Why CalDveg

Unived’s CalDveg is a holistic bone-health formulation that provides more than just calcium, but also includes algae magnesium & 73 trace minerals, as well as vegan vitamins C, D3 & K2-7 to ensure calcium absorption & utilization.

Each serving of Unived CalDveg delivers 500mg of organic algae calcium derived from a plant-based source known as Algas calcareas, which also contains natural occurring magnesium and 73 trace minerals. Additionally, 30mg of plant-based vitamin C, 1000 I.U. of plant-based vitamin D3 (from Lichen, Vitashine) and 50mcg of natural vitamin K2-7 (as Menaquinone Mk2-7) are present with each serving.

Unived CalDveg is inspired by the role that bones play in our every day life. Loss of bone and muscle health can impact your entire physiology predisposing the body to bone health conditions such as osteoporosis, fractures and cardiovascular disorders. With CalDveg you may prevent such disorders and support healthy bone ageing throughout your adult life.

Algal Calcium VS Limestone Calcium

Algae calcium functions more holistically than traditional calcium. While regular calcium supplements merely slow bone loss[3] to an extent, algae calcium contributes by increasing bone density.[4]

Algal calcium is a superior, more effective and reliable alternative to traditional calcium products, a majority of which contain calcium carbonate and calcium citrate – mostly derived from marble and limestone.

Vitamin K2-7 and the Calcium Paradox

Did you know that your bones are highly dependent upon Vitamin K 2-7 for growth, development and maintenance? Bones can never achieve complete nutrition unless you supplement them with enough vitamin K2-7. Also without vitamin K2-7 you are putting your heart in grave danger. In a phenomenon called the ‘Calcium Paradox’, the lack of calcium in the bones correlates strongly with the deposition of calcium in the arteries. Vitamin K2-7 is needed to activate bone proteins such as osteocalcin[6], essential to bind calcium effectively to the bone matrix, keeping bones dense and strong. Shortage in vitamin K2-7 means that proteins such as osteocalcin are not able to perform their function and the calcium is lost into the blood stream instead of being deposited onto the bones. The result is a simultaneous increase in the risk of osteoporosis and calcification of the arteries.[7]

D3 is better than D2

Unived’s CalDveg is made using 1000 I.U. of vitamin D3, which readily binds with vitamin D receptors and effectively maximises calcium absorption (near 100% absorption as opposed to 2% in most popular calcium supplements).

  • Among the two chemically distinct forms of vitamin D, vitamin D3 is proven to be more potent as compared with vitamin D2.[8]
  • Vitamin D2 has less affinity for VDR (vitamin D receptor) and shorter shelf life in your body, than vitamin D3.[8]

Unived derives its vitamin D3 from lichen extracts –the only purely vegetarian and vegan source of D3 or cholecalciferol, the biologically active form of vitamin D.

Food Based Vitamin C

Vitamin C plays an integral part in collage formation. Collagen actually makes up 30% of our bones. It is particularly abundant in the connective tissue of cartilage and bone. Vitamin C also stimulates the cells that build bone, enhance calcium absorption, and enhance vitamin D’s effect on bone metabolism. Each serving of CalDveg includes 30mg of plant-based vitamin C, derived from organic cold pressed acerola juice powder.

Therapeutic dosages

It is well established that most commercial calcium supplements taken singularly do more harm than good and a balance of composite nutrition is essential for optimum bone health. Unived’s CalDveg contains a balanced dosage of all the elements necessary for your bones including 500mg organic algal calcium, 33mg organic algal magnesium, 30mg plant-based vitamin C, 1000 I.U. plant based vitamin D3 & 50mcg vitamin  K2-7 and other trace minerals. Compared to other calcium supplements, CalDveg is more bio-available and made for maximum absorption and utilization.

Suggested use

As a dietary supplement, Unived recommends a daily dose of 2 capsules for adults.

Take 1 capsule after lunch and 1 capsule after dinner. It is not recommended to consume both capsules at the same time. For optimal results and better bio-availability, it is recommended that the dose is split.

If you are taking iron supplements, please avoid taking CalDveg at the same time as taking iron. There should be a minimum of a two hour gap between taking iron and calcium.

What is CalDveg

Unived’s CalDveg

For good health and steady functioning of bones adequate nutrition is essential. Optimum bone health rests on a group of nutrients that work in consonance to improve skeletal health and keep the multiple diseases (especially of ageing) at bay. Several nutrients and dietary components including macronutrients, micronutrients and bioactive food ingredients can influence bone health.[10]

Unived’s CalDveg is made with a holistic approach towards repairing damaged bones, as well as preventing disease. Nutrition is always a balanced influx of multiple nutrients and it is especially true of bone health. We not only ensure you get enough calcium, magnesium and other minerals but also facilitate their absorption and utilization. Vitamin D3 and K2-7 play an important role in this.

CalDveg is made for complete bone fortification.


Your body needs calcium for various functions including strengthening of bones and teeth, blood clotting and cardiovascular and neurological functioning. Your bones and teeth store ninety-nine percent of the calcium and the rest is present in blood and tissues.[11]

  • Calcium is required for vascular contraction vasodilation, muscle function, nerve transmission, intracellular signaling and hormonal secretion, though less than 1% of total body calcium is needed to support these critical metabolic functions.[12]
  • Symptoms of hypocalcaemia (calcium deficiency) include numbness and tingling in the fingers, muscle cramps, convulsions, lethargy poor appetite, and abnormal heart rhythms.

Vitamin D3

Sunshine vitamin is a popular connotation for vitamin D. You need vitamin D, to make sure that you absorb enough total quantum of calcium.[13]

  • Vitamin D is mostly important for its function to maintain calcium and phosphorus balance and to facilitate infusion of minerals in the bones.[14]
  • Vitamin D deficiency results in abnormalities in both calcium and phosphorus metabolism.[14]
  • Calcium absorption by the intestine can be optimized with sufficient vitamin D levels. With deficient vitamin D levels, 10-15% of (dietary) calcium is absorbed by the intestine while 30% absorption is found with sufficient vitamin D levels. The calcium absorption goes up to 60-80% during growth, pregnancy or lactation due to increased demand for calcium.[14]
  • Vitamin D deficiency may affect fracture risk through several different mechanisms.[15]

Vitamin K2-7

Vitamin K is a unique nutrient produced within the body. However, it is not produced by the body but by beneficial microorganisms in the intestine. The vitamin produced in this manner is in fact 75% of what the body absorbs whereas the other 25% is attained from external sources. Once absorbed it equals the minimum quantity required for normal bodily functioning. Experts strongly recommend vitamin K2 supplements to help ensure bone and heart health.

  • Vitamin K2 is needed to activate a specific bone protein called osteocalcin, which is essential to bind calcium effectively to the bone matrix, keeping the bones dense and strong.[6]
  • Vitamin K2 is an important inducer of bone mineralization in osteoblasts.[6]
  • While calcium is essential for good health, irregularities in calcium metabolism can lead to osteoporosis and cardio-vascular disease. Vitamin K2 is emerging as a key factor in regulating calcium in the body.[16]
  • Insufficient vitamin K2 leads to decreased bone mineral density, a key factor in osteoporosis, and an excess of calcium in the arterial wall, which increases the risk of heart disease.[16]
  • In Japan, vitamin K2 has been shown to substantially improve osteoporosis when given either as a high-dose prescription agent or in the staple Japanese dish called natto, which is particularly rich in K2.[16]
  • Studies have also shown that even modest amounts of vitamin K2 fight heart disease by controlling calcium-regulating proteins in vascular tissue, which keeps calcium out of the arteries and prevents the formation of dangerous calcified plaques.[16]


Magnesium and other trace minerals are also extremely essential for bone fortification, and deposition & utilization of minerals

  • Algae calcium is the best available natural and organic source of magnesium which is essential to maintain bone mineral density and deficient levels are linked with osteoporosis.[2],[19]

Algal calcium + Vitamin C + Vitamin D3 + Vitamin K2-7 + Magnesium

  • Increases the production of Osteocalcin by the Osteoblasts (bone forming cells).
  • Is necessary to activate Osteocalcin – the protein that binds calcium effectively to the bone.
  • Inhibits the production of osteoclasts (bone-destroying cells).
  • Effectively brings about calcium deposition on the bone.
  • Supports collagen formation.


Poor bone health is mostly a result of nutritional deficiencies particularly of calcium, vitamin D, vitamin K and other minerals like phosphorus and magnesium. Maintaining a strong durable skeletal health can be a complex process. You require the right amount of bone mass, structure and composition. Several factors come into play, as both environment as well as your genetic makeup contributes to bone health. The right combination is key. Bone building typically exceeds bone destruction in healthy persons who get enough calcium intake and exercise. After that, destruction becomes the more prominent process.[11]

  • Health practitioners have noticed in recent times that due to poor lifestyle, people are unable to reach their peak BMD at 30. Due to this they came across more cases of weak bones in patients in their 20s.[18]
  • Factors such as poor posture, sedentary lifestyle and strenuous workouts or lack of them, high stress, poor diet, excessive smoking and drinking, overdose of caffeine and colas and hormonal imbalance are all contributors to poor bone health.[18]
  • Your body needs calcium for various functions including strengthening of bones and teeth, blood clotting, cardiovascular and neurological. Your bones and teeth store ninety-nine percent of the calcium and the rest is present in blood and tissues.[11]
  • Vitamin D insufficiency affects almost 50% of the population worldwide. An estimated 1 billion people worldwide, across all ethnicities and age groups, have a vitamin D deficiency.[19]
  • Several human trials have found vitamin K2 effective in the treatment of osteoporosis.[20]
  • Clinical studies establish the necessity of trace elements for optimal bone matrix development and bone density sustenance.[21]


Several reasons make women more vulnerable to bone related disorders as compared to men. For one, they tend to have smaller and thinner bones. Estrogen, a hormone with a protective effect on bones, reduces sharply post menopause, which increases their chance of getting osteoporosis.[22]

  • Younger women (in their 20s, 30s and 40s) are also seen to be affected by bone loss and diagnosed as suffering from osteoporosis.[22]
  • Reduced estrogen production increases bone loss and reduces calcium absorption.[25] In the five to seven years post menopause, women may lose about 20% of their bone density.[22]
  • Research acknowledges the beneficial effects of vitamin D on chronic diseases such as type II diabetes and depression in women.[26]
  • Breastfeeding can have serious implications on the bone development and bone health of the infant and the mother.[27] Full breastfeeding is associated with nearly 200mg/day of calcium outflow from mother to infant – a considerable portion of the mother’s daily requirement.[27]

Unived’s CalDveg helps by avoiding bone loss as well as strengthening your bones. Regular consumption not only supplies your bones with requisite nutrition but also ensures its effective absorption and utilization. It is suitable for young women, expecting, pregnant and breastfeeding mothers as well as postmenopausal women who undergo hormone related bone loss. CalDveg is derived from natural and plant based ingredients that are replete with nutrition and have no side effects. It is safe for long term use.


Men tend to have sturdier bones than women yet they too are susceptible to risk factors leading to bone loss.

  • Estrogen is found to be relevant for the bone health of men as higher levels are associated with higher bone density while lower levels, with low bone density.[28]
  • One in 12 men suffer from osteoporosis which can lead to serious and disabling consequences including fractures of the spine, hip and wrist.[28]
  • Both men and women lose bone mass at the same rate by the age of 65 or 70 and the calcium absorption also reduces.[29]

Unived’s CalDveg brings the requisite nutrition for strong bones. The essential minerals and vitamins D and K, promote bone forming cells to be active and prevent bone loss consistently. Being a balanced bone health supplement, CalDveg not only prevents bone related disorders like osteoporosis but also averts calcification of arteries that occur due to inappropriate supplementation.


Humans are the only species on the planet that consume milk beyond infancy and as adults. In fact a large number of individuals tend to stop producing lactase the enzyme required to digest milk, as they mature.[30]

  • About 75% of the world’s human population is intolerant to lactose and the intolerance results in symptoms such as diarrhea, abdominal pain, flatulence and nausea.[31]
  • Studies show that vegetarians absorb and retain more calcium from foods than non-vegetarians do.[32]
  • Most commercially available calcium supplements are made from animal sources such as oyster shell or inorganic sources including calcium carbonate and calcium citrate.

Unived’s CalDveg is a vegan supplement and contains no animal based ingredients. Unived vouches for complete bone health encompassing all the essential nutrients including calcium, vitamin C, vitamin D3, vitamin K2, and magnesium and trace minerals.

Ageing adults

Men and women begin experiencing bone loss in their 40s. However, women experience a rapid phase of loss during the first 5–10 years after menopause, due to the loss of estrogen. In men, this phase is obscure, since there is only a slow and progressive decline in sex steroid production; hence, the loss of bone in men is linear and slower.


Why do I need supplements to keep my bones strong?

In the nascent stages of bone formation, the creation of bone exceeds the destruction of bone. Your bones continue to be built in this manner until you pass the age of thirty. Beyond that the bone formation becomes lesser than the bone destruction. This leads to the corrosion of your bones and you end up with weaker bones. Weak bones are an open invitation for bone related diseases such as osteoporosis and osteoarthritis.

To ensure a healthy bone building process and prevent your bones from weakening and being afflicted by disease, you need an appropriate combination of the right nutrients. Calcium, vitamin D3 and vitamin K2-7 are all needed for intake, absorption and utilization of minerals for good bones. You need to supplement your bones with all these essential nutrients. That is why Unived’s CalDveg is an ideal supplement for your bones. It contains all the nutrients needed for optimum bone development and healthy bone ageing.

I take calcium every day. Isn’t that enough for good bone health? Why do I need anything else?

Good bone health requires all the essential nutrients necessary for growth and development of your skeleton. Calcium although important is only one aspect of this process. You also need other nutrients such as vitamin D and vitamin K to ensure that the calcium and other minerals are absorbed and utilized in order to strengthen your bones. In fact taking calcium singularly can be a major health risk as it may deposit on your arteries and may

Bone health is primarily a concern for old people. Do young men and women need to worry?

Bone building is a lifetime process although it is more pronounced in the developmental phase during childhood and youth. That is why it is important to ensure that children and young adults get all the essential nutrition. Up until midlife, it is important to make sure that your bones get the minerals, protein and vitamins they need so that your bones will have developed into a sturdy framework for you to rely on in the later years of your life. This way the bones can reach their optimum growth and minimize the risk of being afflicted by bone related disorders such as osteoporosis, and fractures in later life. This way, when you are older you run lesser risk of disease and frailty. Continue to nourish your bones as you age, to counter the bone loss that occurs during that phase of life. You need to replenish your bones with calcium, magnesium and other trace minerals, and vitamins D3 and K2-7 throughout your life.

What is wrong with the calcium supplements with calcium carbonate or calcium citrate?

Most commercially available calcium supplements contain calcium in the form of calcium carbonate and calcium citrate. These types of calcium are derived from materials such as limestone and marble. These are basically inorganic forms of calcium and are inefficiently absorbed and the calcium is never put to the use for which it is meant. Instead, it remains in the blood and eventually causes kidney stones or even worse deposits on your arteries hardening them and increasing the risk for stroke and heart attacks.

How is Unived’s CalDveg any different?

Unived’s CalDveg is important for your bones as it contains Algae calcium which is highly absorbable (nearly 80%) and also contains magnesium and other trace minerals for bone fortification. These essential minerals are combined with the goodness of vitamins D3 and K2-7 which ensure the absorption and utilization of calcium. This means that your bones have all the nutrition they need. CalDveg not only delivers the essential nutrients, but also makes sure that they are effectively utilized to make your bones strong and healthy for the long term.

Why do I need vitamin D3 and Vitamin K2-7?

Vitamin D3 is required to process the calcium we obtain from diet and supplements. It is required to facilitate the natural process of intestinal absorption of calcium so that it can be utilized for the bones. It also contributes by maintaining the calcium/phosphorus balance in the body and by facilitating infusion of minerals in the bones. Vitamin K 2-7 plays a role in activation of specific vitamin K dependent proteins (such as osteocalcin) which promote deposition of calcium on bones and prevent calcification of arteries and blood vessels.

How is D3 different from D2?

Vitamin D3, also called cholecalciferol, is the active form of vitamin D. It is proven to be more potent as compared with vitamin D2. It has more half-life as compared with D2. In clinical terms, this means that it stays in the body longer than vitamin D2. Vitamin D3 also has more affinity to the vitamin D receptors present in several major organs of the body. Unived uses vitamin D derived from lichens, the only completely natural and vegan/vegetarian source of vitamin D3.

What is the difference between vitamin K1 and K2-7?

Vitamin K1 is primarily known for its role in blood clotting. Vitamin K2-7 on the other hand is proven to positively influence bone health. It is associated with increase in Bone Mineral Density (BMD) and reduced fractures. Also, vitamin K2 has better ‘half-life’ as compared with vitamin K1. Vitamin K2-7 plays a role in activation of specific vitamin K dependent proteins (such as osteocalcin) which promote deposition of calcium on bones and prevents calcification of arteries and blood vessels.

Is CalDveg safe?

CalDveg is derived from all natural and nutrient rich sources. It does not contain any synthetic preservatives or additives. It has no know side-effects and is safe for life long use.

Note: If you are taking iron supplements, avoid taking CalDveg and your iron supplements at the same time, as calcium can interfere with iron absorption.

How much and how often do I need CalDveg?

You need to nourish your bones throughout your life. Each serving of CalDveg offers 500mg of natural plant based nutrients for nourishing your bones including calcium, magnesium, vitamins D3 and K2-7 and trace minerals. Unived recommends two capsules per day.

We recommend that you split the dose by taking one capsule after lunch and one after dinner for optimal results and better bioavailability.
