Most guarana supplements are single-ingredient products positioned as cheap caffeine alternatives or fat burners. This formula combines four ingredients that work through different but complementary mechanisms: guarana and yerba mate for sustained natural caffeine release, L-carnitine for mitochondrial metabolic energy, and bromelain for absorption support. The result is a broader, more complete energy and cognitive support formula, not just a stimulant delivery system.

Neither. This is a clean daily energy and cognitive support supplement designed for consistent, moderate daily use. It is not formulated as a high-stimulant pre-workout product, the guarana dose is 75mg per capsule, which delivers a gentle and sustained caffeine effect rather than an intense stimulant hit. It is equally at home on a work desk as it is in a gym bag.

Synthetic caffeine anhydrous is absorbed very rapidly, plasma caffeine peaks within 30 to 60 minutes and drops off sharply, producing the familiar spike and crash pattern. Guarana's caffeine is bound to tannins and saponins in the whole plant matrix, slowing its absorption and producing a more gradual rise and fall in plasma caffeine. This translates to a longer, smoother energy lift with less risk of jitteriness or abrupt energy drops. Multiple human clinical studies have confirmed that guarana improves cognitive performance, memory, reaction time, and concentration, at low doses, with effects that appear attributable to more than just caffeine alone.

Yerba mate (Ilex paraguariensis) is a South American plant traditionally consumed as a tea, well known for its energising and focus-enhancing properties. It contains caffeine alongside two other methylxanthines, theobromine and theophylline, which produce mild cardiovascular and bronchodilatory effects at the doses provided. Yerba mate also contains chlorogenic acids and quercetin, providing antioxidant activity alongside its stimulant profile. Combined with guarana, it creates a more rounded and sustained natural energy effect than either ingredient alone.

Take one capsule in the morning or early afternoon. For most people, taking it with or shortly after breakfast works well, the sustained caffeine release means the energy effect will carry through the morning and into the early afternoon. Avoid taking it after 2pm if you are caffeine-sensitive, to minimise any potential effect on sleep onset.

The recommended dose is one capsule per day. This product is designed for consistent daily use at a moderate stimulant level rather than high-dose acute stimulation. Exceeding the recommended dose is not advised.

Most people notice the energy and focus effects within 30 to 60 minutes of taking the capsule, reflecting the onset of the guarana and yerba mate caffeine. The metabolic and cumulative benefits of L-carnitine develop over two to four weeks of consistent daily use, carnitine's effects on mitochondrial efficiency are gradual rather than immediate.

Yes. Guarana Energy Complex pairs well with the broader Phenome+ range. It can be taken in the morning alongside other daily supplements. Note that if you are also taking Bromelain from the Phenome+ range, you will be getting additional bromelain from both products, this is safe but worth being aware of when planning your stack.

Yes. All four active ingredients are plant-derived and the capsule shell is vegetable cellulose. The product is fully vegan, non-GMO, and free from gluten, dairy, soy, and artificial additives.

This product is not suitable during pregnancy or breastfeeding. It should be used with caution by anyone sensitive to caffeine, those with heart conditions or anxiety disorders, and those taking medications that interact with caffeine, including certain antidepressants, blood pressure medications, and stimulant medications. If you are in any doubt, consult your GP or pharmacist before use.

This product is free from the 14 major allergens under UK food labelling regulations. It is also non-GMO and free from artificial additives. Note that yerba mate is derived from the Ilex paraguariensis plant, individuals with known sensitivities to plants in this family should consult a healthcare professional before use.

Yes. The formula is designed for consistent daily use at a moderate stimulant level. The guarana dose of 75mg per capsule is gentle compared to most energy and pre-workout products on the market. Long-term daily use is appropriate for healthy adults who are not sensitive to caffeine and who do not have contraindicated medical conditions.

L-carnitine is an amino acid derivative that plays an essential role in mitochondrial energy metabolism, specifically in transporting long-chain fatty acids across the inner mitochondrial membrane, where they are oxidised to produce ATP. This is a fundamentally different energy mechanism from caffeine's adenosine receptor antagonism. While guarana and yerba mate stimulate alertness by blocking the adenosine receptors responsible for fatigue signalling, L-carnitine improves the efficiency of the metabolic process that actually produces cellular energy. The two mechanisms complement rather than duplicate each other.

Bromelain serves two roles in this formula. First, as a proteolytic enzyme, it supports protein digestion and reduces any gastrointestinal discomfort that can occasionally accompany stimulant supplements when taken on an empty stomach. Second, bromelain has a well-documented ability to enhance the bioavailability of other compounds, a property that improves the absorption efficiency of the whole formula.

The formula contains 75mg of guarana seed extract and 75mg of yerba mate leaf extract per capsule. The caffeine content will depend on the concentration of the specific extracts used. As a reference point, guarana extract typically contains approximately 22% caffeine, meaning 75mg of extract delivers roughly 16mg of caffeine from guarana. Yerba mate extract contributes additional caffeine and methylxanthines. The total caffeine content per capsule is modest, significantly less than a standard cup of coffee, which is deliberate. This is a sustained-effect formula, not a high-dose caffeine product.

No. The formula contains only the four active ingredients and a vegetable cellulose capsule shell. There are no magnesium stearate, silicon dioxide used as a filler, rice flour, or other manufacturing excipients commonly found in mass-market energy supplements.
