    Heart health

    We pair our Vitamin D tablets with Vitamin K2 because K2 makes sure calcium ends up in bones and not in your arteries where it can cause heart problems.

  • image description

    Bone Strength

    Magnesium is essential for bone health as it aids in calcium absorption and is a component of the bone matrix.

    Vitamin K2 directs calcium to the bones, preventing its unwanted accumulation in soft tissues and aiding in bone strength. It also activates osteocalcin, a protein crucial for bone mineralization.

    Improved sleep

    ZMA, a potent blend of zinc, magnesium, and vitamin B6, is celebrated for enhancing sleep quality. Magnesium, a core component, promotes deep, restorative sleep by boosting the calming neurotransmitter GABA, making it easier to drift off. Additionally, the synergistic action of ZMA's ingredients supports hormone balance, including melatonin, the body's natural sleep inducer. Many users report deeper, more rejuvenating sleep, punctuated by vivid dreams, suggesting increased REM sleep—a hallmark of quality rest.

    Power anti inflammatory

    Chronic inflammation can lead to various health issues, including heart disease, diabetes, and autoimmune disorders. Vitamin D, Zinc and Quercetin are all power anti inflammatory supplements.

ABOUT EACH Supplement

Vitamin D3

Vitamin D3 is the form of vitamin D that our bodies produce naturally in response to sunlight exposure, particularly ultraviolet B (UVB) rays.


Bone Health: Vitamin D3 plays a critical role in calcium absorption from the gut, essential for maintaining healthy bones and teeth. It supports bone growth and remodeling, helping to prevent fragility and fractures.

Immune System: It has a regulatory effect on the immune system, enhancing the pathogen-fighting effects of monocytes and macrophages and decreasing inflammation.

Mood Regulation: Some studies suggest that vitamin D3 can help regulate mood and may play a role in warding off depression.

Other Roles: D3 is also believed to support brain and nervous system health, support lung function and cardiovascular health, and influence the expression of genes involved in cancer development.

Deficiency: A deficiency in vitamin D3 can lead to various health issues:

In adults, a lack of D3 can result in osteoporosis (decreased bone density) and osteomalacia (softening of bones).

Other symptoms can include muscle weakness, mood disturbances, and increased susceptibility to certain diseases due to compromised immune function.

Supplementation: Given that many people, especially those in less sunny climates or those who spend much of their time indoors, may not get enough sunlight for adequate D3 production, supplements can be useful.

Vitamin K2

Vitamin K2 is essential for bone health and cardiovascular health. It helps direct calcium to where it's needed, such as bones and teeth, and away from places it's not, like arteries and soft tissues. By doing so, it aids in preventing calcium deposits in arteries, which could lead to heart disease.


Quercetin is a naturally occurring antioxidant found in many fruits, vegetables, leaves, and grains. It's one of the most abundant antioxidants in the human diet and offers various health benefits:

Antioxidant Properties: Quercetin has strong antioxidant properties, which means it can combat free radicals in the body. Free radicals are unstable molecules that can damage cells and contribute to aging and diseases like cancer.

Anti-inflammatory Effects: It has been shown to reduce inflammation, which can be beneficial in conditions characterized by inflammation such as arthritis, heart disease, and certain skin disorders.

Heart Health: Some studies have suggested that quercetin can help lower blood pressure and reduce the risk of heart disease by improving blood vessel function.

Allergy Relief: Quercetin is known to stabilize the cells that release histamine in the body, potentially providing relief from allergies. This has made it a popular natural remedy for seasonal allergies.

Antiviral Properties: Preliminary research indicates that quercetin may have antiviral properties against various viruses, including respiratory syncytial virus (RSV) and even some forms of the flu.

Brain Health: It might have neuroprotective effects, potentially helping to shield the brain from the effects of inflammation and neurodegenerative diseases.

Sources: Foods rich in quercetin include onions, apples, grapes, berries, broccoli, citrus fruits, and even green and black tea.

Zinc & Quercetin Combination

Quercitin increases the uptake of zinc and making it more effective.

When you catch a virus, once it’s in cells it deploys something called replicase to hijack the cell's ribosomes.

Ribosomes are the cell’s production factory.
If the virus takes over control, it will get your body to make more viruses instead of things like proteins needed by the body.

However, in the event that zinc is able to enter the cell with the help of Quercitin , zinc’s anti-inflammatory prevents the virus from reproducing.


ZMA contains 3 ingredients

  • Zinc
  • Magnesium
  • Vitamin B6

Zinc Benefits

Immune Function: Zinc is crucial for the development and function of immune cells, such as neutrophils and natural killer cells. It can help bolster the immune system and may reduce the duration of cold symptoms when taken early on.

Protein Synthesis and Cellular Health: Zinc plays a role in protein synthesis, cell division, and DNA synthesis, all of which are vital processes for growth and repair.

Wound Healing: Zinc aids in inflammation control, immune function, and collagen synthesis, which are important for wound healing.

Metabolism: Zinc is involved in the activity of over 300 enzymes that aid in metabolism, digestion, nerve function, and many other processes.

Taste and Smell: It's essential for the proper development and function of cells mediating taste and smell.

Vision: Zinc is present in high concentrations in the eye, particularly the retina, and plays a pivotal role in maintaining vision.

Reproductive Health: Zinc is crucial for testosterone synthesis and is involved in various aspects of the male and female reproductive systems.

Bone Health: Zinc plays a role in bone formation and mineralization, which are critical for maintaining bone strength and health.

Skin Health: Due to its role in cell growth and replication, zinc is beneficial for maintaining the health of the skin and can be found in various skincare products.

Antioxidant: Zinc acts as an antioxidant, neutralizing free radicals that can cause cellular damage and contribute to aging and various health conditions.

Mental Health: There's evidence to suggest that zinc has neuroprotective properties and can influence mood. Deficiencies might be linked to mood disturbances or cognitive decline.

Blood Sugar Control: Zinc is believed to play a role in insulin production and storage, potentially influencing blood sugar control in people with type 2 diabetes.


Magnesium is an essential mineral that plays a vital role in a wide range of physiological processes. Here are some of its notable benefits:

Energy Production: Magnesium is crucial for converting food into energy. It participates in the reactions that generate ATP, the primary energy molecule in cells.

Protein Synthesis: It plays a role in the process of protein formation by assisting in the linkage of amino acids.

Muscle Function: Magnesium is necessary for proper muscle contraction and relaxation. It helps stabilize the amount of potassium inside and outside of muscle cells.

Bone Health: About 60% of the body's magnesium is stored in the bones. It is vital for bone formation and maintaining bone density.

Nerve Function: It assists in the transmission of nerve impulses and helps maintain the electrical charge of cells, especially in neurons.

Mood and Brain Health: Magnesium plays a role in brain function and mood regulation. There's evidence to suggest that adequate magnesium levels can help with mood disorders, and some forms of magnesium are used as supplements for brain health.

Heart Health: Magnesium contributes to a regular heartbeat by helping to transport other electrolytes (like calcium and potassium) into cells. It's also linked to a lower risk of atherosclerosis and hypertension.

Blood Sugar Regulation: Magnesium plays a role in insulin metabolism and can influence the release and activity of insulin, thereby helping control blood sugar levels.

Digestion: Magnesium helps the body produce enzymes that break down food and aids in other processes in the stomach and intestines.

Relief from Constipation: Magnesium can draw water into the intestines, which can help soften stools and promote bowel movements.

Anti-inflammatory Benefits: Some studies suggest that higher magnesium intake is associated with a reduced inflammatory marker level, which could be beneficial for conditions characterized by inflammation.

Migraine Relief: There is evidence to suggest that people who suffer from migraines might have lower magnesium levels. Some studies show that magnesium supplementation can help reduce the frequency of migraines.

Reduction of Muscle Cramps: Due to its role in muscle relaxation, magnesium can help alleviate muscle cramps and spasms.

Vitamin B6

Here are a few of the most important benefits of Vitamin B6 (pyridoxine):

Neurotransmitter Production: Vitamin B6 is crucial for the synthesis of neurotransmitters like serotonin and dopamine, which regulate mood and brain function.

Amino Acid Metabolism: It plays a key role in the metabolism of amino acids, essential for protein synthesis and overall cellular function.

Energy Production: Vitamin B6 helps release energy from stored carbohydrates and fats, aiding in glucose production.

Hemoglobin Production: It's involved in producing hemoglobin, which carries oxygen in the blood, supporting overall circulatory health.

Immune Function: Vitamin B6 supports the immune system by promoting the health of lymphoid organs where immune cells are produced.
