Vitamin C Dose for Collagen: 200–1,000 mg and Training Timing
Vitamin C for longevity and collagen synthesis: 200–1,000mg dosing saturation, pairing with gelatin/collagen before training, and NOW C-1000 on Amazon.
Collagen cofactor, colds, liposomal marketing, and why 1g is enough for almost everyone
Vitamin C is an essential cofactor for collagen and a water-soluble antioxidant. Deficiency is rare on mixed diets; megadoses do not buy lifespan. This guide covers food vs ascorbic acid, the cold literature, and when a cheap NOW capsule is rational next to collagen powder.

Key Takeaways
- 1Eat produce first; supplement when travel or winter diet is sad
- 2200–500mg covers most people; 1g is a convenient capsule, not a better outcome
- 3Colds: prevention evidence is weak; duration may shorten slightly in some trials
- 4Liposomal C is optional if cheap ascorbic acid wrecks your gut
Who this is for
- ·Anyone stacking collagen without the cofactor
- ·Readers tempted by $60 liposomal bottles
- ·Oxalate-stone patients who need a clinician, not a gram at bedtime
What It Actually Does
Strong EvidenceHumans lost the gene to make ascorbic acid. We need it for collagen cross-links, carnitine, and several neurotransmitters. Scurvy is the deficiency disease — not ‘suboptimal glow.’
Peppers, kiwi, citrus, and broccoli cover the RDA easily. Capsules are for gaps, not identity.
Colds and Megadoses
Moderate EvidenceCochrane-style reviews find little prevention benefit in the general public; some shortening of duration, especially in people under extreme physical stress.
Pauling-era grams-per-hour protocols are not a longevity stack. Unused C is excreted. High doses raise diarrhea and oxalate-stone risk.
With Collagen
Moderate EvidenceIf you buy collagen peptides, a small C dose with the shake is more rational than a fourth flavor of powder. NOW C-1000 can be split.

SupplementsZinc Picolinate Dosage for Men: 15mg vs 30mg
For most men, 15 mg of elemental zinc picolinate with food is the maintain dose. Use 30 mg if you train hard, sweat a lot, or eat little meat. Do not stay above 40 mg a day for months — that is where copper runs low. A 50 mg capsule is a short repletion, not the daily plan. Thorne sells the 15 mg and 30 mg sizes; the buying notes are in [best zinc](/guides/best-zinc).
