The market for energy-boosting products, ranging from mushroom extracts to caffeine tablets and teas, is under review as a pharmacist assesses their effectiveness. While many consumers seek quick solutions for fatigue, expert opinions suggest that the efficacy of these products varies widely and often lacks robust scientific backing.
Sultan Dajani, a pharmacist, provided his assessment of several popular high-street energy boosters. He noted that underlying causes of fatigue, such as poor sleep, high stress levels, hormonal fluctuations, and nutrient deficiencies, are often overlooked in favor of quick fixes. Dajani cautioned that consulting a GP or pharmacist is advisable for persistent symptoms or before trying new supplements, especially for individuals on regular medication.
Mushroom Extracts and Caffeine Products
Fourfive Lion’s Mane Mushroom capsules, which claim to support psychological function and energy with lion’s mane extract, guarana, and B vitamins, received a low rating of 2/10. Dajani stated that evidence for mushroom extracts is limited, with only a few small studies suggesting potential benefits for mood and focus. The guarana content provides a minimal amount of caffeine, unlikely to offer a significant boost, and the dosage in herbal pills can be unreliable.
In contrast, Pro Plus Fizz Hydration tablets, containing 75mg of caffeine, were rated 8/10. Dajani explained that this dose is sufficient for a noticeable energy boost by blocking adenosine, the chemical that induces sleepiness. He noted that caffeine is generally safe for most healthy adults in moderation, but advised caution regarding daily intake limits and potential side effects for individuals with anxiety or sleep issues. The added minerals in the fizzing tablet are unlikely to significantly impact energy levels unless dehydration is a factor.
The What Supp Co Protect Your Energy patches, containing 6mg of caffeine along with ashwagandha and B vitamins, received a score of 0/10. Dajani questioned the reliability of caffeine absorption through the skin, citing a study indicating low bloodstream delivery compared to oral tablets. The low caffeine dose and lack of evidence for effective skin absorption of other ingredients rendered the product a poor choice.
Boots Ginseng, Ginkgo & Guarana tablets, which combine ginseng, ginkgo biloba, and 75mg of caffeine, were rated 4/10. Dajani pointed to disappointing evidence for ginseng's efficacy in reducing fatigue, with some users reporting indigestion. He suggested that the caffeine from guarana is likely responsible for any immediate alertness, offering no significant advantage over a small cup of coffee.
Sugar-Based and Herbal Options
Lucozade Sport Energy Gel, a product designed for athletes, was rated 2/10 for general energy boosting. Dajani described it as primarily sugar, useful for endurance athletes needing quick fuel during intense exercise. For the general population, he stated that a balanced diet provides sufficient carbohydrates, and excess sugar can contribute to weight gain. Sugar provides brain fuel but not a stimulant effect like caffeine, leading to a short boost followed by a crash.
Kura Klub Energy Glow, an energy tea blend with yerba mate and guarana, received a 6/10. Dajani noted that any caffeinated tea could be considered an energy tea. While yerba mate compounds might theoretically slow caffeine release, robust evidence is lacking. The tea provides about 80mg of caffeine per cup, similar to a small coffee, with other herbs contributing mainly to flavor.
Berocca Energy tablets, containing B vitamins but no caffeine, were rated 3/10. Dajani emphasized that B vitamins do not provide instant energy and only help combat fatigue if a deficiency exists. He also pointed out that the high levels of certain B vitamins in the product are unnecessary and likely to be excreted, representing a waste of money for individuals not deficient.
Red Bull Sugar Free, containing 80mg of caffeine and taurine, was scored 5/10. Dajani warned that sugar-free options are not inherently healthier and long-term consumption may be linked to health risks. The caffeine content is comparable to a cup of coffee, and while taurine may complement caffeine's effects, evidence is limited. The product is advised for occasional use only and is not recommended for pregnant women, under-16s, or individuals with heart conditions.
Dextro Energy Orange + Vitamin C tablets, essentially sugar tablets with added vitamin C, received a 2/10. Dajani described them as a fast-acting sugar source that fuels muscles but does not provide the same boost as caffeine. He noted their potential utility for individuals experiencing hypoglycemia but considered them a waste of money for general use, with a risk of excessive calorie intake if consumed like sweets.
