How does the AI recognize food?

Our AI uses advanced computer vision trained on millions of food images. It can identify individual ingredients, portion sizes, and even complex dishes from restaurants worldwide.

Absolutely. Your food photos are processed securely and never shared. We use end-to-end encryption and comply with GDPR and CCPA regulations.

How accurate is the calorie tracking?

Our AI achieves 98% accuracy on standard meals, verified by certified nutritionists. For complex or unusual dishes, accuracy is still above 90%.

Can I use it for specific diets?

Yes! Caloria supports keto, vegan, paleo, Mediterranean, and many other dietary patterns. You can set custom macro targets to match any diet plan.

What's included in Premium?

Premium gives you unlimited meal scans, detailed macro tracking, personalized insights, weekly nutrition reports, priority AI processing, and data export capabilities.

Which devices are supported?

Caloria is available on iOS (iPhone and iPad). Android support is coming soon. Your data syncs seamlessly across all your Apple devices.

Is it better to take vitamins in the morning or at night?

It depends on the vitamin. B vitamins and vitamin C are best taken in the morning as they support energy metabolism. Fat-soluble vitamins (A, D, E, K) can be taken with any fat-containing meal, including dinner. Magnesium is most useful taken 1 hour before bed to support sleep.

Should vitamins be taken with food or on an empty stomach?

Fat-soluble vitamins (A, D, E, K) must be taken with a meal containing dietary fat for proper absorption. Water-soluble vitamins (B complex, vitamin C) can be taken with or without food, though food reduces stomach upset. Iron absorbs best on an empty stomach but can cause nausea, so a small snack is acceptable.

What vitamins should not be taken together?

Calcium and iron should never be taken at the same time — calcium reduces iron absorption by up to 62%. Zinc and iron also compete for absorption. High-dose zinc over time can deplete copper. Space these supplements at least 2 hours apart.

Can you take all your vitamins at once?

You can take most vitamins together, but some minerals compete for absorption. The safest approach is a morning stack (B vitamins, vitamin C, iron if needed) and an evening stack (vitamin D, K2, E, A, magnesium, omega-3). This separation avoids calcium-iron and zinc-iron conflicts.

Does the time you take vitamins affect absorption?

Yes, significantly for some supplements. A 2010 study published in the Journal of Bone and Mineral Research found that taking vitamin D with the largest meal of the day raised blood levels by approximately 50% compared to taking it fasting. Iron absorbs roughly 30% better on an empty stomach with vitamin C than with calcium-rich foods.
