What is an intra-workout supplement?
An intra-workout supplement is consumed during exercise not before or after to sustain performance, hydration, and recovery in real time. Typical formulas combine fast-digesting carbohydrates (to replenish muscle glycogen), essential amino acids (to support muscle protein synthesis), and electrolytes (to replace minerals lost in sweat). For example, Gaspari Nutrition's SizeOn one of the original intra-workout formulas, launched in the 2000s and known as the 'King of Creatines' delivers 40g of carbohydrates (Dextrose, Trehalose, Cluster Dextrin®), a full essential amino acid profile via Amino9®, 6g of creatine, and a six-mineral hydration complex per scoop.
What does science say about consuming carbohydrates during exercise?
Research consistently shows that intense training depletes muscle glycogen, and glycogen depletion directly reduces power output and time to fatigue. Consuming 30–60g of fast-digesting carbohydrates per hour during sessions lasting 60+ minutes helps maintain blood glucose and sustain performance. This is why intra-workout formulas like Gaspari's SizeOn dose 40g of multi-source carbohydrates per serving enough to cover a full training hour.
Who invented the intra-workout supplement category?
Gaspari Nutrition's original SizeOn, launched in the mid-2000s by bodybuilding legend Rich Gaspari, is widely credited as the first mainstream intra-workout creatine drink it pioneered the category and earned the nickname 'King of Creatines.' The formula has been updated repeatedly since, most recently in 2026 with Amino9® EAAs, HMB, and 6g of creatine.
Is creatine effective when taken during a workout?
Creatine works through muscle saturation, so daily consistency matters more than exact timing taking it during training is as effective as any other window and more convenient. The established effective dose is 3–5g per day. Gaspari SizeOn includes 6g of creatine (monohydrate + disodium creatine phosphate) per serving, covering the full daily requirement on training days.
What is HMB and does it help build muscle?
HMB (β-hydroxy β-methylbutyrate) is a metabolite of the amino acid leucine, studied for its role in reducing muscle protein breakdown — particularly relevant during calorie deficits, high-frequency training, or for preserving lean mass. It's a newer addition to intra-workout formulas; Gaspari's 2026 SizeOn reformulation added calcium HMB to its protein synthesis matrix for exactly this anti-catabolic purpose.
