Is Calcium & Magnesium Algae Marine Complex right for you?

An honest guide to help you decide.

A great fit if you...

  • want comprehensive everyday support for bones, joints and teeth
  • want calcium and magnesium from a natural, plant-based source
  • want D3, K2 and boron alongside your essential bone-building minerals
  • prefer calcium and magnesium in a balanced 2:1 ratio
  • want additional support for normal muscle function
  • are looking for a comprehensive long-term bone health formula

Seek advice or consider another option if...

  • you take warfarin or other vitamin K-antagonist medication
  • you have a condition affecting your kidneys or calcium levels
  • you have been advised to restrict your calcium or vitamin D intake
  • you require a higher-dose, targeted calcium supplement
  • you already take significant amounts of calcium, magnesium, D3 or K2
  • you're unsure whether it is suitable alongside your medication or supplements

How Calcium & Magnesium Algae Marine Complex compares

Not all are formulated the same. See how ours compares.
Calcium & Magnesium Algae Marine Complex Typical
Calcium source Plant-based Aquamin® marine algae Often mined
Calcium & magnesium Balanced 2:1 ratio Ratios vary
Supporting nutrients Vitamins D3, K2 MK-7 + boron Often calcium & magnesium only
Vitamin K2 120µg all-trans MK-7 No
Trace minerals Naturally occurring mineral matrix No
Daily serving 2 tablets Varies

What to expect

Magnesium and L-theanine build steadily — here's a realistic timeline of how your family may notice the difference.
1
What you may notice
Calcium and magnesium support normal muscle function, while magnesium also contributes to normal energy metabolism and the reduction of tiredness and fatigue. Some benefits may therefore be more noticeable than others.
2
With consistent use
Bone health is a long-term investment, not something you'll likely feel changing. Consistent daily use provides calcium, magnesium, vitamin D3, K2 and boron to complement a bone-supportive diet and lifestyle.
3
Good to know
The benefits to your bones happen in the background, so you shouldn't expect to feel an obvious change. Think of this as long-term nutritional support, helping maintain normal bones and teeth with consistent daily use.

FAQs

What is Aquamin®?

Aquamin® is a range of naturally derived marine mineral ingredients. In our formula, Aquamin® calcium is sourced from calcified red marine algae (Lithothamnion species), while Aquamin® magnesium is derived from seawater. Together, they provide calcium and magnesium alongside naturally occurring trace minerals from their respective marine sources.

Why combine calcium and magnesium?

Calcium and magnesium both contribute to the maintenance of normal bones and teeth and support normal muscle function. Rather than focusing on calcium alone, our formula provides 443mg calcium alongside 223mg magnesium - a balanced ratio of approximately 2:1.

Why does the formula contain vitamins D3 and K2?

Bone health involves much more than calcium alone. Vitamin D supports the normal absorption and utilization of calcium and helps maintain normal blood calcium levels, while vitamin K contributes to the maintenance of normal bones.

Each daily serving provides 20µg (800iu) vitamin D3 and 120µg vitamin K2 as all-trans MK-7, alongside calcium, magnesium and boron for comprehensive everyday bone support.

Why is boron included?

Boron is a naturally occurring trace mineral found in foods such as fruits, vegetables, nuts and legumes. It has an established relationship with mineral metabolism and is included as part of our comprehensive approach to bone nutrition. Each daily serving provides 3mg boron.

Is the calcium in this product plant-based?

Yes. Aquamin® calcium is derived from calcified red marine algae rather than traditional mined calcium sources. The algae naturally absorb minerals from the surrounding seawater as they grow, creating a mineral-rich structure that contains calcium and naturally occurring trace minerals.
