Omega-3 Calculator
Find your daily recommended omega-3 fatty acid intake based on sex. Use it to assess whether your diet or supplementation meets the adequate intake (AI) for heart and brain health.
Daily Omega-3 Requirement
1.6 grams
At 1.6 g/day this matches the NIH Adequate Intake for adult men, roughly 45% higher than the female target of 1.1 g. Two oily-fish meals per week typically meets it.
Thresholds reflect the U.S. NIH/Institute of Medicine Adequate Intake (AI) for ALA omega-3: 1.6 g/day for men and 1.1 g/day for women.
TDEE Calculator
Convert your basal metabolic rate (BMR) into total daily energy expenditure (TDEE) by multiplying by an activity factor. The single number to eat at for maintenance, to subtract from for fat loss, or to add to for muscle gain.
