Consumer advice
This is a reasonable product if you prefer liquid supplements and want a convenient all-in-one sleep/recovery formula. Before buying, check the supplement facts panel for the exact mg of magnesium glycinate and L-theanine — magnesium needs ~200-400mg elemental and L-theanine needs ~200mg to be effective. If those doses are present, the $21-25 price is defensible. If not, you'd be better served buying magnesium glycinate ($10-15) and L-theanine ($10-15) separately at verified doses. The tart cherry dose (32.6g per serving) is notably high and likely therapeutic. Chamomile and lemon balm are pleasant additions but have weaker standalone sleep evidence.

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.
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 25 mg.

Chamomile
NCCIH says chamomile is likely safe orally in amounts found in teas and other foods, and possibly safe short term for medicinal use. Side effects are uncommon, but allergic reactions, estrogen-like effects, and drug interactions are noted.
Possible side effects
- Side effects are uncommon and may include nausea, dizziness, and allergic reactions in some people.
- Chamomile used near the eyes might cause eye irritation.
Serious risks
- Allergic reactions can include severe hypersensitivity reactions and anaphylaxis.
- Chamomile might worsen conditions sensitive to estrogen, such as breast or uterine cancer.
Avoid or ask a doctor first if
- People allergic to related plants are more likely to react to chamomile.
- Little is known about safety during pregnancy or breastfeeding.
- Chamomile might have some of the same effects as estrogen.
Medication interactions
- Taking chamomile with birth control pills might decrease the pills' effects, according to preliminary studies.
- Interactions have been reported with warfarin and some drugs metabolized by the liver; sedatives are a theoretical concern.
- People taking any medicine should talk with a health care provider before using chamomile.
