Caffeine is the most consumed stimulant on Earth — but how much is actually safe?

Whether it’s your morning coffee, a pre-workout, or an energy drink, caffeine plays a role in millions of people’s daily routines. But too much — especially from synthetic sources or poorly formulated products — can lead to crashes, anxiety, and long-term burnout.

At Tilt Energy, we include 106mg of natural caffeine per 330ml can — a dose that hits the sweet spot between energy, focus, and stability, while staying well within Australia’s strict regulatory standards.

Caffeine and the body — what actually happens?

Caffeine works by blocking adenosine, a neurotransmitter responsible for making you feel drowsy. By interfering with adenosine, caffeine increases alertness and mental performance.

Key facts:

• Absorption time: 15–30 minutes

• Peak concentration: ~1 hour after consumption

• Half-life: 3–6 hours depending on metabolism

• Total duration: Can remain active for 8–10 hours

This makes dosing crucial. Too much caffeine — especially in one hit — can lead to overstimulation, jitteriness, or a sudden crash.

What do Australian guidelines say?

Food Standards Australia New Zealand (FSANZ) strictly regulates the maximum caffeine content in energy drinks:

“Energy drinks must not contain more than 320mg of caffeine per litre.”

For a 330ml can, this caps the legal caffeine content at 105.6mg.
Tilt Energy contains 106mg per can — right on the regulatory edge, formulated with precision to stay compliant while still delivering effective energy.

We don’t push the limits. We hit the optimal mark — and we do it cleanly.

Why 106mg? A dose backed by science

Clinical research shows that 100–150mg of caffeine can:

• Improve mental alertness and memory

• Enhance physical endurance

• Sharpen task-switching ability

• Improve mood in sleep-deprived states

Paired with 150mg of L-Theanine, the result is smooth, focused stimulation without the common side effects of high-caffeine drinks.

Tilt’s formula avoids:

• Jitters

• Overstimulation

• Heart palpitations

• Sleep disruption

This is energy you can use daily — without burning out.

Why natural caffeine > synthetic caffeine

Tilt uses naturally sourced caffeine, not the synthetic kind found in most mass-market drinks. Natural caffeine:

• Is absorbed more slowly and evenly

• Reduces the risk of a sudden energy crash

• May contain trace antioxidants

• Feels cleaner and smoother in the body

Synthetic caffeine, often lab-made and cheap to produce, can spike fast and drop hard — which is why you’ll feel wired one moment and wrecked the next.

So, how much caffeine is too much?

✔ For healthy adults: up to 400mg per day is considered safe
✔ For energy drinks: no more than 320mg per litre, per FSANZ
✔ For a functional lift: 100–110mg is ideal for most people

Tilt gives you 106mg — high enough to energise you, low enough to avoid side effects, and precisely formulated to meet FSANZ guidelines.
