In today’s world, the topic of supplements has become more mainstream than ever before, with people from all walks of life turning to supplements to support their physical and mental health. From improving sleep quality and boosting focus to enhancing hormone function, supplements are now seen as a vital tool to help maintain and improve overall well-being.
However, navigating the vast world of supplements can be daunting, especially when considering the range of options available and their specific uses. This guide aims to provide a clear, science-based approach to supplementation, explaining how to determine which supplements are right for you and how they can fit into your overall health plan.
Understanding Supplements
Supplements are often thought of as a substitute for nutrients that can be obtained from food. However, this is not always the case. While some supplements do compensate for dietary deficiencies, many others contain compounds not easily found in food, but which can play a key role in enhancing certain aspects of health such as sleep, hormone balance, and mental focus.
Supplements can generally be divided into two categories: foundational supplements, which act as a safeguard against potential nutrient deficiencies, and targeted supplements, which are used to achieve specific health outcomes. In this guide, we will explore both of these categories and offer advice on how to integrate supplements into a healthy lifestyle.
The Importance of Behavioural Tools and Nutrition
Before delving into specific supplements, it is essential to acknowledge the importance of behavioural tools and nutrition. Supplements should not be viewed as a replacement for healthy lifestyle habits, but rather as a complement to them.
Certain behaviours, such as getting adequate sunlight exposure in the morning and maintaining a regular exercise routine, form the foundation of good mental and physical health. These simple, everyday actions can have profound effects on well-being. For example, getting morning sunlight helps regulate circadian rhythms, which are critical for good sleep and mental clarity. Meanwhile, exercise supports cardiovascular health, boosts mood, and helps maintain a healthy body weight.
Nutrition plays a similarly foundational role in health. Regardless of the supplements one takes, no amount of supplementation can fully compensate for a poor diet. Proper nutrition provides the body with essential macronutrients (carbohydrates, fats, and proteins) as well as vital micronutrients (vitamins and minerals) needed to support energy, growth, and overall well-being.
Once a solid foundation of good lifestyle habits and nutrition has been established, supplements can be considered as an additional tool to enhance specific areas of health.
Foundational Supplements
Foundational supplements are intended to fill potential gaps in one’s diet. Even with the best intentions, many people struggle to consistently consume a diet that includes all the necessary vitamins, minerals, and nutrients. Factors such as busy schedules, food availability, and dietary preferences (e.g., vegetarian or vegan diets) can sometimes lead to nutrient deficiencies.
Foundational supplements often include multivitamins that provide key nutrients such as vitamins C, D, and E, as well as important minerals like magnesium and zinc. These supplements serve as a safety net, ensuring that the body has access to the essential building blocks it needs to function properly.
When it comes to foundational supplements, quality is key. While there are countless multivitamin products on the market, not all are created equal. Look for supplements from reputable manufacturers that provide clear information on ingredient sourcing and dosages. Some supplements, particularly those containing fat-soluble vitamins (such as vitamins A, D, and E), should be taken with food to ensure proper absorption.
Water-Soluble vs. Fat-Soluble Vitamins
Understanding the difference between water-soluble and fat-soluble vitamins is crucial when choosing supplements. Water-soluble vitamins, such as vitamin C and the B-vitamins, dissolve in water and are not stored in the body for long periods. As a result, they need to be consumed regularly, either through diet or supplements, and excess amounts are excreted in urine.
In contrast, fat-soluble vitamins are stored in the body’s fatty tissues and liver, which means they can accumulate over time. These vitamins include A, D, E, and K. While fat-soluble vitamins are essential for health, taking them in excessive amounts can lead to toxicity. For this reason, it’s important to avoid over-supplementation of fat-soluble vitamins and to consult a healthcare provider if you’re unsure about appropriate dosages.
Adaptogens and Digestive Enzymes in Foundational Supplements
In addition to vitamins and minerals, some foundational supplements include adaptogens and digestive enzymes. Adaptogens are natural substances, often herbs, that help the body adapt to stress and promote balance in hormone levels. Popular adaptogens include ashwagandha and Rhodiola rosea, which are commonly used to reduce stress and support energy levels.
Digestive enzymes, on the other hand, aid in breaking down food and absorbing nutrients. For individuals who experience digestive issues, such as bloating or difficulty breaking down proteins or fats, digestive enzyme supplements can offer significant relief and improve nutrient absorption.
Foundational supplements that include adaptogens and digestive enzymes can provide a broader spectrum of health benefits, offering not just nutritional support but also improved stress resilience and digestive function.
Probiotics and Prebiotics
Another key area of health that is increasingly gaining attention is the gut microbiome. The gut microbiome consists of trillions of bacteria and other microorganisms that play a vital role in digestion, immune function, and even mental health. An imbalance in gut bacteria can contribute to various health issues, including digestive problems, inflammation, and mood disorders.
To support gut health, many people turn to probiotic and prebiotic supplements. Probiotics are live bacteria that can help restore a healthy balance of gut flora, while prebiotics are fibres that feed the beneficial bacteria in the gut.
Foods such as yoghurt, sauerkraut, and kimchi are rich in probiotics, while fibre-rich foods like oats, bananas, and legumes provide prebiotics. However, for those who struggle to get enough of these foods in their diet, probiotic and prebiotic supplements can be a convenient and effective way to promote gut health.
It’s worth noting that the best probiotics are usually those that require refrigeration to maintain their potency. When choosing a probiotic supplement, look for high-quality options with diverse strains of bacteria, as diversity in the gut microbiome is associated with better overall health.
Targeted Supplements
While foundational supplements aim to fill gaps in general nutrition, targeted supplements are designed to address specific health goals, such as improving sleep, enhancing focus, or supporting hormone balance. Below, we will discuss some of the most popular targeted supplements and how they can help optimise health.
Supplements for Sleep
Sleep is a cornerstone of good health, affecting everything from mood and cognitive function to physical performance and immune system strength. Many people struggle with getting enough high-quality sleep, leading them to explore supplementation options.
One popular sleep aid is magnesium, particularly forms like magnesium threonate and magnesium bisglycinate, which are known to support relaxation and improve sleep quality. These forms of magnesium are easily absorbed by the body and can help individuals who have trouble falling asleep or staying asleep throughout the night.
Apigenin, a compound found in chamomile, is another supplement commonly used to aid sleep. Apigenin helps to calm the nervous system, making it easier to wind down and reduce racing thoughts before bed.
Supplements for Focus and Cognitive Enhancement
For those seeking to enhance focus and mental clarity, a variety of supplements can help support cognitive function. L-theanine, an amino acid found in tea, is known for promoting relaxation without drowsiness, making it a popular choice for improving focus without the jitteriness associated with stimulants like caffeine.
Alpha-GPC and citicoline are two other supplements that are often used to boost cognitive function by increasing levels of the neurotransmitter acetylcholine, which is essential for memory and learning. These supplements are frequently used by individuals looking to improve focus, memory retention, and mental stamina.
Hormone Support Supplements
Hormones play a critical role in regulating mood, energy levels, and physical performance. For those seeking to optimise hormone levels, certain supplements can be highly effective.
Ashwagandha, mentioned earlier as an adaptogen, is also widely used to support healthy testosterone levels and improve stress resilience. For individuals experiencing hormonal imbalances due to stress or ageing, ashwagandha can be a natural way to support better hormonal health.
DHEA (dehydroepiandrosterone) is another supplement that is commonly used to support hormone balance, particularly in individuals over the age of 40, as DHEA levels naturally decline with age. However, it’s important to consult a healthcare provider before taking DHEA, as it can affect various hormone systems.
Establishing a Supplement Routine
When developing a supplement routine, it’s essential to approach the process with careful consideration. Supplements should not be taken haphazardly, and it’s important to ensure they fit into a broader framework of healthy living.
Here are a few key points to keep in mind when incorporating supplements into your health routine:
- Identify Your Needs: Start by assessing your current health status, lifestyle, and goals. Are you getting enough sleep? Are you regularly eating nutrient-dense foods? Are there specific areas (e.g., energy, focus, sleep) where you feel improvement is needed?
- Prioritise Foundational Health: Before reaching for targeted supplements, make sure your foundational health is in order. This includes getting enough sleep, eating a balanced diet, and managing stress. Supplements should be viewed as an enhancement to an already healthy lifestyle
