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. Vitamin D toxicity is very rare and usually occurs with much higher doses (more than 250 mcg per day) over long periods.

Sugary supplement

It contains sugar, fructose, and maltodextrin which are not good for health. Especially with people who had diabetes.

Response from Customer Service:

Thank you so much for your feedback on Isotonix® Vitamin D with K2. We truly appreciate you taking the time to share your thoughts with us.

The small amount of sugar included in Isotonix products is necessary to facilitate our unique isotonic delivery system, which helps maximize nutrient absorption. Please be assured that we strive to source the highest quality ingredients for our customers’ well-being.

We understand your concern, especially when it comes to managing conditions like diabetes. We always recommend that individuals with medical conditions or those taking medication consult their treating physician before starting any new supplement. Only your healthcare provider can determine what’s appropriate for your specific needs.

For diabetic patients, if their physician approves the use of Isotonix products, we suggest they consider replacing a serving of fruit with a serving of Isotonix, as guided by their physician. Ultimately, your healthcare provider is the best resource when it comes to managing your dietary needs.

Thank you again for your feedback. If you have any further questions or need more information, please feel free to reach out.

Great product

Just add water and mixes itself. I cannot take vitamin D in pill form, harsh on my stomach. This is very gentle and apparently works very well as shown in my bloodwork results! So glad this product exists and known by my doctor who recommended this product to me.

A must have.

In my household Vitamin D has to be a staple. I don't notice it so much in myself, but my 19 year old son is a completelyl different (more pleasant) person when he's taking Vitamin D. Tastes great.
