OsteOrganiCAL® Plus
5/5 Our Natural Bone Builder Supplement

Plant-Based Calcium

Highly absorbable calcium, magnesium, and trace minerals from algae

Supercharged bone building supplements

Our signature bone health system combines the properties of plant-based algae calcium and naturally sourced vitamin D3.

OsteOrganiCal Plus consists of highly absorbable organic calcium extracted from algae and natural ingredients like Vitamins D3 and K2, which enhance the body’s ability to absorb calcium into the bones.

Building Bone Density THE NATURAL WAY

What is OsteOrganiCAL® Plus

Whether you find yourself recovering from orthopedic surgery, spinal fusion, hip replacement, and the like, you know the uphill battle you have and how much living these conditions have taken out of your life. Suffering from Osteoporosis or osteopenia causes back pain, as well as knee, hips, and wrist pain.

It is easy for your bones to become very brittle that you may fall due to a broken bone caused by severe Osteoporosis.

With our organic products, many clients have been able to lead a healthier lifestyle by supporting mental and physical wellness in an entirely natural way.

We are continuously seeking ways to improve our products and services while remaining committed to credibility, transparency, and quality.

Now you have all-natural products that will allow you to regain the active lifestyle you love, like playing tennis, golf, skiing, and working out. Orthodontic treatments lead to bone loss and rejection of implants, which can be healed with proper calcium supplementation.

The absorbable source of calcium just mentioned is available in our all-natural, unique, health-based products.

Since our calcium is derived from organic seaweed, it is highly absorbable, and our unique blend creates up to 95% absorption by the body. This will ensure there are no kidney stones or blood clots because any excess is naturally eliminated by urine.

The algae we use comes from a raw source that contributes to its expansion and prolongs its sustainability.

Originally harvested from the waters of Iceland our formulation contains multiple trace minerals that occur naturally and support your body’s uptake of the bioactive calcium as well as contributing to your overall health and vitality.

Scientists in Brazil in the 1990s began researching the natural properties of algae with a particular focus on the marine plant’s rich calcium content.

For those seeking to promote bone strength, these studies proved that algae-based calcium had promising potential as a wellness supplement.

The minerals responsible for the efficient bioavailability of calcium in algae-derived calcium, magnesium, and manganese are available in large amounts.

This led to the discovery that algae-based calcium is absorbed more effectively by the body, which leads directly to bone strength in a completely natural way.

It was based on this science that NATURAL OPTION USA was founded to give people easier access to algae calcium as well as its benefits.

We were on the cutting edge of this technology and one of the first brands to sell this type of sea algae-derived calcium. Our mission has always been to provide people with effective, all-natural wellness products made with high-quality organic ingredients.

What Our Customers Think


Dot H.

I absolutely LOVE Memoral!..I'm almost 78, very healthy and active, but I've noticed I am forgetting lots of little things. Since I've been taking MEMORAL, there's a definite IMPROVEMENT!! Thank you for your product. 

Sandra G.

I had a traumatic brain injury in 2009 and was put on a seizure medication for life! Last year I went to a new neurologist and asked if I could be taken off this medication. She had me take several tests and discovered I still need seizure medication but when she saw what I had been taking all these years she said BUT, we can CHANGE your medication for sure! She said the one I was taking had a terrible side depletes the calcium in a person's body! This was NOT what I needed in my 70's!!! But to my amazement my calcium levels (i.e. bone density)I were almost the same as before and then I told her it was because I was taking Osteorganical all these years!!! I am so grateful to your company and the lady I first spoke with who explained all about the difference in Osteorganical and other calcium supplements. I believe God caused me to understand and say yes. I do remember starting out slowly, but I don't remember the beginning amount nor the rate of increase until I finally have been taking it every day!!! So, thank you, thank you, thank you for this product! I have fallen a few times, but nothing broken at all!!!

Bobbie K.

I have been using the calcium and D-3 supplements for over 15 years. They have increased my bone density in a very significant way, without having to take prescription drugs with all the side effects. More recently, my husband and I have started taking Memoral and we have really noticed the difference it has made in our memories and clarity. This is a wonderful company that cares about it's clients and always goes a step beyond to help their clients. I wholeheartedly recommend this company and it's products.

Phylli P.

I am so glad that I use Osteorganical Plus. I can paint, hang my drapes. I do all my own work, I will be eighty next birthday, these ladies are wonderful women, they will help you. I’ve never been so happy. I walk better, bend down better. So gave it a try, you will love it like I do. I am very happy, and I told all my family about Osteorganical.

Eva C.

After 2 months of using this product I have noticed an improvement on small but important things. I no longer get stuck in the middle of my conversations repeating myself and I also am more aware of where I leave my keys. I did not realize this but my husband made me aware.
