Your Stronger Bones For Life Guarantee
We guarantee that AlgaeCal's Bone Builder Pack will increase your bone mineral density or your money back. The 16 bone-supporting nutrients start to work from the very first day you begin to take them. And you're guaranteed to see measurable results on a DEXA scan after just six months.
This guarantee doesn't only cover you for the first six months. It covers you for life. That's right. We promise that your bone density will continue to increase, with every DEXA scan showing better results than the last...for your lifetime.
And if any scan result fails to show progress, we'll refund every penny you've paid for all products purchased since your last scan. Leaving you with no risk - either your bones get stronger, or you get ALL your money back.
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‡.
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.
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.
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.
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.

Frequently Asked Questions
AlgaeCal Collagen delivers a unique blend of four clinically supported collagen peptides:
VERISOL®: Type I & III collagen shown to reduce wrinkles and improve skin elasticity.
FORTIGEL®: Type II collagen that supports joint cartilage and mobility.
UC-II®: Undenatured Type II collagen that helps maintain healthy joint function and comfort.
FORTIBONE®: Type I collagen clinically supported to stimulate bone-building cells and improve bone health.
Together, these collagens work from the inside out to support bones, joints, skin, hair, and nails, giving your body the same structural proteins it naturally relies on for strength, structure and flexibility.
Simply mix one scoop of AlgaeCal Collagen into your favorite hot beverage for a full clinical dose of the four collagens. The powder is completely flavorless and odorless, so it won’t change the taste of your drink, and it dissolves easily with no clumping. For best blending, add the powder to your cup before pouring in the liquid. You can also stir a scoop into a smoothie or sprinkle it over meals for the same bone, joint, and skin benefits.
AlgaeCal Collagen itself contains no known allergens. It’s completely free of dairy, gluten, soy, and shellfish. However, it is produced in a facility that also handles products containing common allergens. The facility follows strict Good Manufacturing Practices (GMP) to prevent cross-contamination, but the finished product is not specifically tested for every potential allergen. If you have a severe allergy, we recommend reviewing the ingredient list and consulting your healthcare provider before use.
In clinical studies participants saw visible benefits from VERISOL® in as little as 28 days, with participants noticing improved skin elasticity and smoothness within the first month. Continued use delivers deeper changes—such as stronger hair and nails, reduced appearance of cellulite, and improved joint comfort and mobility—typically within 2 to 6 months. Individual results will vary, but consistent daily use is key to achieving the full spectrum of clinically supported benefits.
Yes! AlgaeCal Collagen is heat-stable, flavorless, and odorless, so you can safely mix it into hot drinks like coffee, tea, or hot chocolate without affecting taste or potency. It dissolves smoothly with no clumping, especially if you add the powder to your cup before pouring in the liquid. Whether it’s part of your morning coffee or an evening herbal tea, you’ll get the full clinical dose of all four collagens in every scoop.
Collagen production naturally begins to decline around age 30, but research shows benefits for younger people as well. In fact, a clinical study of 147 young athletes (average age 20) found that FORTIGEL® collagen helped reduce activity-related joint pain. That said, for children or teenagers, it’s always best to consult a pediatrician or healthcare provider before starting any supplement to ensure it’s appropriate for their age and individual health needs.
Yes. Clinical studies on two of the key collagens in AlgaeCal Collagen show meaningful support for joint comfort.
- In the FORTIGEL® clinical studies, participants experienced less activity-related joint pain than those taking a placebo, which reduced their reliance on over-the-counter pain relievers, ice packs, and physiotherapy.
- UC-II® clinical studies found significant improvements in joint flexibility and comfort during everyday movements such as climbing stairs, bending, and squatting.
Together, these results show that the patented collagens in AlgaeCal Collagen can help reduce joint discomfort and improve mobility when used consistently.
AlgaeCal Collagen combines four patented, clinically supported collagens VERISOL®, FORTIGEL®, UC-II®, and FORTIBONE®. Together these are backed by 25 human clinical trials (18 double-blind, placebo-controlled) to help reduce wrinkles, improve skin elasticity, smooth the appearance of cellulite, and increase hair thickness and shine. It also supports stronger, faster-growing nails, promotes knee cartilage health, enhances joint flexibility and comfort, reduces activity-related knee pain, and even helps improve bone health.
All that from just one scoop in your morning coffee!
AlgaeCal Collagen is made from natural, food-based ingredients, but it’s always best to check with your healthcare provider before starting any new supplement—especially if you have a medical condition, take prescription medications, or are pregnant or nursing. Your doctor can review the ingredients and ensure it’s appropriate for your individual health needs.
Collagen is a naturally occurring protein in the body, and supplementing with it is considered safe for long-term, daily use. In fact, clinical studies on the key collagens in AlgaeCal Collagen have followed participants for up to four years with no safety concerns. As with any supplement, if you have a medical condition or take prescription medications, it’s always a good idea to check with your healthcare provider to make sure long-term use is appropriate for you.
