Introduction
The world of supplements can be confusing. Beyond protein powders, you’ll find shakes, bars, ready-to-drink products, and add‑ons like amino acids and creatine.
This guide explains the main types of protein-related supplements you’ll see on Amazon.co.uk, the key factors to look out for, and how we approach them at Protein Pitstop.
Protein Powders
Protein powders remain the most common supplement type. Options include whey, casein, plant‑based varieties (like pea, soy, or hemp), and blended formulations. Each has different digestion speeds and dietary suitability.
Tip: Always check the product label for protein content per serving and avoid unnecessary additives if you prefer cleaner formulations.
Ready‑to‑Drink (RTD) Shakes
Ready-to-drink shakes are popular for their convenience — they’re pre‑mixed, portable, and portion‑controlled. However, they often cost more per serving compared to powders.
Tip: Check the nutrition labels closely. Some RTDs contain added sugars or provide fewer grams of protein than powders, so it’s worth comparing carefully.
Protein Bars & Snacks
Protein bars and snacks combine taste with convenience, but vary widely in quality. Some deliver a high protein content, while others are closer to regular confectionery with extra protein added.
Tip: Compare protein content per bar, not just the calories, and check sugar and fibre levels if those are important to you.
Other Common Supplements
Alongside protein-focused products, you may also come across:
- Creatine – one of the most widely researched sports supplements, sometimes included in blends.
- BCAAs (Branched Chain Amino Acids) – marketed for recovery, though many people get sufficient amounts from a balanced diet.
- Meal replacement shakes – higher calorie blends with protein, carbs, and fats for convenience.
Note: At Protein Pitstop, we only cover these where they overlap with protein-focused products available on Amazon.co.uk.
