Product analysis
Elite may help with short-term alertness and attention through caffeine, while theanine may ease tension during demanding tasks. Caffeine adds stimulation, which matters if your main aim is relaxation.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality20
Caffeine and theanine forms are not specified, which limits confidence in form quality. Their stated amounts do not resolve that uncertainty.
Ingredient Transparency63
Both active amounts are clearly stated, making the serving easy to compare. Neither ingredient form is specified, so identification is less complete.
Value For Money80
Both caffeine and theanine offer good value for the amounts provided. Their contributions give a clear basis for comparing the cost with similar formulas.
Customer Satisfaction77
Customer ratings are generally positive across several thousand ratings. That provides useful evidence of satisfaction, without showing which effects customers noticed.
Product Focus66
Two ingredients keep the formula simple, with its clearest role in short-term alertness and attention. Broader aims such as lasting weight loss or mood improvement have weaker support.

Goals
Impact
High effect
Caffeine · 100 mg
Caffeine can improve short-term alertness and reduce sleepiness. Theanine has limited support for particular outcomes when taken with caffeine, but a standalone fatigue benefit or universal reduction in jitteriness is not established. Their combination therefore does not demonstrate a broader or longer-lasting energy effect.

Ingredient fit79
Caffeine, Theanine are included at declared amounts, with partial coverage of the saved comparison ranges.
Goal fit
Caffeine, Theanine account for the relevant ingredients; the product is also linked to other goals.

High effect
Theanine · 200 mgCaffeine · 100 mg
Caffeine can support acute alertness and attention, although timing, tolerance and sleep loss can change its practical effect. Theanine has limited standalone evidence for fewer sustained-attention errors; a larger amount or combination with caffeine does not establish greater benefit. Attention and memory findings do not establish better work output.

Theanine · 200 mgCaffeine · 100 mg
Caffeine supports alertness and sustained attention, while theanine has a narrower connection to selective attention. Both declared amounts meet the saved amount criteria for the selected serving. Theanine findings remain mixed across tasks, and the supplied information does not establish an added benefit or reduced jitteriness from combining it with caffeine. Optional repeated servings are separate from this one-serving result.

Impact
High effect
Theanine may support short-term attention and calm focus. Small studies support a limited acute role, without establishing lasting cognitive improvement or neuroprotection. Caffeine can support acute alertness and attention. Their presence together does not establish an additional combination benefit, and the 200 mg theanine serving is not evidence of sustained cognitive improvement.
