The question people ask most before buying protein powder for the first time is which one should I choose? The answer does not depend on which is best overall. It depends on three things — what your body digests well, what your goal is, and what your monthly budget is.
The short version
- Whey isolate has the highest leucine. Best for lifters who want the clearest result.
- Egg white for people who react to dairy. Hydrolysed chicken for those who react to both dairy and egg.
- Plant protein should be a blend of several sources, not one.
- Compare price per gram of protein, not per tub.
0.8–1.0 g/kg/day for general adults
1.6–2.2 g/kg/day for people training with weights consistently
The comparison at a glance
| Type | Source | Absorption | Lactose | Who it suits |
|---|---|---|---|---|
| Whey isolate | Cow's milk | Fastest (1–2 h) | Almost none | Lifters who want high leucine |
| Egg white | Chicken egg | Moderate | None | People who react to dairy but tolerate egg |
| Hydrolysed chicken | Chicken breast | Fast (pre-digested) | None | People who react to both dairy and egg |
| Plant protein | Pea, rice, seeds | Slightly slower | None | Vegan and vegetarian diets |
01 Whey protein isolate
Whey comes from the liquid left over in cheese making. There are three grades by purity — concentrate (WPC) at roughly 70–80% protein with meaningful lactose and fat left in; isolate (WPI) at 90% and above, with almost all lactose and fat filtered out; and hydrolysate (WPH), already broken into peptides and the most expensive.
Whey's strength is leucine, the amino acid that acts as the main signal for muscle protein synthesis. Gram for gram, whey contains clearly more of it than plant protein.
Bloated on whey? Do not write whey off yet. A great many people digest lactose poorly and get bloating or gas from whey concentrate. Switching to isolate, with almost all the lactose filtered out, usually resolves it. Try isolate before deciding.
02 Egg white protein
Egg white protein is albumin dried into a powder. No lactose at all, and a very high protein quality score — egg white was once the reference standard for measuring food protein quality.
It digests a little slower than whey, which is not always a disadvantage. Anyone drinking it before bed or during the day for satiety benefits from the slower digestion. The limitations are taste and smell, which some people dislike, and a fluffier texture than whey.
03 Hydrolysed chicken protein
Still little known, but it solves a specific problem precisely — for people who react to both dairy and egg and do not want plant protein because of amino acid completeness. Hydrolysed chicken protein is animal protein broken down enzymatically into short peptides, so it absorbs quickly and delivers the complete amino acid profile of an animal source.
04 Plant protein
Each plant protein is short on a different amino acid — pea protein is low in methionine, rice protein is low in lysine. Blending two sources fills in the profile. That is why a good plant formula blends several sources rather than using one.
- Pea protein isolate — the highest protein content in the plant group.
- Organic rice protein — the easiest to digest and least allergenic, good for sensitive stomachs.
- Clear pea protein peptide — a juice-like texture, not thick, easy to drink through the day.
- Seed proteins — chia, pumpkin, sunflower, flax, watermelon and almond, giving protein, fibre and minerals together.
05 Working out how much you need
An adult who does not train hard needs around 0.8–1.0 g per kg of body weight per day. Sports nutrition guidance for people lifting consistently is 1.6–2.2 g per kg per day.
A worked example. Someone weighing 60 kg training 3–4 days a week needs roughly 96–132 g a day. If normal meals provide about 70 g, the gap is 30–60 g — one to two scoops of protein powder a day, not four or five.
06 The right way to compare price
Do not compare price per tub. Compare price per gram of protein: price ÷ (net weight × protein percentage on the label).
| Example | Tub A | Tub B |
|---|---|---|
| Price | $30 | $21 |
| Weight | 1,000 g | 500 g |
| Protein on label | 80% | 70% |
| Price per gram of protein | $0.0375 | $0.06 |
The tub with the lower sticker price is almost twice as expensive in practice.
Frequently asked questions
When is the best time to drink protein?
- Current research says total daily protein matters far more than timing. The “anabolic window” once believed to be 30 minutes after training is much wider than that.
Will protein make women bulky?
- No. Adding muscle mass requires consistent resistance training plus an energy surplus. Drinking protein alone does not do it.
Can I take protein if I do not train?
- Yes. Protein powder is food, not medicine. Use it to top up on days when meals fall short.
Can I mix plant protein and whey?
- Yes, and many people do it to cut cost while keeping enough leucine — whey as the base, plant protein to add volume.
