- Can vitamin A be toxic?
Good morning friends,
Vitamin A is often praised for supporting vision, skin health, and immunity.
But here’s what most people don’t realise - too much can harm you.
Why vitamin A toxicity happens
Unlike water-soluble vitamins, excess vitamin A isn’t flushed out easily.
Your body stores it in your liver and fat cells.
Over time, high levels can lead to:
• Dry skin and headaches
• Liver damage
• Weakened bones and osteoporosis
Your genes matter
Some people have variations in the BCMO1 gene that make it harder to process vitamin A efficiently.
For them, even moderate intake can push levels too high.
What the research shows
Chronic intake over 10,000 IU per day has been linked to:
• Liver problems
• Bone loss
• Birth defects during pregnancy
So what should you do?
This isn’t about avoiding vitamin A - it’s about personalised nutrition.
Know your genetics – Your DNA reveals how well you process vitamin A
Check your diet & supplements – You might be getting more than you think
Aim for balance – Enough to support health, but not enough to overload your system
When you understand your genetic blueprint, you stop guessing - and start eating in a way that works for your body.
