Supplements Guide
The supplement industry is enormous, but only a handful of products have strong scientific support. Save your money by focusing on what works. Always consult a professional before starting any supplement.
Well-supported basics
- Protein powder — convenient way to hit protein targets
- Creatine — among the most researched for strength and muscle
- Vitamin D — useful if you're deficient or get little sun
Situational
Omega-3s, magnesium, and others may help depending on your diet and needs. A blood test can reveal actual deficiencies.
Mostly hype
Many "fat burners" and exotic blends lack evidence. Be skeptical of bold claims and proprietary formulas.
Food first
Supplements fill gaps — they don't replace a solid diet. Nail your nutrition basics first.
If a supplement sounds too good to be true, it usually is.
Supplements support, they do not replace
Supplements are meant to fill genuine gaps in an otherwise balanced diet, not to substitute for real food. No pill or powder can compensate for consistently poor eating, and the vast majority of your nutrition should come from whole foods. Before spending money on supplements, it is worth examining whether your diet, sleep, and training are already in order, because those fundamentals deliver far more benefit than most supplements.
Which supplements have real evidence
A small number of supplements are well supported for specific situations, such as protein powder for convenience when whole-food protein is hard to reach, creatine for strength training, and vitamin D where sunlight exposure is limited. Many other products carry bold marketing claims with little robust evidence behind them. Being skeptical and researching the actual research saves both money and disappointment.
Cover the basics first
Make sure your foundation is solid using our protein calculator, calorie calculator, and healthy eating basics before considering supplements. Food first, supplements second.
Food first, supplements second
Supplements are exactly that, a supplement to a good diet rather than a replacement for one. No pill or powder can compensate for consistently poor eating, and whole foods provide a complex mix of nutrients and fibre that isolated supplements cannot match. The wisest approach is to build a solid foundation of nourishing meals first, then consider whether a specific supplement fills a genuine gap in your particular diet or circumstances.
Supplements worth considering
A few supplements have solid evidence behind them for the right person. Protein powder is a convenient way to meet protein targets, creatine is well supported for strength training, and vitamin D can help those with limited sun exposure. Beyond these, many products offer little proven benefit. Before adding any supplement, especially if you have a health condition or take medication, it is sensible to consult a qualified professional rather than relying on marketing claims.
