Pure D3 Liquid – Highly Absorbable Vitamin D3

YouTube video

Pure D3 Liquid contains the active form of Vitamin D (D3) which does not require sunlight for activation.

This form of D3 is ready to be used by the body and the liquid formulation in a micellized matrix makes absorption easy.

Each drop of Pure D3 Liquid contains 1,000 IU’s of Vitamin D3 which makes titration and dosing incredibly easy.

With up to 1 billion people worldwide who suffer from Vitamin D deficiency I consider Vitamin D supplementation to be a necessary supplement for most people (along with probiotics, fish oil, multivitamins, and adrenal support).

My own personal testing supports the fact that the vast majority of Americans are Vitamin D deficient whether they realize it or not.

I rarely ever find someone who has normal or healthy levels of Vitamin D when doing routine testing.

And this promotes a big problem for many people as the symptoms of Vitamin D deficiency can result in increased

Vitamin D3 Deficiency & Symptoms

Vitamin D Deficiency is associated with the following symptoms:

  • Depression
  • Increased risk of developing autoimmune disease
  • Brain fog
  • Weakened immune system
  • Bone loss
  • Sweaty head
  • Elevated thyroid antibodies
  • Hair loss
  • Muscle pain
  • Low energy

Many people who suffer from Vitamin D3 deficiency don’t even realize they have it.

They may just feel slightly fatigued, notice that they get sick more often than usual, or suffer from mild depression.

These symptoms can be masked until the right tests are ordered or until they start to supplement with D3.

How to Use Pure D3 Liquid

Dosing Pure D3 liquid is easy and depends on your serum levels of Vitamin D3.

Vitamin D3 is one of the very few fat-soluble vitamins (A, D, E, K) which means there is a theoretical risk of overdosing. Overdosing is not a risk unless you are using as much as 10,000 IU’s per day (or more).

Your body can also handle incredibly high doses of D3 at an infrequent rate (so the risk of overdosing is minimal). Sunlight, for instance, can provide up to 100,000 IU’s of D3 which the body can handle very well.

I recommend Vitamin D3 doses in the 1,000 to 2,000 IU per day range (this would be 1-2 drops per day with Pure D3 Liquid).

This will keep you safe from higher doses of Vitamin D3 which may lead to calcium dysregulation.

You should always attempt to get Vitamin D3 the natural way (from sunlight) even if you are using D3 supplements.

In addition, be sure to check your Vitamin D3 levels at least every 3-6 months to see if you need more or less.

Aim for a Vitamin D3 level in the 40-50 ng/ml range.
