Over the last five years I’ve developed a strong interest in nutritional neuroscience and how specific foods and supplements influence the body and brain. One concept that really changed how I evaluate supplements is bioavailability. Before I understood this, I mostly chose supplements based on brand popularity or marketing. But brand recognition alone doesn’t guarantee that your body can effectively absorb and use what’s inside the capsule or powder. I also learned that some products include fillers, binders, or low grade forms of nutrients that may reduce how efficiently the active ingredient is absorbed. That doesn’t automatically make them “bad,” but it can affect overall value. Bioavailability refers to how much of a nutrient is actually absorbed into the bloodstream and becomes available for the body to use. It’s influenced by several factors: • The chemical form of the nutrient • Dosage • Delivery method • What you take it with (for example, fat soluble vitamins with dietary fat) • Your digestion and metabolism Understanding this shifted my approach. Instead of just asking “Is this brand popular?”, I started asking: • What form of the nutrient is used? • Is the dose evidence based? • Is there transparency in testing and labeling? • Does this form have good absorption data behind it? It doesn’t mean the most expensive supplement is always better or that cheaper ones are useless, but it does mean quality, formulation, and context matter. Have you ever looked into whether the supplements you’re taking are in forms your body can actually absorb and use effectively?

A few years back I started looking for ways to reduce how dependent I felt on Ritalin. That led me down the rabbit hole of experimenting with different compounds to support focus and mental clarity. The one that genuinely stood out for me was L-tyrosine. It wasn’t a magic switch, but I noticed a clearer sense of control and concentration that felt more stable and longer lasting. Here’s the science in simple terms: L-tyrosine is an amino acid the body uses to produce key neurotransmitters, including dopamine and noradrenaline. These chemicals play a major role in motivation, attention, and executive function. Tyrosine is converted into L-DOPA and then into dopamine, which the brain relies on to regulate focus and drive. ADHD is closely linked to dopamine imbalance in the prefrontal cortex, which controls attention, planning, and impulse control. Unlike stimulants that force dopamine release, L-tyrosine supports the brain by providing the building blocks needed to produce dopamine and noradrenaline naturally. Over time, this can help stabilize focus, support sustained attention, reduce mental fatigue from task switching, and create a stronger sense of control rather than relying on stimulation. For many, this results in focus that feels more natural and consistent, with fewer crashes and more predictable mental energy throughout the day. Question for the group: What have you found that genuinely helps you manage focus over the long term? Supplements, routines, training, or mindset shifts. What has actually made a difference for you?

Lately I have been paying more attention to how staying hydrated affects the way I think and feel. It is surprising how something so simple can throw you off without you realising it. For a long time I misunderstood my body’s messaging. Whenever I felt a drop in energy or a sense of mental heaviness, I assumed it meant I needed coffee. What I thought was a caffeine craving was actually my body telling me I was thirsty. I never stopped to consider how much coffee can dehydrate the body. Coffee has its place, but using it instead of water was doing me a real disservice. Looking back, a lot of the fogginess, irritability, and lack of focus I felt on certain days had nothing to do with stress or sleep. Most of the time my body simply needed water. The signs were subtle, but they were there long before I felt thirsty. Once I became more intentional with hydration, especially on busy days or training days, I noticed a real shift. 🔥My mood improved. 🔥My focus sharpened. 🔥My energy felt more stable. Nothing dramatic, just the difference between feeling out of rhythm and feeling aligned. Today’s focus 🗓️ Drink a little more water than you usually do. Notice how your mind responds.

Today my whole day was turned upside down. My daughter had to stay home with a tummy bug, and as a creature of habit, it threw off the entire rhythm of my workday. At first, I felt the frustration of losing my routine. But it didn’t take long to realise my focus was pointed in the wrong direction. My daughter is almost never sick. If there was ever a day to shift gears and show up for her, it was today. It reminded me of something simple: Our attention shapes our experience. And sometimes the most important thing we can do is redirect it toward what truly matters. ⭐️Attention is our real currency⭐️ We lose it to small distractions every day, but we also lose it when we cling too tightly to our plans. Sometimes the real performance skill is adapting without resisting. ❓When your day gets thrown off, how do you reset your focus?

I’ve realised something simple but powerful. When my sleep is good, everything else gets easier. My patience is better, my thinking is clearer, my training feels lighter, and even small stresses feel manageable. Sleep is the foundation of recovery. It is where the body repairs, hormones reset, inflammation drops, and the brain clears waste so you can show up with a sharper mind the next day. And when sleep is off, I feel it everywhere. I wake up already behind. My mood is shorter. My focus fades faster. Even my discipline takes a hit. ⭐️How many hours of sleep do you need to optimize your day?⭐️
