It depends. A variety of factors such as age, weight, skin color, and even geographical location affect the amount of Vitamin D a person needs. At the lower level, recommendations from The National Institutes Of Health and the Endocrine Society range from 400-2000 IU. Whereas a recent large-scale study from Germany recommends a much higher range. That’s why it’s best to discuss your Vitamin D needs with your healthcare provider, who has the full overview of your personal needs.

There is some debate about the optimal level of Vitamin D in the blood. For example, a study from the Boston University School of Medicine found a range of 40-60 ng/ml was needed to achieve the full range of health benefits conferred by Vitamin D. And another study from the University of California, found that a slightly higher range of 60-80 ng/ml was associated with even greater benefits. But ultimately, your optimal levels will depend on your current health status and health goals.

Most people with Vitamin D deficiency don’t notice any symptoms. That’s why it’s important to get tested. However potential signs of Vitamin D3 deficiency include muscle and bone pain, heightened sensitivity to pain, a tingling sensation in the hands or feet (often described as "pins-and-needles"), muscle weakness in areas close to the body's core such as the upper arms or thighs, a waddling gait caused by muscle weakness in the hips or legs, a history of previous bone fractures, muscle twitches or tremors, and muscle spasms.

Vitamin K2 plays a critical role in maintaining optimal bone health by supporting bone metabolism and mineralization. It activates osteocalcin, a protein responsible for binding calcium to the bone matrix, which enhances bone strength and reduces the risk of fractures, osteoporosis, and age-related bone loss. Additionally, Vitamin K2 helps regulate calcium distribution throughout the body, preventing calcium from accumulating in arteries and soft tissues. Directing calcium towards the bones and teeth instead, it supports cardiovascular health, reducing the risk of arterial calcification and cardiovascular disease. Furthermore, Vitamin K2 promotes dental health by facilitating proper mineralization of teeth and preventing tooth decay. It also shows potential benefits for cognitive function, as studies suggest it may protect against cognitive decline. Lastly, Vitamin K2 possesses antioxidant properties that help combat free radicals. By modulating oxidative stress, Vitamin K2 contributes to overall health and well-being. Whereas Vitamin K1, or phylloquinone, plays a vital role in blood clotting, bone health, cardiovascular health, and acts as an antioxidant.
