Overjoyed with my results Woohoo! My vitamin D levels went up 58% in 5 weeks!!! I used it 6 days a week. This is HUGE because NONE of the vitamin D supplements I’ve taken over the last 25 years have helped increase my levels. FINALLY something is going in the right direction. I am seeing an associated decrease in inflammation too. As D goes up inflammation goes down. Yay! 😃 💃🏻 PS. Though I don’t take a vitamin D supplement anymore, I still take K2 to get the full benefit.

Extremely happy with my vitamin D lamp Extremely happy with my vitamin D lamp. My daughter has been very sick for 2 years with severe vitamin D deficiency. We are looking forward to her next blood work after using the lamp. I also use it everyday for 5 minutes. It was a great purchase- would have never known about it- but a doctor suggested it.

Everything was straightforward Everything was straightforward. The 15% discount is what made me "pull the trigger". Haven't yet been able to determine whether my vitamin D levels have increased. Have only been using it a couple of weeks.

Yes! 🌞 We had snow in Berlin this past Monday, 1 week short of May 🙃… so, I bit the bullet and ordered the Sperti half-a-year earlier than planned. I’ll probably purchase the Fiji as well. I’m very grateful to have a healthier, more natural alternative to supplements! Quick delivery + the product was in perfect condition.

I love the Sperti vitamin D lamp I love the Sperti vitamin D lamp! It’s easy to use and set up! I have consistently low vitamin d blood levels, and although I just started using it and I’m looking forward to improved vitamin D levels!
