Everything is USDA Organic, vegan, and free of synthetic fillers.
What Is Garden of Life mykind Organics Plant Calcium?
Garden of Life is one of the largest certified organic supplement brands in the U.S., and their mykind Organics line represents their cleanest formulations. The Plant Calcium uses calcium derived from a species of red algae harvested from pristine ocean waters off the coast of Iceland. This isn’t the same as synthetic calcium carbonate (essentially ground limestone) found in most drugstore calcium supplements.
The algae naturally accumulate calcium and over 70 other trace minerals from seawater, creating a whole-food mineral complex. Garden of Life adds organic plant-sourced D3 (from lichen) and vegan K2 (MK-7 from natto) to create what many integrative practitioners consider the optimal bone support combination.
The product is USDA Organic, Non-GMO Project Verified, Certified Vegan, and Certified Gluten Free. For adults over 50 who read labels carefully and care about sourcing, these certifications carry real weight.
What’s Inside
Each three-tablet daily serving provides:
- 770mg of organic plant calcium (from Lithothamnion red algae)
- 800 IU vitamin D3 (from organic lichen — vegan source)
- 100mcg vitamin K2 (as MK-7 from organic natto)
- Organic whole-food blend including moringa, amla berry, turmeric, and holy basil
- 73 naturally occurring trace minerals from the algae matrix (magnesium, strontium, boron, silica, and others)
The trace mineral matrix is what sets algae-derived calcium apart from synthetic options. These co-occurring minerals may support how your body absorbs and utilizes the calcium. No calcium stearate, no titanium dioxide, no synthetic binders.
What the Research Says
The case for plant-derived calcium is growing. A 2009 study published in Nutrition Journal compared algae-derived calcium to calcium carbonate and found that the plant source maintained bone mineral density more effectively over a 2-year period. The researchers attributed this partly to the trace mineral complex.
Vitamin D3 is essential for calcium absorption — without adequate D3, your body absorbs only 10-15% of dietary calcium, compared to 30-40% with sufficient D3 levels. For adults over 50, D3 status tends to decline due to reduced skin synthesis and lower dietary intake, making supplementation particularly important.
The K2 component addresses a legitimate safety concern. A 2015 study in the journal Integrative Medicine found that K2 (MK-7) significantly reduced arterial stiffness and improved vascular elasticity. K2 activates matrix GLA protein, which keeps calcium in bones and out of arteries — an important consideration given the debate about calcium supplementation and cardiovascular risk.
Who Is This Best For?
Garden of Life mykind Organics Plant Calcium is an excellent fit if you:
- Prefer whole-food supplements over synthetic or isolated nutrients — the algae-derived calcium with its natural trace mineral matrix aligns with a whole-food philosophy
- Follow a vegan or plant-based diet — everything from the calcium to the D3 (lichen-sourced) to the K2 is completely plant-derived
- Care about organic certification — USDA Organic means no synthetic pesticides, herbicides, or GMO ingredients in the whole-food blend
- Want the D3 + K2 combination included rather than buying separate supplements — this simplifies your daily routine
- Have a sensitive stomach — many users find algae-derived calcium gentler than calcium carbonate, which can cause bloating and constipation
If you prefer fewer pills per day, New Chapter Bone Strength Take Care offers a similar whole-food approach with a slightly different algae source and requires fewer tablets.
How to Take It
Take three tablets daily, ideally split into two doses — two tablets with one meal and one with another. Your body absorbs calcium most efficiently in amounts of 500-600mg or less at a time, so splitting the dose improves utilization.
Timing tip: Take at least one dose with your largest meal of the day. The stomach acid produced during digestion helps with calcium absorption.
Interactions to watch: Separate calcium from thyroid medications (levothyroxine) by at least 4 hours. Space calcium at least 2 hours from antibiotics (tetracyclines, fluoroquinolones) and bisphosphonate bone drugs (alendronate). Calcium can reduce the absorption of these medications.
Always consult your doctor before starting calcium supplementation, especially if you take prescription medications, have kidney disease, or have a history of kidney stones.
The Bottom Line
Garden of Life mykind Organics Plant Calcium is our top pick for adults over 50 who want organic, whole-food bone support. The algae-derived calcium with its natural trace mineral matrix, combined with D3 and K2, represents what the latest bone health research supports. You’re paying more than you would for a bottle of calcium carbonate from the drugstore — but you’re getting a fundamentally different and arguably better product. The certifications are real, the sourcing is transparent, and the formula is designed the way integrative practitioners now recommend.
Frequently Asked Questions
Is plant-based calcium as effective as regular calcium supplements?
Research suggests it may actually be superior. Algae-derived calcium contains a natural matrix of 73 trace minerals alongside the calcium, which may support better absorption and utilization. A 2009 study in Nutrition Journal found that plant-sourced calcium (from the red algae Lithothamnion) produced better bone mineral density outcomes than calcium carbonate alone. The whole-food matrix appears to give your body calcium in a form it recognizes and uses more efficiently.
Why do I need vitamin K2 with my calcium supplement?
Vitamin K2 directs calcium to your bones and teeth — and away from your arteries. Without K2, supplemental calcium may deposit in soft tissues and blood vessels, which is why some studies have linked calcium-only supplementation to cardiovascular concerns. K2 activates osteocalcin (which builds bone) and matrix GLA protein (which prevents arterial calcification). The combination of calcium, D3, and K2 working together is what current bone health research supports.
How much calcium should a woman over 50 take daily?
The National Institutes of Health recommends 1,200mg of total calcium daily for women over 50 (from food plus supplements combined). Most women get 400-600mg from diet, so a supplement providing 600-800mg fills the gap. This product provides 770mg per daily serving, which pairs well with a calcium-containing diet. Taking more than 500-600mg at once reduces absorption, so splitting doses throughout the day is ideal.
Is this calcium supplement safe for people with kidney issues?
Anyone with kidney disease or a history of kidney stones should consult their doctor before taking calcium supplements. High-dose calcium can increase kidney stone risk in susceptible individuals. That said, plant-derived calcium may carry less risk than synthetic calcium carbonate because the trace mineral matrix supports more balanced mineral metabolism. Your doctor can advise on the right dose for your situation.
