Fun, Facts & Fitness from Mary Morris MSc.

Around this time of year, I do start to think about what I might need as a supplement to stay healthy and free from illness throughout the winter months.
I eat a very healthy and nutritious diet most of the time and I exercise regularly, so am I lacking in anything specific that would make a difference to my overall health? Supplements can be expensive and they have a reputation for ‘not being any use’ if we already take plenty of each of the important nutrients in our daily diet.
However, recently I have learned that there is a strong link to not only the value of taking some of the key vitamins and minerals as a supplement but, even more importantly, the importance of when we take them in the day, to maximise their absorption and effectiveness.
It would be impossible to cover every vitamin and mineral vital to our body in this issue of the Newsletter but I have referred to Age UK, who have renowned experts advising them on the best supplements for those of us in the older age group. So, I have picked out a few nuggets of information that may help you decide if you need to supplement or not.
Vitamin D
I have previously told you of the benefits of supplementing with Vitamin D3 between October and March in the UK, as we cannot get enough of this vital vitamin from exposure to the sun. It is needed for the very important job of absorbing calcium in the body, keeping bones, teeth and muscles healthy as well as supporting your immune system. What I have not told you before is that evidence shows it needs to be taken with food (preferably your largest meal of the day) to ensure the highest level of absorption. I have taken it for several years now as I have always understood how important it is, but now I take it in the evening with my evening meal. Good to know – I hope you agree!
A good level of Vitamin D3 in the body has been linked to aiding recovery from, or even preventing, COVID-19 but more research is needed to confirm this. Interesting though.
Calcium
This is needed for building bones and keeping teeth healthy. What you may not know is how important it is for our muscle contractions too, including our heart, ensuring that our blood ‘clots’ normally. Basically, if we have 3 - 4 portions of dairy foods every day, we will be getting enough calcium. A supplement only needs to be taken when advised by your GP. It becomes necessary where there is an increased risk of a fracture, especially among frail, housebound patients. If you are taking a calcium supplement you should have been advised to take it with food, so it is not being absorbed on an empty stomach.
Iron
Iron is needed for making red blood cells which carry oxygen around the body and if we are a meat eater then our daily diet will be providing enough. If we are vegetarian or vegan, we need to explore the best way to get enough with foods such as dried fruits, nuts, beans, chickpeas, quinoa and fortified breakfast cereals. A fascinating fact is that if we have had an iron-rich meal we should avoid drinking tea with it. A 2017 study of UK women found that drinking tea even one hour after a meal reduced the absorption of iron by a massive 50%! So, try leaving your tea drinking to between meals!
B Vitamins
There are several different B vitamins with several different roles in the body but basically, they keep the nervous system healthy and help to release energy from food. They also keep the skin and eyes looking vibrant. You should get enough from wholegrains and cereals but as we get older it becomes harder to absorb Vitamin B12 and it can end up passing straight out of the gut as waste without being absorbed. This means it is a good idea to up your protein intake of meat, fish, eggs, milk and cheese to reduce the risk of anaemia and memory loss. If you do need to supplement then a maximum of 2mg a day is enough.
Vitamin C
Vitamin C is a water-soluble vitamin and so is best absorbed first thing in the morning and on an empty stomach, making a small glass of orange juice a very useful start to the day. My hubby and I stopped having our usual glass of fruit juice a while ago and have a large orange instead, so we get the added fibre and not so much of a sugar rush. This vitamin is a strong anti-oxidant and hugely aids our immune health and needs to be taken every day. If you are regularly having five or more portions of fruit and vegetables every day then you are well covered.
Fish Oils
I know that many of you may be taking a fish oil supplement, possibly because you don't like to eat oily fish, which makes it a good move. They are well known for reducing inflammation in the joints and they also support our brain and heart health. Timing when you take it is key here though. Don't take it in the early morning on an empty stomach. It should always be taken with a meal to help absorption. Your meal will include some fat, and that is what triggers the pancreas to break down the omega-3 oils into tiny fragments that are small enough to enter the gut wall. Then they can do their job!
It is so easy to feel confused about what to do for the best here. I hope this bit of a guide proves helpful, but always refer to your GP if you have any concerns about any aspect of your health that may be linked to a deficiency in any of these important compounds. I recently had a blood test where my folate was found to be slightly low and am now on a course of folate for a period of four months. When I asked why, I was told 'Because of your age'- not what any of us want to hear!
