Maltodextrin. Fructose. The formula in full — nothing added, nothing hidden. A clean two-ingredient product is harder to make well than a twenty-ingredient one. Every component has to earn its place.
02 — 03
1 : 0.8. Maltodextrin to fructose. Not a marketing claim — the ratio that four independent peer-reviewed studies converged on as optimal for carbohydrate absorption with minimal gastrointestinal distress.
03 — 03
By activating two separate intestinal transporters simultaneously, Solus delivers up to 90 grams of carbohydrate per hour — 50% more than single-source glucose. The ceiling lifted by science, not marketing.
The ratio that maximises carbohydrate oxidation with the lowest gastrointestinal distress. Confirmed across four independent peer-reviewed studies spanning twenty years of endurance science.

The research
The 1 : 0.8 ratio is not a Solus invention. It is the conclusion that multiple independent research teams reached — separately, consistently, over two decades. We chose it because the evidence pointed to it.
Rowlands et al. — American Journal of Physiology
Compared fructose-maltodextrin ratios of 0.5:1, 0.8:1 and 1.25:1 in cyclists over 150 minutes. The 0.8:1 ratio delivered the highest exogenous carbohydrate oxidation rate and the lowest reported stomach fullness, cramping and nausea of any ratio tested.
Highest oxidation rate.
Lowest GI distress.
Rowlands et al. — Medicine and Science in Sports and Exercise
Cyclists ingesting 0.5, 0.8 and 1.25 ratios during a 2-hour ride followed by a sprint test. The 0.8:1 ratio produced oxidation rates 18% higher than the 0.5 ratio and 5.2% higher than the 1.25 ratio.
18% higher oxidation
vs. lower ratio.
Rowlands et al. — Sports Medicine (critical review, 14 studies)
At 1.5–1.8g/min ingestion rates, ratios between 0.7:1 and 1.0:1 were absorbed fastest and conveyed the highest exogenous carbohydrate energy. The 0.8:1 ratio delivered peak performance at the threshold.
Optimal absorption
window confirmed.
Podlogar et al. — European Journal of Applied Physiology
High-dose 0.8:1 ratio (120g/hr) vs. traditional 90g/hr over 3 hours of cycling. Significantly higher exogenous carbohydrate oxidation without significant GI discomfort — validating high-dose dual-transport fuelling for serious athletes.
High-dose protocol
independently validated.
Our philosophy
Endurance nutrition has been made more complicated than it needs to be. The science of fuelling settled years ago. Two ingredients, one ratio, nothing else. We built Solus because we wanted a product that reflected that — clean, honest, and priced to be used every day. The only carbohydrate fuel you need, with only the ingredients that matter.
