Vitamin B12 is needed to form red blood cells and DNA. It is also a key player in the function and development of brain and nerve cells.

A mild deficiency may cause no symptoms. But if untreated, it may lead to symptoms such as:

• Weakness, tiredness, or lightheadedness

• Heart palpitations and shortness of breath

• Pale skin

• A smooth tongue

• Constipation, diarrhea, loss of appetite, or gas

• Nerve problems like numbness or tingling, muscle weakness, and problems walking

• Vision loss

• Mental problems like depression, memory loss, or behavioral changes

Vitamin D is a nutrient your body needs for building and maintaining healthy bones by allowing you to absorb calcium. Vitamin D also regulates many other cellular functions in your body. Its anti-inflammatory, antioxidant and neuroprotective properties support immune health, muscle function and brain cell activity.

Deficiency of Vitamin D may cause:

• Muscle pain.

• Bone pain.

• Increased sensitivity to pain.

• Mood changes, like depression.

• A tingly, “pins-and-needles” sensation in the hands or feet.

• Muscle weakness in body parts near the trunk of the body, such as the upper arms, thighs, hips or legs.

Coenzyme Q10 (CoQ10) is a substance that helps convert food into energy. CoQ10 is found in almost every cell in the body, and it is a powerful antioxidant. Antioxidants fight damaging particles in the body known as free radicals, which damage cell membranes, tamper with DNA, and even cause cell death.

Fatigue and muscle weakness may be symptoms of low CoQ10 levels. Significant CoQ10 deficiency may cause severe musculoskeletal and neurologic symptoms. Medications like “statins” for high cholesterol can deplete CoQ10.

A lipotropic nutrient promotes or encourages the export of fat from the liver. Lipotropics are necessary for maintenance of a healthy liver, and for burning the exported fat for additional energy. Common lipotropics include methionine, inositol, choline, carnitine, branched chain amino acids, Vitamin B12, & Vitamin B6.

Benefits of Vitamin C include:

• Immune system support

• Increased energy levels, reduces fatigue

• Prevents cell damage - antioxidant

• Accelerates wound healing

• Essential for collagen production

• Improves skin texture and look

• Production of neurotransmitters

• May reduce the adverse effects of chemotherapy drugs and cancer treatments

Glutathione is an antioxidant produced in cells. It’s comprised largely of three amino acids: glutamine, glycine, and cysteine.

Glutathione levels in the body may be reduced by a number of factors, including poor nutrition, environmental toxins, and stress. Its levels also decline with age.

Researchers at Baylor School of Medicine used a combination of animal and human studies to explore the role of glutathione in weight management and insulin resistance in older individuals. Study findings indicated that low glutathione levels were associated with less fat burning and higher rates of fat storing in the body.

Perhaps the best indicator of the importance of glutathione is that its cellular and mitochondrial levels directly are highly associated with health and longevity. Glutathione depletion has been strongly associated with the diseases and loss of function with aging. It’s clear that adequate availability of glutathione is critical for maintaining health, protecting the body from toxins, and promoting longevity.

Zinc, a nutrient found throughout your body, helps your immune system and metabolism function. Zinc is also important to wound healing and your sense of taste and smell.

Vitamin B complex is composed of eight B vitamins:

• B1 (thiamine)

• B2 (riboflavin)

• B3 (niacin)

• B5 (pantothenic acid)

• B6 (pyridoxine)

• B7 (biotin)

• B9 (folic acid)

• B12 (cobalamin)

Each of these essential vitamins contributes to your overall bodily function.

Vitamin B complex may help prevent infections and help support or promote:

• cell health

• growth of red blood cells

• energy levels

• eyesight

• brain function

• digestion

• appetite

• proper nerve function

• hormones & cholesterol production

• cardiovascular health

• muscle tone

GABA is a vital neurotransmitter, a chemical messenger in your brain, which exerts a "calming" effect on neurons and other cells in the body.

Taurine is an amino acid that occurs naturally within the body - it is one of the most abundant amino acids in the muscle tissue, brain, and other organs in the body.

Taurine plays a role in several essential body functions. Taurine may help to promote healthy metabolism, protect various organs, promote long-term memory storage, and more. Taurine is vital for a person’s overall health.

L-theanine is an amino acid found in tea leaves, particularly green tea and loose-leaf tea, that has several potential health benefits.

Benefits of Theanine may include:

• Better mental focus.

• Improved sleep.

• Relaxation.

• Increased cognitive performance.

• Weight loss.

• Boosting the immune system.

• Reducing blood pressure.

• Supporting certain cancer drugs
