What six pills per serving means
The 6,000 mg on the front of each bottle refers to the full six-pill serving. Dividing by six gives an average of about 1,000 mg of collagen per pill for either bottle. At one labeled serving per day, each bottle supplies 20 days. If you prefer fewer pills, compare the serving sizes in the collagen pills guide.

Cost per serving is the bottle price divided by 20. Each bottle declares 6 g per serving, so cost per gram is the bottle price divided by 120 g. Youtheory was $2.19 less per bottle at the prices checked. Recalculate if you’re comparing a different bottle count or a retailer sale.
Which bottle fits your priorities?
Youtheory fits if you want the lower price and the higher labeled vitamin C amount. NeoCell fits if a label that identifies the collagen as bovine matters more to you. Both have the same six-pill serving and 6 g of declared collagen, so the price and sourcing disclosure are the clearest differences for this purchase.
