Ingredients

Quercetin
We source our quercetin from pagoda flowers. These flowers come from a tropical plant native to India and Southeast Asia. On its own, quercetin is very poorly absorbed.

Bromelain
A protein-digesting enzyme found in the fruit and stem of the pineapple plant. Most importantly, bromelain significantly enhances quercetin absorption, moving it from the digestive tract into the bloodstream more efficiently.

Zinc
A vital mineral for the activity of more than 300 enzymes. Zinc also aids in the body’s ability to heal wounds.

Vitamin C
An antioxidant that protects against cell damage and helps boost your immune system. Your body needs it to form blood vessels, cartilage, muscle, and bone collagen. It is also a vital ingredient in your body’s healing processes.

Vitamin D3
Well known for helping your body absorb calcium and phosphorus. Vitamin D3 may also help protect against respiratory infection. It is not found in many common foods. Though your body is capable of synthesizing Vitamin D3 through exposure to sunlight, many older adults do not get enough time in the sun to produce a sufficient amount. Studies estimate that a staggering 60% of nursing home residents and 57% of hospitalized adults are Vitamin D-deficient. The total number of Americans who suffer from Vitamin D deficiency has been shown to be as high as 42%. A common source of supplemental Vitamin D3 is irradiated and chemically processed wool grease, commonly known as lanolin. We only source our Vitamin D3 from hand-harvested lichen.

Vitamin K2
Regulates calcium deposition, promoting the calcification of bones and preventing the hardening of arteries and kidneys. The Vitamin K2 in our formula (MK-7) is more bioavailable and helps direct the calcium absorbed by Vitamin D3 to end up where you want it (your bones) and not where you don’t (your arteries and kidneys). There are very few sources of K2 in the typical Western diet. We source our K2 from natto, a well-known fermented Japanese superfood.

Note: Vitamins D3 and K2 are fat-soluble, and the human body absorbs them best when consumed with a meal.

Backed by Science

Quercetin is a well-studied plant flavonoid with documented antiviral and anti-inflammatory properties. It modulates key cellular signaling pathways and regulates immune responses [1]. However, quercetin has low oral bioavailability when taken alone. It is often paired with bromelain, a pineapple-derived proteolytic enzyme, which has been shown to improve quercetin absorption and enhance its therapeutic effects [2][3]. Zinc is an essential trace mineral critical for immune function, wound healing, and cellular repair. Even mild zinc deficiency can impair immune defense and inflammatory regulation [4]. Vitamin C supports both innate and adaptive immunity by maintaining epithelial barrier integrity, enhancing cellular immune responses, and acting as a potent antioxidant to neutralize reactive oxygen species [5]. Vitamin D3 plays a vital role not only in calcium metabolism and bone health but also as an immune modulator. Clinical studies indicate that adequate vitamin D3 levels may reduce the risk and severity of respiratory infections, particularly in older adults who commonly experience deficiency [6]. Vitamin K2 MK-7 is important for calcium metabolism by activating proteins that direct calcium deposition into bones and prevent arterial calcification, thus supporting cardiovascular and skeletal health [7]. Each ingredient in Immunity Vitamins is carefully selected in its most bioavailable form and combined in clinically supported ratios to maximize synergistic effects and health impact.

Women’s Health

Improved Brain Function: Creatine supports mental clarity, memory, and mood—particularly during hormonal shifts or low-estrogen phases such as perimenopause and menopause [1].

Increased Strength & Energy: Creatine enhances muscle tone, endurance, and recovery, even in low-intensity training, helping women maintain strength and vitality at any age [2].

Metabolism Support: By preserving lean muscle mass, creatine helps maintain a healthy metabolism, which naturally declines with age [3].

Supports Hormonal Health: Emerging research links creatine to improved mood regulation and hormone balance, offering relief from PMS symptoms and support during menopause [4].
