to avoid having your child take antibiotics if possible.

There are a number of natural ways to reduce the risk of your children picking up illnesses. The very best insurance to help prevent you and your children getting ill is to support the immune system through diet, nutrients and lifestyle.

Here are 5 ways to boost children’s immunity naturally:

1. Wash hands but don’t be a germaphobe: Good hygiene at school and at home is important to help reduce the spread of germs. Washing hands is particularly easy and effective. However, extreme hygiene practices may have a negative effect on your child’s maturing immunity.

2. Eat foods packed with immune-boosting nutrients: Serve nutrient-dense foods to help boost your children’s immunity. A few nutrients can be essential to supporting a balanced immune system. Vitamin C can be found not only in citrus fruits, but also in broccoli, kale, green beans, berries, cantaloupe, strawberries, melons and zinc, which supports immune cell function. Foods such as pumpkin seeds, sesame seeds and seafood are all rich in zinc. Probiotic foods such as natural organic yogurt balance gut flora and are essential to a well functioning immune system.

3. Reduce refined carbohydrates and sugary foods: Refined carbohydrates like pasta, bread, biscuits and cakes and sugary foods like soda and candy can seriously tax the immune system. They feed bacterial growth and contribute to inflammation, which depletes and exhausts immune function.

4. Exercise: Research has shown that moderate exercise improves immune function for all ages. Turning off the TV, limiting the video games and getting the kids outdoors are great ways to boost children’s immunity naturally.

5. Try natural immune support nutrients and supplements: Bee Propolis is an immune boosting plant-based nutrient that is safe and effective for children. This resin is collected by bees, from tree and plant buds and has natural antibiotic, antiviral and antibacterial properties. Olive leaf extract and black elderberry are also full of antimicrobial nutrients and are also safe for all ages. Bee Prepared Immune Support Daily Defence combines these ingredients and other equally beneficial nutrients which support immune health. Capsules may be swallowed or broken open and put into juices, smoothies or yogurt.

A practical, delicious and child-friendly way to include a few of these recommendations into your daily routine is with an immune boosting smoothie.

Immunity Smoothie Ingredients:

  • 1 apple, cored, peeled and sliced
  • 1 orange, peeled and seeded
  • 1/2 cup filtered water or organic apple juice
  • 1/2 cup natural yogurt
  • 2 tsp manuka honey
  • 1 tbsp pumpkin seed butter *optional
  • 1 (2-inch) piece of fresh ginger root, peeled
  • 1 capsule Bee Prepared Daily Defence (open capsule and use the powder)

Combine all of these ingredients in a blender, serve and enjoy!

Probiotics – What are they and do you need them?

Probiotics, or ‘friendly bacteria’, are live microorganisms, which when consumed in adequate amounts, are thought to confer health benefits on the human body. Taking a daily probiotic supplement could not only help with your digestion, but could also spark off other feel-good factors, such as good skin health, immunity and wellbeing.

Digestion
Probiotics are key to the digestive system. They help the body to produce digestive enzymes (such as lactase) which breakdown certain food substances (in this case, lactose, found in dairy products.) This is why topping up your levels of probiotics on a daily basis can help with food intolerances.

Probiotics support the digestive system, and various research has shown that these microorganisms can help to encourage bowel regularity, and discourage digestive disorders or conditions such as diarrhoea (1,2), bloating (3) , or constipation(4,5).

High Quality Probiotic
A High Quality Probiotic such as OptiBac For Daily Wellbeing EXTRA Strength can help line the gut wall with good bacteria to fend off pathogens.

Immunity
Probiotics are thought to support the immune system thanks to the ‘barrier effect’. A high quality probiotic is tested for its ability to bind to cells on the gut wall lining. When you supplement with plenty of probiotics they begin to coat your gut wall, taking up space on this lining. This means that when pathogens (harmful microorganisms) enter the body, they reach the gut and have fewer points on the gut wall upon which they can adhere. It’s effectively a competition for space, between the good guys and the bad! The more good guys (probiotics) you have lining your gut wall, the fewer bad guys (pathogens) you should have in turn. This is known as the barrier effect; taking a daily probiotic can support this process.

Probiotics also improve the absorption of vitamins and minerals into the bloodstream. After all there’s no use taking lots of vitamins if your body is not absorbing them. This improved vitamin uptake provides essential support for the immune system, and what’s more, means that a probiotic nicely complements any other daily supplements you may take.

Skin health
Probiotics are also thought to help support healthy skin, as often acne or spots are caused by bad bacteria, or toxins in the body. Supporting your gut with friendly bacteria means that the body will digest foods more efficiently (producing fewer toxins in the first place) and what’s more, probiotics help to displace toxins or bad bacteria in the gut (through various mechanisms, including the barrier effect mentioned above.) Probiotics have even been shown to help with atopic allergies such as eczema (6). Supporting your gut health from the inside should hopefully see you benefiting on the outside too.

Frequency of Use
Some specific probiotics can be effectively taken as a ‘one-off’ treatment, for example Saccharomyces boulardii to support gut health in those suffering from diarrhoea. However if you’re taking probiotics for general support to your digestion, immunity, energy & skin, best to take them every day for at least a few months; giving your gut time to top up its friendly bacteria levels. Many people safely and happily take probiotics on an ongoing basis for years.

Zinc may shorten common colds

As autumn and winter draw on, many of us are blighted by the common cold.  While there is still no cure for the virus, a new literature review indicates that a common supplement can reduce its duration.

Zinc may help the immune system
Studies have found that zinc and zinc lozenges may shorten the duration of the common cold by 40% (3)

The study, published in the Open Respiratory Medicine Journal, found that when given in higher doses, zinc and zinc lozenges may shorten the duration of the common cold by 40%.

There have been many studies on the effectiveness of zinc lozenges in treating colds, and results have not been consistent.  This new meta-analysis assessed 13 placebo-controlled trials in order to get a better picture of the effectiveness of the supplement.

Of the 13 trial studies, 5 used a total daily zinc dose of less than 75mg.  Each of these studies found no beneficial effect on cold duration.

Three trials used zinc acetate in daily doses of more than 75mg.  Each of these 3 studies found zinc to be beneficial, with an average of a 42% reduction in the duration of colds.

Five further trials used other forms of zinc in daily doses of more than 75mg.  Again, these trials showed benefit, with an average 20% decrease in the duration of colds.

While some studies recorded adverse effects such as unpleasant taste, no evidence was found that zinc lozenges might cause long term harm.  The study leader Dr Hemia concluded that “since a large proportion of trial participants have remained without adverse effects, zinc lozenges might be useful for them as a treatment option for the common cold.”

The therapeutic properties of zinc are thought to be due to this mineral’s ability to affect the immune response, as well as its antioxidant and anti-inflammatory properties.  In addition, zinc may actually inhibit the common cold virus (rhinovirus) (3).

For the common cold, zinc lozenges and sublingual zinc do appear to be a better option than zinc tablets or capsules.  This is because zinc lozenges dissolve in the mouth allowing the mucus membranes in the throat (and any cold virus there) to be acted on directly by the zinc.  Swallowing a capsule or tablet would not allow the zinc to work in the same way.

The trials that Dr Hemlia reviewed were each based on small numbers of participants, indicating that more research is needed in this area.  I would also add as a caveat that zinc is known to compete with other minerals in the body.  These minerals include copper and iron.  Long term intakes of high levels of any one mineral can reduce levels of another, a process called ‘competitive inhibition’.  Nevertheless, the study indicates that short-term intakes of high amounts of zinc should pose no harm, and may provide welcome relief for those suffering with winter colds.
