Interval Supplements

At a Glance
Interval Supplements delivers a compact, flavour-forward approach to pre-workout and hydration for athletes who demand results without compromise. The 60ml pre-workout shots and summer-fruit electrolyte packs are designed to be convenient, tasty and effective, with no tingles or post-session crashes. High demand — currently selling out — reinforces credibility, though it may make immediate purchasing tricky. Bottom line: a refined, athlete-first option for high-intensity training that prioritises real taste and clear-headed performance.
Core Features
Interval focuses on two core product lines: single-serve pre-workout shots in flavours such as cherries & berries, watermelon, and apple & mango, and electrolyte performance hydration packs in summer fruits flavour. Each pre-workout shot is 60ml for portability and rapid use, formulated to support both body and mind through a blend of adaptogens and nootropics. The range emphasises natural flavourings and promises no side effects like tingles or energy crashes, while electrolyte packs target in-event hydration and recovery.
Pros
- No side effects like tingles or crashes: The formulations are explicitly designed to avoid the common stimulant after-effects that can undermine performance or recovery.
- Great taste using natural flavourings: Natural-flavoured options mean you’re less likely to dread the sip — the taste is a deliberate focus, not an afterthought.
- Convenient 60ml shot instead of bulky powders: Single-serve shots remove measuring, mixing and mess, making them ideal for pre-session routines.
- Supports both physical and mental performance: Adaptogens and nootropics work together to boost energy and sharpen focus during intense sessions.
- Positive customer reviews highlighting effectiveness and taste: Customer feedback reinforces that the product behaves as promised in real workouts.
Who It’s For
Supplement business selling pre-workout and electrolytes that utilise natural ingredients. We target those doing high intensity sports. Interval Supplements is ideal for individuals who perform regular, demanding workouts and want a fuss-free, delicious boost without stimulant hangovers. If you race, compete in Hyrox, or push through daily high-intensity sessions and value portability and flavour as much as function, this is designed for you.
Unique Value Proposition
Interval’s differentiator is surgical focus: natural-flavoured, shot-format pre-workouts paired with performance electrolytes designed for high-intensity athletes. Rather than a crowded ingredient list aimed at gimmicks, Interval offers targeted adaptogens and nootropics to enhance endurance and cognitive clarity, all in a portable format that fits a training bag or pocket. The deliberate choice to avoid common side effects removes a major friction point for athletes who need consistent, repeatable performance across sessions. Limited SKUs are a conscious design choice — depth over breadth — so each product is refined for taste, solubility and effect. High sell-through rates and customer praise for flavour and function position Interval above competitors who sacrifice taste or convenience for marginal performance claims.
Real World Use Case
Picture arriving at the gym with five minutes to spare: you shake a 60ml shot, taste a bright burst of cherries & berries, and head into a 45–60 minute Hyrox-style session feeling focused and physically primed, without jittery hands or an afternoon crash. During long sessions or races, the summer-fruit electrolyte packets keep hydration and mineral balance steady, helping you maintain pace and mental clarity.
Pricing
Starting at £9.99 for a pack of 6 pre-workout shots; electrolyte hydration packs are £19.99 for 20 packets. Note: some lines are currently sold out due to high demand.
