In order to obtain prime health‚ your body depends on taking in the appropriate amount of vitamins‚ minerals‚ and nutrients as fuel that allows it to continue with its processes. Sometimes‚ it’s hard to know exactly how much of each nutrient your body is taking in. Nutrition facts on backs of food and drink products can only say so much‚ and sometimes it’s difficult to know exactly how much of a mineral or vitamin your body should be exposed to. While a deficiency in a nutrient can make someone feel disconnected‚ lethargic‚ and may lead to further health problems‚ an overabundance of too much of a nutrient may also not be optimal. So‚ how can you know precisely when and how much of an essential vitamin‚ like vitamin D3‚ you should be taking? The answer may lie in a dietary supplement that is a specific source of that vitamin.

D3 Serum by Premier Research Labs is a rich supply of live-source natural vitamin D3. This formula may help to support the cardiovascular and immune systems. The serum also may help with calcium absorption for strong bones and teeth. As a live-source D3 vitamin‚ this formula is absorbed by the body quickly.

What‚ though‚ is vitamin D3 exactly? Vitamin D3 may also be known as cholecalciferol‚ is simply a different form of the main vitamin D. Vitamin D has long been heralded as ‘the sunshine vitamin’. Rays from the sun absorbed into the body provide vitamin D. Vitamin D3‚ in a related sense‚ is produced photochemically in the skin.

D3 Serum has been rigorously tested with Premier Research Labs’ own Quantum Reflex Analysis 4-polarity testing system‚ which tests all 4 biofield polarities. In addition‚ this product is gluten-free‚ and contain liquids or oils that are 100% excipient free‚ meaning they have been submitted for tests that state they do not contain and toxic tagalong chemicals or agents in the formula.

Each 0.46oz bottle of Premier Research Lab’s D3 Serum has a recommended dosage of 1 drop daily taken with a meal‚ by inverting bottle at a 45 degree angle until a single drop emerges.

Premier Research Labs is proud to bring its cutting-edge and dynamic products to the world. The company has risen to the top of the industry to become an internationally known and universally respected vitamin and supplement manufacturer. It is also extremely honored to be the world’s first and only producer of cellular resonance products‚ which effectively restore quantum coherence to the body's biofield. Extensive clinical research has shown that once this restoration is complete‚ the body's healing power may be beyond limits; this is a power that can be gained with Premier Research Labs’ fine products.

      I like this vitamin D because it is inexpensive so it takes less to give you same effect. It keeps my Vitamin D level up and it is a solid product from premier labs. I do about 5 drops every morning.

      Pros

      For the price you get much more bang for your buck than other Vitamin D products. one drop equals 1000ml I take about 5 drops a every morning .

      Cons

      no cons so far.
      I would recommend this item to a friend.

      Faulty Bottle

      from BELLINGHAM WA on 7/13/2019
      Seems like a good product until the dropper fell apart . I picked up the bottle and the top of the dropper came off so the product went all over the floor. You wonder how good the product is when the dropper falls apart.

      Pros

      Didn't get to use it long enough as bottle fell apart..

      Cons

      Cheap bottle

      this is a tiny little dropper bottle, and was easy to use and lasts quite a while... you just have to be careful not to overdo because you only need a drop or two. I'm not sure if it's better absorbed in this form... it's a little messy and I think the gel tabs might be easier. But it was economical (and I save the little glass dropper bottle to use again... good recyclable!)

      Pros

      potency, price, bottle

      Cons

      I would recommend this item to a friend.

      Since I started using this oil, I haven't been sick, even when exposed to flu.

      Pros

      So easy to just drop in my orange juice of smoothie!!

      Cons

      I need to put a couple drops of orange oil on top of it, to get it to break down.

  • Question:
    I do not see an expiration date on the bottle. If stored properly, how long after bottle is opened does it expire?
    Michelle on 10/04/2017 Answer:
    • Hi Michelle, thank you for your question. The product does have a manufacture date rather than an expiration date. The manufacture date the product currently has is 04/17/2017. The expiration date is 3 years after the manufacturing date so the expiration date will be 04/17/2020. Hope this helps! Have a happy and healthy day!
