Your 5-Step “Never Damage Your Organs” Checklist

  1. Get blood work FIRST
    – Liver panel (ALT, AST, GGT)
    – Kidney panel (creatinine, eGFR)
    – Vitamin D, iron, calcium levels
  2. Choose third-party tested brands
    Look for seals: USP, NSF, ConsumerLab, Informed-Choice
  3. Read the label like your life depends on it
    Short ingredient list = safer
    Avoid anything with artificial dyes, hydrogenated oils, or “proprietary blends”
  4. Dose like a drug — because many supplements ARE drugs
    Never exceed the upper tolerable limit without a doctor
  5. Re-test every 3–6 months if you take anything daily

Real-Life Wake-Up Calls

  • 46-year-old gym-goer: 4,000 IU vitamin D + red yeast rice daily → liver enzymes 15× normal, nearly needed transplant
  • 38-year-old woman: green tea extract for weight loss → acute liver failure, saved only by emergency transplant
  • 62-year-old man: cheap fish oil contaminated with mercury → kidney function dropped 40% in 18 months

Bottom line: Supplements are not “harmless” just because they’re sold over the counter.
Your liver and kidneys have no voice — but they’re screaming when you overload them.

Get the blood tests. Choose clean brands. Or better yet — fix most deficiencies with food and sunlight first.

Your organs will thank you for the rest of your life.
