How to Choose a Truly Healthy Drink (Without Falling for the Hype)

9 April 2025

The wellness drink market is full of clever marketing, but not every “health” drink is actually good for you. Many are loaded with hidden sugars, artificial ingredients and preservatives. So how do you separate the real deal from the imposters?

Here’s a no-nonsense guide to choosing healthy functional drinks that actually support your wellbeing.

1. Read the Ingredient List, Not Just the Label

Forget the flashy claims on the front of the bottle. The real story is in the ingredients. Most functional beverages are sold on hype, so it’s critical to read what’s actually inside.

What to look for

  • Short, simple ingredient lists. The fewer, the better.
  • Recognisable ingredients: real fruits, herbs and botanicals.
  • No artificial preservatives or stabilisers. Natural preservation like citrus extracts is best.

What to avoid

  • Gums and fillers like carrageenan and xanthan gum, which may disrupt gut health.
  • Sodium benzoate and potassium sorbate, preservatives that can impact digestion.

Example: A mango-flavoured drink should contain real mango extract, not just “mango flavour.”

2. Check the Sugar Content

Many so-called healthy functional drinks contain as much sugar as soft drinks. Brands get sneaky by using alternative names like:

  • Agave syrup, which is even higher in fructose than sugar
  • Fruit juice concentrates, stripped of fibre and leaving just sugar
  • Coconut sugar, honey and maple syrup, which are still sugar and still high-GI

Quick rule

  • 5g sugar per 100ml or less? Good choice.
  • More than 10g per 100ml? Probably a sugar bomb.

Better choice: Drinks with no added sugar, like every Tonic Alchemy functional shot.

3. Watch Out for Preservatives and Additives

Shelf-stable drinks often rely on preservatives and stabilisers to extend their life, but at what cost?

Common preservatives to avoid

  • Sodium benzoate (211), which can react with vitamin C to form benzene (Cancer Council Australia).
  • Potassium sorbate (202), which can irritate digestion.
  • Carrageenan and emulsifiers, which have been linked to gut inflammation.

Better alternatives: Drinks preserved naturally with lemon juice, antioxidants or fermentation.

Example: Many plant-based milks contain stabilisers and gums. Opt for ones with just nuts, water and sea salt.

4. Look for Real Functional Benefits

A healthy functional drink should do a specific job, not just hydrate you. But not all functional beverages deliver on their promises.

How to choose a healthy functional drink

What to look for

  • Named ingredients with the dose per serve disclosed.
  • Probiotics and prebiotics, but check they’re clinically backed strains and meaningful amounts.
  • Natural electrolytes from coconut water, sea salt or trace minerals.

Red flags to avoid

  • “Collagen-boosting” drinks with no actual collagen or supporting nutrients.
  • “Gut-friendly” sodas full of artificial sweeteners that disrupt gut bacteria.

Better choice: Drinks with real, disclosed functional ingredients, like Tonic Alchemy’s Prebiotic Sodas with 5g of fibre per can, or DIGEST, built around the DigeZyme® enzyme complex.

Final Checklist: Is Your Drink Actually Healthy?

  • Short, clean ingredient list, with nothing artificial or vague
  • Less than 5g sugar per 100ml, from whole-food sources
  • No artificial preservatives or stabilisers
  • Real functional benefits, not just buzzwords
