The v1 formula
Nothing is hidden behind a proprietary blend. Members of the Circle vote on what stays, what changes, and what gets cut before v1 ships.
Locked in for the first shipment, pending final manufacturing checks.
2.5 g · Preserve lean muscle
Why it's here
GLP-1 users often lose meaningful muscle mass alongside fat. Leucine is the primary trigger for muscle protein synthesis and helps protect lean tissue when appetite and protein intake drop.
Evidence
Multiple RCTs show 2–3 g of leucine per meal increases muscle protein synthesis in adults, including in calorie-restricted states.
3 g · Strength & cognitive support
Why it's here
One of the most-studied supplements in existence. Helps maintain strength and power output during reduced food intake, with emerging cognitive benefits.
Evidence
Over 700 peer-reviewed studies. ISSN position stand confirms safety and efficacy at 3–5 g daily.
1,000 IU · Bone, immune & mood
Why it's here
Deficiency is widespread in northern Europe and worsens with reduced food variety. Supports calcium absorption, immune function, and mood regulation.
Evidence
EFSA-approved health claims for bone, immune, and muscle function. NHS recommends supplementation in autumn/winter.
90 mcg · Directs calcium to bone
Why it's here
Pairs with D3 to direct calcium toward bone rather than soft tissue. Particularly relevant when bone turnover may be affected by weight loss.
Evidence
RCTs show MK-7 improves bone mineral density markers over 12+ months at this dose range.
200 mg · Sleep, nerves & muscle
Why it's here
Glycinate form is well-absorbed and gentle on the gut — important when GI tolerance is already a concern. Supports sleep quality and reduces cramping.
Evidence
EFSA-approved claims for muscle function, nervous system, and reducing tiredness. Glycinate form has best tolerability profile.
1,000 mg combined · Heart, brain & inflammation
Why it's here
Reduced overall food intake often means reduced oily-fish intake. EPA and DHA support cardiovascular and cognitive health and help moderate inflammation.
Evidence
EFSA-approved heart-health claim at 250 mg/day. Meta-analyses support 1 g/day for cardiovascular outcomes.
Strong case, under final review. Members are voting now.
5 g · Digestive regularity
Why it's here
GLP-1 medications slow gut motility, which can cause constipation. Soluble fibre helps regularity without harsh stimulants.
Evidence
Cochrane reviews support psyllium for chronic constipation. Well-tolerated at 5–10 g daily with adequate water.
250 mg · Liver & cognitive support
Why it's here
Choline is essential for liver health and is often under-consumed. Citicoline form has cognitive benefits in early evidence.
Evidence
EFSA-approved claims for normal liver function and lipid metabolism. Citicoline trials show modest cognitive effects.
On the table, but evidence is still being weighed.
10 g · Skin, hair & joint comfort
Why it's here
Rapid weight loss can affect skin elasticity and joint comfort. Collagen peptides are popular but evidence remains mixed at the dose required.
Evidence
Some RCTs show benefits at 10 g+ daily over 12 weeks for skin elasticity and joint pain. Quality varies.
