Protein powder tips for beginners: the short version

Start with the protein you already eat, then compare options if you decide to add a powder. This guide explains common formats, serving sizes and price calculations, with six practical checks before buying your first tub.

1. Work out your target first. Know roughly how many grams of protein you eat now before you buy anything.
2. Buy plain, buy small. A simple whey (or pea-rice blend) in a small tub or sample size tells you whether you like the taste before you commit.
3. Read the label for protein per serving and per 100 g. Powders differ a lot; the front of the tub does not tell you.
4. Compare price per gram of protein, not per tub. The worked example in section 4 shows how.
5. Protein timing. A meta-analysis of protein-timing studies found that, once total protein intake was accounted for, timing made no significant difference (Schoenfeld, Aragon & Krieger 2013).
6. Skip the extras. A beginner does not need a stack. See the beginner supplement stack for what is worth considering.

1. What Is Protein Powder?

Protein powder is concentrated protein extracted from a food source — most commonly whey (from milk), casein (also from milk), eggs, peas, rice or soy. The water, most of the carbohydrate and much of the fat are removed, leaving a powder that mixes with liquid into a protein-dense drink.

That is all it is. There is nothing magical or pharmaceutical about it. It is protein — the same macronutrient found in chicken, eggs, Greek yoghurt and legumes — in powder form.

2. Do Beginners Actually Need Protein Powder?

No. Protein powder supplements your diet when whole-food protein is insufficient. If you are consistently eating enough complete protein from food (meat, fish, eggs, dairy, legumes, tofu), you do not need powder.

Protein powder becomes genuinely useful when:

• Your daily protein target is not reached through whole foods alone.
• You want to add protein to smoothies, oats or yoghurt without adding large amounts of fat or carbohydrate.

3. How Much Protein Do Beginners Need?

The ISSN position stand on protein and exercise puts the intake that is sufficient for most exercising people at about 1.4–2.0 grams of protein per kilogram of bodyweight per day (Jäger et al. 2017). For a 70 kg beginner that is roughly 98–140 g a day.

As reported, a 2018 meta-analysis of 49 randomised controlled trials (1,863 participants) of protein supplementation during resistance training (Morton et al. 2018) reported that, with protein supplementation, total protein intakes above about 1.6 g/kg/day did not further contribute to resistance-training-induced gains in fat-free mass. Its break-point analysis (42 study arms, 723 participants) gave 1.62 g/kg/day with a 95% confidence interval of 1.03 to 2.20 and was not statistically significant (p = 0.079). That is a finding about groups of trial participants, not a promise about any one product or person.

Before buying anything, add up what a normal day of eating already gives you (food labels and a free tracking app make this a ten-minute job); a single shake can then close a known gap rather than a guessed one. See our complete guide to daily protein requirements for the full breakdown.

4. How to Choose Your First Protein Powder: a Label Checklist

Whichever type you pick, the same five checks apply:

• Protein per serving and per 100 g. Both are on the label. A product that is 80% protein by weight and one that is 65% are very different value even at the same tub size.
• Serving size. Protein per serving is only comparable between products if the serving sizes are.
• Ingredient list. Shorter is simpler. Added thickeners, sweeteners and flavourings are not a problem in themselves, but you should know what is in your tub. Our guide to reading a supplement label covers serving sizes, blends and what label wording legally means.
• Allergens and lactose. Whey and casein come from milk. Whey isolate contains less lactose than concentrate, and a pea-rice blend avoids dairy altogether.
• Price per gram of protein. Multiply the tub weight by the protein share, then divide the price by that number. As an illustration with made-up round numbers (not a tracked price): a 1 kg tub at €30 that is 80% protein holds 800 g of protein, which is €3.75 per 100 g of protein.

To see how real listings compare, our live tables normalise retailer prices per 100 g of powder for protein powder in Malta and protein powder in Cyprus; check the protein share on the label before you rank them.

5. Which Type of Protein Powder Should a Beginner Choose?

Whey Protein (Concentrate or Isolate)

An option for beginners who are not dairy-free or vegan. Whey concentrate is cheaper; isolate costs more but has less lactose. See our whey isolate vs concentrate guide for the full comparison.

Pea and Rice Protein Blend

The best plant-based option for dairy-free or vegan beginners. A combined pea and rice blend covers the amino-acid limitations of each individual source.

Casein

The ISSN position stand (Jäger et al. 2017) describes casein as water insoluble, coagulating in the gut and digested more slowly than whey protein. Some athletes use it before sleep. It is not a first-choice product for a beginner — buy whey first, then consider casein later if you want to experiment.

6. How Much Per Serving, and When to Take It

For a single serving the ISSN position stand gives about 0.25 g of high-quality protein per kg of bodyweight, or an absolute 20–40 g, spread across the day rather than loaded into one drink (Jäger et al. 2017). For a 70 kg beginner that is about 18 g, so one standard scoop is plenty and a second scoop is not a bonus.

The “anabolic window” — the idea that you must drink protein within 30 minutes of training or the session is wasted — has been tested in studies. A meta-analysis of protein-timing studies found that, once total protein intake and other differences between studies were accounted for, timing made no significant difference, and total daily intake was the strongest predictor of the result (Schoenfeld, Aragon & Krieger 2013).

In practice: it can be taken at different times, for example after training, with breakfast, as an afternoon snack or before bed.

7. How to Mix It and What to Expect

Whey mixes well in cold water or milk with a shaker bottle; 30 seconds of shaking is generally enough, and you do not need a blender for a simple shake. Most whey products taste fine in water, though milk adds creaminess and extra protein.

Expect the shake to taste like a flavoured milk drink (chocolate, vanilla and strawberry are common). Expect the amount of protein per scoop printed on your label, in 150–250 ml of liquid. Do not expect a dessert, and do not buy a cheap product just because it promises an extreme flavour.

8. Common Beginner Mistakes

• Buying the biggest tub first. If you dislike the flavour, a large tub becomes a sunk cost. Start small.
• Ignoring food. Powder fills gaps; it does not replace meals. If most of your protein is from powder, look at the diet.
• Doubling scoops. More than the serving you need is not a head start; see the per-serving figures above.
• Paying for extras you do not need. Blends with added amino acids or “recovery” ingredients can cost more per gram of protein; compare before paying. Plain is fine to begin with.
• Treating timing as a rule. See section 6 for what the studies found on timing.

If you have a kidney condition, a milk allergy, or take medication, check with a healthcare professional before raising your protein intake or starting a supplement.

Conclusion

Protein powder is an option for beginners who struggle to reach their daily protein target through food alone. It is not necessary. Start with a straightforward whey concentrate or a plant-based pea-rice blend, read the label, compare price per gram of protein, focus on reaching your daily target consistently, and let the training do the rest.
