The negative Primal Queen review I published recently was meant to be a one-off. But readers keep asking me about various bison, organ-meat, and “ancestral testosterone” brands they’ve come across in their feeds, and the pattern is the same: a cheap product sold with dishonest marketing and a visual identity that’s “borrowed” from better brands that are actually doing the hard work of sourcing and producing a quality supplement.

When I published my article on how I cured my IBS after three decades of bloating, constipation and abdominal pain, I expected some pushback. What I didn’t expect was how many readers would write back with a version of the same story: “I cut the plants and ramped up the meat like you suggested, and now I feel worse.

Primal Queen shows up in my inbox almost every week. Women want to know if it’s a real ancestral nutrition product or another well-marketed capsule with a famous founder story attached. That’s due in large part to the fact that the company spends an absurd amount of money advertising their product on Google and Meta; if you’ve searched for information on organ meat supplements, you’ve no doubt seen their many, many ads and sponsored products (as shown in the screenshot below).

I’ve owned and tested dozens of traditional and infrared saunas over the years, including Sunlighten’s mPulse Conquer Smart Sauna, which has been my go-to IR cabin since I first assembled it back in 2022. I’m still a big fan of the mPulse, which is the most feature-rich infrared sauna I’ve used to date.

I follow an animal-based diet, and I’m a big believer that eating nose-to-tail is the best way to get the nutrients my body needs to function optimally. But there’s one mineral I still supplement with every single day: magnesium. That might seem unnecessary on paper, considering that on a typical day I consume roughly 470 mg of magnesium from food – which is slightly above the current recommended daily allowance (RDA) of 420 mg for men. So why bother with a supplement?

Nordic Wave recently sent me three of their best-selling cold plunge tubs — the Viking Premier, the Viking Hybrid, and the Viking XL — and I’ve been testing them at my home spa alongside the company’s Gen 2 Pro chiller. In this review, I’ll share what I like about Nordic Wave’s tubs, what could be improved, and which of the three tubs I’ll keep. If you don’t have time to read the entire article, here are my key takeaways: The Viking XL is the one I’m keeping.

Chicken is widely promoted as a healthier alternative to red meat because it’s leaner and more affordable. Beef, by contrast, is often framed as indulgent or problematic, associated with rectal cancer, inflammation, cardiovascular disease risk and environmental concerns. The goal of an animal-based diet is to choose foods that deliver the most usable nutrition with the fewest trade-offs – i.e., to consume foods that support strength, metabolic health and long-term resilience.

Energy-efficient infrared saunas have gained popularity over the past few years due to their many health benefits and their relatively low maintenance requirements compared to traditional wet saunas. As I mentioned in my article about how to choose an infrared sauna, I’ve owned several different IR saunas at different price points, and I have researched and tested many more.

Bison organs are nutritional powerhouses that deliver whole-food vitamins, minerals, amino acids and peptides just as nature intended. What most people don’t know is that bison organs are also richer in many micronutrients than beef organs, lower in histamines, and offer more favorable fatty-acid profiles. The problem with bison organs (as well as bison meat) is that it’s more challenging to source, and it’s also more expensive.

I began tracking my workouts, recovery and sleep using WHOOP in 2019, and I learned a lot about how my lifestyle choices were impacting the quality of my sleep and my body’s ability to recover from daily stressors (including exercise). After several years of wearing WHOOP, I stumbled across the Ultrahuman Ring Air – a direct competitor to the more well-known Oura Ring (which I was wearing at the time).
