FAQs
How do I choose between isolate, concentrate, and blends?
It depends on your goals, diet, and tolerance to dairy:
- Highest protein content (usually 90%+)
- Very low in carbs, fats, and lactose
- Great for lean muscle gain or anyone sensitive to lactose
Whey Protein Concentrate (WPC):
- Slightly lower protein percentage (around 75–80%)
- Contains more lactose, carbs, and healthy fats
- A budget-friendly option that still supports muscle growth and recovery
Protein Blends:
- Combine fast and slow-digesting proteins (e.g. whey + casein, or multi-plant blends)
- Provide a more sustained release of amino acids
- Useful for satiety, recovery across the day, and meal replacement
In short:
- Choose isolate if you want the leanest option or are lactose-sensitive.
- Choose concentrate if you want a cost-effective all-rounder.
- Choose a blend if you want balanced nutrition and longer-lasting recovery.

Which protein has the least lactose?
If you’re sensitive to lactose, here’s how protein powders compare:
- Whey Protein Isolate (WPI): Contains the lowest lactose of all dairy-based proteins, as most of the lactose is filtered out during processing.
- Plant-based proteins (like pea, rice, or fava bean): Naturally lactose-free, making them ideal for dairy-free diets.
- Marine or bovine collagen: Also completely lactose-free.
So if you want to keep lactose to a minimum, whey isolate is the best dairy option, while plant-based proteins and collagen are 100% free from lactose.

What’s a good supplement stack for muscle gain?
A solid muscle gain stack usually includes:
- Protein powder – helps you hit daily protein targets to support muscle repair and growth
- Creatine – boosts strength, power, and workout performance
- Recovery support – such as EAAs or a post workout blend to aid repair and reduce muscle soreness
- BCAAs – can be useful if you’re training intensely or in a calorie deficit to help preserve muscle
The best stack depends on your goals, training intensity, and diet. Supplements work best alongside a balanced nutrition plan and consistent strength training.

Should I take creatine before or after lifting?
Creatine can be taken at any time of day, as long as you’re consistent.
That said, many athletes prefer to take creatine post workout, often with a protein shake or carbohydrate source, as this may help with absorption and is convenient after training. Others simply take it at the same time each day (morning, pre workout, or post workout).
What are the top 3 products to start with?
For most beginners, a simple stack is the best place to start. Three core supplements to consider are:
- Protein powder – helps you hit your daily protein target to support muscle repair, recovery, and overall nutrition.
- Creatine – one of the most researched supplements for improving strength, power, and workout performance.
- Greens powder or a multivitamin – helps fill nutritional gaps and supports general health and wellness.
These products cover the basics: performance, recovery, and everyday nutrition — a solid foundation before exploring more specialised supplements.
What’s the difference between BCAAs and EAAs?
Both BCAAs and EAAs play a role in muscle recovery, but they’re not the same:
- BCAAs (Branched-Chain Amino Acids): Made up of three essential amino acids — leucine, isoleucine, and valine. These are especially important for muscle repair, reducing soreness, and supporting exercise performance.
- EAAs (Essential Amino Acids): Include all nine essential amino acids your body can’t produce on its own. EAAs offer a more complete profile for muscle growth, recovery, and overall protein synthesis.
In short, BCAAs are a subset of EAAs. If you want comprehensive support for muscle building and recovery, EAAs provide broader benefits, while BCAAs can still be useful during training for targeted recovery support.
