Shine Bright With Essential Support

Vitamin D3 (cholecalciferol) Vitamin D plays an important role in bone health, heart health and immune support while working with vitamin K to support normal absorption of calcium and promote healthy arteries. Vitamin D is a fat-soluble vitamin that is found in some foods and endogenously produced when sunlight strikes the skin and activates vitamin D synthesis.

Frequently Asked Questions

  • Some studies have concluded that vitamin K2 does not interfere with anticoagulant medications; however, most products containing vitamin K (including K1 and/or K2) warn users taking anticoagulants not to take the product. If you are currently taking warfarin or another anticoagulant medication, you should consult your physician before taking any product containing vitamin K1 or K2.

  • One serving daily of Isotonix Vitamin D with K2 is recommended. Check with your physician before taking additional daily servings of this product.

  • Foods rich in vitamin D include cod liver oil, salmon, mackerel and tuna.

  • Studies have shown that healthy adults taking 125 mcg of vitamin D daily for extended periods rarely experience toxicity, as long as blood calcium and vitamin D levels are monitored.

My Vit D Review

Love the product it has brought my Vit D levels up , however, I am not a fan of the 90 day bottle shape - I'm in a humid climate and putting it into the cap isn't feasable so I use a 1/2 tsp - but it's hard to get accurate dosing this way -would love a wider opening. The product itself is awesome.
