Ever spent a long time in front of the supplement aisle at the pharmacy?

"Vitamin D? Omega-3? Probiotics? Do I need all of these?" "So many brands, and prices vary widely..."

Ask ChatGPT or Claude about your situation, and it'll pick the right supplements and even create comparison charts!

Today, I'll show you how to smartly choose supplements using AI.

Why AI Supplement Recommendations are Useful

Ever stood in front of the pharmacy supplement section? Vitamins alone go from A, B, C, D, E... covering the whole alphabet, with dozens of products for each. Even multivitamins come in men's, women's, 50+, prenatal... Which one should you choose?

When you ask the pharmacist, they say "You need all of them," but buying everything would easily exceed 100,000 won per month. Search online and opinions are divided. "Vitamin D is essential!", "Must take Omega-3!", "Probiotics are important too!"... You end up more confused.

Moreover, it's hard to immediately feel the effects of supplements. Unlike medicine with instant effects, you wonder "Is this even working?" After taking them for 1-2 months, you often just throw them away. The money wasted this way amounts to hundreds of thousands of won annually.

AI solves this problem. It analyzes your situation to select only truly necessary supplements and even sets priorities.

Benefits

1. Personalized Recommendations - Your Prescription Customized to your age, gender, and lifestyle. A 20-year-old male athlete and a 50-year-old female office worker need completely different supplements. The former needs protein and creatine, while the latter prioritizes calcium and vitamin D. AI accurately distinguishes these differences.

2. Comparison Analysis - Objective Evaluation Objectively compares multiple products. Even for the same vitamin D, there are 10+ brands with 2x price differences and varying potencies. When AI organizes this in a table, you can compare at a glance.

3. Priority Organization - From First Priority Presents the order of what to take first. If your budget is 50,000 won monthly, it's better to properly take 3 truly necessary items rather than a little of 10 items. AI sets priorities like "1st: Multivitamin, 2nd: Vitamin D, 3rd: Omega-3."

4. Cost Optimization - Budget Customization Creates effective combinations within budget. If you ask "Can I do it with 30,000 won monthly?", it switches to value products instead of expensive brands and leaves only what's truly necessary. Save money while maintaining effectiveness.
