Below is general information about the safety of the known ingredients contained in the product Splyce. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
LIKELY SAFE ...when used orally and appropriately in doses of up to 6 grams daily (698,10631). However, some patients have used up to 20 grams daily with apparent safety (698). Betaine anhydrous is available as an FDA-approved prescription product (Cystadane) (698), and also as a supplement. The European Food Safety Authority states that betaine anhydrous is safe to use in doses up to 6 mg/kg daily, in addition to usual dietary intake (105548). There is insufficient reliable information available about the safety of topical betaine anhydrous.
CHILDREN: LIKELY SAFE
when used orally and appropriately in doses up to 150 mg/kg daily (698).
However, some patients have used up to 20 grams daily with apparent safety (698). Prescription betaine anhydrous (Cystadane) is approved by the US FDA for use in infants and children (698).
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when used orally and appropriately. BCAAs 12 grams daily have not been associated with significant adverse effects in studies lasting for up to 2 years (68,72,73,74,10117,10146,10147,37120,92643,97531,103351,103352). ...when used intravenously and appropriately. BCAAs are an FDA-approved injectable product (13309).

CHILDREN: POSSIBLY SAFE
when larger, supplemental doses are used orally and appropriately for up to 6 months (13307,13308,37127).
PREGNANCY:
Insufficient reliable information available; avoid using amounts greater than those found in food.
Although adverse effects have not been reported in humans, some animal research suggests that consumption of supplemental isoleucine, a BCAA, during the first half of pregnancy may have variable effects on birth weight, possibly due to abnormal placental development (103350).
LACTATION:
Insufficient reliable information available; avoid using amounts greater than those found in food.
Although the safety of increased BCAA consumption during lactation is unclear, some clinical research suggests that a higher concentration of isoleucine and leucine in breastmilk during the first 6 months postpartum is not associated with infant growth or body composition at 2 weeks, 2 months, or 6 months (108466).
LIKELY SAFE ...when used in amounts found in foods. Typical daily intakes for adults range from 40-400 mg (101471).
POSSIBLY SAFE ...when used orally and appropriately in medicinal amounts. Taurine 2-4 grams daily in two or three divided doses has been used safely in studies lasting up to 3 months (5248,5271,8217,8221,10454,77147,95612,98337,104165,104167). Higher doses of taurine 6 grams daily have been used safely in studies lasting up to 4 weeks (98336,98337). A risk assessment of orally administered taurine has identified an Observed Safe Level (OSL) of up to 3 grams daily for healthy adults (31996).
CHILDREN: LIKELY SAFE
when used in amounts found in foods.
CHILDREN: POSSIBLY SAFE

BCAAs in large doses can reduce the effects of levodopa.
Details
BCAAs may compete with levodopa for transport systems in the intestine and brain and decrease the effectiveness of levodopa (66,2719). Small clinical studies how that concomitant ingestion of protein or high doses of leucine or isoleucine (100 mg/kg) and levodopa can exacerbate tremor, rigidity, and the "on-off" syndrome in patients with Parkinson disease (3291,3292,3293,3294).

Theoretically, taurine might increase the risk of hypotension when taken with antihypertensive drugs.
Details
|
Theoretically, taurine might reduce excretion and increase plasma levels of lithium.
Details
Taurine is thought to have diuretic properties (3647), which might reduce the excretion of lithium.

Below is general information about the adverse effects of the known ingredients contained in the product Splyce. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
General
...Orally, betaine anhydrous is generally well tolerated.
Most Common Adverse Effects:
Orally: Body odor, diarrhea, elevated cholesterol levels, GI distress, nausea, vomiting.
Serious Adverse Effects (Rare):
Orally: Cerebral edema.
Cardiovascular ...Betaine anhydrous might have adverse effects on the plasma lipid profile. Some studies have reported a 3% to 4% increase in total and low-density lipoprotein (LDL) cholesterol levels with betaine anhydrous 6 grams daily (16452,16455,16456,34904). A meta-analysis of 6 studies in adults, some with obesity and/or prediabetes, shows that taking betaine anhydrous 4-6 grams daily for 6-24 weeks is associated with a mean increase in total cholesterol of 4 mg/dL, with no significant change in LDL cholesterol, high-density lipoprotein (HDL) cholesterol, or triglyceride levels (105814). Another meta-analysis of 12 studies, some in healthy adults and others in adults with various disease states, shows that taking betaine anhydrous 1.5-20 grams daily for 2-52 weeks is associated with a mean increase in total cholesterol of 14 mg/dL, and a mean increase in LDL cholesterol of 10 mg/dL, with no change in triglyceride or HDL cholesterol levels (105813).
Gastrointestinal ...Orally, betaine anhydrous can cause vomiting, nausea, GI distress, and diarrhea (698,10631,34888,34928,111374).
Neurologic/CNS ...When used orally to treat homocystinuria due to cystathionine beta-synthase deficiency, elevated plasma methionine concentrations can occur following use of betaine anhydrous, which might lead to cerebral edema (698,111374).
Other ...Orally, betaine anhydrous can cause body odor (698,10631).
General
...Orally or intravenously, BCAAs are generally well tolerated.
Most Common Adverse Effects:
Orally: Abdominal distension, diarrhea, nausea, vomiting.
All routes of administration: High doses can lead to fatigue and loss of motor coordination.
Cardiovascular ...Orally, a single case of hypertension following the use of BCAAs has been reported (37143).
Dermatologic ...Orally, a single case of skin blanching following the use of BCAAs has been reported (681). It is not known if this effect was due to use of BCAAs or other factors.
Gastrointestinal ...Orally, BCAAs can cause nausea, vomiting, diarrhea, and abdominal distension. Nausea and diarrhea has been reported to occur in about 10% of people taking BCAAs (10117,37143,92643,97531).
Neurologic/CNS ...Orally and intravenously, BCAAs can cause fatigue and loss of motor coordination due to increased plasma ammonia levels (693,694,10117). Short-term use of 60 grams of BCAAs containing leucine, isoleucine, and valine for 7 days in patients with normal metabolic function seems to increase levels of ammonia, but not to toxic plasma levels (10117). However, liver function should be monitored with high doses or long-term use (10117). Due to the potential of increased plasma levels of ammonia and subsequent fatigue and loss of motor coordination, BCAAs should be used cautiously before or during activities where performance depends on motor coordination (75). Orally, BCAAs may also cause headache, but this has only been reported in one clinical trial (681).
General
...Orally, taurine is generally well-tolerated when used in typical doses for up to one year.
Most Common Adverse Effects:
Orally: Constipation, diarrhea, and dyspepsia.
Serious Adverse Effects (Rare):
Orally: Hypersensitivity reactions in sensitive individuals. Case reports raise concerns for serious adverse effects, but these reports have involved energy drinks containing taurine and other ingredients. It is unclear if these adverse effects are due to taurine, other ingredients, or the combination.
Cardiovascular ...Decreased heart rate and increased blood pressure have been reported following the co-administration of taurine and caffeine, although the effects of taurine alone are unclear (77088). In healthy individuals, consumption of energy drinks containing taurine increased platelet aggregation and decreased endothelial function (77151). A case of cardiac arrest following strenuous exercise and an excessive intake of energy drinks containing caffeine and taurine has been reported (77136).
Endocrine ...Orally, taurine has been reported to cause hypoglycemia (77153).
Gastrointestinal ...Orally, constipation has been reported following the administration of taurine (77231). Dyspepsia has also been reported after oral taurine use (104165).
Hematologic ...In clinical research, taurine reduced platelet aggregation (77245). A case of massive intravascular hemolysis, presenting with confusion, dark urine, dyspnea, emesis, and fever, has been reported following the administration of a naturopathic vitamin infusion containing taurine, free amino acids, magnesium, and a vitamin B and D complex (77177). However, the effects of taurine alone are unclear.
Immunologic ...A case report describes a hypersensitivity reaction in a female patient with a history of allergies to sulfonamides, sulfites, and various foods, after ingestion of taurine and other sulfur-containing supplements. The amount of taurine in the products ranged from 50-500 mg per dose. The allergic reaction recurred upon rechallenge with taurine 250-300 mg (91514).
Neurologic/CNS
...In a case study, encephalopathy occurred in a body-builder who took approximately 14 grams of taurine in combination with insulin and anabolic steroids.
It is not known if this was due to the taurine or the other drugs taken (15536).
Cases of seizures following the consumption of energy drinks containing taurine have been reported (77105,77196). In clinical research, taurine has been reported to cause drowsiness and ataxia in epileptic children (77241).
Psychiatric ...In a case report, a 36-year-old male with adequately controlled bipolar disorder was hospitalized with symptoms of mania after consuming several cans of an energy drink containing taurine, caffeine, glucuronolactone, B vitamins, and other ingredients (Red Bull Energy Drink) over a period of four days (14302). It is unknown if this effect was related to taurine.
Pulmonary/Respiratory ...In human research, an exacerbation of pulmonary symptoms of cystic fibrosis has been associated with taurine supplementation, although this could also be caused by progression of the disease (77231).
Renal ...A case of acute kidney failure has been reported following the concomitant intake of 1 liter of vodka and 3 liters of an energy drink providing taurine 4. 6 grams, caffeine 780 mg, and alcohol 380 grams (77185).
