I take all of these once per week to hedge my bets:
1. (apo)Lactoferrin
Everything indicates that this supplement is a slam dunk, yet it's rarely discussed. Probably the best way to manage iron.
2. Astaxanthin
Eye health + extremely potent antioxidant.
3. NAC
Seems to have a whole host of benefits and perfect before a night out to prevent hangover.
4. Tocotrienols
Why not? Vitamin E is one of the most prevalent deficiencies.
