    WHAT IS AN AUTOIMMUNE DISEASE?

    Your immune system is meant to safeguard your body against the risk of disease and infection, and to this end, can normally tell the difference between the body’s own cells and any foreign cells from external sources. When, however, your immune system fails to distinguish between your own cells and unwelcome foreign invaders, it can end up mistakenly attacking your... Read More

    WHAT TEMPERATURE IS A FEVER?

    With a fever reported to be the most common symptom of COVID-19, the above is a very pertinent question.

    ASK AN EXPERT: HOW DOES STRESS AFFECT MY IMMUNE SYSTEM?

    The reason why stress affects us so much is that our body really hasn’t changed much in 60,000 years. Cortisol is a stress hormone produced in the adrenal glands (little glands that sit on top of the kidneys) which are hard wired to the body’s ‘fight or flight’ survival response. 60,000 years ago this would’ve been essential to either fight...

    MYTHBUSTING VITAMIN DOSE: *SPOILER ALERT* YOU PROBABLY NEED TO UP YOURS

    Myths, a widely held but false belief or idea. They are something we all hear in our daily lives, but where do they come from and why do they often need busting in accordance with the truth?

    IS YOUR PET THE KEY TO BETTER IMMUNITY?

    Ask almost any pet owner, and they’ll tell you that owning and looking after their beloved dog, cat or other furry or feathered friend has definitely been good for their health.

    It’s very much the responsible thing to take the time to actually read the labels of the vitamin supplements you’re comparing in a high-street health store, or for that matter, to scrutinise the specifications you might see listed for such products online.

    CAN YOU SHOCK YOUR IMMUNE SYSTEM INTO WORKING HARDER?

    It’s an enticing idea for many of us; the idea that we can somehow trigger our immune systems into action via some kind of immediate ‘shock’ or trauma.

    The appendix, the small, never thought of organ that most misconceive of as redundant.

    THE THREE MOST IMPORTANT THINGS ABOUT VITAMIN C: DOSE, DOSE, DOSE

    We’re one of the few mammals (aside from guinea pigs, primates and fruit bats) that can’t make our own vitamin C. And when we eat it in our food, the body finds it difficult to store it. That’s because it’s a water-soluble vitamin, which is less stable versus the fat-soluble vitamins A, E, D and K that are stored for... Read More

    Vitamin C is definitely an immune system multitasker! There’s been a mountain of research since the 1930s on its use as an antiviral, and even though there continues to be much debate over whether it can prevent the common cold, there is scientific consensus that it can help us get rid of it quicker (1).

    Vitamin C is a water-soluble vitamin that isn’t stored very well in the body.

  • High doses of Vitamins represented by a large tree

    WHY TAKING 1875% OF YOUR RDA OF VITAMINS COULD BE A GOOD IDEA

    The definition of Recommended Daily Allowance (RDA) fails to consider is that there is a big difference between the RDA (the amount you need to avoid deficiency) and the amount of a vitamin or mineral we need to achieve optimal nutrient levels for optimal health. Optimal health and peak performance are very different from this commonly understood guideline. We explore how this came to be.
