Biohack is an iOS app that scores every meal for longevity. It tracks 23 nutrients linked to healthy aging, provides AI-powered coaching, and helps you eat to live longer. It is made by Buettner Labs LLC.

How does Biohack score meals?

Biohack uses AI to analyze your meal (via photo, text description, or barcode scan) and scores it on a 0 to 10 longevity scale. The score is based on peer-reviewed longevity research and evaluates micronutrients, polyphenols, Omega-3 ratios, and other factors that matter for healthy aging.

What nutrients does Biohack track?

Biohack tracks 23 longevity-relevant nutrients including Omega-3 fatty acids, magnesium, Vitamin D, polyphenols, fiber, zinc, selenium, and more. It goes beyond calories and protein to focus on the micronutrients that scientific research links to healthy aging and disease prevention.

How much does Biohack cost?

Biohack offers a 14-day free trial, no credit card required. After that, Biohack Full Access is $12.99/month or $89.99/year.

How is Biohack different from calorie counters?

Unlike calorie counters that focus on calories and macros, Biohack scores meals for longevity by tracking 23 micronutrients linked to healthy aging. It provides AI coaching that identifies nutrient gaps and recommends specific foods and supplements based on your personal patterns.

Does Biohack work with intermittent fasting?

Yes, Biohack includes a built-in fasting timer that tracks your eating window and shows when autophagy (your body's cellular repair process) kicks in. It integrates fasting with your nutrition data for a complete longevity picture.

What countries is Biohack available in?

Biohack is currently available on the Apple App Store in the United States, Canada, Australia, New Zealand, the United Kingdom, and Germany. More countries will be added in the future.

Minerals

Zinc

The immune mineral that declines with age.

Zinc is required for over 300 enzymes and is central to immune function, wound healing, and DNA synthesis. Zinc deficiency accelerates immune aging (immunosenescence) and increases susceptibility to infections. The Zn-Age study showed that zinc supplementation in elderly adults reduced infection rates by over 66% compared to placebo.

Dosage

RDA: 11mg for men, 8mg for women

Optimal for longevity: Researchers recommend 15-30mg daily for older adults, balanced with copper to avoid depletion.

Deficiency signs

~12% of the US population is at risk of zinc deficiency; rates are higher in older adults

Frequent colds and infections
Slow wound healing
Loss of taste or smell
Hair loss
Poor appetite

Top food sources

Oysters (3 oz)74mg

Beef chuck roast (3 oz)7mg

Pumpkin seeds (1 oz)2.2mg

Lentils, cooked (1 cup)2.5mg
