Mastering Protein Intake
Depending on your age, gender and activity level, your protein intake is going to look vastly different to the next person, and for someone who’s never really given protein a second thought it can be scary to even attempt to eat your required amount. Let’s take a second to break that number down, and make it as easy as possible for you to actually get it down. Know Your Number You can find online calculators everywhere that can help you find your daily caloric amount for cutting or bulking, what micronutrients you need and yes even your recommended protein amount. To use the Australian Government's advice, we can find approximate levels below: Females 19yo - 30yo: RDI 46 g p/day (0.60 g/kg) Males 19yo - 30yo: RDI 64 g p/day (0.84 g/kg) These figures are just approximations of RDI’s, this doesn’t take into account fitness levels, dietary requirements or the like. To be easy, we can make the example following the RDI’s above, that a female that’s 60kg at a moderate activity level needs about 50g-60g of protein per day, considering that with higher caloric demands in physical activity will require more protein. How To Get It In For someone with the goal of eating 100g-150g+ of protein per day, it can seem like a struggle to actually get it all in, but following some recommendations below, it can be a lot easier than you might think. Have Protein With Everything You Eat. Snack? Meal? Make sure whatever it is, has at least 20g of protein included. It doesn’t have to come from the actual food, but having a protein shake next to you can be a pretty easy way to get the habit going. Meal Prep. If you know exactly what you meals are going to look like day to day, it becomes a lot easier to find inclusions of protein everywhere. If know how many calories you have left the day for example, you can make the choice between a shake of some sort, or a full protein based meal. Wrapping Up Like with most things that are activity or nutrition based, simply but consistent, beats flashy diets every time. If protein becomes a non-negotiable in every meal, or apart of you routine, you can aim for higher and higher amounts.

What Are Greens Powders?
When exploring a supplement shop, you’ll tend to see a few things on the shelves. You’ll see products claiming health and wellness, performance enhancing, recovery focused, lots of buzzwords. With a product like a greens powder however, is all of the marketing obsolete when you can take an all-encompassing “health” powder? What Are Greens Powders Made Of? A greens powder typically is made of a blend of nutrient-dense plant-based ingredients like leafy greens, algae, grasses, and vegetables. It may also include herbs, fruits, probiotics, and enzymes to support digestion and overall health. The powders are often rich in vitamins, minerals, antioxidants, and fiber, offering a convenient way to boost daily nutrient intake, supporting those especially deficient in daily vegetable consumption. These powders are designed to support overall health by providing a concentrated dose of these essential nutrients from those various sources. They may help boost energy levels, improve digestion, and enhance immune function due to their high content of vitamins, minerals, and antioxidants. Additionally, greens powders may aid in balancing the body's pH levels, reducing inflammation, and supporting gut health, contributing to improved skin, mood, and overall vitality. Are There Side Effects? While greens powders are generally safe for most people, there can be some side effects, particularly if taken in large amounts or if you have sensitivities to certain ingredients. Side effects can include: Allergic Reactions: If you're allergic to certain plants, herbs, or algae in the powder, you may experience reactions like itching, swelling, or difficulty breathing. Interaction With Medications: Certain greens powders may interact with medications, particularly blood thinners due to high concentrations of Vitamin K, or immunosuppressants due to the high antioxidant content. The Bottom Line Overall, it’s safe to say greens powders aren’t an essential supplement by any means, but fit the description of one perfectly. You can get the nutrients fully from whole foods in your day to day diet, however, greens are a great way to get all the essentials into your day, extremely conveniently.

Navigating Creatine
As widely available and widely studied creatine supplements are in the fitness industry, there are always ways to make choosing a creatine supplement confusing and overwhelming. The benefits are easy to understand, so why shouldn't knowing what you’re looking for be easy too? Let’s go into the different variations of creatine and find what’s best for you. A Background On Creatine Creatine is one of the most researched supplements in the world, known for its role in improving strength, power, and muscle performance. It works by helping your muscles produce more energy during high-intensity exercise. Beyond performance, studies also show creatine supports muscle growth, recovery, brain health, and even endurance. Its safety and effectiveness are backed by decades of scientific research, making it a reliable choice for both beginners and advanced lifters. Creatine is proven to be a supplement with a multitude of benefits, and very low risk of side effects. Over the decades, many new types of creatine have been marketed as either more effective than the original, or a boosted version of it. Creatine Nitrate claims to be more soluble than the original, with its bond of nitrate being easier to digest. The same can be said about Buffered Creatine or Ethyl Ester, where taking it is an "improved" version of the original source, with various benefits mainly seen on a microscopic level. Two types however, stand out among the crowd as the most popular, and most effective. Creatine Monohydrate Creatine Monohydrate is the most researched and trusted form of creatine, known for its effectiveness, safety, and affordability. It has all the various benefits of creatine, while also supporting muscle growth and recovery. With decades of studies proving its benefits, and a price point much lower than newer alternatives, creatine monohydrate stands out as the best-value option for athletes, lifters, and anyone looking to improve performance. Creatine Hydrochloride Creatine HCL (Hydrochloride) is a newer form of creatine that’s praised for its superior solubility and easier digestion compared to monohydrate. Because it mixes well in water and is often taken in smaller doses, it’s a popular choice for those who experience bloating or stomach discomfort with other forms. While research on HCL is more limited, many people find it convenient and effective, though it generally comes at a higher price than creatine monohydrate. Wrapping Up The bottom line is all creatine generally is going to have a benefit on you, your performance and recovery. Taking monohydrate gives you the benefit of knowing what you’re taking is researched thoroughly, taking HCL gives you that same benefit, with the inclusion of people who may have issues digesting monohydrate. Always consult a nutritional specialist to see what the best version is right for you.
