7 Top Trustworthy Supplement Brands (That You Should Use)

Until recently, I started my day with a mountain of pills, powders, and capsules.

One day I ran out of a product and bought a new brand. The product had the same dose but the capsule doubled in size. I investigated.

Each new capsule contained fillers, excipients, and plenty of other inactive ingredients. The first product didn’t have them, so surely the second cheaper brand didn’t need them either.

It turns out that not all supplement brands or products are the same. Choosing reliable brands ensures that you receive a product with the actual active ingredients inside, no questionable fillers, and most importantly, no contaminants.

In this post I will present the best supplement brands that meet the highest purity, safety, and trustworthiness standards:

• Certified by one of more regulatory agencies
• Vigorous safety testing
• Trusted by medical practitioners
• Minimal filler
• Products mostly made in the USA

The Wrong Supplement Manufacturer Are Worse Than Useless

Dietary supplements do not fit into the category of either food or drug, so the FDA turns a blind eye. Manufacturers notoriously cut corners whenever possible for a leg up on their rivals.

Filling this need, third-party companies evaluate products for effectiveness and safety.

Every year new headlines come out about contaminated supplements. The results of many such tests are dismal.

A study on athletes found that supplement users unintentionally consumed products adulterated with banned substances. This devastated the career of Olympic swimmer Jessica Hardy. And Jessica was proactive. Before buying she had contacted the company for safety and purity information on their products. Not an athlete?

Smart drugs, or brain-enhancing nootropics have similar issues with purity. Memory supplements contained little to no active ingredients, yet substantial contamination.

One of the larger tests of 138 common dietary supplements found worrisome levels of toxic molds, yeast, and fungi.

Another more recent 2018 study identified unapproved pharmaceutical ingredients in a staggering 776 dietary supplements. What kind of products? Those marketed for sexual enhancement, weight loss, or muscle building. From that same report:

“157 products (20.2%) contained more than 1 unapproved ingredient.”

It still happens today.

In June 2019 the FDA seized 300,000 containers of contaminated products.

Due to widespread product contamination and new untested brands bombarding store shelves, choosing a safe and reliable supplement brand is critical to your health and wellbeing.

The Best Honest Supplement Companies

My research on the below companies comes mostly from their own websites along with personal testing and third-party evaluation.

Note that I haven’t included all supplement vendors below, rather only the biggest and most popular.

These online supplement sellers don’t stock everything. For niche supplements, check out these posts:

There are lots of other great supplement brands and manufacturers. These are the ones I have the most experience with.

Supplement Brands I Stopped Recommending

While many top manufacturers used to create high-quality products, as in all industries, ownership often changes.

Pure Encapsulations

As their name implies, people chose Pure Encapsulations (PE) for their extreme attention to both safety and quality. You knew exactly what you get from Pure products. If you have lots of allergies, sensitivities, or concern over quality look no further.

I stopped recommending them because they were purchased by Nestle and we have little to no insight if any of their formulas or processes have changed (as they often do when companies are sold).

Garden of Life

Another company purchased by Nestle years ago, that was once known for whole-food-based nutrition. I’ve examined the labels of a number of their products and was unimpressed to now find all kinds of excipients, flow agents, binders, and other unhealthy (and unnecessary) additives.

How To Verify Supplement Quality

No matter what company you choose, give their products a thorough evaluation. There are a few criteria that all quality supplement companies have in common.

Quality Control Certification

Manufacturers should test the raw ingredients before they produce their formulation. Look for a third-party inspection certification. The best common supplement certifications include USP and NSF.

Certain products like fish oil have their own certifications. In the case of fish oil, look for IFOS.

Reputable companies will often provide you with Certificates of Analysis (CoAs) of their final product when asked.

Check The Ingredients Label

Capsule and pill fillers can unnecessarily interfere with absorption, and cause reactions in sensitive individuals. High-quality products minimize or do not contain “inactive ingredients”.

Passes Third Party Testing

Labdoor and ConsumerLab both independently test products for purity and safety. They purchase the supplements themselves and run unbiased testing.

ConsumerLab subscribers can access thousands of reports but they also publish some for free. Labdoor, on the other hand, publicizes its rankings of products across 36 supplement categories.

You can find the two here:

• ConsumerLab
• Labdoor

Which Supplement Brand Will You Choose Next?

Brands change fast in the supplement world, which is why I prefer the ones with a long, proven track record. Their products have stood the test of time and have raving fans.

The more products you add, the more opportunity for contamination. Choosing from the above quality brands reduces that risk so you don’t have to worry.
