What is food supplement?

“Any food the purpose of which is to supplement (add to or enhance) the normal diet and which is a concentrated source of a vitamin or mineral or other substance with a nutritional or physiological effect.” – Food Standards Agency.

Please remember that it is not an alternative to food, nor a quick fix for a poor diet. Too much of one supplement can cause side effects so always seek advice from your doctor first.

  • Folic acid food supplements are really useful in some cases because it helps to prevent birth defects during pregnancy.
  • Finally, they are an easy way to get all the vitamins and minerals you need.


  • Overdosing can cause harmful side effects. For instance, too much vitamin A (Hypervitaminosis A) can be toxic and lead to liver and brain damage.
  • Food supplements aren’t as strictly regulated as legal drugs. Thus products sold from suppliers outside the UK and Europe may not pass our safety standards. Avoid “DNP” as it speeds up the metabolism too quickly and has been linked to deaths.
  • Finally, keep in mind that they can react to medication you are currently taking and leading to side effects.

What food supplements are best for me?


Proteins can help people who want to lose fat, gain muscle and enhance their performance.

Proteine often comes in powder that you can add to your meals or into food supplement drinks. It helps to build muscle and body tissue, boost recovery and improve physical performance. Besides, some people use it for weight loss and muscle gain. Indeed, a high protein diet works by speeding up your metabolism which allows you to burn more calories. It also reduces your appetite, naturally reducing your calorie intake.

We are not big fan of proteins as it can cause frustration according to us. Spending your time eating powder sounds like no fun to us but it is something we think you should be aware of.

Are protein supplements healthy?

Not if they are being used as a meal replacement. Protein shakes, bars and tablets aren’t an alternative to a full meal. They should only be top-ups for those who want a high-protein diet. However, eating more foods that are rich in protein can be just as effective as protein supplements. This is a more natural and healthier option. As vegans, we can eat more quinoa, lentils, pulses, beans, tofu, soy and nuts (almonds, cashews and flaxseeds).
