The answer is yes!

Vitamin K2 menaquinone 7 is very safe as a food additive.

2000 mg/kg/day orally, no poisoning symptoms.
The rats were fed MK-7 for 90 days, and the biochemical, blood, urine parameters, and histopathological analysis proved its safety.
Genetic toxicity and mutagenicity of the Salmonella typhoid strain showed that this ingredient had cell safety and non-mutagenicity.

No adverse effects after taking vitamin K2 MK-7.

The potential toxicity of vitamin K (K1 and K2) is very low.
The American Food and Nutrition Commission FNB has not established the maximum tolerable intake of vitamin K2.
FNB pointed out that “no adverse effects have been reported in humans or animals after taking vitamin K2 from food or supplements.”

In 2017, the United States Pharmacopoeia Committee and reputable review agencies (such as the European Food Safety Agency, the British Vitamin and Mineral Expert Group, the National Academy of Sciences, and the World Health Organization) reviewed the clinical and nonclinical research data related to MK-7 in recent years and reached conclusions.

Influencing Factors Of Vitamin K2 Stability

Light

The production and storage process of VK2 shall be as dark as possible because K2 is sensitive to light. The main attention is to avoid light as much as possible during weighing and production, or it is recommended to use a pink light source with a longer wavelength in the operation room to reduce the photodegradation of K2.

Vitamin K2 Formula

VK2 and some minerals will degrade in the tablets after being pressed, and magnesium oxide and calcium citrate are the most serious ones.
Calcium carbonate can be recommended when designing the formula for calcium DK tablets.
Magnesium (especially magnesium oxide) should be avoided in the formula design of multi-vitamin-mineral tablets.

Menaquinone 7 Production Process
