Key Benefits and Actions*

  • Cost-efficient, potent dose in each easy-to-use drop
  • Simple, low-allergen potential formula
  • May help support bone health as part of a healthy diet rich in calcium and other minerals
  • May help support a healthy immune system

Optimal Vitamin D Liquid by Seeking Health provides a potent 50 mcg (2,000 IU) dose of vitamin D3 per drop, in pure olive oil base. Vitamin D is essential for the normal functioning of many important systems in the body and is needed to support a healthy immune system and long-term bone health. Many do not get sufficient vitamin D3 in their diet, and the synthetic vitamin D2 that is added to dairy products is not typically well-absorbed or included in sufficient amounts. Vitamin D3 occurs naturally in fatty fish, fish oil (especially cod liver oil), egg yolks, and beef liver. Optimal Vitamin D contains cholecalciferol derived from cholesterol in sheep’s wool, making it suitable for vegetarians.*

The amount of vitamin D3 that an individual needs varies due to a variety of factors. Some factors that contribute to vitamin D deficiency include spending most of the day indoors, using sunscreen, less sunny climates, or darker skin tone (melanin blocks UVB rays, which produce vitamin D in the skin).*

Vitamin D deficiency symptoms and individuals needs for this nutrient vary depending on the individual, so we recommend consulting with a physician or qualified healthcare professional for testing prior to using a high-potency vitamin D supplement. The liquid format of Optimal Vitamin D makes it easy to tailor the dose to fit your specific needs, and may be easier to take than capsules or softgels for some individuals. Optimal Vitamin D is free from artificial fillers, flow agents, preservatives, or flavors.*

For a higher dose of vitamin D in a convenient capsule format, consider our Vitamin D3 5000 IU.

Always be sure to follow your healthcare provider’s instructions first and foremost, and ask for testing to determine what your current levels are.

Life Changing

I'm not exaggerating when I say that adding this vitamin to my family's daily routine has changed our lives. Last winter we were sick from November to March straight with colds, the flu, bronchitis, pneumonia, sinus infections, etc. It was miserable. This year around the end of the summer my daughter got croup and I decided enough is enough. My chiropractor recommended we try vitamin D so we added it and it helped. It wasn't until I came across Dr. Lynch's protocol for not getting sick that we realized how magical it is! It is the end of January now and I'm thrilled to say that not a single member of my six person family has caught anything so far! All of our friends have had colds and the flu and we've been exposed countless times, but we bump up our vitamin D intake and we're fine!

Helps to heal dry skin

I've noticed when I take this consistently every day, some of the dry skin around my nose clears up. Also, I've avoided at least 3 colds this winter already and I give this Vit D part of the credit! Also, it's a great price for such a high quality item!
