As a Nutrition Coach at CrossFit Chiltern, I’m often asked about supplements. The wellness market is flooded with products, each promising incredible benefits – from boosting energy and burning fat to improving sleep and enhancing performance. For people trying to do their best for their family’s health, this can be incredibly confusing. Do you need them? Which ones? Are they truly effective?
My stance, and a core principle within our Ignite Nutrition Programme, is clear and evidence-based: Choose whole foods over supplements! Whole foods are the ideal way to receive vitamins & minerals due to their superior bioavailability and absorption rates. While supplements can certainly play a role, they are meant to supplement a healthy diet, not replace it.
Why Whole Foods Come First (Always!)
The reason whole foods are superior is simple: they offer a complex synergy of nutrients – vitamins, minerals, fibre, antioxidants, and countless other compounds – that work together in ways isolated pills cannot replicate. Taking many different vitamins & minerals in pill form is generally not recommended as the body is designed to absorb and utilise nutrients most effectively when they come from real, unprocessed food.
So, when are supplements actually recommended? Supplements are recommended when your intake isn’t enough to cover your needs. This means they fill specific nutritional gaps that can’t easily be met through diet alone, or address a diagnosed deficiency. If lab work results show you are low in something, this would be a good reason to consider a supplement. This highlights why annual health screenings and blood work are recommended for tracking trends.
Key Supplements: What to Consider (and What to Skip)
While the market is vast, a few key supplements are generally well-researched and can be beneficial when used appropriately.
1. Omega-3 Fatty Acids (The Anti-Inflammatory Hero)
- Why they’re important: Omega-3 fatty acids play an important role in the body by decreasing inflammation & recovery time, as well as improving heart health and mood.
- What to look for: Be mindful that Omega 6s & 9s can increase inflammation. While we need some, we don’t typically need to add additional sources through supplementation. When taking an omega supplement, you generally want to focus on Omega 3s (look for DHA or EPA on the label). Aim for a high-quality fish oil supplement.
- Whole food sources: Fatty fish like salmon, mackerel, and sardines.
2. Protein Powders (Your Convenient Protein Boost)
Protein powders are not a replacement for whole food protein, but they can be incredibly useful for busy individuals or those with higher protein needs (e.g., active CrossFit athletes) who struggle to meet their intake goals through food alone.
- Whey Protein: This is considered a gold standard for building lean muscle mass. It’s fast-absorbing & often best to have post-workout.
- Pea Protein: A great vegetarian and dairy-free option. Unlike some plant-based protein powders, it is well digested & highly bioavailable. Pea protein is almost as effective as whey protein for building muscle, feeling satiated, & recovering from workouts.
- Casein Protein: A good option for athletes looking to build muscle but are not meeting their protein goals for the day. Casein is slow digesting & is often recommended to have at night.
- Collagen Protein: Collagen protein has been shown to have benefits for hair, skin, nails & joints. However, it is not a complete protein so you shouldn’t take it in place of your post-workout protein powder.
3. Creatine Monohydrate (Beyond Just Muscle)
Creatine is one of the most well-researched supplements available, often associated with strength and power athletes, but its benefits extend far beyond just muscle.
- Why it’s important: Creatine helps your body produce energy rapidly during high-intensity, short-burst activities (like lifting weights or sprinting). It can enhance strength, power, and muscle growth.
- Emerging Research: Beyond its well-known physical benefits, research is increasingly exploring creatine’s potential positive impacts on brain function (e.g., memory, cognitive processing), mood, and even certain neurological conditions. It plays a role in cellular energy in various tissues, not just muscle.
- What to look for: Creatine monohydrate is the most studied and effective form. It’s generally safe for most healthy individuals when taken at recommended dosages.
- Whole food sources: Small amounts are found in red meat and fish.
What to Be Wary Of:
Be skeptical of products promising miracle cures or rapid results. Always consult with a healthcare professional before starting any new supplement, especially if you have existing health conditions or are taking medications.
A specific word of caution: Be particularly wary of creatine gummies. Recent findings have shown that some brands, even those that publish test data, have been found to contain zero trace of actual creatine. Always opt for reputable, third-party tested powders or capsules from trusted brands to ensure you’re getting what you pay for.
