Stress support, adrenal support, nervous system support, energy metabolism
Adults with busy, high-pressure schedules or those seeking daily adaptogen-style support without caffeine.
Take 1 capsule daily with water about 15 minutes before a meal; taking with food may improve comfort if you are sensitive to minerals.
Non-GMO; Suitable for vegetarians; Not manufactured with yeast, wheat, gluten, soy, milk, egg, fish, shellfish or tree nut ingredients; Produced in a facility that processes these allergens.
Phosphoserine is a phosphorylated form of serine that may contribute phosphate groups and serve as a precursor to phospholipid-related compounds involved in cell signalling and stress-response pathways.
Caution: May affect individuals sensitive to phosphate load; take with food if stomach discomfort occurs.
L-Serine is a non-essential amino acid used to build proteins and phospholipids, supporting neurotransmitter and membrane function related to stress adaptation.
Caution: Amino acids may cause mild digestive upset in some people; reduce dose or take with food if needed.
Magnesium acts as a cofactor in nervous system and energy enzymes, which may help calm excitatory signalling and support stress resilience.
Caution: High doses can loosen stools; separate from certain medications as minerals can affect absorption.
Calcium contributes to nerve signalling and muscle function, and in phosphate salts it also supplies phosphate that participates in energy metabolism.
Caution: Space away from iron or thyroid medications as calcium can reduce their absorption.
Phosphorus as phosphate supports cellular energy production and buffering systems that are engaged during stress responses.
Caution: Excess phosphate may be unsuitable for those on restricted phosphate diets; take with water.
Phosphoserine and L-serine provide serine backbones and phosphate groups that relate to membrane and signalling processes involved in stress responses. Magnesium, calcium, and phosphate minerals support enzyme activity, nerve transmission, and energy metabolism, complementing the amino acid components for overall adaptogen-style support.
Label Warning: If pregnant or nursing, consult your doctor before use.
Who should be cautious: People with sensitivity to phosphate or magnesium sources may wish to start with caution. Those using thyroid medications or certain antibiotics may need to separate dosing from calcium and magnesium to avoid reduced absorption; discuss timing with a healthcare provider.
Storage: Store in a cool, dry place or refrigerate. Keep out of reach of children.
This product is guaranteed authentic and backed by our easy returns and refunds policy. Details
Magnesium supports muscle relaxation, nervous system function, and stress modulation. Paired with adaptogens, it may enhance resilience to occasional stress and promote a calm, steady energy.
