“I just became an expert in all things nutritional supplements. And I was just bothered by a lot of what I saw which got me kinda crazy enough to start a company in the space.” (09:55) (David)
“When you dive deep into the industry, unfortunately, you realize pretty quickly that it’s a very predatory industry. Unless a consumer has a background in nutritional science, they honestly have a zero percent chance of understanding what ingredients can benefit them, or what products can benefit them, because it’s super nuanced.” (11:31) (David)
“The vision was never, ‘Let’s be everything to everyone.’ The vision was more, ‘Let’s go into categories where we know we can make the best joint supplement, or immune supplement, or whatever it is, and have the clinical data to back it up.’” (16:04) (David)
“If they get to X million dollars in sales, they’ll just pay that two, three, four million dollar fine. And that’s just a business decision. I could tell you so many stories, which I’m a little hesitant to do because I don’t want to rip other companies, but this is actually like a business strategy in the industry. They go back to the predatory line of company profits and revenue matter more than consumer health, which is nuts. You can build a nice business by serving your customers really well with products of excellence.” (18:33) (David)
“Vitamin C is a good tell for me. Ascorbic acid is like the lower quality, least expensive form of Vitamin C. It can be harsher on your stomach. So mineral ascorbates have always been my preferred form of Vitamin C. It’s five to six times more expensive per kilo at the raw material level, but it’s less harsh on the stomach. The data shows your cells readily intake mineral ascorbates and get more out of it than just ascorbic acid.” (29:20) (David)
“I’ll also look at the ‘other ingredients’ for protein or meal replacement powders, because that’s where a lot gets hidden. I don’t want to see any gums because you can do it without gums. I don’t want to see any sugar alcohols because those spike a glycemic response in insulin production, which you do not want over time. I don’t want to see artificial anything. I don’t want to see artificial sweeteners. It’s just a tell-tale sign that a company is not doing it well. And so gums, sugar alcohols, preservatives, artificial anything would be things where I would say to avoid those products.” (31:46) (David)
“Children’s gummies drive me nuts, because I think they just have too much sugar or they don’t have enough [vitamin minerals] because it would taste so bad that they wouldn’t be able to sell it.” (46:57) (David)
