Kayvan frames creatine supplementation as a dietary-gap decision rather than an automatic requirement. First assess whether red meat, which he identifies as a natural creatine source, appears regularly in the diet. Someone who routinely eats red meat may already obtain enough for a supplement to be less necessary. Someone who avoids red meat, including a person eating only chicken, turkey, salmon, or plant foods, falls on the supplement side of the rule. Kayvan then gives a simple daily dosing distinction: five grams for men and three grams for women. The output is a repeatable yes-or-no decision that can be revisited whenever eating habits change, rather than treating creatine as universally essential or universally unnecessary.
Origin
Liron Kayvan develops the rule while answering Jennifer Cohen's questions about who needs creatine, contrasting regular red-meat eaters with people whose diets provide little natural creatine.
Core principles
- 01Creatine is naturally present in red meat
- 02Supplementation is most useful when dietary creatine is limited
- 03Regular red-meat intake can reduce the need for a separate supplement
- 04Supplement doses should reflect the individual's diet and sex
How to run it
- 1
Audit red-meat intake
Check whether red meat is a regular part of the diet. Kayvan treats it as the main natural source relevant to the decision.
Pro tip Base the answer on a normal week rather than an unusual meal.
Watch out Do not equate eating other animal proteins with eating red meat for this specific rule.
- 2
Classify the dietary gap
If red meat is absent or infrequent, classify dietary creatine as limited. Plant-based diets and diets centred on chicken, turkey, or salmon fall into Kayvan's supplementation group.
Pro tip Reclassify whenever the underlying diet changes.
Watch out This is a general rule from the episode, not an individual medical assessment.
- 3
Apply the supplement decision
Supplement when red-meat intake is limited; treat supplementation as less necessary when red meat is eaten regularly.
Pro tip Use the dietary gap, not supplement popularity, as the trigger.
Watch out Less necessary does not mean medically prohibited.

Choose the stated dose
Kayvan recommends five grams for men and three grams for women in the low-red-meat group.
Watch out Seek professional guidance where health conditions, pregnancy, or medication make generic dosing inappropriate.
In the wild
Jennifer asks about someone who does not eat red meat but does eat chicken, turkey, or salmon. Kayvan puts that person on the supplement side of the rule and gives the daily sex-specific doses.
→ The decision is based on the missing red-meat source rather than whether the diet is technically omnivorous.
Kayvan says he does not take a creatine supplement because he eats meat. When Cohen clarifies that regular red-meat and animal-protein intake makes supplementation less necessary, he confirms her interpretation.
→ The person avoids treating an already supplied nutrient as an automatic extra purchase.
Common mistakes
Supplementing without checking the diet
The rule starts with dietary sources. Skipping that audit turns a conditional decision into an automatic one.
Counting every animal protein as red meat
Kayvan explicitly places chicken, turkey, and salmon eaters in the group that may still need supplementation.
Treating the rule as medical advice
The episode offers a general dietary heuristic and does not assess contraindications or individual clinical needs.
Is it for you?
Best for
It is best for adults who eat little or no red meat and are considering creatine for muscle or general health.
Not ideal for
It is not ideal for anyone who needs personalised medical or pregnancy guidance rather than a general dietary rule.
From the transcript
“the negatives for taking creatine is you don't need to all you need to do is eat red meat and eat enough red meat”
“the only reason why we need to supplement is because we're divorced from our natural habitat and our natural diet”
“definitely five grams for men three grams for women”
