FAQs

Sharp pressure on the lower part of the head and pain on my front-head
I bought a suplement of Vitamin D3 10,000 IU + K2 200mcg Drops – MCT Coconut Oil Formula. Only had it once, 6 drops diluted in water following the instructions. After 3-4 hours, I increasingly felt a sharp pressure at the back of the lower part of my head and pain on my front head that last until the following day; it was a similar feeling to high blood pressure but without heart palpitations.
I was worried. I had been medically prescribed Vit D before in a higher dose but in a different format “ hidropherol” which did not have a side effect.
It might be an isolated case but thought to share in case another person had the same symptoms. I decided to stop taking it. See less
Hi there,
Thank you for sharing your experience — I'm really sorry to hear you felt unwell after taking the drops.
Your safety is our top priority, and I want to address your concern. While our Vitamin D3 + K2 formula is well-tolerated by the vast majority of customers, individual reactions can occasionally occur depending on factors like sensitivity to specific ingredients, existing health conditions, or interactions with other supplements or medications.
The symptoms you describe — head pressure and frontal headache — are not a recognised side effect of Vitamin D3 or K2 at standard doses, but everyone's body responds differently, and I'd strongly recommend discussing this with your GP, especially since you've been prescribed Vitamin D in a different form before. They'll be best placed to advise whether the MCT coconut oil base or the specific formulation may have been a factor.
Wishing you all the best
Good taste and I feel better.
I feel amazing. Better than supermarket brands.
High-quality supplement
I switched to these drops after struggling with vitamin D tablets, and I’m so glad I did. The absorption feels much better, and the peppermint flavor makes it pleasant to take!
These drops are highly effective, with a refreshing peppermint flavor that makes them a pleasure to take. They support both bone and heart health, providing an easy and tasty way to get your daily dose of essential vitamins.

The 3DK2 tastes delicious
Both my partner and I have felt an increase in energy and this is just days after we first started. Considering we last saw the sun on the 8th of Jan 2026 it has been a pleasant and much needed addition to our day! Love the positive reviews and really great value. Look forward to experiencing the long term benefits.
I bought 4 bottles of this for my brother as requested, so I think this product is good.
Straightforward purchase and delivery on time.
Am hoping that the drops are actually as described on label and in the listing. Obviously there is no way of knowing and only time will tell regarding health benefits. One can only hope it is genuine. If so this offer was great value for money.
Never heard of this company before. 🤷🏼
Nice having it
