Energy Strips

Coffee and energy drinks give you caffeine — but they also come with 27–54g of sugar, artificial dyes, hundreds of calories, and an unpredictable crash 1–2 hours later. One Glenari Energy Strip delivers 50mg of caffeine paired with 30mg of L-Theanine — a combination that clinical research shows produces focused, calm energy rather than a jittery spike. L-Theanine smooths caffeine's rough edges: no jitters, no anxious heart rate, no mid-afternoon crash. The strip is also zero sugar, zero calories, and zero artificial sweeteners (sweetened only with Stevia). And unlike a coffee or energy drink, it fits in your pocket and requires nothing except your tongue.

This is exactly what L-Theanine is for. Each strip contains 30mg of L-Theanine alongside 50mg of caffeine — a 1:1.67 ratio that mirrors what research has consistently shown to reduce the jitter response without dulling alertness. L-Theanine promotes alpha brain wave activity (the same state associated with calm focus) and modulates the stimulant response of caffeine. The result is clean, sustained energy rather than a spike-and-crash cycle. No sugar also removes the secondary crash mechanism common in energy drinks. If you're particularly caffeine-sensitive, start with half a strip to gauge your response.

We recommend up to 1 strip per day. Each strip contains 50mg of caffeine — roughly equivalent to a medium espresso. The FDA considers up to 400mg of caffeine per day safe for healthy adults, so a single strip is a conservative dose. If you already consume coffee or other caffeinated products, count your total daily caffeine intake across everything. Avoid taking a strip within 4–6 hours of bedtime as caffeine can affect sleep quality. Energy Strips are not recommended for pregnant or nursing mothers, children under 18, or individuals with a known medical condition without consulting a physician first. If in doubt, speak to your healthcare provider.
