5-Hydroxytryptophan
$37.00
$37.00
5-Hydroxytryptophan (5-HTP) is the intermediate metabolite produced when the body initiates the process of converting the essential amino acid L-tryptophan to serotonin. Serotonin levels in the body are associated with the regulation of sleep, mood, aggression, appetite, temperature, sexual behavior, and pain sensation.*
Supplementing with 5-HTP to facilitate serotonin production is preferable to supplementing with L-tryptophan because, unlike L-tryptophan, 5-HTP cannot be shunted into niacin or protein production.* Supplementation with 5-HTP bypasses the conversion of L-tryptophan into 5-HTP by the enzyme tryptophan hydroxylase, the rate-limiting step in the synthesis of serotonin and a step that can be inhibited by a number of factors, including stress, insulin resistance, increasing age, and deficiencies of vitamin C, folate, and iron.
5-HTP is well absorbed when taken orally, with about 70 percent ending up in the bloodstream.*
Intestinal absorption of 5-HTP does not require the presence of a transport molecule and is not affected by the presence of other amino acids; therefore, it may be taken with meals without reducing its effectiveness.* 5-HTP easily crosses the blood-brain barrier and effectively increases central nervous system (CNS) synthesis of serotonin.*
5-HTP has been shown to have a beneficial impact on mood, discomfort associated with fatigue, sleep, and carbohydrate craving.* Numerous studies of individuals with negative mood status have shown significant positive response with 50-300 mg of 5-HTP daily.*
To further facilitate serotonin production, Thorne Research's 5-HTP formula contains pyridoxal 5'-phosphate, the active form of vitamin B6 and the necessary cofactor for the conversion of 5-HTP to serotonin.* 5-HTP is commercially produced by extraction from the seeds of the African plant, Griffonia simplicifolia.
Two Capsules Contain: Vitamin B6 (as Pyridoxal 5'-Phosphate) 6.8 mg. 5-Hydroxytryptophan 100 mg.
Other Ingredients: Microcrystalline Cellulose, Hypromellose (derived from cellulose) capsule, Leucine, Silicon Dioxide.

5-MTHF 1 MG
$24.99
$24.99
5-MTHF is an active, tissue-ready form of folate. It's an essential B vitamin that supports methylation. Many individuals don't get sufficient 5-MTHF because they have intestinal or liver dysfunction or because of their genetic makeup.
Many individuals don't get sufficient 5-MTHF (L-5-Methyltetrahydrofolate), the active form of folic acid, because they have intestinal or liver dysfunction, or because they are among the three out of five Americans whose genetic makeup makes it difficult to convert folic acid into active 5-MTHF. A deficiency of folic acid has been linked to low-birth-weight infants and neural tube defects, which is why the Centers for Disease Control recommends folic acid supplementation for all women of childbearing age. Since 5-MTHF also contributes to the production of serotonin, melatonin, dopamine, epinephrine, and norepinephrine, supplementation supports healthy mood.
Note: 1 mg of 5-MTHF is recommended for fetal support during pregnancy; the 15 mg option is recommended only when directed by a health-care practitioner.
It is important for a woman of childbearing age to get enough folic acid – not just those women who are planning to become pregnant.* Because half of pregnancies are unplanned, any woman who could become pregnant should get enough folic acid every day. Folic acid intake is especially important before conception and during early pregnancy, since its biggest need is during the first trimester – when a woman might not even know she is pregnant. Supplementation with the active form of folic acid – 5-MTHF (L-5 Methyltetrahydrofolate)– is always preferable.
Acting with vitamin B12, 5-MTHF functions as a methyl-group donor, thereby facilitating the conversion of the amino acid homocysteine to methionine. An elevated homocysteine level is a risk factor for a number of undesirable health conditions. Methyl-group donation is vital to many biochemical conversion processes, including the synthesis of serotonin, melatonin, and DNA.
Take 1 capsule one to three times daily or as recommended by a health-care practitioner.

Support heart health, fetal development, nervous system, and mood with 5-MTHF5-
MTHF is a bioactive, methylated form of folate, an essential B vitamin that supports heart, brain, blood, and bone health and is suitable for individuals with MTFHR gene mutations.
Folate is a key component in the body’s methylation cycle, a series of biochemical reactions that play a beneficial role in multiple body systems. Heart and brain health, cellular energy production, fat metabolism, liver detoxification, and bone health all rely on a healthy methylation cycle.
Benefits of Thorne’s 5-MTHF:
Nutritional support for individuals who have an MTHFR gene mutation
Supports production of key neurotransmitters – serotonin, melatonin, dopamine, and epinephrine – natural brain chemicals that play an important role in regulating brain function and mood
Promotes cardiovascular, brain, and bone health by maintaining a healthy methylation cycle and a normal homocysteine level
Supports healthy fetal brain and spinal cord development
Promotes blood and nerve cell health
Features of 5-MTHF:
Suitable for individuals who have an MTHFR gene mutation
Active, methylated folate (5-MTHF) means your body gets the highest benefit with the least additional work
1 mg 5-MTHF is recommended for support of fetal development during pregnancy

Acetyl-L-Carnitine
$30.00
$30.00
Supports cognitive function and healthy nerve sensations in the hands and feet
Acetyl-L-Carnitine enhances neurotransmitter regulation, which can support optimal nerve function.
Thorne's Acetyl-L-Carnitine supports the health of the nerves in the upper and lower limbs and enhances the production of the neurotransmitter acetylcholine, which supports brain function. Acetyl-L-carnitine also helps minimize the discomfort due to alterations in nerve function; for example, in cancer patients undergoing chemotherapy or individual with high blood sugar. Acetyl-L-carnitine is better absorbed and crosses the blood-brain barrier more rapidly than L-carnitine.* Studies have demonstrated its effectiveness in supporting cognitive health and maintaining a positive mood in the elderly, possibly by partially inhibiting the activity of the hypothalamic-pituitary-adrenal axis and lowering chronically elevated cortisol levels, which become elevated during stress.* In addition to acetyl-L-carnitine's support of brain and nerve health, it also promotes healthy sperm count and motility.
This product has been third-party tested and certified to verify what's in the package matches what's on the label and to confirm it contains no unsafe levels of contaminants, such as heavy metals, pesticides, and microorganisms.

Adrenal Cortex
$19.00
$19.00
Adrenal Cortex, made from bovine adrenal cortex tissue, supports healthy adrenal function and promotes an energetic feeling.
The hormones produced in the adrenal cortex are necessary for glucose metabolism, immune function, normal blood pressure, and more. In today's "high-stress" world, lifestyle habits that deprive us of adequate rest and exercise, along with dietary habits fraught with caffeine and refined sugars, can, over time, take their toll on the adrenal glands. Extracts from adrenal cortex tissue can play a valuable role in supporting healthy adrenal glands – and help maintain immune function and promote an energetic feeling. Glandular extracts also support healthy levels of cortisol. Thorne's Adrenal Cortex provides extracts of adrenal cortex tissue for focused support of normal adrenal function.
What part does the adrenal cortex play in maintaining health? The adrenal cortex is responsible for producing a special group of hormones known as corticosteroids. These hormones are comprised of glucocorticoids, mineralocorticoids, and 17-ketosteroids, and are essential for important homeostatic processes throughout the body. Glucocorticoids are necessary for glucose metabolism and immune function. Mineralocorticoids help maintain healthy electrolyte balance and already normal blood pressure. The 17-ketosteroids are associated with sex hormones produced by the adrenal glands.
Take 1 capsule one to three times daily, or as recommended by your health professional.


THORNE RESEARCH
Advanced Bone Support (formerly Oscap)
$27.00
$27.00
Although everyone loses bone density as they age, certain groups are particularly at risk. As many as half of all women in the United States older than 65 should be concerned about maintaining good bone health. Thorne's Advanced Bone Support is a comprehensive bone support supplement. It contains dicalcium malate and dimagnesium malate (two calcium or magnesium molecules each bound to one molecule of malic acid) for enhanced absorption and greater concentration of these important minerals.
Adequate magnesium intake promotes bone density by optimizing the secretion of parathyroid hormone and facilitating active calcium transport to the bones. Advanced Bone Support provides vitamin D3, which facilitates the absorption of calcium; boron, which assists the body's metabolism of vitamin D and estrogen; and B vitamins for healthy methylation, which mediates homocysteine levels, a known risk factor of low bone density.
Research indicates that an elevated homocysteine level in the blood can interfere with the integrity of the bone matrix. Therefore, Advanced Bone Support contains methylcobalamin (an active form of vitamin B12), L-5-methyltetrahydrofolate (the active form of folic acid), and pyridoxal 5'-phosphate (the active form of vitamin B6) for their function in helping to maintain already normal homocysteine levels. To provide a bone health formula that can be used by individuals taking a blood-thinning medication, Advanced Bone Support does not contain vitamin K.
As women age, they experience an overall increase in bone loss compared to bone formation, so a woman's concern about maintaining good bone health should begin well before menopause. Because some bone loss during menopause is inevitable, more bone a woman has "banked" earlier in life, the greater her peak bone mass as she begins to age. Hence, menopausal bone loss will have less of an adverse impact. Even women in the 18-35 year-old age group should make an effort to achieve good bone health, because physical inactivity, low body weight, eating disorders, and poor nutrition during these ages can have adverse impacts on bone health later in life.
Groups at particular risk for bone loss in addition to women include smokers, those with a sedentary lifestyle, individuals who consume excessive sugar, alcohol, or caffeine, small-boned individuals, Caucasians, Asians, and patients on steroid or anticonvulsant therapies for prolonged periods of time.

B-Complex #12
$25.00
$25.00
B Complex #12 supports energy production and healthy neurological function.* Unlike many multi-B vitamins, it contains the active forms of eight water-soluble B vitamins.
B-Complex #12 offers a complete vitamin B complex, with added vitamin B-12 and folate. Supplementing with the active forms of the B vitamins is extremely important to everyone, especially individuals who might not be able to convert non-active B vitamins to their active forms in the liver because of compromised liver function, poorly functioning enzymes, digestive disorders, or increasing age. Vitamin B12 and folate are necessary for normal red blood cell formation, tissue and cellular repair, normal methylation and homocysteine metabolism, and DNA synthesis. Thorne's B-Complex #12 supplies the two active forms of vitamin B12 – adenosylcobalamin and methylcobalamin – as well as the two active forms of folate – folinic acid and 5-MTHF. The other bioactive forms of the B vitamins in each capsule ensures you will get the most bioavailable vitamin B complex available. B-Complex #12 is not derived from yeast.
Most of the B vitamins, with the exception of vitamin B12, are not stored in the body; consequently, they must be acquired daily from the diet in order to maintain optimal health.
Vitamin B12 deficiency can be manifest with varying degrees of mental changes, such as confusion and irritability. Certain prescription medications (for seizures, diabetes, arthritis, and cancer) can cause a deficiency of these important vitamins. The incidence of vitamin B12 and/or folate deficiency is high among the elderly. Pregnant women require an increased amount of folate for proper fetal development. A woman who has a folate deficiency prior to pregnancy can expect that deficiency to be intensified during pregnancy.
B Complex #12 includes eight water-soluble B vitamins: thiamin (vitamin B1); riboflavin/riboflavin 5'-phosphate (vitamin B2); niacinamide (vitamin B3); pantothenic acid (vitamin B5); pyridoxine/pyridoxal 5'-phosphate (vitamin B6); methyl- and adenosylcobalamin (vitamin B12); folinic acid and 5-MTHF (folate); and biotin; plus choline. Although each B vitamin is chemically distinct, they often work synergistically in various biochemical functions throughout the body – from cellular energy production, to healthy red blood cell formation, to healthy neurological function.
A nutritional supplement that contains these active cofactors has enhanced bioavailability, ensuring the body gets the nutrients it needs.
Take 1 capsule one to three times daily or as recommended by your health professional.
