Huel’s own made comparison vs Soylent
My thoughts:
Soylent is lower in proteins, they use soy protein isolate only (which likely equates to have less well rounded amino acid profile). Soylent is also higher in fats and saturated fats. Soylent also has more sugars (but still below the the recommended) and uses maltodextrin (high GI) isomaltulose combo.
Shake wise the rtd is smoother but has a strong soy taste.
Huel vs Jimmyjoy (another EU brand available in US)
Jimmyjoy is cheaper and offers thinner shakes than Huel. However, all Plenny Shakes (except Active) are quite low in protein, higher than Huel in carbs (contains maltodextrin).
Taste wise Jimmyjoy offers more pre-mixed variety and their chocolate is fairly good. Shakes are thinner and smaller (less water needed). However, if left overnight they take a jelly like consistency. I like the Huel Vanilla better because it is a more natural, stronger flavour.
vs Queal (another Dutch company available in the US)
Queal tends to have more pre-mixed flavours and offers a light, athletic and standard version, as well as, a vegan shake.
Queal’s shakes are usually larger (larger serving size) have similar amount of protein but less fats and more carbs. They use whey protein in all except the vegan option.
The shakes tend to be thin and the flavours pretty spot on.
vs Pulve. (Article comparing both in detail: https://latestfuels.com/david-vs-goliath/the-best-european-vegan-shake/)
This is a brand that is very similar to Huel in most aspects. It is EU sourced and produced and contains no soy. Otherwise, nutritionally is very similar to Huel.
Even taste wise and consistency wise is very similar, thick grainny and strong vanilla flavour.
Overall Huel faces very well vs most competitors (there are so many more out there). Huel does not offer an organic shake, so you would have to go for something like Ample or Ambronite; or a keto shake (Sated, Ketochow); or a soy free shake, Pulve; or a thin shake; or a carb heavy shake. Those would be the main reasons (besides price, convenience or specific taste) to choose another shake. Otherwise, Huel tends to be victorious in most 1v1s.
