Supplements: The good, the bad and the ugly

Taking vitamins makes us think we’re doing something good for our health, but are we?

Supplements: The good, the bad and the ugly

With chemist shelves stocked floor to ceiling with supplements claiming outlandish health benefits, determining what you do and don’t need can be a herculean task. And just to make it all a little more confusing is the fact that different people do or don’t need certain supplements.

Despite what many of us would like to believe, simply taking a multivitamin isn’t enough to counteract an unhealthy diet. In fact, health experts can’t even seem to agree on whether they’re good for you at all. Taking a mixture of vitamins may even be harmful, considering some vitamins and minerals can be damaging to the body in too high a dosage. It’s best to get your vitamins and minerals through the food in your diet, unless otherwise specified by your doctor.

The bottom line: it’s best to avoid these unless otherwise directed.

Vitamin D
Vitamin D is made by your body when you’re exposed to sunlight, and can also be found in tuna, salmon and fortified foods. It can help your immune system function, bone strength, regulates the absorption of calcium and phosphorus and can improve your resistance to certain types of disease. If you are deficient in vitamin D, there are supplements you can take to help achieve a healthy level in your body. However, some large studies have shown that vitamin D supplements offer no benefits to otherwise healthy adults, but that taking too much of the vitamin can actually be bad for your body.

The bottom line: if you’re deficient in vitamin D these supplements are helpful. However, they can be harmful if you haven’t been told by your doctor that you are deficient.

Fibre can help to improve digestion, lower cholesterol levels, control blood sugar levels, weight maintenance and bowel health. It can be found in a wide variety of foods including fruits, nuts, legumes, wholegrains, seeds and vegetables. Only 5 per cent of people are getting the amount of fibre they need each day. It’s best to get your fibre from foods because they also contain the vitamins, minerals and nutrients your body needs. However, supplements can help you to achieve your daily recommended intake of fibre.

The bottom line: it’s best to get your fibre from your diet but, if you can’t, supplements can be helpful.

Joint supplements
Glucosamine and chondroitin and are naturally found in human cartilage and is also sold as a popular supplement. While some people say that they find relief using these supplements, recent research suggests otherwise. Some studies praise the supplements, while other suggest that they have no positive – and potentially even negative – effects. In fact, some side effects of a test on glucosamine and chondroitin included abdominal pain, diarrhoea, drowsiness, headaches, heartburn and even allergic reactions (especially for people with allergies to shellfish).

The bottom line: it’s best to avoid taking joint supplements such as glucosamine and chondroitin as research-based evidence has found them to be harmful.

Probiotics, or ‘good’ bacteria, can change the balance of good and bad bacteria in your body and have a range of health benefits. They can help to lower your cholesterol, support your immune system and weight loss, ease skin irritations and improve your digestion. Probiotics can be found in fermented foods such as kombucha, sauerkraut, miso and yoghurt. Research suggests that taking probiotics can help to improve the symptoms of some mental health disorders such as anxiety, depression, stress and memory loss. Some evidence suggests that taking a range of probiotics is more effective than taking a single strain. While both probiotic supplements and fermented foods are beneficial, it’s important to remember that some probiotics can be destroyed by stomach acid and will be destroyed before they reach your gut. Many of the studies that produce the most positive results required participants to consume a high dosage of between one billion and 100 billion live organisms or colony-forming units (CFU) daily.

The bottom line: probiotics can be found in food and supplements, both of which offer a range of health benefits.

Vitamin C
One of the more popular supplements on the market, vitamin C claims to help prevent or shorten the length of colds. However, there is limited research supporting this. Vitamin C is also easy to find in your diet. Just half a cup of red capsicum, or three-quarters on an orange can give you more than your recommended daily intake.

The bottom line: vitamin C is easy to find in your diet, so supplements are likely a waste of money unless otherwise directed by a doctor.

While most people are able to get the vitamins, minerals and nutrients that they need from their diet, supplements may be prescribed by doctors in the case of deficiencies or complications.

Do you take supplements? Would you take supplements without your doctor recommending them to you?

    I have resolved to take 1 x Cartia Aspirin each day in the hope that it will help prevent me getting Bowel cancer. I read about this in a book written by a West Australian doctor. He also advised that 3 cups of coffee per day were good value and that 500mg of Vitamin B3 per day would help repair sun damaged skin.

    I would suggest you do some of your own research rather than take this doctors word for it.
    9th Jul 2020
    Not sure that I understand your post Incognito, reading the book was in fact the culmination of my research into Cartia and Coffee and proof of what I had learnt prior.

    If the doctor has cited evidence of his claims then I would like to see them, I merely suggested you don't take one book written by a doctors word unless you have done your research, so that is good if you have. Asprin and coffee in my opinion (and from my research) are not good for bowels because they are acid producing. I have done a lot of research when I had IBS which doctors could not help me with and cured myself.

    100 mg aspirin per day is good for stopping blood clots too if you have high cholesterol.
    Coffee is s scientifically proven to have many benefits. I won't try to comment about vitamin B3 because I don't know anything about it. The doctor does.
    Incognito always tries to be helpful but she has no qualifications for giving advice except a kind heart .

    I have Crohns Disease (not on any meds) so immune system weakened and some foods cannot tolerate - try to eat a good mix of healthy food but have blood tests twice a year and GP advises me if anything needs adjusting - sometimes my protein levels are low, other times it might be B12 or Vit D - then I do as I am told and GP monitors.

    So bottom line is as the article suggests, eat a healthy diet. But if you only eat cooked food yo may not be getting enough nutrients, so keep up some raw. Cut down or out processed dead foods. Living sprouts are exceptional in vitamins and nutrients, so get sprouting.
    I take Vitamin D (when I don't get enough sun) and B12. And don't believe the hype that it is easy to overdo it with Vitamin D, it is quite hard to do. Get your levels checked before and after taking supplements.

    Have taken good quality supplements for many years and have experienced excellent health and very rarely get a cold or flu. So I'm happy to keep up the regime.
    10th Jul 2020
    You must also eat healthy too, I also never get colds or flu's. What are the good quality supplements?, I am always looking for recommendations.
    10th Jul 2020
    "Glucosamine and chondroitin................and even allergic reactions (especially for people with allergies to shellfish)."

    The companies making vegetarian glucosamine did not tell people when they switched from flora based glucosamine to using shellfish which counts as suitable for vegetarians.

    As a result I ended up in hospital because I am highly allergice to shellfish in all forms.

    People should make sure they check the label of any vitamins they are taking to make sure something other than the usual items in the tablets hasn't be replaced with something that can harm them.
    10th Jul 2020
    Yes very important to check ingredients, contact the manufacturer to be sure too. Look up reviews also helps.
    10th Jul 2020
    Recommendations: "... unless otherwise directed/specified by a doctor." are o.k., IF you can get to a GP who knows ...
    E.g. 'Glucosamine and chondroitin' have been proven to assist with 'joint problems' and I personally know that Zinc helps with male urinary tract problems.
