Perfect for busy adults with limited sun exposure (hello, office warriors!), those in cloudy climates, or anyone boosting immunity and bones daily.

How much Vitamin D3 is in each softgel, and is it enough?

Each delivers a solid 1,000 IU. That's about 10-20 minutes of midday sun exposure! If deficient, stack with your doctor's guidance.

How does one bottle last, and is it worth it?

60 softgels = 2 months of daily goodness. At this price, it's a steal for premium Swiss quality.
