AlgaeCal Plus – Plant-Based Calcium Supplement with Vitamin D3

AlgaeCal Plus is a plant-based calcium supplement made from South American red algae (Mesophyllum superpositum) instead of ground rock. Each daily dose delivers 720 mg of algae-sourced calcium along with vitamin D3, vitamin K2 (MK-7), magnesium, boron, vitamin C, and 13 naturally occurring trace minerals that support bone density and skeletal strength.

Most calcium supplements come from crushed limestone or marble. AlgaeCal Plus takes a different route — it starts as a living marine plant. The algae is harvested, sun-dried, and milled into a fine powder that still carries the full mineral profile it built up in the ocean, so your body is absorbing a food-based form of calcium rather than a mined mineral.

Why AlgaeCal Plus Is Different

Calcium on its own doesn't do much for bone density if the body has nowhere to send it. AlgaeCal Plus is built around that gap:

• Whole-food calcium — sourced from red marine algae, not limestone, so it's chemically closer to the calcium found in vegetables like broccoli or kale.

• 13 bone-supporting trace minerals — including magnesium, zinc, boron, manganese, and strontium, all occurring naturally in the algae rather than added synthetically.

• Vitamin D3 — helps the body actually absorb the calcium it's taking in.

• Vitamin K2 (as MK-7) — works to direct calcium toward the bones instead of soft tissue like arteries.

• Vitamin C — supports collagen production, which forms the structural framework bone is built on.

• Lower daily dose, same clinical target — 720 mg per day, in line with the amount used in published human studies, rather than the 1,200 mg+ found in many traditional calcium products.

What's Inside (Per Daily Serving – 4 Capsules)

Other ingredients: vegetable cellulose (vegetarian capsule shell), magnesium stearate (vegetable grade).

Who It's For

AlgaeCal Plus is generally used by adults who are:

• Looking to support bone density as part of a long-term routine, particularly past their 40s and 50s

• Managing lower bone density and want a calcium source that isn't rock-derived

• Sensitive to traditional calcium carbonate/citrate supplements

• Following a vegetarian diet (note: it is vegetarian, not vegan, since the D3 is derived from lanolin)

How to Take It

The standard routine is 2 capsules with breakfast and 2 capsules with dinner (4 capsules total per day), taken with food for better absorption. One bottle typically covers a full month at this dosage.

Frequently Asked Questions

What is inside AlgaeCal Plus? 

Each daily dose provides 720 mg of algae-sourced calcium, 1,600 IU vitamin D3, 100 mcg vitamin K2 (MK-7), 350 mg magnesium, 3 mg boron, 50 mg vitamin C, and 13 trace minerals occurring naturally in the red algae.

Does AlgaeCal Plus cause side effects?

 Most users tolerate it well. A small number report mild digestive discomfort — bloating or an upset stomach — usually when starting out or taking it without food. Because the calcium is algae-derived, it also carries trace iodine, which is worth noting if you have a thyroid condition. As with any supplement, check with a healthcare provider before starting, especially if you're on medication.

Is AlgaeCal Plus better than regular calcium supplements?

 It's a different approach rather than a strict upgrade. Traditional calcium (carbonate or citrate) is rock-derived and typically used at 1,200 mg or more per day. AlgaeCal Plus uses a food-based source at a lower daily dose (720 mg) paired with D3, K2, and magnesium — nutrients that help direct calcium into bone rather than soft tissue.

Is AlgaeCal Plus vegan? 

No. It's vegetarian. The calcium and trace minerals come from plant-based algae, but the vitamin D3 is sourced from lanolin, an animal by-product.

How is AlgaeCal Plus different from AlgaeCal? 

AlgaeCal Plus adds vitamin K2 and a higher magnesium dose on top of the base algae calcium, D3, and trace minerals found in standard AlgaeCal — making it the version generally used for bone density support rather than general maintenance.
