Ingredients (1,735 milligrams per serving)

UC-II® Undenatured Type II Collagen (20 milligrams per serving)

Collagen is the main protein in the various connective tissues in animals, and type II collagen is a type of collagen that makes up your joint cartilage.

“Undenatured” is often a meaningless marketing buzzword, but in this case, it’s a vitally important component of Fortify because it means the collagen is in its more natural form (and not heavily altered by chemicals or heat).

This is important because research shows that denatured collagen has no beneficial effects on joint inflammation.[1]

Studies show that undenatured collagen, however, is highly effective for regulating the immune response that inflames joints and destroys cartilage and bone.[2]

And the best part about undenatured type II collagen is these effects have been demonstrated in both people with arthritic conditions and healthy joints.[3]

That is, whether you currently have joint problems or not, you can benefit from supplementing with undenatured type II collagen.

The clinically effective dose of undenatured type II collagen is between 10 and 40 milligrams.

Raw chicken breast

Meriva® Curcumin (500 milligrams per serving)

Curcumin is the orange pigment found in the turmeric plant, which is the main spice in curry.

It has been used therapeutically in Ayurvedic medicine for thousands of years, and its health benefits are extensive.

For instance, scientists around the world are investigating its effects on a variety of diseases, including cancer, cardiovascular disease, osteoporosis, diabetes, Alzheimer’s, and more.[4]

Curcumin inhibits a pro-inflammatory enzyme known as cyclooxygenase (COX), and that’s why research shows it reduces inflammation in the joints, relieves pain and stiffness, and improves mobility.[5][6]

The clinically effective dose of Meriva® curcumin is 500 milligrams.

We chose Meriva® for Fortify over curcumin with black pepper extract (a common pairing) because the latter may influence the absorption and metabolism of other substances, including drugs, whereas Meriva has no such potentially adverse interactions.


AprèsFlex® Boswellia Serrata (125 milligrams per serving)

Boswellia serrata is a plant native to much of India and Pakistan that produces an aromatic substance known as frankincense, which has been used for thousands of years in Ayurvedic medicine to treat various disorders related to inflammation.[7]

Frankincense contains molecules known as boswellic acids, including one in particular known as acetyl-11-keto-β-boswellic acid (or AKBA), and research shows they inhibit the production of several proteins that cause inflammation in the body.[8]

This effect extends to the joints, which is why studies show that Boswellia serrata reduces joint inflammation and pain, as well as inhibits an autoimmune response that eats away at joint cartilage and eventually causes arthritis.[9]

The clinically effective dose of Boswellia serrata is between 100 and 200 milligrams, depending on its boswellic acid content.

Boswellia Serrata plant

Grape Seed Extract (90 milligrams per serving)

Grape seed extract is a substance derived from the ground-up seeds of red wine grapes that has long been used in European medicine.

It contains a powerful antioxidant known as procyanidin B2, which remains in the body for much longer than other similar molecules and improves blood flow to the joints.[10]

That's why research shows that grape seed extract helps protect joints from damage caused by an autoimmune response that eats away at them, eventually causing arthritis.[11][12]

Studies also show that supplementation with grape seed extract provides other benefits, including . . .

  • Protecting eye health[13]
  • Reducing risk of heart disease[14][15]
  • Improving blood glucose control[16]
  • Enhancing blood flow to the extremities, which can reduce the appearance of varicose veins[17]
  • Potential anti-cancer activities[18][19][20]

The clinically effective dose of grape seed extract is between 75 and 300 milligrams.

Grapes and grape seeds

Agmatine Sulfate (500 milligrams per serving)

Agmatine is a neurotransmitter created in the body from the amino acid L-arginine (and sulfate is a substance used to simply stabilize the agmatine).

Agmatine enhances the function of the body’s opioid and cannabinoid systems, which are intimately associated with relieving pain and producing feelings of pleasure.

That’s why research shows that supplementation with agmatine sulfate may relieve pain (including joint pain) caused by nerve irritation or damage.[21]

The clinically effective dose of agmatine isn’t established yet, but research suggests a wide range of efficacy, from hundreds of milligrams to several grams.

Whole egg and broken in half egg with yolk inside

Vitamin C (500 milligrams per serving)

Vitamin C is an antioxidant that helps maintain healthy tissues, teeth, and gums, promote wound healing, and boost immune function.

Studies show that vitamin C is effective at decreasing the risk of developing and treating Complex Regional Pain Syndrome (CRPS), which is a difficult-to-diagnose form of chronic pain that typically develops after an injury.[22]

Additionally, as vitamin C plays a role in the synthesis of joint collagen, it’s theorized that supplementation may enhance this process, but more research is required.

The clinically effective dose of vitamin C for potentially impacting collagen synthesis and preventing and treating CRPS is 500 milligrams per day.

No Artificial Food Dyes or Other Chemical Junk

Studies show that artificial food dyes may cause negative effects in some people, including gastrointestinal toxicity and behavioral disorders.[23][24][25][26][27]
