Frequently Asked Questions
Can I Take Too Much Vitamin D?
Yes, although toxicity from hypervitaminosis D is very rare, and people are far more likely to be at risk from vitamin D deficiency. Sun exposure doesn’t lead to overdose because the body has its own defense mechanisms – burning and the pigment melanin prevent the skin from producing excessive vitamin D. Dietary sources and supplements in sensible doses are also safe. High doses of vitamin D with high calcium intake in the absence of Vitamin K2 should be avoided to ensure healthy blood calcium levels.
Can I Take Too Much Vitamin K2?
From the scientific literature to date there are no reports of Vitamin K2 toxicity. There is significant research that people are far more likely to be at risk from Vitamin K2 deficiency. Stick to natural vitamin K2, particularly in the MK-4 form, which is the most studied and what we have in our Athletic Greens®- Balanced Vitamin D3 and K2 Liquid, and avoid synthetic Vitamin K3.

Why Should We Take Vitamin D3 And Vitamin K2 Together?
This two nutrients work together synergistically in our bodies. Both work better as nutrients when the other is present. Taking Vitamin D and K2 can greatly support and enhance your overall health.

What Makes This Vitamins D & K2 Formula Unique From Others Currently Available?
Most other vitamins D and K2 supplements currently available do not provide the optimal levels of each nutrient, whereas Athletic Greens Balanced Vitamin D & K2 formula does: 10 drops provides 5,000 IU per day of vitamin D and 1000 mcg per day of vitamin K2. Because they are in drops, you can also easily titrate your dosage an intake. For example, w drops provides 1000 IU of Vitamin D and 200 mcg of Vitamin K2. These are the entry levels that research has shown to begin to be effective for supporting your overall health, including bone and heart health.* Of the few supplements that do have adequate levels of each nutrient, many use inferior forms of vitamin K2, as it is cheaper. We use MK-4, which is processed via bacterial fermentation, meaning that there is no soy in this product, and you getting the most studied and validated form of Vitamin K2 on the market.
