8 Top Trustworthy Supplement Brands (That You Should Use)

By Nick Urban from Outliyr.com

In true biohacker form, up until recently I started my day with a mountain of pills, powders, and capsules. That is legal dietary supplements, of course. One day I ran out of one product and bought a new brand. The product had the same dose but the capsule doubled in size. I investigated.

To my horror, I found 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 nor 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.


My research on the below companies comes mostly from their own websites along with third party evaluation,

Who 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 that don’t have to worry.

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 a 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 their rankings of products across 36 supplement categories.
