Creatine is a foundational supplement for men that offers benefits for brain health, heart health, and muscle growth.

“Creatine is amazing. It's a longevity supplement. It's good for your brain. It's good for your heart. It helps build muscle indirectly. Probably assists with fat loss.”

Creatine supplementation can improve exercise training volume and may provide cognitive benefits, particularly under conditions of stress like sleep deprivation.

“having the creatine stores higher in your muscle is beneficial because one, you're going to be able to increase your training volume, right? So it's not like creatine is anabolic in the sense that protein or amino acids are, right? It's not like directly affecting muscle protein synthesis.”

Creatine is useful for males because it supports mitochondrial function and does not cause hair loss.

“Hair loss is not a reason to avoid taking creatine. It think of it as just bringing you to what you are naturally inclined to have.”

Supplements are merely training wheels that help the body learn processes and are not strictly necessary once an individual reaches a certain level of health and nervous system regulation.

“Ask not what your supplement can do for you, but what you can do for your supplement. I'm the supplement guy, and I'm going to tell you that you don't need supplements. The supplements are the training wheels.”

Most supplements are overrated for health-conscious people compared to fundamentals like sleep, stress management, and consistent training.

“But, supplements are just not in the conversation for important things that health-conscious people should have in even in their top 10 of important things they need to do. The top 10 important things are like getting adequate sleep, managing your stress really well, consistently lifting weights”

Supplements should be used as a secondary support to a whole foods diet, and people should avoid products with unnecessary fillers or additives.

“you want to have as least fillers and attit in that supplement is possible”

Supplements should be evaluated using a clear framework of potential risks and rewards because geroprotective efficacy is currently hard to measure.

“I think we have to acknowledge that there's a great uncertainty with many of these things, and therefore, we should ask ourselves, like, how can we handicap the risk based on human data, animal data, safety data, efficacy data as far as reward, and where on that matrix do we place this intervention?”

The supplement industry preys on insecurities and lacks adequate regulation, leading to products that often contain inaccurate ingredients or harmful substances.

“My big big problem is that these supplement companies prey on what our insecurities are. that we want to be skinnier, we want to be stronger, we want to have better sex, whatever it is. They prey on our insecurities.”

Tim Ferriss advises treating ketone monoester supplementation with caution because of mounting evidence suggesting it can be unhealthy for the liver in high doses.

“There's mounting evidence that it's pretty unhealthy for your liver. So just use in moderation in terms of ketone supplementation.”
