Would love to see Swanson brands tested

[Thereshallbelight]

You are special! Helping millions of people from being scammed by cheaters!

NOW and Dr's Best are big quercetin sellers on Amazon, would have been nice to see those tested, or were they tested?

[MissLibertarian]

So, my question is, we’re these private labels being supplied by the same supplier(s)? Is this what happens when a label trusts but does not verify? Perhaps simply buys based on price? Who is committing this fraud? Clearly, there were no ties between percentages so maybe there are other variables such as quality of the source material.
This review is a real service and much better than anything involving politics.

Please include Swanson in some of your supplements analysis..since they are so popular.

[wingmannj]

why no test on the biggest sellers like now and doctor's best?

[mrmikeeu]

Don't know any of these brands. How about testing Swanson, Life Extension, Pure Encapsulations or Solgar.

[jstevens]

now I wonder if my Naturebell Magnesium Glycinate is a scam too. ugh...thanks for all the great work you do Ryker

[mjgrant]

i just love these lab test videos. but why were the big companies not included. these are the ones we really want to see.

[AlexRyan]

The amount of scamming is depressing.

How about we encourage Amazon to partner with these 3rd party labs to display the test results on the Amazon web page of the product?

This would clear out a lot of the scammers, right?

[neumeon]

I was hoping you would have tested the Solaray brand of Quercetin. I really appreciate these videos and the scientific method. I prefer not to have government regulation on these supplements, so this is where your analysis comes in and is so important! Cheers!

[bryanwelch]

These comparisons are much appreciated. Thank you for all your work!

[AlexRyan]

Ryker,

God bless you for quantifying the depth and breadth of the scamming in these videos.

You are doing God’s work.

I pray that this culminates in Amazon displaying the results of 3rd party testing for on the product page of each supplement.

This would get rid of most of the scammers.

[bigneocortex]

Do more vids like this! so many scam companies out there! Im shocked

[Brandall]

Thank you for your effort to expose these supplements. Will definitely try to use your affiliate links to support your work. There are probably many more brands you could test right? Also wish you had a summary chart at the end to summarize your findings.

[larryc]

More lab tests for all important supplements! Thank you!

[jackortega]

For future videos please consider including also these brands: solgar, igennus, Vegavero, WeightWorld
