How To Spot A Bad Supplement

“I don’t trust supplements; they aren’t regulated. I’m going to just get what I need from food.” 

I’ve heard these statements from countless people who are first embarking on a health and fitness journey. Based on the general reputation of the supplement industry, I can appreciate the initial sentiment. Although, the ideas of optimal nutrient sufficiency from our current diet and the perceived lack of regulation are both myths.1-4 Our diet is not as nutrient dense as it once was (most of us do not consume nearly as much produce as we should), and the FDA (and the FTC, for that matter) does in fact have a role in regulating the industry and its claims. 

However, the dirty laundry of the nutritional supplement industry seems never-ending. As recently as 2015, the lid was blown off of several recognizable brands and companies when it was discovered that key ingredients on the labels were missing in the products. Earlier this year, a consumer advocacy group, the Clean Label Project, exposed contaminants in several common brands. Earlier this week, headlines were swirling due to a just-released study exposing hidden and potentially dangerous ingredients (ie: pharmaceutical drugs) found in some weight loss, sexual performance enhancing, and muscle building supplements that were not listed on the label. It’s sad and scary, but not surprising, as these specific categories of supplements have been in the negative limelight for quite some time.5-7

All in all, it’s easy to understand why there is a healthy amount of skepticism. 

What’s most frustrating, however, is that the bad apple companies with shady ingredients and manufacturing shortcuts at the expense of their customers’ health end up tainting the broader perception of the industry, despite the fact that there arecompanies, like Life Time, who prioritize the customer’s health and safety above all else. The widespread confusion and distrust is why Life Time decided over two decades ago that there must be full control over formulation, ingredient selection, production, and final testing on what is offered to our members. Through carefully selected partners and rigorous quality control standards, the supplements we offer are the same ones we use for ourselves and for our families. 

As a result, our clients consistently report back amazing improvements to their health, body composition, vitality, gut function, lab work, and performance when the right, quality supplements are combined with healthy nutrition and exercise strategies. 

While it can feel overwhelming, here are a few checkpoints to use as a first-pass screening to weed out the bad guys when it comes to what you’re including in your daily routine. If you see any of the following: run. It’s a sign that the manufacturer is prioritizing their profits over your health. 

1. Cyanocobalamin: A cheap form of Vitamin B12. 

You might need to dig through both the nutrient facts label and the ingredients when looking for this name. As suggested, this form of Vitamin B12 is cost-effective for the manufacturer, but is not the active, natural form of the nutrient. In order to use the cobalamin group from the cyanocobalamin form, our liver must first remove (and eliminate) the cyanide molecule and replace it with a methyl group – an extra step that comes with some unnecessary toxic potential. Tied to heart health, mood, and energy levels, ensure that your supplementation contains the methylcobalamin form of Vitamin B12. While it’s more expensive, it’s worth it when it’s more effective and adds less of a burden on your liver. 

2. Folic Acid: Surprise, it’s synthetic. 

Most people might think of folic acid as the non-negotiable nutrient needed during pregnancy to prevent neural tube defects. Our food fortification laws require dozens of foods to have this synthetic form of folate added, but that doesn’t make it “healthy” or mean it’s beneficial for everyone. Many are surprised to learn that folic acidis synthetic and different from natural folate we require for normal physiologic development and function. Whether or not you’re pregnant, folate is needed for cardiovascular health, DNA synthesis, and prevention of certain types of anemias. Similar to the Vitamin B12 situation mentioned above, it’s key to look through the ingredients and the facts label to check the form of folate found in your supplements. Instead of folic acid, choose supplements that have a methylated folate form, often listed as 5-methyl-tetrahydrofolic acid glucosamine salt or 5-methyltetrahydrofolate. This form is readily used by our cells (does not need to be converted to be put to use) and is less likely to mask a Vitamin B12 deficiency, build up to higher-than-optimal levels in the bloodstream, or interfere with medications.And of course, if you’re pregnant or planning on becoming pregnant, be sure to work with your doctor to ensure you’re taking in the right forms and amounts of folate. 

3. Zinc oxide, cupric oxide, manganese sulfate.

For the best absorption and utilization, minerals often have to be wrapped in amino acids (protein building blocks). When they have this type of wrapping, they’re referred to as “chelated” (pronounced key-lated). 

Lower quality supplements will often have “oxide” forms of zinc and copper, as well as the sulfate form of manganese.9Chelated versions will typically have “chelate” or “bisglycinate” listed in the ingredients and on the label. When supplements contain bisglycinate, take note: it takes up a lot of physical space, so you’re likely going to be taking several capsules. 

4. Artificial Sweeteners (Sucralose, Acesulfame-Potassium), Artificial Flavors, Carrageenan, FD&C Colors and Dyes.

When it comes to colors, flavors, and sweeteners, aim to go all-natural whenever possible. From the supplement line all the way to the food offered in the Life Café, this is a theme and non-negotiable at Life Time, and for good reason. In fact, the FDA recently announced it will “de-list” seven artificial flavoring compounds currently allowed as food additives amid emerging evidence the compounds may cause cancer in animals.

Some evidence points to possible negative impacts of artificial sweeteners on gut health.10 Other research suggests that with our four-fold increase consumption in the last 50 years, artificial flavors could be a contributor to ADHD and behavioral issues, and artificial colors and dyes may even have some carcinogenic activity.11-14 Carrageenan, sometimes used in lower-quality products to enhance the texture of powders and liquids, has been tied to rheumatological and intestinal inflammation and inflammatory bowel disease.15, 16

When using powder-based supplements, higher quality options tend to use natural flavors and colors and are usually sweetened with stevia (sometimes with a gram or two of sugar to offset any bitterness) or monk fruit instead of the unmentionables.  

5. Tablets and gummies. 

The delivery method of a given supplement has significant impact in whether or not the ingredients get used by your body or just end up as expensive waste. Tablets are often compressed and glued together with binders, making them difficult to break down in the GI tract. Gummies, while a genius marketing strategy, have limited space and cannot physically contain therapeutic amounts of certain vitamins and minerals, and they almost always contain a lot of added sugar or artificial sweeteners or colors. 

Powders, gels and capsules (which are filled with powders) tend to be easier to breakdown, liberating the contents so they can be better absorbed. While they’re not as fun as the weakly vitamin-laced, ineffective candy gummies, they are a much better use of your money and efforts.  

6. Outlandish, all-encompassing claims.

Listen: When it comes to supplementation, there is no cure-all. For any company that is having you skip over the basics to instead obsess over a miracle tincture of exotic, remote-island berries, herbs and mushrooms to be taken three times a day, your “nonsense meter” should go off. 

It’s so crucial to first focus on supporting your body’s functioning with what it alreadyshould have and recognize easily: micronutrients (vitamins & minerals), omega-3 fatty acids, fiber and beneficial bacteria to start. If that’s a given, focus on healthy options that make your life easier, such as a quality protein powder made into a quick shake with organic berries and almond butter when you’re running out the door instead of hitting up the drive through for a processed and inflammatory processed food breakfast. Lastly, implement targeted nutrients or botanicals based on your individual goals, symptoms, lab work, and health status with the help of a qualified medical practitioner.

Is Collagen Really Worth All the Hype?


You’ve probably gotten wind of the collagen hype, but before you write it off as just another fad, our expert coaches break down what it is, the benefits, where it can go wrong, and how you can add the right type of quality collagen into your eating plan. 

What Is Collagen?

Collagen, the uncooked form of gelatin, is the major structural protein that forms the connective tissue and extracellular matrix of the human body. Collagen is the durable, supportive material that gives our bones, organs, skin and connective tissue shape, flexibility and strength. About 90% of our organic bone mass and about 80% of our skin is made of collagen. [i]

Structurally, collagen is a tough, fibrous form of protein that isn’t well digested by humans unless it’s cooked or simmered for many hours to “release” it’s repeating amino acid peptides of glycine-proline-x (where “x” can be any amino acid). In order to get enough collagen, we must consume an adequate amount of bony fish, fatty fish, the skin of chicken or cuts of meat that have the connective tissue slow-simmered into the broth. 

Why Does It Matter? 

We all need enough protein to sustain the integrity of our tissues, skin and digestive system. If you aren’t getting enough collagen in your dietary plan, you could be missing out on a variety of benefits. 

Younger, suppler skin.

Have you been disappointed by the latest “age-defying” topical serums and lotions, or frightened by the cost of other cosmetic procedures that promise more youthful skin? Then you’ll be pleased to know this: several studies have shown that oral supplementation with collagen peptides significantly improves skin hydration and elasticity, and significantly reduces wrinkle depth in as little as a few weeks. [ii] [iii] [iv]

Using collagen peptides as a supplement has also been shown to have a beneficial effect on cellulite morphology, essentially helping to smooth out the uneven protein matrix that supports our skin. [v] 

Leaner and more muscular body.

The benefits of protein supplementation in active individuals are well-researched and well-known. And now we find that collagen peptides may offer unique benefits to elderly men with age-related muscle loss (sarcopenia). One double-blind study showed that daily collagen peptide supplementation, in combination with resistance training, improved body composition and increased muscle strength in elderly sarcopenic men when compared to the placebo. [vi] The men taking collagen peptides after their workouts gained more lean mass and lost more fat mass than those who didn’t receive additional collagen peptides postworkout.

More durable joints.

Whether you have stiff joints, tight tendons or frequent and intense training sessions that put stress on the joints, you may benefit from a daily dose of collagen peptides. Over the span of a few months, collagen peptide supplementation appears to promote structural integrity and mechanical properties of tendons. [vii] Collagen peptides have also shown potential as therapeutic agents to support management of osteoarthritis and joint health. [viii] [ix]

Healthy gut.

Like our skin, the lining of our digestive tract is technically an external surface of the body. The lining acts as a vital barrier to protect us from pathogens and other substances. Thus, it’s important to keep it healthy and intact. The amino acids found in collagen are also uniquely supportive to the health and integrity of our digestive lining, not just our skin. [x]

It’s not just an old wives’ tale that soothing bone broth is a helpful method of easing illness and promoting the strength of our immune system (by way of a healthier gut).

Better sleep.

Few things can make us look or feel younger and more energetic than a solid night of sleep. And while there are hundreds of sleep remedies available — and dozens of over-the-counter medications that promise more restful sleep — what if a real solution could be part of your bedtime snack?

Choosing a Quality Collagen: 

With so many benefits, it’s important to choose a high-quality collagen supplement. When looking for a quality collagen supplement, Coach Anika recommends looking for one that has minimal (and recognizable) ingredients and is low in sugar. It should also be manufactured in a GMP-certified facility (GMP stamp should show on bottle) to verify its safety. While Coach Anika is a huge fan of our Chocolate- and Vanilla-flavored Collagen, she most recently enjoys our new flavorless Collagen that is now available online and launching in clubs later this month. The best part about this one? The unflavored supplement will make it easy to add to lower-protein foods such as organic, gluten-free oatmeal; coffee; and homemade soups.

If you’re just getting started with collagen, our coaches recommend taking 10 to 20 grams a day (½ to 1 scoop for 3 to 4 weeks) as this regimen is a good starting point to begin seeing changes. 

If you’re unsure about how to add collagen into your eating plan, try adding the powder supplement to some of the following foods and beverages:

  • Coffee and Smoothies
  • Desserts
  • Soups
  • Pasta Sauces 

While the ways you can add collagen into your eating plan are seemingly  limitless, be sure to check out some of our dietitians’ favorite collagen recipes here. If you discover any new ways to incorporate collagen into your diet, be sure to share your ideas with us!

Strength Training: Total Body vs. Splits

One of the most common questions I have heard in the 20+ years I’ve been in the fitness industry is, “Should I do total-body workouts or training splits (splits for short)?”  It doesn’t matter if it is asked from a fitness enthusiast who has been working out for six months or six-plus years, the question gets asked all the time, so I will answer it in this article.

A Beginner's Guide to Gluten Free Eating

It feels like these days, gluten has become the butt of a never-ending joke. In the past, the only people who knew what gluten was were those with Celiac disease – an autoimmune disorder that results in damage to the intestinal lining if gluten, a protein in wheat, rye and barely, is consumed. . These days it’s become one of many healthy food fads – with individuals boasting that they’re gluten-free while they reach for a stack of GF cookies – because it’s thought that “they’re healthy”. As a result, gluten sensitivities seem to be taken less seriously than other common sensitivities like dairy or soy. And while not every individual reacts negatively to gluten, the fact is that it’s still one of the most common – and under-estimated – sensitivities Americans experience today.

5 Beginner Foam Rolling Moves

Everyone can benefit from foam rolling.

Although popular with our fitness professionals, this tool might be one of the most underutilized pieces on our fitness floor.

Per Mitchell Keyes, master trainer with a credential in muscle activation therapy, “Foam rolling supports a technique, called self-myofascial release (SMR), that helps apply pressure to the tissues around your muscles.  This tissue can get tight (often called a trigger point or bundle of tissue) – whether from exercise, sitting all day or even wearing heels, etc. – so foam rolling helps to loosen it by breaking up that ‘bundle’.”

Which Type of Strength Training is Best for You?

Summer is over; fall is here. (Unfortunately, sooner than later — especially for people who live in Minnesota).  As the weather starts to cool off, more people will be headed indoors to clubs like Life Time. The indoor atmosphere offers an ideal space to take up resistance training.  But many members shy away from the weights because they don’t have the time, get bored or feel confused about how to maximize resistance-training benefits.

To prevent this from happening, there will be articles each month on how to get the most out of lifting weights.  This first article will discuss what Straight Sets, Pairs (also known as Super Sets) and Circuits are, and the pros/cons of each.
