Promotes Healthy Lip Tissue
Benefits and Features
This essential amino acid is required for enzyme production, collagen formation, and tissue repair. Supports the body's natural immune defenses and promotes healthy gum and lip tissue.
Detail Overview
One of the 9 essential amino acids that must be obtained from food, lysine is a key player in enzyme production, collagen formation, and tissue repair. L-Lysine is particularly helpful in maintaining healthy gum and lip tissue. L-lysine intake may be inadequate in low-protein diets.

Glutamine is an amino acid that serves as a building block for proteins. It is also an important fuel for immune cells that promote optimal immune function.
What Is L-Glutamine?
Glutamine supplements are often associated with serious athletes, but it can be beneficial for anyone who wants to not only maintain muscle health, but also immune and gut health.
Glutamine is the most abundant free amino acid found in the body.
L-Glutamine Benefits
- Supports healthy muscle mass
- Helps maintain energy levels under heavy stress
- Helps maintain optimal immune function & gut health
Glutamine can be found circulating in the blood, as well as stored in the skeletal muscles and liver, in concentrations ranging from 10- to 100-fold higher than any other amino acid.
Glutamine is utilized in a number of vital functions, including protein synthesis and production of the nucleotide units that make up DNA and RNA. Because of its importance in many cellular functions, glutamine is consumed at especially high rates during activities involving intense exercise. It is an important energy source for cells lining the gut and immune cells and critical for healthy gut and immune function. It is also a precursor of the brain neurotransmitter glutamate.
The function of glutamine in stimulating glycogen synthase, the enzyme that controls the synthesis and storage of glycogen fuel in muscles and liver, may provide a mechanism by which glutamine supplements promote enhanced fuel stores.
People who engage in heavy exercise can affect their glutamine levels, causing stress to their body and immune systems. Supplementing with glutamine can be important to a serious athlete, someone challenged with muscle loss or someone who wants to help maintain optimal immune function and energy level under heavy stress.
Studies indicate supplementing with glutamine can effectively raise glutamine concentrations in circulation and in muscle tissue, promote a healthy inflammatory response and support antioxidant defenses to maintain muscle health.

Biogeek® Creatine Powder
Performance • Strength • Brain Support
Biogeek® Creatine Powder is a pure, single-ingredient, vegan creatine monohydrate supplement formulated to support strength, endurance, and mental clarity. Each serving provides 5 grams of high-quality creatine to help fuel your body, build and maintain lean muscle, and promote healthy energy levels.*

How It Works
Creatine is a naturally occurring amino acid derivative that supports the production of adenosine triphosphate (ATP) — the body’s main energy molecule. ATP fuels every muscle contraction and brain signal. During exercise, ATP stores become depleted; creatine helps replenish them, enabling improved performance, quicker recovery, and sustained energy output. It also promotes cellular hydration and muscle volume, helping to build and preserve lean mass.*
Suggested Use
As a dietary supplement, take 5 g (approximately 1 scoop) daily, or as directed by your healthcare practitioner. Mix with water, juice, or your favorite beverage. Can be used pre- or post-workout.

Supports muscle, intestinal and immune function
This amino acid is a primary energy source for your intestinal cells and is widely present in muscle tissue. Supplementation may be beneficial during physiological stress.† Supplementing with L-glutamine may also support a healthy intestinal lining and immune function.†
Glutamine is the most abundant amino acid in your body and helps form other amino acids, glucose, protein, and glutathione. Stored in your muscles, it is the primary metabolic fuel for cells in your small intestine, fibroblasts that make collagen, and cells in your immune system.† Supplementing with glutamine can support cells that make up your gut lining, resulting in less intestinal permeability and better immune function.
