The idea that joint pain is treatable using natural medicines is not new either. Look, I have a 6,000 year old natural remedy available called, hemp, which is now more available and more bioavailable than ever before.
A peer-reviewed article that appeared in the Journal of Surgical Neurology International addresses that question, which natural substances are anti-inflammatory agents for pain relief. 
It also brings up the increasing popularity of using natural curative over prescription drugs because of the fewer side effects associated with natural products. The journal article from Surgical Neurology International looks at the use of natural products such as Omega-3 Fatty Acids, White Willow bark, Curcumin, Green Tea, and other natural substances that have a long history of treating inflammation and joint pain. 
It was not so long ago in our history that fish oil was an everyday product that mother's reached for as a tool to treat joint pain. You might even remember Cod Liver Oil as a child. An issue with some natural products back in the day was that the products expired or went bad.
One did not just buy a serving of it. No. It came in a large brown bottle and was administered a tablespoon at a time. Not so bad if you received the first or second does, but from there on, the rancid taste might well have been worse than the joint pain.
Technology is not only advancing what we can do but reopening doors to past treatments that might well be the best thing in medicine today.
There are many peer-reviewed studies that point to the positive effects that omega 3 fatty acids have on pain and inflammation.
A peer-reviewed study from 2013 that appeared in the AAPS Journal discusses the benefits of Curcumin and Turmeric.
The study goes on to discuss how curcumin helps control nerve signals. It is the modulation or the controlling of nerve signals that are the power behind what curcumin can do. Hard to get enough into the body systemically to realize benefits for the most part.
Curcumin is a molecule or substance found in turmeric. As a potential drug, curcumin place in medical studies dates back at least a century. It has since been studied as a potential aid to certain types of cancer and as an anti-inflammatory agent. 
Two key proteins that lead to inflammation are homocysteine and C-reactive. Homocysteine is an indicator of heart disease, and it is often present in elevated volumes when diseases that involve inflammation occur.
There are studies that show that vitamin B6, folate (B9) and B12 help our body to lower the levels of both homocysteine and C-reactive proteins. 
Quality, healthy supplements that focus on Vitamin B6, Folate, and B12 are a perfect way to add more vitamin B to your diet. Hard to get enough into the body systemically to realize benefits for the most part.
Vitamin C has a long history as an immune booster. There are plenty of studies that high doses of vitamin C help fight advanced diseases such as cancer.
The role that vitamin C plays in our body is complex. It is an antioxidant which helps to reduce the stress that cells undergo as they utilize nutrients for fuel.
Healthy cells are a baseline goal as the healthier our cells are, the healthier we are.
Since inflammation is a natural response to infection and injury, vitamin C helps our body by boosting immune response before we become sick.
If you want to add more vitamin C to your diet, consider taking supplements 2-3 times per day. Vitamin C is absorbed quickly by our body and excreted quickly too. To maintain a viable level throughout the day, add vitamin C to your breakfast, lunch, and dinner routines. You can also add quality foods such as ripe citrus and brightly colored vegetables such as peppers, squash, and tomatoes.
Vitamin D deficiency has a correlation to inflammatory disease. Several studies looked at the effects of vitamin D deficiencies in larger populations and the resulting presence of inflammatory disease.
The results are somewhat murky as the medical-science community argues over what is an appropriate dose of vitamin D. The current standards push the required dosage of vitamin D so high that it would be impossible to satisfy that need without the use of vitamin D supplements.
Currently the best source of Vitamin D is through the use of supplements.
However, you find vitamin D in foods such as milk, oily fish, salmon, egg yolks, and even in beef liver. 
One reason for the higher doses is that evidence shows that bacterial infections have the means of reducing or eliminating the role that vitamin D plays as an immune system supporter. The result is inflammation. What is important is that your body has sufficient levels of vitamin D.
Vitamin E is an antioxidant that plays a part in keeping inflammation at bay. As an antioxidant, vitamin E helps reduce the effects of oxidation (cell damage) helping in keeping our cells at optimum health.
In a study that looked at the effects of colitis in rats had an outcome that shows how powerful vitamin E is, as an anti-inflammatory agent.  Hard to get enough into the body systemically to realize benefits for the most part.
For many decades medical studies focused on vitamin K, but recently the focus shifted as technology made the role of vitamin K clearer.
For anti-inflammatory benefits, it is not specifically vitamin K but vitamin K2 that holds promise. There are peer-review studies that show how vitamin K2 reduces inflammation  in rheumatoid arthritis.
Adding more vitamin K2 to your diet is a bit tricky as many food labels do not list vitamin K. The best source is via a quality supplement, but you can also find vitamin K (not specifically K2) in foods such as:
Spinach and leafy greens
Brassicas such as Brussels sprouts, broccoli, kale and cabbage
Fermented foods such as Natto, kefir, and yogurt
Prunes, plums, and other stone fruits
The National Institutes of Health recommends that 75 mcg of vitamin K per day for people aged 14-18 and 120 mcg for men over the age of 19, and 90 mcg for women over the age of 19.  Hard to get enough into the body systemically to realize benefits for the most part.
Inspired by the miraculous ability of our body to regenerate and heal itself when in homeostasis, we have found a way through advances in technology to enhance the modern resurgence of natural care and eliminate pain quickly while enhancing overall health of the body utilizing pure botanical extracts with extremely high bioavailability. This allows more of the natural compounds to actually enter the body systemically and provide very fast anti inflammatory responses. Since this product is natural and organic, there are not contraindications and therefore safe for all ages.
The important part of any type of supplement is, how much of the supplement that you are paying for actually gets to go to work inside the body. Most supplements go through the digestive system which weakens the benefit by close to 80%.
Options like Zro+ actually get into the body systemically very quickly which increases the efficacy considerably.
The lessons that we learn from these studies is that our body uses natural substances to help control inflammation and pain.
One of the easiest things you can do is to simply eat a better diet so that you can add natural supplements for joint pain and inflammation to your daily routine.
Eat Well - Eating well is a matter of making some positive choices such as going organic, eating whole foods, making sure to drink plenty of quality water, and of course eating more vegetables. Is your diet doing all it can for your health?
Give up Your Vices - Live a life of balance. While that is often easier said than done, you can make positive gains by giving up smoking, not drinking excessively, and make sure that everything you do is balanced and equal:
One problem with modern lifestyles is that we tend to do only a few things. Maybe we jog every day or watch TV for three hours every evening.
Change up your routine and get off the couch. Go for a walk rather than just running.
Walk to the park and read your book rather than watching TV. Build quality family time rather than just being sloth-like.
What we learn from these studies is that many of the answers to better health and pain-free living do not have to involve prescription drugs. As individuals, we have a lot of choice in what we eat, what we do, and how we live. Can you make lifestyle changes that not only improve your health today but in the long-term too? You can.....
