I noticed visible results in separate blood tests, so they definitely have a positive effect on my body in the long term and that's why I recommend them, but always keep in mind that there is a small chance that the absorption of the required vitamins from this particular supplement may not work similarly for you and your body may prefer another one.

Amazing next day delivery service to Paros. Product exactly as described and a couple of free gifts as a nice touch. Will use again for sure. Great job! .Thanks

It's as if I'm not taking them, my hands and feet hurt the same, also something very important is that since I've been taking them, my sweat smells, I never expected something like this... ☹️

Very good product, it did not cause me any digestive problems. However, the time it takes to dissolve sublingually is relatively long. Finally, my body could not absorb this supplement satisfactorily. After a three-month treatment, it went from 280 pg/mL to 350 pg/mL. Thus, I was forced to choose another company's B12 with which I saw a significant difference.

I don't know if it's the product's fault, but it did absolutely nothing for me. After 7 months with a doctor's prescription, my B12 was at rock bottom, which is why I changed companies and saw a difference. I wouldn't recommend it.

The only vitamin D3 that boosts my levels in the blood. According to the doctors I asked, the fact that it dissolves in the mouth (you suck the pill) and not in the stomach plays a role and gives you the maximum. Because I have a serious deficiency of the vitamin, I take these specific ones every 3 months and everything is fine.

After a doctor's recommendation, my parents are satisfied and have been using it for a long time. For dietary supplements, it is important to first consult your doctor.

Amazing vitamins! It does exactly what it promises and the taste is also pleasant! I highly recommend it with closed eyes!!

So I used this product, after a doctor's recommendation, because I was in a phase of physical and mental exhaustion. Trying other methods and formulations, always with a doctor's advice, I had no results, but trying this I saw improvement firstly in my hematocrit and overall in my endurance and mental clarity.

I have been using it for 6-7 months now! It is ideal especially for women entering menopause and also for afterwards! D3 and B12 levels drop significantly during this period. And so far, FORTIUS has been covering me!
