December 2014 There is a DNA sequence change in the CYP1A2 gene that is fairly common, with approximately 50% of the general population carrying at least one copy of the variant allele. February 2015 Twin studies find the heritability of caffeine-related traits to range between 0.36 and 0.58. The results strongly suggested that genetic variation of ADORA2A is a determinant of individual sensitivity to subjective and objective effects of caffeine on sleep. The longer the caffeine stays in circulation, the higher the risk of heart problems and hypertension. I'm interested in knowing more about people with Cytochrome P450 1F. I don't need the test. If I drink a cup of coffee even in the morning, I will lay awake all night. Caffeine is a popular stimulant present in coffee, certain teas, chocolate, energy drinks, colas, and some medications. Caffeine Metabolism and Sensitivity - Are They in Your Genes? Caffeine Problem #3: If you struggle with hormone imbalances (and if you’re reading this right now, you or someone you love probably does), it can be sign that your body has a hard time metabolizing caffeine. "An individual with caffeine sensitivity will experience [some of the symptoms listed below] or caffeine overdose symptoms with ingestion of as little as 100mg of caffeine… Am J Med Genet B Neuropsychiatr Genet 141B:634–636, Teucher B, Skinner J, Skidmore PM, Cassidy A, Fairweather-Tait SJ, Hooper L, Roe MA, Foxall R, Oyston SL, Cherkas LF, Perks UC, Spector TD, MacGregor AJ (2007) Dietary patterns and heritability of food choice in a UK female twin cohort.

Whether you feel good or not-so-good after eating or drinking caffeine is partly due to tolerance as well as factors like your age, whether you're male or female, and what medications you're taking. If you are a slower metabolizer, you will feel the effects of caffeine for a longer time.

Thats because while coffee is a readily available source of caffeine, its also a common culprit for unwanted side effects that go beyond the jitters. The “slow” genetic variant is associated with lower levels of the CYP1A2 enzyme and a slower rate of caffeine breakdown.
