How to Use

As a supplement, adults may take 1 or 2 capsules per day with a meal. 

Calcium supplements may be taken in the morning or the afternoon with lots of water, but taking calcium in the morning gives individuals a chance to be exposed to more sunlight, allowing the skin to synthesize vitamin D, which further helps in Calcium absorption.

Other notes

Individuals taking medication should discuss potential interactions with their healthcare practitioner.

Woodstock Vitamins’ Calcium Concentrate is a multifaceted natural supplement. It contains the most bioavailable forms of three different essential minerals for proper bone growth and strength.

Calcium 550 mg per serving
Calcium is vital for skeletal nutrition and can have a dramatic impact on our overall health. By providing the building blocks for bones and teeth, Calcium ensures continued growth and formation of healthy bone structures through life stages. Calcium also plays an important role in muscle contraction and nerve signaling. It helps regulate blood pressure, assists in the release of hormones, and helps control body weight. The consumption of supplemental Calcium may reduce the risk of developing colorectal cancer and research continues to show evidence that it also has protective effects from illnesses such as osteoporosis.
Phosphorus ~200 mg per serving
Phosphorus is an essential mineral to the human body, and its ability to promote healthy bones is well-known. This micro-nutrient assists the body utilize and absorb Calcium more efficiently, improving overall bone strength and density. Phosphorus also impacts muscle health, allowing for improved physical strength and stamina. Individuals lacking adequate phosphorus in their diets may become more prone to fractures and find it difficult to power through endurance exercises like running or biking. Supplementing phosphorus can help improve your health and protect against long-term bone issues related to aging or injury.

Frequently Asked Questions

  • Why do I need a Calcium supplement?

    Calcium is an essential mineral that is necessary for bone health, muscle function, nerve function, and blood clotting. It’s the building block of bone. 

    With a deficit, deterioration is inevitable. Without adequate calcium intake, your body may begin to withdraw calcium from your bones, which can lead to weakened bones and an increased risk of fractures and osteoporosis.

    Everyone, specifically women, naturally loses bone density as a result of aging. Preventative care in a dietary supplemental form is the key to maintaining the best quality of life.

  • How is this different from other Calcium supplements?

    This calcium supplement contains microcrystalline hydroxyapatite concentrate (MCHC), a complex crystalline compound composed primarily of calcium, phosphorus, bioactive growth factors, type I collagen, amino acids, glycosaminoglycans, and a broad range of essential trace elements that naturally compromise healthy bone.

    Calcium Hydroxyapatite Concentrate 275 mg provides 1100 mg of MCHC per capsule to optimally support bone strength and structure.

    Our quality assurance promise takes all our products through the strictest quality control testing and methods, ensuring no detectable heavy metals like lead make their way into your calcium supplement.

    Other brands use fillers that dilute the potency of the product. At Woodstock Vitamins, you’ll only ever find the stuff that truly makes a difference. That’s why our Calcium Hydroxyapatite CaMCHA has only two ingredients.

  • How much Calcium do I need every day?

    You need about 1,000mg of calcium per day. You can get it from your diet by eating foods like dairy products, leafy greens, canned salmon with bones, and almonds. If you’re not getting enough calcium from your food, which most people don’t on a daily basis, you can also take a supplement.

    Calcium deficiency can lead to a variety of health issues and deficiencies. Supplementing with a daily dose of Calcium Hydroxyapatite is a recommended solution to ensure you’re getting the 1,000mg your body needs daily. 

    Studies have shown that this form of calcium supplement provides the essential nutrients for stronger teeth and bones, as well as better overall health. Calcium Hydroxyapatite can also improve joint flexibility and help prevent conditions like osteoporosis. Keeping up with adequate daily doses of this nutrient is an easy way to ensure your body gets what it needs for optimal wellness.

  • How is Woodstock Vitamins’ Calcium different?

    Calcium Hydroxyapatite is a unique form of calcium that’s easily and quickly absorbed by the body. It also contains phosphate, which helps to ensure proper mineral balance in your system. 

    Compared to other forms of calcium, such as Calcium Carbonate or citrate, Calcium Hydroxyapatite is better able to be used by the body for different metabolic processes such as skeletal mineralization, heart function, and nerve transmission. Additionally, since it’s easily absorbed, it reduces the risk of calcium buildup in the arteries and decreases the chance of getting certain types of kidney stones too.

  • What makes this product “Vitality Approved”?

    We keep wellness simple by adhering to the Supplement Quality standard. Through our strict third-party testing, our supplements are free of all contaminants and thoroughly batch-tested for quality and potency. 

    The primary contaminant found in calcium hydroxyapatite supplements is lead. Lead can enter the body through supplementation and is a strong neurotoxin, meaning it can affect the brain and nervous system. 

    Woodstock Vitamins only uses the cleanest, highest-quality ingredients through third-party testing to ensure purity, potency, and integrity. You can breathe easy knowing our formulas are developed with the latest cutting-edge scientific research to deliver efficiency, absorption, and results for women and men at all life stages.

  • What makes Calcium Hydroxyapatite the best option for me?

    If you’re looking for a way to maintain strong, healthy bones and teeth, Calcium Hydroxyapatite is likely the best option for you. Plus, maintain optimal mobility and flexibility while preventing bone loss, arthritis, and more.

%0D%0AI would have to put look up the exact date that I started Calcium from Woodstock. I would imagine it’s a year. I was happy that my last bone density was improved from the previous one. I also take it with vitamin d and magnesium and am very active. Woodstock makes it very easy. They ship fast%2C and I am confident in their knowledge and commitment.

This is the Correct Calcium Supplement for Your Bones

I need to take a calcium supplement not only because I am post menopause, but also to counter the side effect of a medication I take daily. I have taken this particular calcium for many years. I am happy to say my bone density tests which are taken every 2 years show that my bones are still strong.
