It’s True: Whey Protein Improves Vascular Function (With Drew Price)

26th July 2022

By Beth Shelper

Here at Innermost, our research and science-backed, nutrition-loving values mean that we get to work with some of the best brains in the nutrition game. Innermost ambassador Drew Price is a prime example of this, and if you’ve been around here for a while, you’ll definitely be familiar with Drew and his work.

Drew’s latest research into cardiovascular endurance, and the link between the cardiovascular system, vascular function and whey protein – which he co-authored with the head of The Nutrition Society and a host of other senior nutrition academics, demonstrates a clear relationship between whey protein consumption (such as The Strong Protein) and improved vascular function.

Great news! But how?

First, to get to the bottom of that, let’s first define what the cardiovascular system is, discuss cardiovascular endurance, and then we’ll get to the study. Sound good?

What is the vascular system and vascular function?

The vascular system (sometimes referred to as the circulatory system), refers to the vessels (ie the arteries, veins, capillaries and the heart), that carry blood throughout the body.

As you’re probably aware, the vascular system is vital to our health and survival, and is the primary carrier of not only blood, but as a result, the oxygen and nutrients that we need throughout the body.

What is vascular function?

With that in mind, vascular function is a key marker in cardiovascular health and with that, cardiovascular endurance - which measures just how well you can exercise, to what intensity, and for how long (amongst other important areas of health, of course).

Vascular function refers to the body’s ability to maintain normality, or ‘homeostasis’ in referral to the duties of the vascular system, that is – in pumping blood around the body. Make sense?

Now, due to the obvious importance of this function, scientists, researchers and nutritionists often research nutritional, behavioural and even psychological factors or values that have an impact on the vascular function, to determine how (and if) this can be improved, with risk factors reduced.

Now, that leads us on pretty nicely to Drew’s study into vascular function…

The effects of whey protein on vascular function

With the aim of investigating the nutritional and health impact of whey protein and vascular function and the reduction of cardiovascular disease, Drew and the team set out to review the evidence provided by a collection of studies and randomised trials. The investigations noted the impact of whey proteins and their peptides (aka, the strings of amino acids), which, as we know are the building blocks of protein. This was done to identify their relationship between vascular function and also any related health issues such as blood pressure, too.

The results: the link between why protein and vascular function

Analysing whey proteins and their impact on our nutrition and health is of particular interest due to their complexity, along with other dairy sources and foods. These high-quality proteins are one of the most popular included in protein supplementations (as well as examples such as casein), and is commonly associated with muscle gain, weight training and similar.

The investigation analysed studies into whey protein and their impact on vascular function, with many of the studies analysed showing both short and long term benefits in terms of vascular function and overall health, too. Of the eighteen studies analysed, significant results were noted, with those including an reduced body fat and a reduction in hypertension, with these results becoming more notable with an increase in exercise, too.

Summary

There we have it. The investigation, conducted by our very own Innermost ambassador Drew Price and his team: Kim Jackson, Julie Lovegrove and David Givens show that not only can whey protein supplementations such as The Strong Protein be beneficial in reaching your fitness goals and maximising your performance, but in lowering your risk of cardiovascular diseases and maintaining a healthy vascular function, too.

Good work, Drew!

The Truth About Electrolytes
Electrolytes. You’ve seen the word plastered across sports drinks, hydration tablets, and wellness blogs. You know they have something to do with hydration and performance. But do you really need them? Or is this just another overhyped wellness trend? The Hard Truth About Hydration Most people think hydration is as simple as drinking enough water. Wrong. If you’ve ever felt exhausted despite drinking litres of water, struggled with brain fog, or suffered from muscle cramps and sluggish recovery after exercise, there’s a good chance you’re missing a key piece of the puzzle: electrolytes. Electrolytes are essential minerals like sodium, potassium, and magnesium that keep your body running smoothly. They: Regulate hydration – Helping your body absorb and retain water effectively. Boost performance – Ensuring muscles contract properly, nerves fire efficiently, and your body keeps up with demands. Reduce muscle cramps – Preventing painful spasms and fatigue caused by mineral depletion. Improve brain function – Supporting cognitive performance, reaction times, and mental clarity. Maintain pH balance – Keeping your body’s internal systems stable for overall well-being. But here’s the problem: when you don’t replenish electrolytes, your body feels it. Dehydration, fatigue, dizziness, and even impaired cognitive function can all stem from electrolyte imbalances. If you’re training hard, sweating, fasting, or simply not eating enough electrolyte-rich foods, you’re losing more minerals than you think. The Science of Electrolytes & Hydration Even mild dehydration affects brain function. Studies show that a 2% drop in hydration can impair memory, focus, and reaction time (Journal of the American College of Nutrition, 2019). Electrolytes prevent muscle cramps. Sodium, potassium, and magnesium imbalances are the biggest culprits behind muscle cramps and post-workout fatigue (Sports Medicine, 2021). Performance drops by up to 20% when you’re dehydrated. A 2020 study found that a 1-2% decrease in hydration levels can lead to a 10-20% decline in endurance and power output (European Journal of Applied Physiology, 2020). Water Alone Won’t Cut It A lot of people assume that staying hydrated is just about drinking more water. But here’s the problem—drinking too much water without electrolytes can actually make things worse. Overhydration (yes, that’s a thing) can dilute sodium levels in your blood, leading to hyponatremia. Symptoms range from headaches and dizziness to nausea, confusion, and in extreme cases, even life-threatening complications. That’s why professional athletes, marathon runners, and high performers don’t just drink plain water—they strategically replenish electrolytes to keep hydration levels balanced. How to Stay Properly Hydrated Want to make sure you’re actually hydrating your body the right way? Here’s how: Drink smarter, not just more. Hydration isn’t just about intake—it’s about absorption. Your body needs minerals to properly retain water. Eat water-rich foods. Cucumbers, watermelon, oranges, and leafy greens naturally contain electrolytes and help with hydration. Replenish electrolytes, especially after sweating. Whether you're working out, fasting, or in hot weather, your body needs sodium, potassium, and magnesium to maintain hydration and muscle function. Ditch sugary sports drinks. Many electrolyte drinks are loaded with sugar, artificial flavours, and unnecessary additives. Your body needs the right balance of minerals—not a sugar spike. Electrolytes & Everyday Life Think electrolytes are only for elite athletes? Think again. They play a vital role in daily life, too. Morning sluggishness? Your body loses electrolytes overnight. A small dose first thing in the morning boosts energy and mental clarity. Post-workout fatigue? Sweat = lost minerals. Replenishing prevents muscle cramps and aids recovery. Fasting or low-carb diets? When you reduce carbs, your body flushes more sodium and potassium—leading to fatigue and dizziness if you don’t replenish. After drinking alcohol? Alcohol is a diuretic, meaning it causes fluid and mineral loss, which is why you wake up dehydrated and groggy after a night out. Proper electrolyte replenishment before bed can help reduce hangovers. The Problem With Most Electrolyte Drinks The issue with many “electrolyte” products on the market? They don’t contain every electrolyte your bodies need or they contain electrolytes in super low concentrations so it’s more of a marketing gimmick than anything else. In addition, many are loaded with sugar and artificial ingredients including silica; an ingredient I despise and will be talking more about on our social channels. Most mainstream electrolyte drinks contain: Excess sugar – Leading to unnecessary calorie intake and blood sugar crashes. Artificial additives – Unnecessary chemicals that do more harm than good. Cheap mineral sources – Making them less effective at restoring balance. Your body deserves better. The Innermost Solution The Hydrate Blend – a science-backed, 100% natural electrolyte formula that’s free from silica, artificial ingredients, and sugar. It hydrates up to 5x more than water alone, making it perfect for everyday hydration and workouts. Unlike most sports drinks, it delivers every single electrolyte in the right balance without sugar or synthetic fillers.

Final Thoughts Hydration isn’t just about drinking more water—it’s about absorbing it effectively. If you’re constantly feeling tired, sluggish, or cramping up, chances are your electrolyte balance is off. So next time you feel off, don’t just chug another glass of water—make sure you’re replenishing the right minerals, too. Read more
