What healthcare professionals say
What happens to our tendons after 50?

Low Collagen Production
Low estrogen in women aged 50–75+ disrupts collagen production — the protein that gives your tendons strength and elasticity.

Tendons Start To Degenerate
Low collagen production causes tendons to become weaker and stiffer over time. The tell-tale sign is a deep, radiating ache in the hips and knees.

Tendinopathy VS Arthritis
Arthritis is an inflammatory condition that can be managed with over-the-counter (OTC) meds or cortisone shots. Tendinopathy requires more than that — it needs a holistic collagen-building approach to ensure lasting relief.
Traditional Joint Care Isn't Enough...

01
Masks the pain. Doesn't stop the degeneration.
Over-the-counter (OTC) meds and cortisone shots only mask the pain by addressing surface-level flareups. They do NOT stop tendons from degenerating.

02
Repeated cortisone shots can backfire.
Repeated cortisone shots can lead to further tendon weakening and even ruptures.

03
OTC meds aren't safe for long-term use.
OTC meds may not be safe for long-term use. Kidney stress, GI ulcers, cardiovascular issues are just some of the many side-effects women have brought up.
How does Osteva™ work?
Unlike traditional joint-care methods that just mask symptoms, Osteva targets the root cause of discomfort by replenishing the structural proteins and nutrients your tendons need to be healthy — in your 50s and beyond.
Clinically-studied ingredients that are gentle on the stomach & safe to take long-term

Tendaxion® (Hydrolyzed Type I Collagen + Mucopolysaccharides)1
- Feeds your tendons critical building blocks for healthy collagen fibers
- Clinical trials show Tendaxion® may reduce hip and knee discomfort after 12 weeks of intake
- Climb stairs without that sharp, pulling ache in the hip flexors and outer thigh

Collavant® n2 (Native Type II Collagen)2
- Helps preserve the structural integrity of joint cartilage by preventing the release of collagen-degrading enzymes
- Studies show Collavant® supports recovery and joint function as early as 6 weeks
- Spring out of bed every morning with youthful vigor

Vitamin C (Ascorbic Acid)3
- Stimulates new collagen production and stabilizes tendon structure by reducing oxidative damage
- Studies show taking vitamin C may support tendon recovery when combined with collagen & rehab protocols
- Minor tendon strains may take a shorter time to dissipate

Boswellia Serrata Extract (Indian Frankincense)4
- Blocks 5-LOX enzymes — one of the chemicals responsible for cartilage breakdown
- Studies suggest Boswellia may help soothe occasional knee discomfort within weeks
- Walk longer distances without throbbing, nagging knee aches

Curcuma Longa (Turmeric Root Extract)5
- Possesses analgesic properties that may inhibit pain signals for natural relief from hip and knee aches
- Studies suggest curcumin also supports a healthy inflammatory response for fewer flareups
- Finally sleep on your side again with minimal discomfort

Copper (as Copper Citrate)6
- Helps "fuse" new collagen fibers together so tendon & cartilage structures are reinforced
- Studies have linked higher copper levels with lower instances of tendinopathy and healthy connective tissue integrity
- Enjoy more support and 'spring' in each step — especially on uneven ground or when changing directions

Manganese (as Manganese Chelate)7
- Supports production of proteoglycans — the spongy layer in cartilage that cushions joints during impact
- Studies suggest manganese enhances collagen cross-linking when paired with Vitamin C and copper
- Move more fluidly — whether you're gardening, dancing, or simply standing up from a low chair

"Osteva to the rescue! I have been able to reduce my pain meds which is a win. Very pleased to finally get natural relief for my aches and pain."
Julie E.
"I have been taking Osteva for about 3 weeks now. I love this product. During the first week I didn't notice much of a change. By the end of the second week, I realized that the pain I always had in my hip and my knees was now just a dull ache. During the third week, my hip and knee discomfort was completely gone! I only feel a twinge every now and then. I will definitely make Osteva part of my daily supplement routine!"
Lisa W.
"I'm 16 days into taking Osteva, and I'm really beginning to feel a change! My knees barely hurt at all. It happened suddenly on day 14... I didn't believe it at first, but two days later and still no aches! Amazing!"

Sore elbow and knees need this
My sore knee and achy elbow joints have really benefitted from using this Rejuveen Osteva product.
Fantastic
I didn't think it was possible to bring down the swelling and the pain in my knee, but Rejuveen has really had this effect. I have shared it with so many people because it is truly great!!
A winner!
I was skeptical at first but after two weeks I can tell a huge difference.
Hip pain was substantially reduced
I was experiencing very painful hips that were getting worse over time. As a professional rider, I was concerned that my career was over. I tried Osteva and within 2 months my pain was gone. Attributing this pain to hormonal changes, Osteva has been a game changer for me.
Made my life pain free!!
I am 59 and have been in menopause for almost 20 years. I managed the symptoms through HRT and supplements. About two years ago I started having really bad hip pain that got really bad after a motorcycle trip with a friend. I saw this online and started taking it and within one week my hip pain was gone! I can do whatever I want — sit for long periods, ride a motorcycle, etc. We'll never stop taking it!
