Vitamin D3 – Sunshine on Prescription?
About seven years ago, I stumbled across a YouTube video in Germany, that I still remember clearly: a lecture by Prof. Dr. Jörg Spitz titled "Vitamin D – Hype or Hope?"
That video was the start of a whole new understanding of health for me – and especially of a “vitamin” that isn’t really a vitamin at all, but a hormone: Vitamin D3.
What struck me most at the time was Prof. Spitz’s clear criticism of official recommendations. He showed how many public health statements on Vitamin D are misleading or just plain wrong. One example: some sources claimed that 15 minutes of outdoor time per day – even without direct sun exposure – would be enough.
But that’s been scientifically disproven. Without direct midday sunlight on your skin, your body produces almost no Vitamin D.
And here in the Philippines – where we practically have sunshine every day – I see the same problem. Many people, especially women, walk around with umbrellas to avoid tanning.
In Europe, it’s similar: sunscreen with SPF 30 or higher blocks almost all Vitamin D production – and that’s true for most of the year.
Back then, I started looking deeper. I checked blood levels, read studies, talked to doctors and natural health experts – and at some point, I realized: I have to take responsibility myself. For my health, and for my loved ones.
I don’t want to wait for someone else to tell me what’s “enough” – especially if that only means barely avoiding deficiency, not actually being healthy.
Today I know: if I want to feel better, think clearer, and stay physically fit, I can’t just hope for sunshine. I have to act.
If you really want to produce Vitamin D naturally, here’s what i advise you to do:
🔸 Go out in the midday sun between 11 am and 2 pm.
🔸 Expose as much skin as possible – ideally as much as you would in a bikini or swim shorts.
🔸 Stay in the sun for at least 20–30 minutes – depending on your skin type, up to 50 minutes.
🔸 And do it without sunscreen – otherwise, nothing happens in the body.
Of course, you should avoid getting sunburned. But there’s a natural trick: Lycopene, from tomatoes or carrots – or as a supplement – can help protect your skin from the inside out.
I take it regularly – along with Astaxanthin. Both are strong antioxidants and natural sun protectors.
Why I take Vitamin D3 every day
I don’t just take Vitamin D3 because of the sun – I’ve seen over the years how important it is for my >immune system,
>bones,
>muscles,
>heart,
and even my >mood.
I always combine it with Vitamin K2 – to make sure the calcium goes where it’s needed: into the bones, not into the arteries:
🔹 Vitamin D3 helps your body absorb more calcium from food into your bloodstream.
🔹 Vitamin K2 activates special proteins (like Osteocalcin and Matrix-GLA protein) that guide calcium into the bones – and keep it out of soft tissues and blood vessels.
Without this K2, Vitamin D3 can actually be problematic: it moves calcium into the bloodstream, but doesn’t direct where it should go.
That’s why D3 and K2 are a powerful team:
D3 gets calcium into play, K2 gets it to the right place.
That’s also why I now take a supplement that already combines all three in one capsule:
– 210 mg Calcium Carbonate,
– 100 mcg Vitamin K2,
– and 125 mcg Vitamin D3. (5000 IU)
I take 2 capsules daily – and feel like I’m always on the sunny side of life.
If you want to do something good for yourself – get your Vitamin D level tested. And make sure it’s in the optimal range.
Not too low – but also not too high.
