The Hottest Supplements of 2019 So Far

hottest supplements 2018

In a major 2017 consumer survey, 76% of Americans said they use supplements. Even more importantly, 3 in 4 said they see the supplement industry as trustworthy. This consumer confidence is compelling more Americans than ever to explore the world of vitamins, protein powders and other dietary supplements. But which ones are they flocking to?

If you follow the industry as closely as we do, you already know that each year brings new trending supplements. In 2017, the ews/2017-10-20/crn-survey-finds-increase-in-dietary-supplement-usage” target=”_blank” rel=”noopener”>most widely-used supplements were the multivitamin, Vitamin D, and Vitamin C, with calcium, Vitamin B Complex and protein rounding out the Top 6.

Last year was dominated by Vitamin D and turmeric. This year, a new set of supplements are grabbing headlines. Here’s a quick list of the most popular supplements of 2019 thus far.


Riding its wave of popularity into 2019, this gut-boosting bacteria is still driving palpable interest in both the fitness and wellness crowds. Probiotics was a $35 million market in 2015, and that doesn’t even account for its rising popularity over the last few years.

Why are so many Americans going crazy for probiotics? It’s about more than just digestive health. A study by the International Journal of Food Sciences and Nutrition showed that probiotics can reduce your overall body weight—modestly, but still enough to boost your overall wellness efforts and reduce the risk of diseases like Type 2 Diabetes.  The bacteria boost that probiotics deliver can also be shown to help your skin and improve your immune health.

Pre-Workout Supplements

It can be a hassle take 10 supplements before a workout. But at the same time, we know that supplements can enhance your performance—supplements 2018especially during strength training. Enter Multi-Ingredient Pre-Workout Supplements (MIPS), a rising star in the supplement world.

What’s all the buzz about? For starters, there’s solid research to show that MIPS can enhance your ability to complete more reps and have more power during sprinting. Its effects aren’t as clear on aerobics, but if you’re after a better strength session and more energy during HIIT, then this supplement is worth exploring.

MIPS typically include molecules and minerals that promote muscle building and energy: N-Acetyl L-Cysteine, beetroot extract, BCAAs, Alpha-GPC, caffeine and creatine, to name a few.


While creatine’s popularity might not be new, it’s definitely enduring. This muscle-building supplement has long been a choice of athletes, and for good reason: it helps produce extra energy that fuels your muscle tissues to work harder, for a longer period of time. Creatine doesn’t work for everyone, but if your body reacts well to this supplement, it has been shown to boost your resistance training performance.


Like Vitamin D, calcium supplements have been touted for their ability to strengthen bones. But calcium supplements aren’t just for the aging population; they’re also being used by fitness enthusiasts looking for protection against exercise-related bone loss. But do calcium supplements deliver on this promise?

The answer is yes and no. A preliminary study did show that athletes who lose tremendous amounts of calcium during exercise could replenish some of this supply through calcium supplements—if they take them at the right time. Men who took calcium supplements before their endurance exercise lost less calcium than those who took the supplements after their training.

But other research points to the risks (and potential ineffectiveness) of calcium supplements. One study showed that men who took more than 1,000 mg of calcium daily had an increased risk of heart disease. And keep in mind that you can also get calcium naturally from kale, salmon and other foods.


The latest powder to spark a craze is undeniably collagen. Long been used for its beauty effects, this structural protein is now flying off the shelves as a solution for soothing achy joints, boosting digestive health and even improving your workout performance. But is the hype backed by science?

Collagen makes up 30% of the structural proteins in the human body, and we naturally produce it through the food we eat. But our production of collagen decreases with age; hence, the search for a supplement to replenish our bodies of this crucial protein. The collagen supplements on the market today suggest that they can improve bone health and aid in the repair of muscles post-workout. But experts say that there’s no definitive proof that collagen we eat turns into collagen in our tissues, meaning the jury is still out about this trending supplement.

The first few weeks of 2019, we’re already seeing supplements like collagen, MIPS and calcium dominating our news feed, consumer reports and, most importantly, research studies. With any supplement, trending or not, it’s crucial to have a trusted source that helps you separate hype from results. Check back with us at for more supplement reviews and news that you can trust.

Protein Powder

Last, but definitely not least, is protein powder. Protein powder used to just be something athletes and bodybuilders used, but now its something literally EVERYONE is using. Everyone and their mother has protein powder in their kitchen nowadays…from people who are trying to increase their protein intake to gym-goers looking to build some muscle, to professional bodybuilders, and everyone in between.

Protein powder is definitely a must-have if you’re looking to lose some weight or gain some muscle. However, it’s extremely important to use a super high-quality source of protein such as whey protein hydrolysate.

Low-quality sources of protein can cause fat gain, gastrointestinal distress, and many other digestive issues. Some studies even suggest that low-quality forms of protein aren’t even efficiently digested and absorbed by the body, which ultimately makes them useless.
