When two or more bones are joined together in the body, this forms a joint. These joints can be rigid, such as the joints that exist between the bones in your skull, or there are mobile joints that help you to move better (knees, elbows, hips). These joints have cartilage on the very ends of the bones at the spot where they join. If you have healthy amounts of cartilage there, everything moves easily. This also protects the bones.

As you age, your joints can begin to suffer. You may not feel like you can run, walk or be as active as you once used to. Maintaining a healthy level of physical activity, eating a healthy diet and getting enough sleep can help you maintain good joint health, but supplements are something that many people use as well.

Choosing a joint health supplement is a lot more convenient than trying to piece together different ingredients that will benefit your joints and collagen production. In this article, I’m going to discuss Primal Flex. This is a supplement made by Primal Harvest that is designed for people with joint issues. I’ll also look at some of the competition, so you have plenty of options to take into consideration.

Claimed Benefits

claimed benefits of primal flex joint health

Primal Harvest states that their Primal Flex product will support healthy joint function, mobility and an overall state of wellness. The ingredients in the product are chosen to decrease inflammation, boost collagen production, increase absorption and much more. Let’s take a closer look at their claimed benefits.

Supports Inflammatory Responses

High doses of turmeric in each bottle of Primal Flex will support healthy movement of your joints thanks to turmeric’s ability to function as an anti-inflammatory. You’ll be able to maintain a much more active lifestyle than you’ve been used to once you get rid of some of that inflammation that’s present in your joints. Other botanical ingredients included in Primal Flex also help to reduce inflammation further.

Joint Health Support

A multi collagen blend in Primal Flex contains type I collagen from an eggshell membrane source, and type II collagen from BioCell chicken collagen. These ingredients help you move better for longer periods of time and help to keep your joints healthy. These are very natural sources of collagen, which many people prefer in a supplement.

Supports Collagen Production

When the body can naturally produce more collagen and maintain healthy levels of collagen in the body and joints, this results in less pain, faster recovery time and more mobility. Primal Flex uses two different types of collagen to help your body repair its joints, but also to increase the body’s own natural ability to produce collagen. Proper levels of collagen in the body act as lubrication for your joints so you feel a wider range of movement without any pain.

Provides Essential Vitamins and Minerals

Primal Flex contains targeted nutritional support from a variety of vitamins and minerals that benefit joint health. This includes a high quality vitamin C supplement as well as magnesium. Magnesium can help with those stiff and immobile joints that are causing you difficulty. Restoring that flexibility with the use of magnesium can be a game changer.

Key Ingredients: How Does It Help With Joint Health?

key ingredients of primal flex joint health

This holistic-based joint health supplement is made up of ingredients that combine ancient methods of healing with some of the latest scientific knowledge regarding joint health that we have available to us. Let’s look at some of the ingredients in Primal Flex more closely.

Turmeric Curcuma Root Extract

Turmeric root is also known as curcumin, and it functions in Primal Flex as a bioprotectant that helps with joint support. It also has very potent antioxidant properties that boost your immune system and decrease inflammation.

Biocell Hydrolyzed Type II Collagen

The Biocell hydrolyzed type II collagen that is in Primal Flex joint health supplement actually exists naturally in the cartilage of our body. When you supplement with additional type II collagen, this can reduce swelling, promote better lubrication in the joints and alleviate any stiffness that you may have.

Ayurveda-Inspired Joint Health Formula

Ancient ingredients like boswellia, turmeric and ashwagandha help to support your joints from the inside out. It is formulated in a way that increases absorption in the body by up to 2000 percent, thanks to ten milligrams of BioPerine black pepper extract.

Eggshell Membrane Type 1 Collagen

Inside of eggshell membranes are protein fibers that are very high in essential amino acids such as valine, cystine, praline and arginine. This type I collagen extract is in Primal Flex to promote more comfortable movement.

Safety and Side Effects

Some of the ingredients in Primal Flex can cause side effects that you may not find comfortable. For example, the turmeric in the product can lead to an upset stomach or diarrhea. Boswellia Serrata has the potential to cause stomach upset, as well as headaches, heartburn and nausea.

If you suffer from other medically diagnosed health conditions such as autoimmune disorders, bleeding problems, liver disease or thyroid disease, you’ll want to consult with your doctor prior to starting Primal Flex or any other joint health supplement. Many of these ingredients in these products can cause adverse effects for people with these health issues.

1st Phorm Collagen with Dermaval

Since collagen is located in each of our joints, it makes sense to focus in on this part of the body. You can keep your joints healthy with the use of 1st Phorm Collagen with Dermaval. It also helps to keep your skin, hair and nails healthy. Five different collagen sources provide a very vast amino acid profile. There are also 50 milligrams of Dermaval in this product. This is a phytonutrient that promotes healthy levels of elastin in the body, which is also in your joints. Elastin levels can be low in people dealing with arthritis. When you can increase your elastin, this can ease your symptoms while also helping to decrease inflammation.

Primal Turmeric Complex

Primal Harvest also has a Primal Turmeric Complex supplement as part of their brand lineup that is designed to support a healthy brain, heart as well as digestive system. It promotes a healthy inflammatory response to improve comfort in your joints thanks to 400 milligrams of potent turmeric in each dose of Primal Turmeric.

Final Thoughts: Is It Effective for Joint Health?

primal flex effective joint health supplement

I would say that Primal Flex by Primal Harvest is a practical supplement that is beneficial for anyone that’s dealing with ongoing joint pain / swelling. Regardless of whether the issue is caused simply by age or because of an injury, all of these ingredients will decrease inflammation and improve joint mobility. The collagen and antioxidants included in Primal Flex will repair any damage that’s present, whether you’re aware of its existence or not. Increased lubrication of your joints will ease the stiffness that you’re experiencing. This is a powerful supplement that I think is worth the expense if you’ve been searching for a way to live a more active lifestyle.

While there is the chance that you may experience some side effects from the regular use of Primal Flex, the risk isn’t very serious. You should notice the issue quite quickly, and you can discontinue use of the product until you’re able to speak with your doctor about what’s going on. Again, you’ll need to check with your doctor prior to starting Primal Flex if you’re dealing with a chronic health condition or are taking a daily prescription medication for a health issue.

Tips for Success from the RD

While Primal Flex and other joint health supplements strive to improve the pain and swelling that you’re experiencing by way of potent and powerful ingredients, there are some lifestyle changes that you can make to make an impact on how you feel. Here are some of my tips:

  • Maintaining a healthy weight is optimal. If you’re in the obese range, this can put additional pressure on your joints that will result in increased inflammation and pain.
  • Exercising regularly can keep your joints loose and healthy. Aim for low-impact activities that strengthen your joints and muscles rather than harm them.
  • A healthy diet that supports joint health should be one that incorporates a lot of anti-inflammatory foods. This includes fruits, vegetables, whole grains, lean meats, fish and healthy oils.
  • Pay close attention to your posture when you’re sitting, standing or moving. If you’re maintaining poor posture, this can put strain on your joints.
