BioTechUSA supplements: protein, creatine and amino acids

BioTechUSA is a Hungarian sports nutrition manufacturer, founded in 1999 and based in Budapest. The range covers whey protein powders, creatine, amino acids, vitamins, bars and ready-mixed drinks. Most people meet the brand through Iso Whey Zero, its best known whey isolate, but the catalogue is far wider than that one tub. You can place it next to the other names we carry in our full brand overview.

The protein range explained

Iso Whey Zero is built on cross-flow micro- and ultra-filtered whey protein isolate. Filtration removes most of the milk sugar and fat, so the mixed shake contains less than 0.1 g lactose per 100 ml. 100% Pure Whey combines concentrate with isolate: creamier, lower in price per serving, but it still contains some lactose. Both give roughly the same protein per scoop, so your real choice is about texture, price and how you handle dairy sugar.

Three variations are worth knowing before you order:

Iso Whey Zero Clear: a light, fruity drink rather than a creamy shake. It foams, so leave it to settle for about a minute.
Iso Whey Zero Black: isolate with 3 g of micronised creatine monohydrate added per serving.
Vegan Protein: plant-based, for anyone leaving dairy out completely.

Protein contributes to the growth of muscle mass and to the maintenance of muscle mass. That is the whole job of a powder, which is why these tubs sit beside the rest of our sports protein powders rather than in a category of their own.

Beyond protein, the brand covers the usual training basics: creatine monohydrate, BCAA and EAA blends, L-carnitine drinks, gainers, gummies and single vitamins. The formats are practical: large bags for daily shake drinkers, small tubs to test a flavour first, and 25 ml shot bottles for training days away from home.

Why we stock BioTechUSA

Before a brand reaches our shelves we look at three things: the form of the ingredient, the dose, and whether the combinations make sense. BioTechUSA holds up on all three in its core lines. Isolate is used where low lactose actually matters, and Iso Whey Zero Black carries 3 g of creatine monohydrate per serving, the amount linked to high-intensity performance. We are equally clear about the rest: nearly every flavour is sweetened with sucralose, and a few use colours that carry the EU warning about activity and attention in children. We buy straight from the brand, and our compliance team checks each label before it goes live. Read how we select brands and products.

Who this range suits

It fits people who train several times a week and want a familiar, widely available protein without paying a premium price. If dairy sugar bothers you, the isolate lines are the sensible starting point. If you mostly bake with your powder or drink it with milk, 100% Pure Whey gives you more servings for your money.

One honest note: a powder is convenience, not a requirement. Most UK adults already pass the official protein reference intake through food, and a shake earns its place when your daily target is higher and meals alone make it awkward. If you train for strength and power, buying Creatine separately is usually cheaper per gram than paying for a protein with creatine built in, and it lets you keep the two doses independent.

BioTechUSA is a sports nutrition manufacturer founded in 1999, with its head office in Budapest, Hungary. Despite the name, it is a European company, and its products are made and labelled for the European market. The range now runs to several hundred product variations, sold through its own stores in a number of European countries and through retailers like us. Manufacturing and labelling follow EU food supplement rules.

The core is protein: whey isolate, concentrate and isolate blends, clear protein drinks, casein and plant-based options. Around that sit the standard training products, creatine monohydrate, BCAA and EAA powders, L-carnitine drinks and pre-workout blends, plus mass gainers for people struggling to eat enough. There is also a smaller everyday line of vitamins, minerals, collagen drinks, gummies and protein bars.

Zero refers to specific label rules, not to the powder in the bag. The values apply to the drink once you mix it with water. Sugar-free means less than 0.5 g of sugar per 100 ml of the mixed drink, lactose-free means less than 0.1 g of lactose per 100 ml, and gluten-free follows EU legislation. So a small amount can still be present, just below the legal threshold. That matters if you are very sensitive.

UK guidance sets a reference nutrient intake based on body weight, and it is a minimum to avoid a shortfall, not a training target. Most adults here already reach it through food. People who train hard, are cutting calories or are over 60 often aim higher, spread over three or four meals rather than in one large shake.

Group	Protein per day
Adults (per kg body weight)	0.75 g
Adult women (average)	45 g
Adult men (average)	56 g

Total daily protein matters more than the clock. A shake after training is convenient because it is quick and easy to drink when you have no appetite for a meal. Isolate mixes thin, so it sits lightly. Just as valid is using it between meals, in porridge or in yoghurt, on days when hitting your target with food alone is inconvenient. Pick the slot you will actually keep to.

The Iso Whey Zero lines are whey isolate with less than 0.1 g of lactose per 100 ml in the mixed drink, so most people with lactose intolerance tolerate them well. They are still dairy, so they are not vegan. For a fully plant-based option, choose Vegan Protein. Note that the powders are made in a plant that also handles milk, egg, soy, nuts, crustaceans and sulphur dioxide, which matters if you have a severe allergy.

Yes, and this is worth reading before you buy. Most flavours use sucralose as the sweetener, which is what gives the range its sweet, sometimes noticeably artificial taste. Several fruit flavours also use colours such as tartrazine or Allura red, which carry the EU statement that they may have an adverse effect on activity and attention in children. If you avoid these, check the ingredient list of the specific flavour, since formulations vary between flavours.

It depends on how precise you want to be. Iso Whey Zero Black includes 3 g of creatine monohydrate per serving, the daily amount linked to increased physical performance in successive bursts of short-term, high-intensity exercise in adults doing that kind of training. Convenient, but you only get the creatine when you drink the shake. A separate tub of creatine is usually cheaper per gram, works on rest days too, and pairs easily with pre-workout formulas. Expect a few weeks of daily use before muscle stores are full.
