SCI-MX V-Gain vs Ultra Plant Protein
If you've been looking on our site for a vegan protein supplement recently, you'll have clocked we stock two SCI-MX plant proteins, V-Gain and Ultra Plant Protein. Both are Vegetarian Society-approved, dairy-free, and made right here in the UK. Beyond that, they're built for slightly different priorities and benefits.
V-Gain is a performance blend; protein plus slow-release carbs, designed to fuel training as well as recovery from it. Ultra Plant Protein is a leaner, faster-digesting formula focused purely on getting quality protein in, with digestive enzymes to keep things comfortable for those with a sensitive stomach.
SCI-MX V-Gain: slow-release energy
V-Gain's protein complex is a blend of soy, pea, and brown rice isolates (39g per 45g serving), giving you a complete amino acid profile without relying on just one single plant source.
What sets it apart is ModCarb™ a complex carb blend made from oat bran, quinoa, amaranth, buckwheat and millet. That means you're not just getting protein, you're getting a steady release of energy alongside it; no quick spike and crash. If you're training hard, bulking, or just struggling to hit your calories on a plant-based diet, this extra fuel matters.
It also provides solid support with added Arginine AKG, magnesium, zinc, B6 and B12; the last two being nutrients vegans commonly run low on.
SCI-MX Ultra Plant Protein: lean and easy to digest
Ultra Plant is soy-free, built instead from pea protein isolate, hydrolysed pea protein isolate, and rice protein (33g per 45g serving). The hydrolysed pea protein derserves a shout out; it's been broken down further before you even drink it, which generally means faster, more comfortable, absorption.
It's also stacked with BCAAs and leucine; leucine being the amino acid that does most of the heavy lifting in triggering muscle protein synthesis, so it's goimng to make a genuine difference to your post-workout recovery.
Plant proteins can sit heavy on the stomach for some people, so SCI-MX has added DigeZyme® to its Ultra Plant protein. DigeZyme® is a complex composed of five key digestive enzymes; alpha-amylase, protease, lipase, cellulase, and lactase and helps break down carbohydrates, proteins, fats, fibre, and dairy sugars for better nutrient absorption. You'll also get your hit of magnesium, zinc and a B-vitamin complex, all of which support normal energy metabolism.
So, which vegan protein is the one for me?
If you're after a proper all-in-one that fuels the session as well as feeds recovery (and you're not fussed about soy), SCI-MX V-Gain is your one. Chuck it in a shaker pre or post-training and you've got protein and slow-burn carbs sorted in one go.
If you want a leaner, purely protein-focused shake that digests easily and skips the soy altogether , SCI-MX Ultra Plant Protein is a better bet.
Is vegan protein actually as good as whey?
On paper, whey has a natural edge. It's a fast-absorbing, naturally complete protein with a high leucine content (and leucine is the amino acid that does most of the work in triggering muscle protein synthesis). Single plant proteins on their own don't quite match this. Pea protein runs a bit low on methionine, rice protein runs a bit low on lysine, used alone, neither is a perfect match for whey.
However, SCI-MX has solved this issue by blending multiple plant sources together so the amino acid gaps in one are covered by the others. Soy, pea and brown rice in V-Gain; pea, hydrolysed pea and rice in Ultra Plant. Blended properly, you end up with a complete amino acid profile that stands toe-to-toe with whey.
Mind the (leucine) gap!
Then there's the leucine gap, the bit that actually matters most for muscle growth. Both V-Gain and Ultra Plant are fortified with added leucine to close this gap and bring it in line with what you would have in a quality whey.
Digestion's the other difference; whey isolate is famously quick to absorb, plant proteins are naturally a touch slower. Both V-Gain and Ultra Plant tackle that with DigeZyme® digestive enzymes, and Ultra Plant goes a step further by using hydrolysed pea protein, which is pre-broken-down before it even reaches you, speeding absorption up and easing any bloating that plant proteins can sometimes cause.
The verdict?
A cheap, single-source plant protein won't ever match whey. But a properly blended, leucine-dosed, enzyme-supported formula like V-Gain or Ultra Plant is a genuine match for muscle growth and recovery. You're not settling for "Oh well it's good enough for the vegans", you're getting a formula engineered to deliver the same results as whey, minus the dairy.
So whether you're plant-based by choice, by necessity, or just fancy giving your gut a break from dairy for a bit; you're not going to leave any gains on the table.
