Pros and cons
Pros
- Range covers whey protein, creatine, pre-workout and meal-replacement, so a training stack can stay in one place (whey protein, creatine and pre workout).
- Support runs on email, phone and help centre, which is a wider set of routes than a store working by email alone.
- The line-up reaches further than HUM Nutrition, which lists plant protein and creatine and no pre-workout or meal-replacement options.
- Prices start lower than the top end of the protein powder field, with entry points at €3.67 to €56.99.
- Per-serving costs at €1.04 to €1.67 sit in line with the 48 brands in protein powders.
Cons
- Prices are listed as one-off product prices, so there is no separate renewal price to weigh for repeat orders (whey protein, creatine and pre workout).
- The product mix misses electrolytes, bars and mass gainers, which Body Attack adds to whey protein, plant protein and creatine.
- Protein content per serving is thinner at the lower end than meal replacement shakes, where the range starts at 18.
Who it suits
- Lifter stocking whey protein, creatine and pre-workout from one store (whey protein, creatine and pre workout).
- Buyer who wants phone help alongside email and a help centre (email, phone and help centre).
- Someone comparing per-serving spend in the protein powder field (€1.37).
Who should look elsewhere
- Plant protein buyers, since whey protein, creatine and pre workout and plant protein and creatine cover different bases and HUM Nutrition leads on plant protein.
- Anyone after bars, electrolytes or mass gainers, which appear in whey protein, plant protein and creatine but not in whey protein, creatine and pre workout.
The company behind it
i-Supplements trades as i-Supplements and is based in the United States, so the store is set up for buyers in that market rather than a single country elsewhere. The product side covers whey protein, creatine and pre workout, which is broad enough to cover a full training stack and a shake used in place of a meal, without plant protein at the core of the range. Help is offered on email, phone and help centre, meaning questions can go by email, by phone or through a help centre rather than waiting on a form. That mix of contact routes is worth weighing if a product question or a delivery query needs sorting out.
How i-Supplements compares
Frequently asked questions
What does i-Supplements sell?+
The catalogue runs to whey protein, creatine and pre workout. That covers a protein staple, a creatine product, a pre-workout and a meal-replacement shake, so a training stack can be built without moving between stores. Plant options are not the focus of this range.
How much does protein cost per serving?+
In the protein powder field, per-serving costs run €1.04 to €1.67, with a median of €1.37. Those figures sit in the same band as the 48 brands compared, so the choice is about protein per serving rather than price alone.
What is the entry price?+
Entry prices in the protein powder category run €3.67 to €56.99. For creatine and pre-workout the range is €5.93 to €47.38, and meal replacement shakes sit at €3.67 to €38.84.
How much protein is in each serving?+
Protein per serving runs 15 to 40 g in the protein powder field, with a median of 24 g. Meal replacement shakes are comparable at 18 to 44 g.
Where is i-Supplements based?+
The company trades as i-Supplements and is based in the United States. That sets the market the store is built for, and it is worth checking against the market you shop from before ordering.
How can I contact the company?+
Support runs on email, phone and help centre. You can email, ring a phone line or work through the help centre, which is more choice than stores that answer by email only. A phone line is useful for anything urgent around an order.
Does the range include plant protein?+
Not in the core line, which covers whey protein, creatine and pre workout. For plant protein, plant protein and creatine and the plant entry in whey protein, plant protein and creatine are the places to look. Anyone avoiding dairy protein should compare those options directly.
How do the prices compare with other creatine and pre-workout sellers?+
Per-serving costs here fall between €0.66 and €1.66, against a field median of €1.32. Across 56 brands, that places i-Supplements in the middle of the pack.
