Skeptical? Good. So are we.

If you've been let down by bold claims from supplement companies before, we understand. We have too. That's why we do things differently.

We didn't just say our calcium supplement increases bone density. We backed it. With not one, not two, but three human clinical studies. These independent studies were published in peer-reviewed scientific journals. And the results have been confirmed by thousands of DEXA scans in medical clinics across all 50 states.

So if you're skeptical, we welcome it. Read the studies. Check the ingredients. Head to YouTube and search “AlgaeCal reviews.” Because when something actually works, it doesn't mind being held to a higher standard.

The numbers don't lie.

And the results speak for themselves.

Clinically Supported

AlgaeCal has been studied in three human clinical trials conducted by researchers from leading institutions including Harvard Medical School, Georgetown University, and the University of Texas. The conclusion was the same across all three:

AlgaeCal is the only calcium supplement ever shown to increase bone density‡.

Plant-Based Calcium

Most Natural Calcium Supplements are Made From Rocks

AlgaeCal is different. It's made from organic marine algae — mesophyllum superpositum - a plant-based source that naturally contains all the bone-supporting minerals your body needs to stop bone loss and increase bone density.

All the Nutrients You Need

AlgaeCal Plus contains 16 bone-supporting nutrients – including our organic ocean calcium, boron, magnesium, vitamin C, vitamin D3, and vitamin K2-7. This unique formulation was the first – and still only – calcium clinically supported to increase bone density.

Make Skin Look Younger

Collagen, making up 75% of your skin, is key to a youthful look, providing firmness and radiance. However, as we age, collagen levels drop, leading to wrinkles, saggy skin, and dullness. AlgaeCal Collagen addresses this with VERISOL®, a clinically proven collagen shown in studies to enhance skin elasticity by 10% in just 28 days and reduce eye wrinkles by 32% in 2 months. Essentially, it rejuvenates your skin at the cellular level, enhancing firmness and glow for a visibly younger appearance.1,2

Thicker Hair & Stronger Nails

In the VERISOL® collagen studies, participants saw nail growth speed up by 12%. Even more impressive, participants experienced a 42% decrease in nail breakage. Plus, their hair got thicker, with a 31% increase in follicle strength in just 4 months! In other words, their hair and nails not only grew faster, but appeared stronger and more youthful.3,4

Cushioning For Joints

In a study at Tufts Medical Center, FORTIGEL® showed measurable improvements in cartilage composition in load-bearing areas of the knee. Using a specialized MRI technique, researchers detected significant increases in a marker of the proteoglycan matrix. That’s the part of healthy cartilage that absorbs shock and cushions your joints every time you move.5

Knees Feel 10 Years Younger

Over time, people tend to lose flexibility in their knees – about 1 degree per decade on average. But, a 2022 study found that UC-II® collagen can significantly change that. In the study, adults aged 20-55 with joint discomfort took either this collagen supplement or a placebo for 24 weeks…

The collagen group saw a dramatic improvement. And their knees felt as if they had regained a decade's worth of flexibility. Supported by over 20 years of clinical research, including 11 human trials, UC-II® is the only collagen clinically supported to enhance joint flexibility.6

Increase Bone Density

FORTIBONE® special peptides signal the bone-forming cells to boost collagen synthesis, which is crucial for strong and healthy bones. It also helps slow down the breakdown of bone tissue, leading to an overall increase in bone strength. In a study from 2021 FORTIBONE® was found to significantly boost bone strength in postmenopausal women over four years. One group saw their bone density increase by 5.79% in the spine and 4.21% in the hip area.7
