| Lifting the lid on pre-workout supplements |
| If you're interested in fitness, you've likely come across pre-workout supplements (and we don't just mean that ultimate workout snack — the banana). These products contain a wide range of ingredients and are touted to enhance energy and boost athletic performance. But are those claims backed by science? |
| Key active ingredients: |
| | • | Nitric oxide precursors: Compounds like L-arginine and L-citrulline are believed to improve blood flow, which may, in turn, contribute to better athletic performance. | |
| | • | Caffeine: Known to boost mental alertness, caffeine is a common ingredient in these supplements that can improve exercise performance. | |
| | • | Creatine: Your body naturally produces creatine, but creatine supplementation may help enhance muscle mass, strength, and exercise performance. Creatine can also interact with caffeine to add an extra boost, though not without potential costs. | |
| | • | Beta-alanine: Included in many formulas, this amino acid helps reduce acid buildup in your muscles, potentially allowing for longer and more intense workouts. | |
| While some ingredients may have benefits, it's important to be cautious. Artificial sweeteners found in these supplements can sometimes cause gastrointestinal issues. |
| Additionally, consuming excessive amounts of caffeine can lead to elevated blood pressure and other side effects. |
| Regulation of pre-workout supplements is not very strict, so look for products that are tested by third-party organizations for quality assurance. |
| Good nutrition, hydration, and sleep are likely to play more significant roles in your performance. It's also advisable to consult a healthcare professional before trying new supplements, especially if you have existing health conditions. |

| Branched-chain amino acids (BCAAs) |
| BCAAs are gaining attention in the fitness world, so it's no wonder so many gym vending machines are full of products that contain them. But what are they? |
| Three essential amino acids — leucine, isoleucine, and valine — happen to have a unique branched structure and play a crucial role in protein synthesis. |
| Here's what they can do for you, in and out of the gym. |
| 🏋️♀️ Boosting your BCAA intake might help build muscle and increase endurance: |
| | • | BCAAs are primarily broken down in your muscles, fueling energy production during exercise. | |
| | • | Leucine is a superstar in muscle protein synthesis. | |
| | • | Isoleucine and valine are key players in energy production and blood sugar regulation. | |
| 🏃 Consuming BCAAs before or after your workout could cut down on recovery time: |
| | • | BCAAs may lessen fatigue by reducing serotonin production in your brain. | |
| | • | They may also reduce soreness by lowering levels of enzymes linked to muscle damage. | |
| | • | However, these effects can vary among individuals. | |
| 💼 BCAAs for health as well as fitness: |
|
| | • | An average daily intake of 15 grams could potentially reduce the risk of obesity. | |
|
| 🍽️ How to get 'em: |
| | • | BCAAs are plentiful in a variety of protein-rich foods, such as meat, fish, dairy, tofu, and quinoa. | |
| | • | If supplementing, consult a healthcare professional to find out the right dosage for you, especially if you're taking BCAAs for liver health. | |
| 👍 Safety & side effects: For most people, BCAA supplementation is safe. However, people with a condition called maple syrup urine disease should limit their BCAA intake. (Just don't be dry scooping.) |
| 🔑 The bottom line: BCAAs could be a secret weapon for muscle growth, workout performance, and maybe even health benefits beyond the gym. However, supplementation isn't always necessary — a diet rich in protein-packed foods might be all you need. |
