Consumer advice
If your main goal is hormonal/cycle support, the inositol dose and ratio here is genuinely well-matched to the research, so this isn't a scam ingredient-wise. But don't expect the turmeric, hyaluronan, or glutathione amounts to visibly change your skin or inflammation - those are token doses. Before subscribing, compare the cost to buying a 40:1 inositol powder alone (often $25-35/month), since that's likely the ingredient doing most of the real work here. Read the fine print on the "89%/95%" stats - those are self-reported survey numbers from existing customers, not a controlled trial, so treat them as anecdote, not proof.

Safety & side effects
What NIH says about the ingredients in this product. This describes the ingredients, not tests of this product, and it is not medical advice. Ask a doctor or pharmacist first if you take medication, are pregnant or nursing, or have a health condition.
Turmeric
NCCIH says conventionally formulated oral turmeric or curcumin is likely safe in recommended amounts for up to 2 or 3 months. Highly bioavailable curcumin products have been linked to liver damage, and turmeric supplements during pregnancy may be unsafe.
Possible side effects
- Oral turmeric can cause digestive effects such as nausea, vomiting, reflux, stomach upset, diarrhea, or constipation.
- Topical curcumin can cause hives or itching.
Serious risks
- Liver damage has been reported in some people who used curcumin products with increased bioavailability.
- Highly bioavailable curcumin formulations may harm the liver.
Avoid or ask a doctor first if
- Turmeric supplements during pregnancy may be unsafe.
- Little is known about safety of turmeric above food amounts while breastfeeding.
- If liver damage symptoms appear, stop turmeric or curcumin products immediately and talk with a health care provider.
Medication interactions
- The source gives a general warning that some herbs and medicines interact in harmful ways; talk to a provider before using any herbal product if you take medicine.
Carnitine
Carnitine has no established tolerable upper intake level. Doses of about 3 g/day of supplements can cause digestive upset and a fishy body odor, and some research links gut bacteria's breakdown of unabsorbed carnitine to possible CVD risk, though the implications are not well understood.
Possible side effects
- About 3 g/day of carnitine supplements can cause nausea, vomiting, abdominal cramps, diarrhea, and a fishy body odor.
Serious risks
- Some research indicates gut bacteria turn unabsorbed carnitine into TMAO and gamma-butyrobetaine, which might increase CVD risk; the implications are not well understood.
- Carnitine can cause seizures in people with seizure disorders.
Avoid or ask a doctor first if
- People with uremia can get muscle weakness, and people with seizure disorders can have seizures, from carnitine.
Medication interactions
- Several types of medications have the potential to interact with carnitine supplements.
- People taking medications regularly should discuss their carnitine intake with their healthcare providers.
Source: NIH Office of Dietary Supplements, Carnitine: Fact Sheet for Health Professionals
Chromium
The FNB found no adverse effects linked to high chromium intakes from food or supplements, so it set no UL. It still said caution may be warranted because the data are limited.
Serious risks
- Isolated case reports link chromium supplements to several problems, including liver dysfunction and renal failure.
- The FNB said caution may be warranted because data are limited, and high intakes could have adverse effects.
Avoid or ask a doctor first if
- People with renal or liver disease might be susceptible to adverse effects from high chromium intakes.
Medication interactions
- Several types of medications have the potential to interact with chromium supplements.
- People taking medications regularly should talk with their health care providers about their chromium intakes.
Source: NIH Office of Dietary Supplements, Chromium: Fact Sheet for Health Professionals
Magnesium
Magnesium from food poses no health risk in healthy people, because the kidneys clear the excess. High doses from supplements or medications can cause diarrhea, nausea and abdominal cramping, and very high doses can lead to toxicity.
Possible side effects
- High doses from supplements or medications can cause diarrhea, nausea, and abdominal cramping.
- Magnesium carbonate, chloride, gluconate, and oxide are the forms most commonly reported to cause diarrhea.
Serious risks
- Very high doses can lead to magnesium toxicity, with low blood pressure, vomiting, difficulty breathing, irregular heartbeat, cardiac arrest and other signs.
- A few cases of fatal hypermagnesemia have been reported.
- Very large doses of magnesium-containing laxatives and antacids have been associated with magnesium toxicity.
- The risk of toxicity increases with impaired kidney function or kidney failure.
Avoid or ask a doctor first if
- People with impaired kidney function or kidney failure face higher risk of magnesium toxicity.
- People taking medications regularly should discuss their magnesium intake with their health care providers.
Medication interactions
- Magnesium may interact with oral bisphosphonates, tetracyclines, and quinolone antibiotics.
- Some medications, including diuretics and proton pump inhibitors, can affect magnesium status.
Upper limit: 350 mg a day for adults 19+. This label lists 100 mg.
Source: NIH Office of Dietary Supplements, Magnesium: Fact Sheet for Health Professionals
Biotin
The FNB set no upper limit for biotin because it found no evidence of toxicity in humans at high intakes. The source says high intakes, possibly even ones above the AI, may pose another type of health risk: falsely high or low lab test results.
Serious risks
- High biotin intakes, possibly even intakes above the AI, may pose a health risk tied to lab testing.
- Biotin beyond recommended intakes can cause clinically significant falsely high or falsely low lab results, depending on the test.
- In a small study of six healthy adults taking 10 mg/day for 1 week, biotin falsely lowered N-terminal pro-brain natriuretic peptide, which could result in a failure to identify congestive heart failure. Thyroid stimulating hormone was also falsely lowered.
- Case reports describe findings falsely indicating Graves' disease and severe hyperthyroidism in patients taking 10–300 mg biotin per day.
- A single 10 mg dose of biotin has interfered with thyroid function tests given within 24 hours.
- Per FDA, a patient with a high intake of supplemental biotin died after a troponin test gave a falsely low result because of biotin interference.
Medication interactions
- Biotin can interact with certain medications, and some medications can have an adverse effect on biotin levels.
Source: NIH Office of Dietary Supplements, Biotin: Fact Sheet for Health Professionals
Vitamin D
Vitamin D toxicity is almost always caused by excessive supplement intake. It can raise blood calcium and, in extreme cases, lead to kidney failure and death. The adult upper limit is 100 mcg (4,000 IU) a day.
Possible side effects
- High blood calcium from vitamin D toxicity can lead to nausea, vomiting, muscle weakness, and other symptoms.
Serious risks
- Toxicity can cause high blood and urine calcium. In extreme cases it may lead to kidney failure, soft tissue calcification, heart rhythm problems, and death.
- Toxicity is almost always caused by taking too much vitamin D through supplements.
Avoid or ask a doctor first if
- The source says people on regular medications should talk with their health care providers about vitamin D intake and status.
Medication interactions
- Vitamin D supplements may interact with orlistat, statins, steroids, and thiazide diuretics.
- Taking calcium supplements with vitamin D supplements may raise the risk of certain adverse effects.
Upper limit: 100 mcg a day for adults 19+. This label lists 25 mcg.
Source: NIH Office of Dietary Supplements, Vitamin D: Fact Sheet for Health Professionals
Elderberry
Raw or unripe elderberries and other parts of the elder tree contain poisonous cyanide-producing substances, and cooking eliminates this toxin. Little is known about use during pregnancy or breastfeeding.
Possible side effects
- Raw or unripe elderberries and other elder tree parts can cause nausea, vomiting, and severe diarrhea.
Serious risks
- Large quantities of the toxin in raw or unripe elderberries and other elder parts may cause serious illness.
Avoid or ask a doctor first if
- Little is known about whether elderberry is safe for health purposes during pregnancy or breastfeeding.
Medication interactions
- People who take any type of medicine are told to talk with their health care provider before using elderberry or other herbal products, because some herbs and medicines interact in harmful ways.
