Alpha GPC 50 powder (L-Alpha Glyceryl Phosphoryl Choline) from Earth Made Nutritions Inc. is used in sports nutrition, pharmaceuticals, and cognitive health. Our NSF GMP-certified California facility manufactures this stabilized formulation to reduce pure Alpha GPC's hygroscopicity and preserve bioavailability.
Specifications of note:

Clumping and equipment jams occur during manufacture because pure Alpha GPC (99% potency) absorbs ambient moisture quickly. Our 50% formulation contains the active substance and pharmaceutical excipients (dicalcium phosphate, silicon dioxide):
· Free-flowing granules- No clumping in automatic capsule fillers or blenders
· Moisture resistance- Remains stable at 60% RH for 24+ hours
· Consistent dosing- Uniform particle size for accurate volumetric filling
· Extended shelf life- 24-month stability in sealed containers
This specification has become the standard for solid dosage forms in the nutraceutical industry.

Q: How bioavailable is 50% versus 99% Alpha GPC?
A: The active ingredient offers identical bioavailability. The 50% recipe uses inert excipients that don't alter absorption. Clinical investigations employ both grades interchangeably based on manufacturing needs.
Q: Can this be utilized in beverages or liquid formats?
A: The 50% powder is ideal for solid dosages. Use Alpha GPC 99% oil-dispersible for liquids (different product line).
Q: What's your capability for huge contract manufacturing orders?
A: We stock 5,000+ kg of standard grades regularly. For 10,000+ kilogram dedicated manufacturing runs, contact us 6–8 weeks in advance.
Q: Do you certify organic or non-GMO?
A: We carry conventional and non-GMO Project Verified grades. Organic Alpha GPC is available by special order (500 kilogram minimum).
Q: What paperwork do you give for regulatory compliance?
A: Standard package includes CoA, spec sheet, allergen statement, BSE/TSE certificate, Prop 65 compliance letter. Additional materials (nutritional data, stability studies) available on request.
Q: Can I compare your material to our supplier?
A: Get a comparative sample. We'll match your standards or outperform them (flow rate, moisture resistance, dissolution profile).
