Is Reflex Nutrition a good brand?
Reflex Nutrition is a quality-first British brand known for Micellar Whey (an undenatured whey and casein blend), One Whey and Native Whey. It adds Digezyme digestive enzymes to several products and runs batches through informed testing, which is why it sits at the mid-to-premium end rather than the budget bracket. WheyWise tracks 10 Reflex products. The cheapest is £0.63 per 25g of protein on Complete Diet Protein 600g, ranging up to £1.37. Worth it if ingredient quality and mixability matter more to you than the lowest possible price.

About Reflex Nutrition

Frequently Asked Questions
How much does Reflex Nutrition protein cost in the UK?
Reflex currently ranges from £0.63 to £1.37 per 25g of protein across UK retailers we track, with Complete Diet Protein 600g the cheapest right now. Every price is shown with the date it was checked.
Is Reflex Micellar Whey a slow or fast protein?
Micellar Whey blends whey (fast) with micellar casein (slow), so it releases amino acids over a longer window than a pure whey. That makes it a flexible all-day option rather than a strictly post-workout powder.
Is Reflex Nutrition worth the extra cost?
Reflex prices above budget concentrate because of the added enzymes, batch testing and blend quality. If you want the lowest cost per gram of protein, plain whey concentrate is cheaper; if mixability, digestion and tested quality matter to you, Reflex earns its place. The table above shows exactly how much extra you pay per 25g.

Methodology
How we rank every bag.
Independent and transparent, with every price shown alongside the date it was checked. Here's what goes into each score.
01
Cost normalised to £/25g
Every bag divided by its true protein weight, so you see the real cost of a scoop across any size or brand.
02
Protein density, measured
Protein per 100g from the product's own nutrition panel, so a 90% isolate and a 72% concentrate are never compared on bag price alone.
03
Every price carries its date
Prices come from the retailer's own listing, never an RRP, and each one is shown with the day it was last checked so you can judge how current it is.
04
No sponsored placements
Rank order is cost per 25g of protein. Some outbound links earn commission; none of them buy a position in the table.
