6:55 Why you need glycine

In this video, we’ll discuss a very important amino acid: glycine. Collagen is a main component of connective tissues, tendons, ligaments, and cartilage. About ⅓ of collagen is made by glycine.

Your body can make glycine, but unfortunately, it doesn’t make very much. If you're not getting it from the diet, you could be deficient. Unless you’re eating the skin and cartilage from meat, you’re probably not getting enough glycine.

Glycine is needed to make the most important antioxidant for all of your cells, glutathione. Without enough glycine to make glutathione, you can’t detoxify your body. This can cause a buildup of toxicity, leading to inflammation.

Glycine is a potent anti-inflammatory agent and is an essential building block for many enzymes and proteins.

Here are some of the many important functions of glycine:
• Makes heme in your blood
• Important for gum health
• Essential for DNA
• Building block for catalase
• Supports sleep
• Supports the liver
• Can help fix a leaky gut
• Detoxifies uric acid
• Supports blood sugar
• Helps with weight loss
• Reduces visceral fat

Glycine can also turn into glucose to be used as fuel. Certain parts of the body, especially the brain, need a certain amount of glucose. If you’re not consuming glucose, your body can make it. Glycine is a precursor for glucose, but don’t worry about it bumping you out of ketosis. Glycine stimulates the hormone glucagon, which opposes insulin.

If you’re not eating animals nose-to-tail, if you’re under stress, taking medication, drinking alcohol, or exposed to toxins, you can become deficient in glycine.

You can increase your glycine intake by consuming gelatin! Try making your own gelatin using Knox Blox and using a natural sweetener like stevia. You can also take a glycine supplement. The average person needs about 4 to 10 grams of glycine per day.

Bone broth and pork rinds can increase your glycine intake, but you need to consume a lot to get enough glycine.

As we age, we need more glycine. Increasing glycine intake can potentially help people with osteoarthritis, osteoporosis, hair thinning, insomnia, gout, and kidney stones.

    Glycine is found in various protein-containing foods, particularly those that are high in collagen or gelatin. Some foods that are good sources of glycine include:

    1. **Bone broth:** Bone broth made from simmering animal bones and connective tissues is rich in glycine.

    2. **Gelatin:** Gelatin, which is derived from collagen, is a concentrated source of glycine. It’s found in foods like Jello, gummy candies, and certain desserts.

    3. **Meat:** Animal meats, such as beef, pork, poultry, and fish, contain glycine, especially in connective tissues and skin.

    4. **Seafood:** Fish and shellfish are good sources of glycine, particularly in the skin, bones, and cartilage.

    5. **Dairy products:** Some dairy products, like milk, cheese, and yogurt, contain glycine, although in smaller amounts compared to meat and gelatin.

    6. **Eggs:** Egg whites contain glycine, along with other amino acids, making eggs a good source of protein.

    7. **Soy products:** Soybeans and soy-based products, such as tofu and tempeh, contain glycine, although they may have lower levels compared to animal-derived sources.

    8. **Legumes and beans:** Certain legumes and beans, such as chickpeas, lentils, and black beans, contain glycine, although the levels may be lower compared to animal-based sources.

    Incorporating a variety of these foods into your diet can help ensure an adequate intake of glycine, along with other essential nutrients. 🤗👌 😉

    • @user-sy7ck3ln6o on March 22, 2024 at 1:21 pm

      yup yup yup! BEEF BONE BROTH IS A MAGICAL DRINK! the amount of glycine in a cup of bone soup can range from 500 mg to 1700 mg (0.5 to 1.7 g) Warm it up and drop a couple of tspoons of butter.. Wow.. so addictive.. you’ll get more than enough “glycine” by drinking a couple of cups of this every day.. and the bonus is Beef Bone Broth is super rich in collagen and about 8 to 9 gram of protein per 1 cup. I personally mix in 2 tsp of Beef Gelatin Powder.. for another 8 grams of protein.. The amino acid composition of gelatin is approximately: 21 percent glycine. 12 percent proline. 12 percent hydroxyproline. Mix the Gelatin Powder in cold, then warm up. Drinking Bone Broth.. makes these valuable amino acids more bio available than any other source!

    I had a herniated disk about 15 years ago. The pain was so intense I would scream in agony as I CRAWLED to the bathroom. The doctor said I would need surgery. After hearing the horror stories from other co-workers who HAD the surgery I decided against it. I had remembered an elderly lady I knew who had hand pain from arthritis who took gelatin (I had read an article about it in the 1990’s and told her about it). She had lived in pain for decades until she took the gelatin. After about 2 or 3 weeks of hydrolyzed Knox gelatin (at the time you could buy a months supply at the grocery store for about $15, but they stopped selling it years ago) the back pain disappeared. As long as I take gelatin daily I have NO pain at almost 70, but if I stop taking it within a few days I feel a nudge to restart it. My back feels like it did when I was 18 as long as I take the gelatin. I purchase 20 pails of it online (now about $170 for hydrolyzed gelatin) that lasts almost a year.
    I still have the DVD with the MRI images of the disk as proof.
