Vitamin B12 is present in foods of animal origin, including dairy products and eggs. Thus, vegetarians are more susceptible to a dietary deficiency of this important nutrient. Likewise, vitamin B12 serum concentrations are reported to be significantly lower in elderly population groups compared to younger groups. It is estimated that 10% to 30% of individuals over the age of 50 have low stomach acid secretion which results in decreased bioavailability of vitamin B12 from food.
Methylcobalamin is the form of vitamin B12 active in the central nervous system. It is essential for cell growth and replication. In some people the liver may not convert cyanocobalamin, the common supplemental form of vitamin B12, into adequate amounts of methylcobalamin needed for proper neuronal functioning. Methylcobalamin may exert its neuroprotective effects through enhanced methylation, acceleration of nerve cell growth, or its ability to maintain already healthy homocysteine levels.
Lactoferrin is a supplement in the immune-boosting arsenal. It is a versatile substance found in mother's milk that plays an important role in the immune system response. Though human colostrum ("first milk") has the highest concentration, followed by human milk, then cow's milk, lactoferrin is found throughout the human body. It can help promote beneficial bacterial flora growth in the intestines. So by adding it to your regimen, you powerfully support both your immune health and your GI tract at the same time. Lactoferrin also promotes and supports natural resistance, provides protection for healthy cells and modulates immune function.
The suggested dose is one 300 mg capsule per day. This means each 60 capsule bottle will last for two months. Life Extension consumers obtain this premium form of lactoferrin (called apolactoferrin) for less than conventional lactoferrin supplements. So be sure to give your immune health the support it needs with Lactoferrin Caps.
Vitamin B6, or pyridoxine, is an important component of the coenzyme PLP, which metabolizes amino acids.1-4 Because of its amino acid transfer ability, the body can produce non-essential amino acids from available amino groups, as well as metabolize protein and urea. Vitamin B6 is essential because of its participation in more than 140 enzymatic reactions, including protein metabolism, conversion of tryptophan to niacin, and neurotransmitter function, among others.
Found in foods such as eggs, brewer's yeast, carrots, chicken, fish, brown rice, whole grains, and cabbage, vitamin B6 (along with B12 and folic acid) plays a beneficial role in maintaining already healthy homocysteine levels within normal range.
Your skin makes vitamin D3 via exposure to direct sunlight. Plants get their nourishment from the sun as well, which inspired us to create a vitamin D3 supplement that is completely free of animal sources or byproducts: not in the 100% vegan capsule, nor in the nutrient inside.
For vegans and vegetarians, getting the right nutrition can pose unique challenges. So we created a vegan-friendly 125 mcg Vitamin D3 formula.
Vegan Vitamin D3 Benefits
Promotes cognitive health & healthy bone density
Helps maintain a healthy immune response
Contains absolutely no animal by-products
Getting Enough of the Sunshine Vitamin
Vitamin D is called the sunshine vitamin because your skin manufactures it when exposed to sunlight, but that shouldn’t be your only source. A vitamin D supplement goes a long way. We recommend about 125 mcg (5000 IU) to 200 mcg (8000 IU) of vitamin D3 a day. If your multivitamin already delivers 25-75 mcg (1000–3000 IU) of vitamin D, vitamin D3 125 mcg (5000 IU) is perfect for achieving optimal levels.
