Choosing supplements for muscle growth and recovery
Muscle growth starts with training and total protein
Muscles grow when you train against resistance and then give your body the material to rebuild. Protein delivers that material: it contributes to the growth and the maintenance of muscle mass. What counts is your total intake across the day, not one shake straight after the gym. Most UK adults already reach the reference intake of 0.75 g per kilo of body weight from food alone. If you train three or more times a week, or eat little meat and dairy, a protein powder is simply a convenient top-up.
Form and dose decide whether a product does anything
This is where products separate. Creatine only works at a real dose: studies use 3 g a day, every day, and creatine as monohydrate has the longest research record. Many gummies and blends deliver well under that per serving, so read the label. Magnesium contributes to normal muscle function, but the oxide form is absorbed poorly next to citrate or bisglycinate. Vitamin D3 contributes to the maintenance of normal muscle function.
- Powder: lowest price per serving, easy to mix into a drink
- Capsules: no taste, expect several per serving
- Gummies: pleasant to take, check how many make a full dose
Protein type matters less than labels suggest. Whey digests fast and is high in leucine, the amino acid that switches on muscle building. A blend of pea and rice protein reaches a complete amino acid profile, so plant-based training works just as well when the daily total is right. Casein digests slowly and suits an evening serving. Choose on lactose tolerance, taste and price per 20 g of protein.
How we choose what goes in this collection
We judge every product on three things: the form, the dose and whether the combination makes sense. So we stock creatine monohydrate rather than exotic variants that cost more without better evidence, protein powders that state their amino acid content, and magnesium in well-absorbed forms. We leave out "anabolic" blends built on a long list of underdosed extras. We buy directly from the brands, our compliance team checks every label before it goes live, and independent labs spot-check batches. You can read how we select brands and products.
Honest expectations and who this suits
No supplement builds muscle on its own. Creatine needs about three to four weeks of daily use before your muscles are saturated, and the change shows up in your sets, not on the scales. Protein only helps once your total intake is high enough. Beyond that, sleep and steady training do more than anything on this page.
This collection suits people doing strength training, and equally people who want to keep the muscle they already have. From around 50, muscle mass drops faster, so resistance training with enough protein at every meal becomes more important. If your main concern is the day after a hard session, our post-workout formulas are the logical next step.
Frequently asked questions
What do muscle building supplements actually do?
They cover the gaps around your training, nothing more. Protein contributes to the growth and the maintenance of muscle mass. Creatine increases physical performance in successive bursts of short-term, high intensity exercise. Magnesium contributes to normal muscle function. That is the honest scope. The training itself, enough calories and enough sleep do the heavy work. Supplements mainly make it easier to hit your protein target and to keep training at the same quality week after week.
How much protein do I need each day?
The UK reference intake is a baseline for general health, not a target for lifters. People who train regularly usually sit above it, and average UK intakes are already higher than the reference. Use the figures below as a starting point, then check what your own meals add up to before adding a shake.
| Situation | Protein reference |
|---|---|
| Adults, per kg body weight | 0.75 g per day |
| Woman of 60 kg | about 45 g per day |
| Man of 75 kg | about 55 g per day |
| Food label reference intake | 50 g per day |
Which form should I choose?
Pick on how you will actually use it every day, because consistency decides the result. Powder is the cheapest and easiest to dose, capsules travel well, gummies suit people who dislike shakes.
| Form | Practical points | Suits |
|---|---|---|
| Creatine monohydrate powder | Lowest cost per serving, mixes into any drink | Daily use at home |
| Creatine capsules | No taste, several per serving | Travel and gym bag |
| Creatine gummies | Easy to take, dose often low | People who dislike powder |
| Whey isolate | Low in lactose, fast digesting | Sensitive stomachs |
| Pea and rice blend | Complete amino acid profile | Plant-based diets |
When is the best time to take protein and creatine?
Your daily total matters more than the clock. Spreading protein over three or four meals of roughly 20 to 30 g each is easier on your appetite than one large shake. Creatine works through saturation of the muscle, so the time of day is not important. Take 3 g every day, including rest days, with a meal or a drink. If you miss a day, just carry on, there is no need to start again.
How long before I notice a difference?
Think in weeks, not days. Creatine needs roughly three to four weeks of daily use at 3 g before your stores are full. Some people load with a higher dose for a week to get there faster, which works but is not necessary. Extra protein shows itself through training progress over one to three months. If nothing shifts, look at your programme, your sleep and your calories before buying another product.
Does creatine cause bloating or water retention?
Creatine draws a small amount of water into the muscle cell, so the scales can rise by half a kilo to a kilo in the first weeks. That water sits inside the muscle, not under the skin. Stomach discomfort is usually a dosing issue rather than the ingredient. Three to five grams in plenty of liquid, taken with food, sits better for most people than 20 g in one go during a loading week.
Can I build muscle on a plant-based diet?
Yes. Muscle building depends on your total protein and on leucine, not on whether the protein came from an animal. Single plant proteins can be low in one amino acid, so choose a blend, usually pea with rice, which covers the full profile. Serve slightly larger portions than with whey, because plant proteins carry a little less leucine per gram. The leucine content per serving is worth checking on the label.
Which supplements matter most for keeping muscle after 50?
Two things carry most of the weight: resistance training twice a week and enough protein at every meal, since the body responds less strongly to protein with age. Vitamin D contributes to the maintenance of normal muscle function, and UK sunlight is too weak from October to March, so the NHS advises a daily 10 microgram supplement in those months. You can find our range of vitamin D3 here. EFSA has also assessed creatine at 3 g a day combined with regular resistance training in adults over 55 favourably.
