6 Key Nutrients Every Singer Needs To Support Their Immune System

You'll know as a singer, your voice is your instrument. And just like any instrument, it requires care, maintenance, and the right support to perform at its best.

From a naturopathic nutrition perspective, supporting your immune system is a key part in maintaining consistent vocal health; reducing the risk of illness, and improving recovery between performances or lessons.

Here are six essential nutrients that can help keep both your body and your voice in optimal condition:

1. Zinc

Essential for immune defence and tissue repair, zinc may help reduce the duration of colds and support recovery. Zinc is an important antioxidant which increases immune cell activity, meaning our body is more prepared to fight against illnesses or disease. Its anti-inflammatory properties and ability to prevent replication of viral activity make it a must have staple in any singers diet.

Food sources: sesame seeds, Brazil nuts, pecans, rye flour, oats, adzuki beans, chickpeas, lentils, pumpkin seeds, cashews.

2. Vitamin A

Vitamin A supports the health of mucous membranes, including those in the throat and vocal tract. Keeping these tissues well-nourished helps maintain vocal clarity and reduces irritation.

Vitamin A comes in 2 forms, Pre-formed Vitamin A (active form found only in animal products that the body can already use) and Pro-formed Vitamin A (found in non-animal foods which needs to be converted within the body into an active or usable form) and are best absorbed when fat is consumed.

Food sources: carrots, squash, mango, spinach, red peppers, kale, sweet potatoes, liver, fish liver oils, egg yolk, mackerel, salmon.

3. Vitamin D

Often known as the “sunshine vitamin,” yet argued that it's not strictly a vitamin as it is synthesised in the skin in response to sunlight. Vitamin D plays a key role in immune regulation. Low levels are common in the UK and have been linked to increased susceptibility to illness, which may directly impact vocal performance and consistency.

Vitamin D is a vitamin that should be tested before supplementation yet it is one that I give to the majority of my clients. This is because it is a fat-soluble vitamin which is stored within the body, therefore it is easy to take too much. You can get your Vitamin D tested by your GP so you know how much to supplement.

Your best source is getting it directly from sunlight and supplementing in the winter months.

Food sources: mushrooms, oily fish, egg yolks, dairy.

4. Vitamin C

Vitamin C is a powerful antioxidant that supports immune function and helps combat oxidative stress. It may also aid in reducing inflammation, supporting faster recovery when you’re feeling run down.

Any kind of stress (psychological, chemical, emotional or physiological), fever, viral illness, alcohol, smoking and even the oral contraceptive pill can increase the excretion of vitamin C meaning if or when you experience any of these, your need for vitamin C will be higher.

Food sources: Red pepper, kiwi, citrus fruits, papaya, tomatoes, strawberries, broccoli, Brussel sprouts.

5. Probiotics

I know I harp on about probiotics but they are the key in supporting gut health. Gut health plays a central role in immune function and a balanced gut microbiome may help reduce inflammation and improve resilience to illness.

Think of probiotics as being the bugs in your gut. It's important to have a diverse range of these bugs. You can get this from your diet but if you read any of my other blogs, you know I'm a big fan Symprove. Symprove is a live-bacteria supplement which is backed by scientific research which is why I'm a big fan and have used it personally.

Food sources: natural yoghurt, kimchi, kefir, miso, tempeh, sauerkraut.

6. Prebiotics

Prebiotics are the food for your beneficial gut bugs which will help probiotics thrive. I see so many clients spend so much money on supplements and probiotics but if you're not feeding them as if you're looking after a tamagotchi, there is no point in buying any of this. Your gut bugs love fibre. Fibre is found in plants. Fill your meals with fruit, vegetables, wholegrains, herbs, spices, beans, nuts and seeds. And focus on including;

Food sources: garlic, onions, leeks, asparagus, oats, bananas.
