Vitamin D3 Serum - Liquid Vitamin D Oil Drops for Adults, Liquid Vitamin D3 5000 IU, Sublingual Vit D3 Liquid - 0.43 fl oz

Was recommended by a doctor. Easy to use, just a couple of drops per day to stabilize vitamin D levels. The product is great, but the price has gone up so much over the last couple of years

Excellent product that raises D# levels fast. Great in winter.

Best source of vitamin D3; it’s in a base of olive oil oil most other vitamin D’s are in a base of medium chain triglycerides

Tasteless easy to digest

This D3 serum is a good product. I used it on my scar on my face. Worked well to help heal it.

This is the only D that will keep my levels up. Premier supplements are really great quality.

This is the only vitamin D I can take that doesn’t give me a headache. It actually raises your Vitamin D level as opposed to tablets that never worked. Easy to measure out and no after taste. Highly recommend.

Good product.
