Fix the Cause. Feel the Relief. Stay in the Game.
Tissue Rejuvenator is not just another quick fix — it’s a powerful two-part formula designed to repair and restore joints, tendons, and soft tissue, while also reducing swelling and easing pain fast.
Unlike typical painkillers that simply mask the problem, Tissue Rejuvenator works on two levels:
- Immediate relief to help you move comfortably again
- Long-term support to rebuild and strengthen damaged tissue
Whether you’re dealing with a recent knock, a stubborn niggle, or ongoing wear and tear, this formula is built to handle both acute injuries and chronic conditions.
It’s also a smarter alternative to NSAIDs — offering effective relief without relying on harsh medication, while improving results the longer you use it.

FAQS
Do the ingredients in Tissue Rejuvenator come from shellfish?
Yes — the glucosamine sulphate used in most joint supplements, including Tissue Rejuvenator, is typically derived from shellfish.
However, it comes from the shells, while allergens are found in the flesh, so it may be suitable for some people with shellfish allergies. That said, we strongly recommend consulting your doctor before use if you have an allergy.
For those avoiding animal products, we also offer a Vegan Tissue Rejuvenator, which contains no shellfish or animal-derived ingredients.
Are your supplements third-party tested?
Yes. Every Hammer Nutrition supplement is independently tested to meet strict FDA standards.
We test for:
- purity
- strength
- identity
- overall quality
This testing takes place at every stage, from raw ingredients through to the finished product — so you can trust what you’re taking.
What does “MFG” (Manufacture Date) mean?
“MFG” shows when the product was made.
Our supplements remain fresh and effective for up to 4 years from this date, as long as they are stored away from heat and direct sunlight.
What helps with bone healing and long-term bone strength?
If you’re recovering from a fracture or looking to support bone health long term, these supplements can make a real difference:
Premium Insurance Caps
A broad-spectrum formula providing key nutrients like vitamin C, D, B6, magnesium, calcium, zinc, and selenium to support overall and bone health.
Suggested use: 2 capsules, 2–3 times daily
Essential Mg (Magnesium)

EnDuro D (Vitamin D3 + K2)
Supports calcium absorption and bone density, while helping direct calcium into bones (not arteries).
Suggested use: 1 daily (2 daily for repair)
Tissue Rejuvenator
Supports connective tissue around bones, helping reduce soreness, swelling, and stiffness.
Suggested use: 2 capsules twice daily
LSA Caps (Selenium support)
Helps protect bone health through its antioxidant role, supporting bone density and reducing risk factors linked to osteoporosis.
Suggested use: alongside Premium Insurance Caps for optimal intake

IMPORTANT NOTE FOR THOSE WITH SHELLFISH ALLERGIES
Glucosamine sulfate is usually derived from shellfish; the overwhelming number of joint health supplements containing glucosamine - including Tissue Rejuvenator - use shellfish-derived glucosamine sulfate. However, since glucosamine is derived from the shells of these animals, while the allergen is within the flesh of the animals, it may be safe (key word "may") to use Tissue Rejuvenator even for those with a shellfish allergy.
Still, using the adage "when in doubt, don't," we adamantly recommend that anyone with a shellfish allergy consult their physician before taking Tissue Rejuvenator or any glucosamine sulfate-containing supplements.

Helped on a climb in 34c heat…. Yum flavour too
I've been using these for years and feel they give me a good foundation for my health.
Easy to take and and did the job. Meant I could drink plain water without missing out on electrolytes
My go to product to supplement my electrolyte needs.
Easy to use and nice taste.
On Saturday 14th September I stood on the start line at Bewts Y Coed. This was my 3rd 100 miler this year.
I have used Hammer since around 2010 in my Ironman days. As of today I have completed 428 marathons ‘all official races’ around the globe.. also quite a few ultras in my time.
I have used Recoverite on multi day ultras for the last 10 years. Great mix and flavour. I have converted many to this product.
Seems to be really helping recovery from my knee strain. I had a similar issue a couple of years ago which took weeks to sort. Fair do’s it doing what it says it will.
Tasty and light on the stomach.
I will definitely order many more of these
Great electrolytes and gentle on the stomach.
I have a sensitive stomach but these products are the best I have tried.
Another superb product from the Hammer Team. Dissolves so quickly with just a stir with a spoon or a quick shake in a bottle. Can feel the difference in sleep pattern for sure and energy levels have been more consistent with the mid afternoon lag not being as noticeable.
